Soursop nectar contains antioxidants and for its conservation the pasteurization is applied. However, this technology decreases its physicochemical properties and bioactive compounds, hence, an alternative is the thermoultrasound which could counter these effects. Therefore, the thermoultrasonicated nectar was compared to a pasteurized one and the in vitro bioaccessibility of antioxidants was estimated. Experimental approach. The soursop nectar (25 %) was elaborated and the response surface methodology was used. The thermoultrasound (TUS) (75-90 % amplitude; 3.15-15 min) was applied, and 2 % stevia and 6 % of agave inulin were added as sweeteners. The microbiological, physicochemical, enzymatic and antioxidant properties were analyzed. The nectar was prepared again and control, optimized TUS and pasteurized were compared. In addition to the aforementioned determinations, microstructure, total dietary fiber (TDF) and in vitro bioaccessibility of antioxidants were performed. Results and conclusions. The response variables that fit the mathematical model were L*, b*, Chroma (C*), total phenolic content (TPC), antioxidant activity by ABTS•+, DPPH• and ferric reducing antioxidant power (FRAP). The L* and DPPH• were influenced by quadratic time and TPC by time (p<0.0001). The optimal TUS condition was 82 % amplitude at 9.15 min and the responses variables were L*, b* and C* (45.48, 3.55 and 3.62, respectively), TPC (38.40 mg GAE/100 mL), ABTS•+ (31.28 μmol TE/100 mL), DPPH• (124.22 μmol TE/100 mL) and FRAP (3.06 μmol Fe (II)/100 mL). In comparison with the pasteurized sample, optimized TUS had high value of TDF (3.53%), L* (45.56) h° (-56.49), TPC (26.63 mg GAE/100 mL), ABTS•+ and DPPH• (22.03 and 129.22 μmol TE/100 mL, respectively), FRAP (3.10 μmol Fe (II)/100 mL) and low pectin methylesterase activity (0.28 PMEU/mL). For in vitro bioaccessibility, the optimized TUS nectar showed high absorption of TPC (15.26 GAE/100 mL) and high values in the antioxidant activity by ABTS (34.92 μmol TE/100 mL) and FRAP (7.88 μmol Fe (II)/100 mL). Novelty and scientific contribution. The thermoultrasound improves the physicochemical properties and in vitro bioaccessibility of antioxidants soursop nectar. On the other hand, as an alternative, this beverage provides low-calorie with prebiotic properties for the benefit of consumer health.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139235045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brain cancer is known to be one of the most difficult types of cancer to be cure. It has serious impact on the lives of diagnosed people due to the insufficient treatment options and their side effects. Thus, the search for novel alternative treatments is ongoing. Melocan (Smilax excelsa L.) and Galdirik (Trachystemon orientalis) are significant contributors to both traditional culinary culture and traditional medicine around Black Sea; however, the evidence regarding their antioxidative and cytotoxic effects remains fairly limited. Experimental approach. This study aimed to determine the antioxidant and cytotoxic activity of Smilax excelsa and Trachystemon orientalis, on the C6 glioblastoma cell line. Smilax excelsa and Trachystemon orientalis plants were dried and extracted; then, the total phenolic content (TPC) and their phenolic profiles were studied. In addition, their Total Antioxidant Status (TAS) and Total Oxidant Status (TOS) were determined by using an assay kit. We also analyzed the total antioxidant activity (TAA) using the DPPH radical scavenging assay and the cytotoxic impact on the glioma cells via the 3-(4,5-dimethylthiazol-2 yl)-2,5-diphenyltetrazolium (MTT) assay. Results and conclusions. According to the results, the water extracts of both Smilax excelsa (1158.17 mg gallic acid eq./100 g DM) and Trachystemon orientalis (262 mg gallic acid eq./0 g DM) had higher TPC than the ethanol extracts. TAA were measured as 192.86 mg and 131.92 Trolox eq./100 g DM for the Smilax excels and Trachystemon orientalis, respectively. The MTT assay revealed that Trachystemon orientalis had a greater cytotoxic effect. In conclusion, the findings of the current study are promising. Novelty and scientific contribution. This is the first study that aimed to evaluate the potential cytotoxic activity of two local Turkish plants, Smilax excelsa and Trachystemon orientalis, against C6 glioblastoma cells and the findings ensure that both plants may be used in the future as good therapeutic agents for treating cancer.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139235504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rowan (Sorbus aucuparia L.) is a small tree in the Rosaceae family with characteristic orange-red fruits. Raw fruits can be used for making jams, juices, and puree, as well as dried ones for teas. In folk medicine, they were used to prevent scurvy and bleeding or as a diuretic and laxative. The aim of this study was to characterize the proximate chemical composition, antioxidant potential, and macro and trace elements of the rowan fruits for their potential use as a functional food. Experimental approach. Fruits were collected in the Alpine-Dinaric region of Croatia in 12 populations. After collection, samples were transported to the laboratory, chopped into small pieces, placed in plastic containers, and stored at -20 ºC until analysis. Proximate chemical composition, including ash, water, cellulose, crude fat, crude protein, was determined according to the official AOAC methods and total carbohydrates as non-structural carbohydrates. Total phenolic content (TPC) and antioxidative capacity (TAC) were also measured. For multielement analysis, fruits were cleaned from the dust, lyophilized, homogenized, and acid digested in a microwave system. Concentrations of elements were quantified using the ICP-MS method. Results and conclusions. The basic constituents in analyzed fruits were 76.53 % of water, 17.45 % of total carbohydrates, 2.98 % of crude proteins, 1.49 % of crude fats, 1.07 % of cellulose, and 1.29 % of ash. On average, the TPC was 932 mg/100 g and the TAC was (60.14±14.48) % and (4.1±1.2) mmol Fe2+/100 g, determined by DPPH and FRAP assay, respectively.

