麦芽糊精是什么
What is maltodextrin
麦芽糊精是指以淀粉或淀粉质（如玉米、大米、小麦等）为原料，以酶法低度水解、精制、喷雾干燥制成的不含淀粉的淀粉衍生物。即麦芽糊精为经过预糊化后的淀粉，是淀粉的水解产物。
Maltodextrin is a starchy starch derivative made from starch or starch, such as corn, rice, wheat, etc., which is made by enzymatic hydrolysis, refining and spray drying. Maltodextrin is the starch after pre gelatinization, which is the hydrolysate of starch.
麦芽糊精是一种常见的食品填充料和增稠剂，因为具备无异味，即使在浓厚状态使用，也不会掩盖其他原料的风味和香味、有适当的粘性，吸湿性小，不结团，溶解性强，具有很好的乳化作用和增稠作用和易被人体消化吸收，适宜作为病人和婴幼儿食品的基础原料的特点而被广泛应用在食品中。
Maltodextrin is a common food filler and thickener, because it has no peculiar smell, even when it is used in a strong state, it will not cover up the flavor and fragrance of other raw materials, has appropriate viscosity, has little hygroscopicity, does not agglomerate, has strong solubility, has good emulsification and thickening effect, and is easy to be digested and absorbed by human body, so it is suitable to be the basic raw material for patients and infants It is widely used in food.
麦芽糊精在奶粉营养成分中究竟扮演着什么角色？
What role does maltodextrin play in milk powder nutrition?
①，麦芽糊精属于碳水化合物，可提供能量。
Firstly, maltodextrin belongs to carbohydrate and can provide energy.
②麦芽糊精具有较强的增稠和填充效果，添加在奶粉中可使奶粉体积膨胀不易结团，速溶易冲调同时降低成本。
② maltodextrin has a strong thickening and filling effect. Adding maltodextrin to milk powder can make the milk powder bulky and not easy to agglomerate, instant and easy to prepare and reduce the cost.
③玉米糖浆和麦芽糊精相似，也是一种没有味道的营养性多糖，都具有许多如水溶性好、耐熬煮以及易于人体吸收等独特的理化性能。
③ corn syrup, similar to maltodextrin, is also a kind of nutritious polysaccharide without taste. It has many unique physical and chemical properties, such as good water solubility, boiling resistance and easy absorption by human body.
为什么大家会对麦芽糊精谈之色变？
Why do you talk about the color change of maltodextrin?
主要是因为对于小婴儿来说，麦芽糊精不是更佳的碳水化合物来源，升糖指数高且低廉其营养价值低于乳糖。
The main reason is that maltodextrin is not the best source of carbohydrate for infants, and its nutritional value is lower than that of lactose because of its high glycemic index and low price.
麦芽糊精添加到婴幼儿配方奶粉中，主要是为了让奶粉不易结团，易冲调，同时也做为碳水化合物的来源之一给宝宝提供能量。
Maltodextrin added to infant formula is mainly to make milk powder not easy to agglomerate, easy to mix, but also as a source of carbohydrates to provide energy for the baby.
麦芽糊精无害，但不能过量添加
Maltodextrin is harmless, but not excessive
婴儿配方食品标准中未明确规定麦芽糊精的添加量，但规定在配方奶粉中提供碳水化合物的成分为乳糖、乳糖和葡萄糖聚合物，只有经过预糊化后的淀粉才可以加入到婴儿配方食品中，不得使用果糖。对于0-6个月的宝宝来说，乳糖是其公认的更佳碳水化合物来源，因其碳链短，一分子乳糖可分解为一分子葡萄糖和一分子半乳糖，半乳糖能促进脑苷脂类和黏多糖类的生成，对婴幼儿智力发育非常重要，故标准规定婴儿配方食品（0~6月龄）中乳糖占碳水化合物的总量要≥90%，其余被允许添加的碳水化合物在总量的10%以内都是可以的。
The national standard for infant formula does not specify the addition amount of maltodextrin, but it stipulates that the preferred components of carbohydrates provided in the formula are lactose, lactose and glucose polymer. Only starch after pre gelatinization can be added to infant formula, and fructose is not allowed. For babies aged 0-6 months, lactose is recognized as the best carbohydrate source. Because of its short carbon chain, one molecule of lactose can be decomposed into one molecule of glucose and one molecule of galactose. Galactose can promote the formation of cerebroside lipids and mucopolysaccharides, which is not always important for the intellectual development of infants. Therefore, the national standard stipulates that lactose accounts for carbohydrate in infant formula （0-6 months old） The total amount of carbohydrates should be no less than 90%, and the rest of carbohydrates allowed to be added should be within 10% of the total amount.
