While there are various propolis types across globe, the existence of two main propolis types originating from black poplar and Eurasian aspen poplar have been revealed in Türkiye up to date. This study focused on the chemical characterization and bioactivities of unique propolis samples which showed a distinct chemical profile from the known types of propolis. Accordingly, the botanical origin of this new type of propolis was determined by comparative analysis of hydroalcoholic extracts of propolis with that of <i>Cistus laurifolius</i> extract by HPTLC. Marker compounds such as luteolin, apigenin, quercetin, and 3-<i>O</i>-methylquercetin were detected in both extracts along with an unknown compound. Moreover, this unidentified compound was purified by successive chromatographic methods and its chemical structure was elucidated as 3,7-<i>O</i>-dimethylquercetin by NMR and MS analyses. Besides, LC-MS/MS was used for the quantification of the compounds. The results of bioactivity studies showed that standardized hydroalcoholic propolis extract led to a decrease in nitrite release from LPS-activated RAW264.7 cells at 10 µg/mL indicating its remarkable anti-inflammatory activity. Additionally, propolis extract showed potent anticancer activity against pancreatic cancer cell lines MIA PaCa-2 in both 2D and 3D models in a concentration-dependent manner. The strongest effect on spheroid size change was observed at the concentration of 1 mg/mL.</p></div>","PeriodicalId":549,"journal":{"name":"European Food Research and Technology","volume":"251 1","pages":"151 - 164"},"PeriodicalIF":3.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protein digestibility, analyzed using two different methods and expressed in three different ways, showed a high discrepancy. This suggests that relying on two quantification methods and different ways of result expression can give a broader insight into understanding the protein digestibility of alternative proteins compared to a unilateral approach. The amino acid profiles and digestibility scores of individual proteins revealed that all sources contained limiting amino acids and that none met the dietary requirements. Based on the individual amino acid scores, we conducted theoretical calculations to explore potential protein blends. The optimal blend identified contained no limiting amino acids and included pea protein isolates and corn protein concentrates as the primary components, supplemented with barley protein concentrates, Spirulina, or <i>Nannochloropsis oceanica</i>.

The native triglycerides of this oil are composed mainly of conjugated polyunsaturated fatty acids, in particular α-eleostearic acid C18:3 n– 5 (9c, 11t, 13t) at 60%. This particular fatty acid of CLnA family exerts many activities potentially beneficial for health: anti-inflammatory, anti-leukemic, anti-microbial, anti-tumor, anti-ulcer and anti-diabetic. A process for transforming this acid into its isomers β-eleostearic acid and catalpic acid was explored with the aim of obtaining fractions enriched in β-eleostearic acid C18:3 n– 5 (9t, 11t, 13t). The β-eleostearic acid is a fatty acid of great interest because it is even more reactive and more efficient as antioxidant than α-eleostearic acid due to its higher <i>trans</i> content. Isomerization reaction of α-eleostearic acid in oil was carried out using artificial solar radiation treatment. The enrichment of concentrates in β-eleostearic acid was therefore tested using an eco-fractionation process. This process was carried out in two stages. The first step was the <i>Candida rugosa</i> lipase-catalyzed hydrolysis of triglycerides from native or isomerized <i>Ricinodendron heudelotii</i> oil. The second step was fractionation of the reaction medium obtained after hydrolysis. Triglyceride hydrolysis was complete, with a yield of free fatty acids of over 95% after 2 h of reaction. Treatment of the reaction media yielded 3 lipid concentrates with new chemical compositions of polyunsaturated fatty acids: a first concentrate, derived from hydrolysis of the native oil, composed of 60% α-eleostearic acid and 22% linoleic acid, and two other concentrates derived from fractionation of the hydrolysate of the oil isomerized by radiation. One was composed of 34% linoleic acid, 21% β-eleostearic acid, 11% α-eleostearic acid and 6% catalpic acid, and the last concentrate was composed of over 80% β-eleostearic acid. In addition to offering nutritional benefits similar to those of α-eleostearic acid, β-eleostearic acid also offers an interesting physical property: a very high melting point of 72 °C. Such a polyunsaturated fatty acid, which is solid at room temperature, could prove to be a raw material of choice, particularly in the world of food formulation, where manufacturers are looking for replacements with physical properties close to those of palm oil (the melting point of palmitic acid is 62 °C). <i>Ricinodendron heudelotii</i> oil has thus demonstrated its major role as a source of the triptych of α-eleostearic, β-eleostearic and linoleic fatty acids.</p></div>","PeriodicalId":549,"journal":{"name":"European Food Research and Technology","volume":"251 1","pages":"87 - 98"},"PeriodicalIF":3.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00217-024-04615-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional rice classification methods involving manual inspection can be time-consuming, costly, and error-prone. This study addresses to address this challenge by exploring the potential of machine learning (ML) models for automated and accurate rice classification. The key objectives of this paper are threefold. First, the study evaluates the discriminative power of various morphological features extracted from rice grain images using feature selection methods. Second, it compares the performance of several ML models, including Artificial Neural Network (ANN), Categorical Boosting (CatBoost), Gradient Boosting (GBoost), k-Nearest Neighbours (k-NN), Logistic Regression (LR), Naïve Bayes (NB), Random Forest (RF), Stochastic Gradient Descent (SGD), Support Vector Machine (SVM), and eXtreme Gradient Boosting (XGBoost), in classifying two rice species (Cammeo and Osmancik). Third, the study implements explainable artificial intelligence (XAI) techniques, namely SHapley Additive exPlanation (SHAP) and Individual Conditional Expectation (ICE) plots, to provide transparency and interpretability into the inner workings and decision-making processes of the ML models. The findings indicate that the LR model achieved the highest classification accuracy, with a rate of 93.1%. Feature analysis identified Major Axis Length, Perimeter, Convex Area, and Area as the most influential features in distinguishing between rice species. This study highlights the successful application of advanced ML techniques in automating industrial rice classification, facilitating automated packaging and quality control processes without the need for human intervention. By improving the efficiency of rice classification and reducing reliance on manual labour, this approach offers significant benefits to both the agricultural industry and food production sectors.</p></div>","PeriodicalId":549,"journal":{"name":"European Food Research and Technology","volume":"251 1","pages":"69 - 86"},"PeriodicalIF":3.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00217-024-04614-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Douro wines, originating from the Douro Demarcated Region (DDR) in the North of Portugal, are renowned for their distinct terroir and historical significance. This study investigates twenty-one Douro wine samples (ten white, eleven red) from Baixo Corgo and Douro Superior through Fourier Transform Infrared (FTIR) spectroscopy, Electronic Nose (E-nose) analysis, and Quantitative Descriptive Analysis (QDA). The research has uncovered unique profiles for each sub-region, influenced by factors such as pH, alcohol content, and acidity. Through principal component analysis, the electronic nose analysis identifies separate clusters in red wines and highlights notable aromatic differences in white wines.
