温度对水晶蜜柚和三红柚贮藏品质的影响OA

To explore the effect of temperature on the storage quality of Shuijing honey pomelo and Sanhong pomelo,and determine the suitable storage temperature for the two pomelo varieties.Shuijing Honey Pomelo and Sanhong Pomelo were stored at 25℃(room temperature warehouse),10℃,and 5℃(cold storage),and the fruit appearance color,weight loss rate,edible rate,soluble solids(TSS),and titratable acid(TA)were measured every 15 days.The results showed that the juice sac granulation and peel yellowing time of Shuijing honey pomelo stored at 25℃were the earliest,and the weight loss rate and edible rate were the highest,followed by those stored at 10℃;the juice sac granulation and peel yellowing time of fruits stored at 5℃were the latest,and the weight loss rate and edible rate were the lowest.In the late storage period,the TSS and TA in the pedicle,equatorial,and navel parts of Shuijing honey pomelo and Sanhong pomelo stored at 5℃were the highest,while the TSS and TA of Shuijing honey pomelo and Sanhong pomelo stored at 25℃and 10℃were lower.The juice sac granula-tion time of Sanhong pomelo was earlier than that of Shuijing honey pomelo,but the peel yellowing and fruit TA decrease were slower.In summary,low temperature can better maintain the storage quality of Shuijing Honey Pomelo and Sanhong Pomelo,among which the fruit quality stored at 5℃is the most stable.
