Effect of Different Storage Temperatures on the Storage Quality of Sweet-Waxy Maize
In order to explore the effects of different storage temperatures on the storage quality of sweet waxy maize,the effects of storage at 20,4 and 0 ℃ on its appearance quality,hardness,starch and sugar content were studied.The results showed that,compared with the three storage temperatures,low temperature significantly main-tained the appearance quality,color and hardness of sweet waxy maize,and 0 ℃ had the best preservation effect.Sweetness reduction is a key indicator of postharvest quality deterioration in fresh maize.Storage at 4 ℃ and 0 ℃can delay the decrease of soluble solids,soluble sugars,soluble sugar components and other sugars and increase the starch content,promote the accumulation of non-starch polysaccharides and maltose,and maintain the high sweet-ness of fresh maize.Compared with storage at 4 ℃ and 0 ℃,0 ℃ was the most effective in preserving the sugar con-tent,hardness,and sensory quality of fresh sweet-waxy maize.
