2、藏品質(zhì)更優(yōu);水分含量25-3%的花生不適合采用密閉性包裝。研究發(fā)現(xiàn),水分含量在安全水分內(nèi)的花生適合用高阻隔性材料包裝;對于水分含量略高于安全水分的花生,適合用低氣密性的包裝材料;對于較高水分的花生,則不適合用密閉性包裝方法包裝。關(guān)鍵詞:水分,花生,包裝材料,貯藏,過氧化值,酸價(jià)EffectofpackagingmaterialsonstoragepropertyofdifferentmoisturecontentpeanutL]NYong—gan,F(xiàn)UXiao—ji,ZHOUJin—ying,PANRun—tian,F(xiàn)ENGJian—xiong',(1.CollegeofFo
