![]() Results from the anti-hydrogen peroxide and methyl viologen stress experiment showed that AAPsl could significantly prolong the life of worms under oxidative stress compared to the negative control group (P < 0.05). High AAP recovery rates and strong free radical scavenging rates of 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt and 1,1-dibenzoyl-2-trinitrophenylhydrazine were obtained by 30% ethanol (AAPs1). AAP yield reached 13.91% ± 0.95% at a temperature of 7☌, liquid-to-material ratio of 75 mL/g, and extraction time of 70 min. auricula-judae powder, and time had the most obvious effects. auricula-judae powder, enzyme usage, time, pH, etc.), temperature, ratio of liquid-to-A. The results showed that among the factors affecting AAP yield (temperature, liquid-to-A. Auricularia Auricula-Judae: Benefits & Identification of Wood Ear Mushroom. Optimal fractions with a high polysaccharide recovery rate and a strong free radical scavenging rate were obtained, and their antioxidant stress effect was studied using Caenorhabditis elegans as the model organism. Auricularia auricula is a popular edible mushroom in East Asia, especially in China, Japan, and Korea (Nguyen, Chen, et al., 2012 Skara, Kalisz, Grabowska, Kalisz, Grabowska, & Siwulski, 2015 ). ![]() ![]() Chinese people also believed that if this mushroom is eaten regularly or brewed in a tea, enhance health and treat ailments 4. Four ethanol concentrations (30%, 50%, 70%, and 90%) were used to grade AAPs. polytricha have been used in Chinese folk medicines for thousands of years and has traditionally been used to treat hemorrhoids and as a stomach tonic 3. It has a purplish-grayish brown to dingy brown color, is smooth and wrinkled in the center, and has fine hairs. Response surface methodology with a Box-Behnken design was used to investigate the effects of a neutral protease on Auricularia auricula-judae polysaccharide (AAP) extraction yield. Auricularia auricula-judae (English: Jews ear, Black wood ear) is a common mushroom that grows mainly on woods. Wood Ear Mushroom, scientific name Auricularia auricula-judae, is a type of edible jelly mushroom with an ear-shaped form that grows on trees, especially elder trees.
