The influence of coastal regions (Gulf of Thailand and Andaman coast) on mangosteen nutrition was explored. The impact of high-level plantation and harvesting (during the fruit season) on mangosteen size and levels of bioactive compounds with high antioxidant capacity in mangosteen flesh was found to be greater than that of flat plantations (during the off-season). Mangosteens grown in flatlands during the fruit season exhibited brighter flesh color and faster ripening compared to those grown in hilly areas. Mangosteens from these results contained carbohydrates ranging from 10.3% to 16.9%. Mangosteens cultivated along the Andaman coast exhibited elevated levels of minerals (K 349 mg/100 g, Na 7.76 mg/100 g, and Mn 1.63 mg/100 g) and vitamins, especially B₂ (0.10 mg/kg), B₆ (0.20 mg/kg), B₁₂ (0.03 mg/kg), and vitamin C (9.25 mg/kg). Conversely, the highest total phenolic content, flavonoids, and antioxidant activity were observed in hilly areas during the fruit season along the Gulf of Thailand (55 mg GAE/100 g, 32 mg QE/100 g, and ABTS values of 88%, respectively). However, mangosteens from hilly areas ripened faster than those from flatlands due to higher total soluble solids and lower fruit firmness. These findings provide valuable insights into the effects of the environment and location, enhancing understanding for year-round mangosteen plantation preparation.</p></div>","PeriodicalId":19294,"journal":{"name":"NFS Journal","volume":"36 ","pages":"Article 100182"},"PeriodicalIF":4.1,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S235236462400021X/pdfft?md5=01a519b429b2c347abf3ef469ce8e4cb&pid=1-s2.0-S235236462400021X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141392171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lower storage modulus values in HPP treated CM yogurts were explained by the lack of long-range β-lactoglobulin bridges at micelle surfaces and the reassociation of pressure-dissociated caseins by hydrophobic interactions.

Therefore, the aim of our study was to develop Buffalo meat sausage by incorporating dehydrated ash gourd peel powder (DAGPP). Four sausage formulations were prepared with three levels of DAGPP inclusion (4%, 8%, and 12%) along with a control sample. DAGPP-incorporated sausages were compared with the control sample in terms of scanning electron micrograph (SEM), crude fiber content, antioxidant activity, total phenolic content, and sensory and textural attributes. The storage studies (at 0 °C) were carried out for analysis of physicochemical properties (moisture content, protein content, ash content, pH and TBA value), color parameters (a*, b* and L* values) and microbiological characteristics. Our results showed that crude fiber content and mineral content increased from 0.74% to 6.33% and 1.94% to 2.74%, respectively, on the first day of the study. TBA value decreased from 0.207 to 0.133 (mg of malonaldhyde/ kg sample) on the 14th day of the study. Microbiological analysis revealed that the total plate count, yeast and mold count reduced from 2.87 to 2.12 log cfu/g and 1.93 to 1.38 log cfu/g, respectively, although no coliform was detected. The highest sensory score was achieved for the sample containing 12% DAGPP ie; 7–9. Based upon our findings, we found that the fortified meat sausages had better microstructure and sensory score, increased nutritional value, crude fiber, shelf life as well as high antioxidant activity. Therefore, DAGPP fortified meat sausage can be considered as one of the important sources for proteins and minerals for the under-nutrition population. However, profiling of the fortified food would be warranted to investigate micronutrients along with other functional characteristics.</p></div>","PeriodicalId":19294,"journal":{"name":"NFS Journal","volume":"35 ","pages":"Article 100179"},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S235236462400018X/pdfft?md5=40796651f47618416dd1f95479071022&pid=1-s2.0-S235236462400018X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140351329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to promote the consumption of two NUS, <em>Ocimum gratissimum</em> and <em>Adansonia digitata</em>, by improving recipes that are traditionally consumed by children aged 6–23 months in the Atacora department. Two (02) improved recipes were formulated: baobab pulp-enriched porridge (BPP) and <em>egusi</em> sauce with african basil leaves and red palm oil (ESBR). Formulation was initially carried out using <em>MINITAB 19</em> mixing software. For each recipe, two factors (two main ingredients of the recipe) were considered for the formulation. The optimized recipes were then tested through a hedonic test with a sample of 66 children in three (03) communes. The nutritional densities of accepted recipes were then determined. Results showed that most of the children liked both recipes formulated. The energy densities of both recipes (1.24 ± 0.03 kcal and 1.89 ± 0.05 kcal/g respectively for BPP and ESBR) met the recommended standards. As for nutritional densities, only iron recommended density was achieved for BPP (4.86 ± 0.12 mg/100 kcal) while for ESBR, in addition to iron density, zinc and vitamin A densities were also achieved. The BPP recipe covered good levels of daily nutritional requirements for one single feed for iron (46.42%) and energy (13.49%) considering the amount consumed by children, whereas the ESBR recipe covered levels of 26.61% for energy, 399.32% for vitamin A, 94.11% for iron and 17.44% for zinc. A better valorization of these species through cooking demonstration sessions addressed to mothers is necessary to ensure the consumption of recipes formulated by communities in general and children in particular.</p></div>","PeriodicalId":19294,"journal":{"name":"NFS Journal","volume":"35 ","pages":"Article 100176"},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352364624000154/pdfft?md5=0867359223dbdcdf3bfeec4d5f926118&pid=1-s2.0-S2352364624000154-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140403800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
