采收期结合精准控温对维纳斯黄金苹果贮藏品质和防褐保鲜的效应
Effect of Harvest Period Combined with Precise Temperature Control on Storage Quality and Browning Prevention of Venus Gold Apple Fruits
摘要
Abstract
To clarify the optimal harvesting period and storage temperature for the Venus apple fruit used for storage.The effects of three harvesting periods combined with three precise storage temperatures on fruit quality,anti-browning and preservation of Venus gold apple during 20℃shelf life after cold storage were studied.The re-sults showed that harvesting period Ⅰ(relatively early harvest)combined with storage at-1.5℃(relatively low temperature)could maintain high fruit firmness,but the soluble solid content(SSC)of fruit was low,the taste and flavor of fruit were poor,and different degrees of browning of skin,heart and flesh appeared during shelf life.When harvested at period Ⅲ(relatively late),stored at 3℃(relatively high temperature)until January 20,the fruit had high SSC,good taste and flavor.However,when stored at 20℃for 24 h and stored on the shelf for 7 days,the fruit flesh was spongy and severely browning.The results showed that compared with-1.5 and 3.0℃,0℃maintained higher firmness,SSC,titratable acid(TA)and ascorbic acid contents,and better main-tained fruit chlorophyll fluorescence activity,and delayed fruit senescence.For the same storage temperature,the contents of TA and ascorbic acid in the fruits of harvest periodⅡwere higher than those of harvest periodⅠandⅢ.The comprehensive analysis showed that the harvest period Ⅱ and Ⅲ combined with 0,3℃could maintain the good merchantability and intrinsic quality of Venus gold apple stored in the medium and short term.For the Ve-nus gold apple with medium and long-term storage,the harvest period Ⅱcombined with 0℃accurate temperature storage could not only effectively inhibit fruit browning,slow fruit softening and senescence,but also maintain good flavor and quality of fruit during shelf life.关键词
