The study investigated how sprouted-papaya seed meal (SPSM) a total of affected the growth and carcase traits of broilers. Based on a completely randomized design, 390 day-old Lohmann broiler chicks were allotted to CONT (chicks provided with control diet), SEED25 (diet containing 2.5% papaya seed meal), GERM1 (diet containing 1% SPSM), GERM25 (diet containing 2.5% SPSM) and GERM5 (diet containing 5% SPSM). Body weight and feed intake of chickens were weekly recorded from 14 to 36 days of age, while birds (six birds per treatment group; 30 birds in total) were slaughtered at day 36. Feeding SPSM up to 5% did not impair ( > 0.05) broilers' growth or feed intake. At 5%, SPSM compromised ( < 0.05) feed conversion ratio (FCR) and reduced breast meat proportion. SPSM at 2.5% in diets had no ( > 0.05) detrimental effects, while papaya seed meal at the same proportion lowered ( < 0.05) final body weight, weight gain, and cumulative feed intake. Overall, SPSM may be incorporated in broiler rations up to 2.5% with no harmful effects on growth, feed intake, FCR and carcase traits of broiler chickens.

Background: Excessive lipogenesis of the skin triggers some dermatological concerns, such as enlarged pores, acne, and blackheads. Although topical drug treatments can offer temporary relief, their prolonged usage may lead to side effects of dryness, irritation, or allergic reactions. Consequently, the development of safer and efficacious ingredients in cosmetics for managing sebum overproduction represents a significant yet challenging endeavor.

Current lifestyles include calorie-dense diets and late-night food intake, which can lead to circadian misalignment. Our group recently demonstrated that sweet treats before bedtime alter the clock system in healthy rats, increasing metabolic risk factors. Therefore, we aimed to assess the impact of the sweet treat consumption time on the clock system in rats fed a cafeteria diet (CAF).

The purpose of this article is to investigate the effects of walnut (Juglans regia L.) kernel pellicle on the composition and properties of enzymatic hydrolysis products of walnut meal using peptidomics and bioinformatics. In this study, a total of 3423 peptide sequences were identified in peeled walnut protein hydrolysates (PWPH) and unpeeled walnut protein hydrolysates (UWPH).

In this study, quinoa, which is a good alternative for celiacs, was tried to be used instead of flour by sprouting it and drying it in the airfryer. Flour obtained from quinoa seeds prevents spreading and hardens the product. It was predicted that this problem could be overcome by germination and drying in the airfryer.

Tea saponin has garnered tremendous interest for its potential use in surfactant and drug synthesis. This research was designed to develop a technique based on pH-responsive switchable deep eutectic solvents (SDESs) for extracting tea saponins from Camellia oleifera seed meal. SDES synthesized from hexanoic acid and triethanolamine (1:1 molar ratio) offered the optimum extractive performance and the optimal conditions were obtained through single-factor experiments: 30 wt% water content in SDES, solid-liquid ratio of 1:30 g/mL, 60°C extraction temperature, 30 min extraction time, and acid volume of 1500 µL.
