中文摘要:

      近年来我国鲜食玉米产业发展迅猛, 但同时也暴露出诸多产业乱象。梳理现有鲜食玉米标准体系是促进产业标准化、规范化的重要举措。本文通过对我国现行鲜食玉米标准进行梳理, 总结出目前我国鲜食玉米标准体系中抽样及一般性检测标准较完善、技术规程体系成熟、标准体系框架已建立的特点; 同时提出我国鲜食玉米标准体系存在技术规程标准内容重复、品质分级标准混乱、缺乏营养评价指标相关标准、感官评价标准混乱、缺乏甜糯玉米和笋玉米的相关标准、标准体系结构不合理等的问题; 并针对上述问题提出对应应统一技术规程标准, 建立营养评价体系, 统一品质分级标准, 统一感官评价指标, 完善甜糯玉米和笋玉米相关标准的解决办法。为鲜食玉米标准体系的建设及规范化提供参考和建议。

英文摘要:

      In recent years, the fresh corn industry in China has developed rapidly, but at the same time it has exposed many industrial chaos. Sorting out the existing fresh corn standard system is an important measure to promote industrial standardization and standardization. This article combined the current fresh corn standards of fresh food in my country, and summarized the characteristics of sampling and general testing standards in the current fresh corn standard system, mature technical regulations and systems, and the establishment of the standard system framework; at the same time, it proposed there were still many unreasonable problems in the standards, such as the duplication of the content of technological standards, the confusion of the classification of quality and sensory evaluation, the scarcity of standards for nutrition evaluation, the dearth of identification standards for sweet-waxy and baby corn, and the inappropriate structure of the standard system. In view of the above problems, the corresponding solutions were proposed to unify the technical regulations and standards, establish the nutrition evaluation system, unify the quality grading standards, unify the sensory evaluation indexes, and improve the related standards of sweet glutinous corn and bamboo shoot corn, so as to provide references and suggestions for the construction and standardization of fresh corn standard system.
