This type of fungus causes a slight discoloration on the hazelnut shell. To increase the marketability of the product, it is essential to separate these defective samples from sound ones. Due to the high color similarity between defective and sound samples, manual separation is prone to significant errors, necessitating an automated process. Furthermore, given the strong feature identification and extraction capabilities of convolutional neural networks (CNNs), this model was employed for the classification task. This study investigated the effect of some important factors such as input image size, flattening methods (global average pooling (GAP) and fully connected layer (FCL)), as well as the number of hidden layers and dropout on the model performance. In examining the effect of input image size on the models’ performance, the highest classification accuracy was obtained with a moderate image size of 128 × 128. Comparing the FCL and GAP methods indicated that the GAP method not only increased training speed but also minimized overfitting, resulting in overall better performance than FCL. The results of the models revealed that the proposed CNN model with four convolutional layers, employing the GAP method, a dropout rate of 0.5, and no hidden layers achieved the highest performance. The results demonstrate that the proposed CNN model effectively classified hazelnuts based on subtle color variations on their shells. It achieved a 0.8% improvement in detection accuracy compared to the manual classification method.</p>\u0000 </div>","PeriodicalId":15951,"journal":{"name":"Journal of Food Quality","volume":"2025 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfq/3350046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582027","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}

The aim of this study was to evaluate the micronutrient composition of complementary flours formulated with the under-valorized local resources. Cricket, tiger nuts, carrots, melon fruit, sweet potato tubers, and baobab fruit pulp were collected in the Far North Region of Cameroon. These biological materials underwent preliminary processing. Complementary flours were formulated with varying amounts of crickets and tiger nuts’ flours added to the constant amount of baobab fruit pulp and sweet potato or carrot tuber or melon fruit pulp flours to obtain 100 g of flour per formula. The total carotenoids, vitamin A, vitamin C, mineral contents, and antinutritional factors of the ingredients and complementary flours were determined using standard methods.

The beans underwent physicochemical characterisation and market value evaluation after fermentation and drying. The results revealed that fermentation in cocoa pods and polypropylene bags was suboptimal. Cocoa pods exhibited low fermentation temperatures, delayed microbial activity, high pH and increased mould proliferation, leading to poor marketability with low cut-test scores. Polypropylene bags retained higher humidity levels, posing a risk for mould contamination, although they showed higher phenolic compound content.

From preliminary tests, the blending ratios were ranged from 65% to 85%, 1% to 20%, and 5% to 15% for wheat, DSF, and MLP, respectively, whereas the baking temperature and time were ranged from 180°C to 200°C and 7–11 min, respectively. The result showed that there were significant differences (<i>p</i> &lt; 0.05) among the formulated samples in nutritional and functional characteristics at different blending ratios, baking temperatures, and baking times. It was also found that the optimum parameters to develop functional cookies in terms of the optimum overall acceptability, protein content, and TPC were when the blending ratio of 75% wheat, 15% DSF, and 10% MLP, with baking temperature at 180°C for 8.75 min.

This study aimed to evaluate the phytochemical composition, antioxidant activities, and nutritional value of two polyherbal nutraceutical formulations, BobyGuard A (BGA) and BobyGuard B (BGB). Formulations were prepared using <i>Curcuma longa, Piper nigrum, Dioscorea bulbifera, Spirulina platensis, Adansonia digitata,</i> and <i>Brassica oleracea</i>.

Proximate composition, vitamin C, and mineral contents were measured, and LC–MS/MS was employed for the tentative identification of bioactive compounds. Antioxidant capacity was assessed using DPPH, OH, FRAP, and TAC assays. Both formulations shared similar qualitative phytochemical profiles, with phenols and flavonoids consistently detected. Quantitatively, BGA showed significantly higher (<i>p</i> &lt; 0.05) levels of vitamin C, manganese, copper, sulfur, tannins, water and alcohol extractives, and total antioxidant capacity.

Measurements were conducted at monthly intervals over a period of 6 months. Results show that Mthikinya, although initially having the highest TCC (56.05 ± 0.22 mg/kg), over MH43A (44.30 ± 1.55 mg/kg) and MH44A (41.65 ± 0.93 mg/kg) experienced the most rapid degradation (<i>p</i> ≤ 0.05). The greater degradation of TCC in Mthikinya was linked to biochemical variations and structural characteristics. PICS bags were slightly better than NWBs in preserving TCC over the 6 months period. The results showed that over a six-month period, PICS bags retained 3.33%, 1.34% and 2.21% higher than NWBs for Mthikinya, MH43A and MH44A, respectively.

A total of 25 male mice BALB/C with 7 weeks of age were used in the experiment. The treatment groups were as follows: (1) Control group (no addition in diet), (2) high lipid (HL, 4 g/mice), (3) high protein (HP, 4 g/mice), (4) HL + bromelain enzyme (HLB, 4 mg/mice), and (5) HP + bromelain enzyme (HPB, 4 mg/mice). Body weight gain rate of the control group was lower than the HL group, and the HLB group had a higher rate than the HPB group (<i>p</i> &lt; 0.01). Liver enzyme levels were higher in the high-fat diet group, but bromelain mitigated this effect. Hematological results showed that the high-fat diet decreased platelet counts while increasing RBC, HGB, and WBC, whereas the protein diet improved platelet formation. Bromelain improved RBC and HGB levels in the high-fat diet, indicating a protective effect. Lipid analysis showed that the high-fat diet elevated harmful lipid levels, while the high-protein diet reduced some. Bromelain improved lipid profiles across both diets, suggesting cardiovascular benefits. The high-fat diet also raised creatinine and urea levels, indicative of kidney impairment, an effect exacerbated by a high-protein diet; however, bromelain supplementation reduced these levels, indicating kidney protection. The study found that high-fat diets increased oxidative stress markers, which were alleviated by bromelain. While PMN viability remained unchanged, phagocytosis rates increased with a high-protein diet and were further enhanced with bromelain in high-fat diets but not in high-protein diets. Moreover, bromelain significantly increased lipase gene expression in the high-fat diet, indicating enhanced fat metabolism, though it lowered lipase expression when combined with protein. Histological analyses illustrated severe liver and kidney damage in the high-fat diet group, marked by liver congestion and fatty degeneration, alongside renal damage, including atrophy and hemorrhage.</p>\u0000 </div>","PeriodicalId":15951,"journal":{"name":"Journal of Food Quality","volume":"2025 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfq/3495251","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482164","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}
