Nutritional composition varied among bamboo sources, with wild bamboo leaves exhibiting higher CP concentrations and lower fiber content (<i>p</i> &lt; 0.05), and higher CP and lower fiber in the bamboo of Xiangling mountains were observed. Almost all species exhibited greater concentrations of CP and PM and lower level of ash in annual bamboo leaves compared to the biennial and perennial (<i>p</i> &lt; 0.05). Moreover, as the bamboo culms matured, there was an increase in acid detergent lignin (ADL), soluble sugar (SS), starch, and gross energy (GE) (<i>p</i> &lt; 0.05). The ash, fiber, and GE contents were increased while the CP and SS were decreased both in leaves and culms among different bamboo species from spring to summer and fall. Moreover, <i>Fargesia</i> displayed lower PM, fiber, and ash levels compared to other species studied, and especially over 20% CP concentration was found in the annual leaves of <i>Bashania spanostachya</i>.

The potato starch was replaced by psyllium husk powder in 20%–40%–60%–80%–100% to improve the technological and sensory properties of the new product. Physicochemical analyses revealed that fiber substitution did not affect protein or fat values but reduced carbohydrate and moisture values. Carbohydrate decrease in psyllium husk samples varied between 39.29% and 71.42% and was detected the most in T5 sample. Moisture reduction varied between 2.46% and 6.01% and decreased as the addition rate increased. Cooking loss and total expressible fluid (TEF) during storage increased with the addition of psyllium husk (especially T2). Cooking loss increased the most in the control sample (4.8%) at the end of storage, while the least loss was in the T3 (3.4%) and T1 (3.5%) samples. Furthermore, during storage, there was a slight decrease in brightness in parallel with the psyllium husk replacement rate, but yellowing indexes increased. Instrumental textural analyses showed that 20%–40% of substituted samples (T1, T2) had similar properties to the control. Changes generally occurred in springiness, stickiness, and chewiness properties when substituting up to 60% psyllium husk. In psyllium husk–substituted samples, adhesiveness, resilience, and hardness decreased during storage, while chewiness increased. Consumer acceptance tests showed that panelists preferred sausages produced from white meat more than others, and sensory acceptability was rated above general liking on a hedonic scale of 6–8. When the technological and sensory properties of the products were evaluated together, it was determined that the acceptability of the 40% substituted (T2) sausage sample showed similar characteristics to the control sample, while the 100% substituted (T5) sample had low acceptance. Overall, the findings indicate that psyllium husk substitution has provided functional properties such as low carbohydrate and fibrousness to chicken sausages without affecting the sensory and textural properties. Psyllium husk powder–contained sausage has the potential to be an alternative meat product for individuals who need particular nutritional purposes.</p>\u0000 </div>","PeriodicalId":15951,"journal":{"name":"Journal of Food Quality","volume":"2025 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfq/3061063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725495","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}

Also, obesity is a high-risk factor for psychological and cognitive diseases. This study used a commercialized collagen peptide probiotic (CPP) containing 12 strains of proprietary probiotics with collagen peptides from fish skin to evaluate weight control, fat formation, blood sugar control, and anxiety behavior effects in mice fed a high-fat diet (HFD) or high-carbohydrate diet (HCD) and compared the effects by the clinical weight loss drug orlistat (ORL). The results showed that CPP was more effective than ORL in slowing the weight gain in HCD- or HFD-fed male mice. However, the effects of CPP and ORL in female mice were slightly different. Regardless of gender, CPP significantly reduced fat formation and improved glucose tolerance caused by HCD or HFD. Blood biochemical analysis also revealed that CPP could restore HCD- and HFD-induced liver and kidney dysfunction in male but not in female mice. The total cholesterol, triglycerides, and leptin concentrations in the blood decreased with CPP compared to the ORL intervention. In addition, CPP alleviated HCD- and HFD-induced anxiety in mice and improved their gut microbiota. This study confirmed that this CPP product has more antiobesity effects and can ameliorate other related damage caused by HCD and HFD than the clinical weight loss drug ORL. Thus, CPP has a strong potential to be widely used for human health promotion and disease prevention.</p>\u0000 </div>","PeriodicalId":15951,"journal":{"name":"Journal of Food Quality","volume":"2025 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfq/8208809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144714820","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 obtained result showed the presence of significant differences between the analyzed banana fruit varieties and growing districts. Overall, the phenolic contents among the banana fruit pulp ranged from 36.28 to 45.34 GAE mg/100 g of banana fruit pulp, while the flavonoids ranged from 3.35 to 7.95 QE mg/100 g.

TFCs show borderline differences across districts, with Debub Bench appearing to have lower TFCs, but a nonsignificant trend for higher TACs and sugar.

To extend the shelf life of eggs, this study developed a chitosan-based composite coating for egg preservation and antibacterial activity. The hydrophobicity and preservation effects of this chitosan composite film were investigated. The experimental results demonstrated that the chitosan composite film exhibited excellent hydrophobic properties. In tests evaluating the preservation performance, eggs coated with the chitosan composite film showed superior results across several parameters. Specifically, the weight loss rate of eggs coated with the chitosan film increased the least over time. Weight loss at 49 days was 26.70% lower in the coated group (7.99%) compared to the uncoated group (10.90%), indicating that the composite effectively sealed the micropores of the eggshell, preventing moisture loss. Moreover, Haugh unit values were higher overall in the coated group than in the uncoated group and were significantly higher on days 14 and 49 than in the uncoated group. The yolk index of the coated eggs exhibited a smaller decline trend and was significantly higher than the control group at specific intervals. The yolk index at Day 49 was significantly higher in the coated group (0.22) than in the uncoated group (liquefaction). Additionally, the pH of egg whites in the coated eggs showed minimal increases over time. Total bacterial count tests revealed that the composite film developed in this study provided antibacterial effects on both the eggshell surface and internal content. Antioxidant assessments of the egg yolk indicated that the composite coating significantly enhanced total antioxidant capacity, superoxide dismutase activity, and slowed down total malondialdehyde production, thereby inhibiting lipid oxidation in the yolk.
