The preservation effect of Modified-atmosphere fresh-keeping technology in refrigerator on the nutrition and flavor of fruits
The research investigates the nutrition and flavor changes of fruits during storage in Modified-atmosphere fresh-keeping space and ordinary refrigerated drawers in refrigerators through comparative experiments.The refrigerator with Modified-atmosphere fresh-keeping function has significant preservation advantages in reducing the respiration rate of fruits and delaying the loss of nutrients from ingredients.Through testing the soluble sugar,vitamin C,anthocyanin content,and flavor of fruits.Under the condition of 4℃,the total volatile flavor component content of Hami melon stored in Modified-atmosphere fresh-keeping space for 7 days is 14.8ug/g,while in ordinary refrigerated drawers conditions,the total volatile flavor component content of Hami melon stored for 7 days is 11.2ug/g.Moreover,the Modified-atmosphere refrigeration preservation environment has a certain effect on maintaining unique flavors.The research results provide data reference and technical guidance for subsequent research on refrigerator c Modified-atmosphere fresh-keeping technology.
