淀粉为什么不属于农产品？

中文版

淀粉是一种多糖类碳水化合物，是由多个葡萄糖分子通过糖苷键连接而成的高分子化合物。虽然淀粉广泛存在于许多植物中，但它本身并不属于农产品。

农产品通常指的是直接从农田、果园、牧场等生产地收获的未经过加工的原始食材，如谷物、蔬菜、水果、肉类等。而淀粉则是这些农产品经过加工处理后的产物。在农业生产中，谷物、根茎类蔬菜等植物中含有淀粉，但这些植物本身并不是淀粉，而是淀粉的来源。

淀粉在食品、医药、化工等领域有广泛的应用。它可以通过加工农产品得到，例如通过磨碎谷物或根茎类蔬菜，然后用水浸泡、沉淀、干燥等工艺提取淀粉。因此，虽然淀粉与农产品有密切关系，但它本身并不属于农产品，而是农产品的加工产品。

Why Starch Is Not Considered an Agricultural Product?

Starch is a type of polysaccharide carbohydrate, a high-molecular-weight compound consisting of multiple glucose molecules linked together by glycosidic bonds. Although starch is widely found in many plants, it itself does not belong to agricultural products.

Agricultural products typically refer to unprocessed raw ingredients harvested directly from production areas such as farmland, orchards, and pastures, such as grains, vegetables, fruits, and meats. In contrast, starch is a product resulting from the processing of these agricultural products. While plants like grains and root vegetables contain starch, these plants themselves are not starch but are rather the source of starch.

Starch has a wide range of applications in the food, pharmaceutical, and chemical industries. It can be obtained by processing agricultural products, such as grinding grains or root vegetables and then extracting the starch through processes like soaking in water, sedimentation, and drying. Therefore, while starch has a close relationship with agricultural products, it does not belong to agricultural products itself but is instead a processed product derived from them.