In comparison with the literature, the phenolic and element content of the rowan fruits are similar to that of blueberry and raspberry. Obtained results suggest that the rowan fruits have valuable nutritional properties and could be useful for the fortification in the food industry. Novelty and scientific contribution. The importance of the obtained results is reflected in the completion of the literature gaps on the elemental composition, especially on the content of essential macro- and trace elements, as well as the antioxidant potential of rowan fruits.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135509727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Milk-Clotting Properties and Primary Proteolysis of a Lyophilised Extract from Artichoke Flowers (Cynara scolymus L.)","authors":"Valentina Crosetti, Agustín Sola, Gabriela Grigioni, María José Torres","doi":"10.17113/ftb.61.03.23.8142","DOIUrl":"https://doi.org/10.17113/ftb.61.03.23.8142","url":null,"abstract":"Research background. A few studies have investigated Cynara scolymus enzymes as a substitute for calf rennet in cheese making. They used aqueous extracts prepared by maceration of plant material and stored by freezing. However, it was indicated that lyophilisation is a better alternative to preserve the coagulant properties of plant extracts over a longer period of time, as it is a more controllable, stable and hygienic alternative with a better shelf life that is easier to transport, store and standardise. Experimental approach. We obtained a lyophilised extract of mature artichoke flowers, named CS, which was characterised for its milk-clotting properties at different pH and temperatures. In addition, the potential yield, whey composition and the primary hydrolysis profile of caseins by urea-polyacrylamide gel electrophoresis (PAGE) of mini curds prepared with different doses of coagulant were determined. Results and conclusions. The lyophilised extract was able to hydrolyse casein and showed stable proteolytic activity at pH=6.4 and 37 °C for 50 min, which decreased when the process temperature was increased to 41 and 45 °C and was lost at 70 °C. On the other hand, milk-clotting activity increased significantly (p<0.001) when the temperature increased from 37 to 45 °C and the pH of the milk decreased from 6.8 to 5.8. Potential yield between 10 and 17 % was obtained for the mini curds prepared with the lyophilised artichoke extract, and the casein degradation pattern obtained by urea-PAGE was similar to that of the commercial coagulant. Novelty and scientific contribution. On a laboratory scale, our work has shown that the lyophilised artichoke extract has sufficient proteolytic and coagulant activity to be used as a milk coagulant, i.e. plant rennet, in cheese making as an alternative to animal rennet. As this extract is lyophilised, it has the advantage of being a better alternative in terms of preservation and shelf-life. It offers an innovative way to diversify cheese products and appeal to consumers with different dietary preferences and needs.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135456178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As food production faces major challenges, modern agricultural practices are increasingly focused on conserving resources, reducing negative environmental impacts, and sustainably producing foods high in health-promoting phytochemicals. During the production process, many factors can influence the quality and chemical composition of a final food product. Proper selection of cultivating conditions, especially a balanced nutrition, can significantly increase nutritional value resulting in foods with strong biological and functional properties. Stinging nettle is a rich source of minerals, vitamins, pigments, phenols and other bioactive compounds (BC) and can be consumed as a green leafy vegetable with beneficial effects on human health. Therefore, the aim of this study was to determine the nutritional quality and antioxidant capacity of stinging nettle leaves under the influence of different nutrient solution (NS) treatments during three mowings. Experimental approach. The experiment was performed in a floating hydroponic system, with different treatments of NS application during three mowings. After each mowing, the following treatments were differed: treatment 1 – depletion with water, treatment 2 - supplementation with standard NS, and treatment 3 - correction with nutrients. Of the BC minerals, ascorbic acid, phenols, and photosynthetic pigments content, as well as antioxidant capacity were analyzed spectrophotometrically, while individual phenols were determined by liquid chromatography. Results and conclusions. Different nutrition solution treatments and the number of mowings had a significant influence on the content of the analyzed BC. The highest contents of total phenols (377.04 mg GAE/100 g fm), total flavonoids (279.54 mg CTH/100 g fm), ascorbic acid (112.37 mg/100 g fm), and pigments (total chlorophylls 1.84, and total carotenoids 0.36 mg/g), as well as the highest antioxidant capacity (35.47 µmol TE/g) were recorded in the third mowing, with nutrient solution supplementation. Novelty and scientific contribution. This is the first time that stinging nettle leaves are produced in a floating hydroponic system by controlled plant nutrition. We establish this type of nutrition manipulation during multiple mowings as an innovative technique for the production of novel food with high and improved nutritional value suitable for consumption as green leafy vegetables.