Article Abstract
Silkworm pupae, a waste product from the silk production industry, can be an alternative source of edible oil, thus reducing the industry's waste. In the present work, frozen silkworm pupae were used as raw material to extract oil via an aqueous saline process. The Box-Behnken design (BBD) and response surface methodology (RSM) were used to optimize the extraction process. The extraction conditions with the highest oil yield and a low peroxide value were obtained when using a saline solution concentration of 1.7% /, a ratio of aqueous liquid to silkworm pupae of 3.3 mL/g, and a 119 min stirring time at the stirring speed of 100 rpm. Under these conditions, silkworm oil with a yield of 3.32%, peroxide values of approximately 1.55 mM, and an acid value of 0.67 mg KOH/g oil was obtained. The extracted oil contained omega-3 acids (α-linolenic acid), which constituted around 25% of the total fatty acids, with approximate cholesterol levels of 109 mg/100 g oil. The amounts of β-carotene and α-tocopherol were approximately 785 and 9434 μg/100 g oil, respectively. Overall, the results demonstrated that oil extracted from silkworm pupae has good quality parameters and thus can be used as a new valuable source of edible lipids.
This study among moderately fit male athletes investigated changes in oxidative stress and antioxidant levels after supplementation with Eri silkworm cornflakes. Male university athletes ( = 18, age 19-21 years) were enrolled in a randomized crossover trial. They participated in either the supplementation period (consuming 0.
Despite the increasing importance of the condition of post-stroke cognitive impairment (PSCI), the current therapy efficacy is limited. Since oxidative stress and inflammation are targeted in anti-stroke therapy, we aimed to assess the protective effect against PSI of an orodispersible film loaded with silkworm pupae hydrolysate and a combined extract of holy basil and ginger (JP1), which show antioxidant, and anti-inflammation effects. Male Wistar rats (200-250 g) were administered JP1 at doses of 1, 10, and 100 mg/kg BW 45 min before a 6 h immobilization stress exposure for 14 days.

Background: Ecdysone-induced protein 93 F (E93, also known as Eip93F) plays a crucial role in the reproductive process of numerous insects. This study aims to delineate the function of E93 in Chilo suppressalis and elucidated the regulatory mechanism by which E93 influences the reproduction of C. suppressalis METHODS AND RESULTS: The results of the bioinformatics analysis indicate that C.
* The review assesses the effects of insect meal on ruminal fermentation, digestibility, and overall animal performance, using a limited dataset for analysis, suggesting no negative impacts on these factors when insects partially replace protein sources.
* Notably, the Oriental Hornet was found to enhance growth and digestion in ruminants, while it is recommended that insect inclusion in diets should not exceed 30% to maintain optimal fermentation processes.
