Abstract
This experiment was conducted to study different pretreatments on physical-chemical properties and quality of Fraiar and Nai plum,and also to make correlation analysis between firmness and pectin contents of plums.The results showed that in 42 days storage time,chitosan coating and calcium treatment at 2 ℃ could delay the decrease of titratable acidity and firmness,the increase of total soluble solids mass fraction,and inhibit the degradation of cell wall polysaccharide(water soluble pectin,chelate-soluble pectin,sodium carbonate-soluble pectin,hemi cellulose and cellulose) better than other treatments,such as storage at 2 ℃ intermittent warming,2 ℃ calcium treatment,storage at 2 ℃ and storage at 8 ℃.Generally,chitosan coating and calcium treatment at 2 ℃ can keep the texture characteristics of plum fruit better in 42 days storage,the results can provide theoretical basis and technical method for plum storage.
