摘要/Abstract

摘要：

采用壳聚糖、花粉多糖、茶多酚为主配制的复合生物保鲜剂对鲜食玉米进行保鲜，测定含水量、质量损失率、硬度、气味与感官品质，研究贮藏期间鲜食玉米的品质变化。结果表明，与对照相比，冷藏条件下经保鲜剂处理的鲜食玉米贮藏30 d时含水量减少损失18.6%，质量损失率降低19.9%，硬度降低42.68 N，气味变化较小，感官品质良好。生物保鲜剂可有效抑制鲜食玉米水分散失，减少营养成分损失，降低质量损失率，保持籽粒弹性；还可保持鲜食玉米的色泽、形态、气味、滋味等感官品质，因此，生物保鲜剂对鲜食玉米的保鲜效果显著。

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
