摘要: Summary Sericin, a water-soluble globular protein derived from silk industry wastewater, was investigated for food industrial applications. The results proved that sericin retarded polyphenol oxidase (PPO) activity. However, the degree of inhibition varied depending on enzyme origins, types substrate, content and molecular size. Using catechol as under conditions studied, lowered purified mushroom PPO apple extract activity by 40% mango 75%. Kinetic studies indicated type dependent substrates used. Inhibitory effects increased increased. reduction in size enzymatic hydrolysis produced hydrolysate with ability to decrease approximately three times greater than sericin. Fresh-cut Red Delicious apples coated showed significant weight loss improvement colour texture.
