Abstract:

The effects of a composite biological antisaling agent mainly formulated with chitosan, pollen polysaccharide and
tea polyphenol on the storage quality of fresh corn were investigated by moisture content, weight loss rate, hardness, odor
and sensory quality as a function of storage time. The results showed that the loss of moisture content in fresh corn subjected to
pretreatment with the antisaling agent and subsequent cold storage for 30 days was reduced by 18.6% as compared with that of the
control. Meanwhile, the weight loss rate of fresh corn was decreased by 19.9% and the hardness was lowered by 42.68 N. However,
there were only slight changes in odor and sensory qualities were well maintained. The biological antisaling agent could effectively
inhibit the loss of moisture content, decrease the nutrient losses, reduce the weight loss rate, and maintain the elasticity of fresh corn
while significantly preserving sensory qualities such as color, shape, odor and taste. Therefore, the biological antisaling agent had
significant preservation effects on fresh corn.

Key words: fresh corn, biological antisaling agent, storage quality
