Abstract: This text has studied the antistaling agent Amistai Dip under normal atmospheric temperature terms, density with membrane to the HaMi Melon quality influence after adopting in the Modified atmosphere storage technology. Through breathing the speed in preserving the HaMi Melon vitamin C content, candy sour content, etc. every physiological survey of index is it probe into the antistaling agent physiology influence to the HaMi Melon aging course to come, prove it keep fresh quality of the result. Use the antistaling agent Amistai Dip, and pack with PE plastic wrap from behind the preservation of 30 days, preserving the result indicates: Amistai Dip can suppress breathing of the HaMi Melon ,candy,sour,vitamin C a lengthening the life-span of the HaMi muskmelon, it is old and feeble to delay it,keep up quality of HaMi Melon after adopting.
