Walnut is a worldly accepted functional health food. It is widely scattered in our land. With fat and protein as its main nutrition, walnut gets its high economic value. This program, by packing in vacuum or not, we will find out how the activation change of protein, fat, peroxide and acid value as well as some enzyme related activation( eg. Lipase, Peroxidase, polyphenol oxidase ect.) effect on its quality in proper storing conditions. So as to the relations among its oxidative rancidity, and how much will the storing condition affect on the quality, oxidative rancidity time and extent is closely related to the storing condition. Thus we come to an conclusion that热心网友 时间:2024-11-30 02:00
Walnut is an functional nutritious food acknowledged by the world, it is widely planted in china. The main nutrition in walnut is fat and protein, it has high value in economy. This project states the processing of package in natural and vaccum; the change of protein, fat, peroxide value, acid value and Relevant enzyme(Lipase, peroxidase, polyphenol oxidase, etc) activity on walnut quality influence under proper storage condition; as well as relationship in Oxidative rancidity. Storage condition has a great influence on walnut quality, timing and and degree of Oxidative rancidity are closely related to storage condition. Vaccum is good for walnut storage.热心网友 时间:2024-11-30 02:00
Walnut is the world recognized as functional food. In our country are widely distributed, walnut main nutrients is fat and protein walnut economic value is very high. This project based on the nature of the walnut and vacuum state packaging processing, in the appropriate storage condition, to the walnut protein, fat, peroxide value, acid value and walnut in the enzyme (lipase, peroxidase, polyphenol oxidase, etc.) of the active changes on the quality of walnut, and the effect of the relationship between the oxidation rancid. Storage conditions on the quality of the walnut has a great influence, oxidative rancidity of time and degree and storage conditions, vacuum is closely related to walnut storage热心网友 时间:2024-11-30 02:01
