| Juglans regia L belonged to the plant of walnut department of walnut department,produces originally southeast European,East Asian and the North America area,is the humanity plants the most ancient tree to live one of nuts.The walnut other name walnut,the walnut,it with the almond,the cashew, the hazel juxtaposes for the world four big dry fruit,Is broad in our country distributed scope,In walnut kernel's main nutrition ingredient fat and the protein,the walnut economic value is very high.This article studied "the Yuan abundant" as experimented the material take the walnut early solid class group clone variety,studied the different packing separately (transparent polyethylene bag seal packing,aluminum foil seal packing,black plastic bag bulk) has processed and stores the condition differently(temperature) to in walnut kernel's peroxide value,the acid value as well as the walnut the related enzyme(SOD,CAT,lipase) the active change to the walnut kernel quality influence between,as well as turned rancid the relations with the oxidation.The test result indicated that,ln stores in the process, walnut kernel own oxidation resistance material for example: SOD,CAT and the walnut kernel oxidation turns rancid between the target acid value assumes the inverse correlation,also the normal temperature evades the light,the oxygen exclusion or the two union way as well as the low temperature stores,air regulation storage may maintain the high enzyme activity,the extension walnut storage period,studies the walnut kernel to store the relations thoroughly which if in the process the related oxidation resistance material change oxidizes turns rancid,this is helpful in us understood its oxidation turns rancid the mechanism,carries on before the processing,the sale for the walnut kernel stores massively provides the theoretically basis. |