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135509735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat stabilised defatted rice bran (HSDRB) is a primary by-product of rice bran oil extraction industries and a nutritious protein source. However, despite the unique nutritional profile of RB protein, the protein-rich by-product, HSDRB is underutilized as low-value animal feed. Research on protein extraction from HSDRB via enzymatic hydrolysis has gained the attention of numerous scholars. However, a cost-effective extraction method is required to mitigate the high expenses associated with enzymes. Therefore, we presented an alternative economical and natural approach for HSDRB protein extraction using solid-state fermentation (SSF) with heterofermentative microbes. Experimental approach. SSF of HSDRB with two kinds of Asian traditional fermentative starters, namely Loog-pang and Koji, were investigated for enzyme production and their efficacy in extracting protein from HSDRB. For this purpose, HSDRB fermentation for 0, 12, 24, 48, 72 and 96 h followed by 24 h hydrolysis was carried out to evaluate the extracted RB protein. Moreover, the microbiome diversity in the fermentative starters was also determined by metagenomic sequencing of 16S rRNA and internal transcribed spacer for bacterial and fungal identification, respectively. Results and conclusions. The microbial community in the fermentative starters revealed the dominance of lactic acid bacteria (LAB) such as Bacillus subtilis in Loog-pang and Streptococcus lutetiensis, Bacillus pumilus, Lactococcus cremoris, Lactococcus garvieae, and Pediococcus pentosaceus in Koji whereas yeast species, Saccharomycopsis fibuligera, and Saccharomyces cerevisiae were dominating the fungal diversity in Loog-pang and Koji starters, respectively. Results suggest that Loog-pang and Koji could produce cellulase, neutral, and acid proteases during fermentation. Despite their microbial diversity discrepancy and the enzyme activity during SSF, both starters were effective in enhancing protein extraction from HSDRB. A positive relationship between the SSF duration and extracted protein was noted. SSF by Loog-pang and Koji after 72 h followed by 24 h hydrolysis was found to extract 65.66 and 66.67 % protein from HSDRB, respectively. The amino acids profile of the protein hydrolysate prepared by non-fermented and fermented method showed no difference and displayed an abundance of glutamic acid, aspartic acids, leucine, arginine, alanine, and glycine amino acids, accounted for approximately 58 % of the total amino acids. Novelty and scientific contribution. Loog-pang and Koji (Thai and Japanese traditional fermentative starters, respectively), were found effective in extracting protein from HSDRB by SSF despite being inexpensive microbial enzyme sources, and future research aimed at scaling up HSDRB protein extraction for usage in industrial applications can rely on our findings.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135509740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the modified food frequency questionnaire (FFQ-m) and Laryngopharyngeal Reflux Health-Related Quality of Life (LPR-HRQL) questionnaires were compared between subjects with and without LPR. There were a total of 100 subjects with LPR and 65 subjects in the control group. The group of subjects with LPR was further randomly divided into two subgroups; the first subgroup was treated with esomeprazole in a twice daily dose of 20 mg combined with dietary and general lifestyle changes instructions, and the other with pantoprazole in a twice-daily dose of 20 mg combined with dietary and general lifestyle changes instructions. Participants were instructed to fill out FFQ-m and LPR-HRQL questionnaires immediately after the initial examination and then after control examinations that were 30 and 60 days after the initial examination.

The field of research on bacterial cellulose production has been growing rapidly in recent years, with the potential for its use in various applications, such as in the medical and food industries. Previous studies have focused on optimizing the production process through various methods, such as using different carbon sources and manipulating environmental conditions. However, further research is still needed to optimise the production process and understand the underlying mechanisms of bacterial cellulose synthesis. Experimental approach. We have used Plackett-Burman and Box-Behnken experimental designs to analyse various factors impact on bacterial cellulose production. The optimized medium was analysed for fermentation kinetics, and the cellulose produced was characterised. This approach was used because it allows for the identification of significant factors impacting bacterial cellulose growth, the optimisation of the culture medium, and the characterisation of the produced cellulose. Results and conclusions. The results indicated that higher sucrose concentrations, higher kombucha levels, and lower symbiotic culture of bacteria and yeast size were the most significant factors for improving bacterial cellulose production, while the others had no relevant impact. The optimized medium showed an increase in the concentration of total phenolic compounds and total flavonoids, as well as relevant levels of antioxidant activity. The pure bacterial cellulose produced showed high water absorption capacity, in addition to high crystallinity and thermal stability. Novelty and scientific contribution. The study makes a significant scientific contribution by optimizing the culture medium to produce bacterial cellulose in a more productive and efficient way. The optimized medium can be used for producing a kombucha-type drink containing a high content of bioactive compounds and the production of bacterial cellulose with high crystallinity and thermal stability. Additionally, the study highlights the potential of bacterial cellulose as a highly water-absorbing material with applications in areas such as packaging and biomedical engineering.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135460935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
