Test 2: Effect on soluble solids content of strawberries:
The results showed that the soluble solids content of chitosan oligosaccharide treatment and the fruit of the control group showed a downward trend during storage. The soluble solids content and decrease levels of chitosan oligosaccharide-treated fruits were higher than those in the control group, indicating that chitosan oligosaccharides could inhibit the consumption of sugar during strawberry storage and ensure the flavor quality of fruits.
During the whole storage period, the soluble solids content of strawberry fruits in the chitosan oligosaccharide treatment group with a mass fraction of 1.5% was higher than that in other treatment groups and control groups, indicating that 1.5% was the most suitable mass fraction for controlling the reduction of soluble solids content in strawberry fruits.
Test 3: Effect on the content of titratable acid in strawberries:
The experimental results showed that the titratable acid content in the fruit gradually decreased during the harvesting and storage of strawberries, while the three concentrations of chitosan oligosaccharide treatment showed a certain inhibitory effect on the consumption of titratable acid in strawberry fruit, and this inhibitory effect was obvious in the 1.5% chitosan oligosaccharide treatment group, but the difference between the treatment group was not significant.
