麥芽糊精是什么
What is maltodextrin
麥芽糊精是指以淀粉或淀粉質(zhì)（如玉米、大米、小麥等）為原料，以酶法低度水解、精制、噴霧干燥制成的不含淀粉的淀粉衍生物。即麥芽糊精為經(jīng)過預(yù)糊化后的淀粉，是淀粉的水解產(chǎn)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.
麥芽糊精是一種常見的食品填充料和增稠劑，因為具備無異味，即使在濃厚狀態(tài)使用，也不會掩蓋其他原料的風(fēng)味和香味、有適當(dāng)?shù)恼承?，吸濕性小，不結(jié)團(tuán)，溶解性強，具有很好的乳化作用和增稠作用和易被人體消化吸收，適宜作為病人和嬰幼兒食品的基礎(chǔ)原料的特點而被廣泛應(yīng)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.
麥芽糊精在奶粉營養(yǎng)成分中究竟扮演著什么角色？
What role does maltodextrin play in milk powder nutrition?
?、?，麥芽糊精屬于碳水化合物，可提供能量。
Firstly, maltodextrin belongs to carbohydrate and can provide energy.
②麥芽糊精具有較強的增稠和填充效果，添加在奶粉中可使奶粉體積膨脹不易結(jié)團(tuán)，速溶易沖調(diào)同時降低成本。
?、?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.
?、塾衩滋菨{和麥芽糊精相似，也是一種沒有味道的營養(yǎng)性多糖，都具有許多如水溶性好、耐熬煮以及易于人體吸收等獨特的理化性能。
?、?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.
為什么大家會對麥芽糊精談之色變？
Why do you talk about the color change of maltodextrin?
主要是因為對于小嬰兒來說，麥芽糊精不是更佳的碳水化合物來源，升糖指數(shù)高且低廉其營養(yǎng)價值低于乳糖。
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.
麥芽糊精添加到嬰幼兒配方奶粉中，主要是為了讓奶粉不易結(jié)團(tuán)，易沖調(diào)，同時也做為碳水化合物的來源之一給寶寶提供能量。
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.
麥芽糊精無害，但不能過量添加
Maltodextrin is harmless, but not excessive
嬰兒配方食品標(biāo)準(zhǔn)中未明確規(guī)定麥芽糊精的添加量，但規(guī)定在配方奶粉中提供碳水化合物的成分為乳糖、乳糖和葡萄糖聚合物，只有經(jīng)過預(yù)糊化后的淀粉才可以加入到嬰兒配方食品中，不得使用果糖。對于0-6個月的寶寶來說，乳糖是其公認(rèn)的更佳碳水化合物來源，因其碳鏈短，一分子乳糖可分解為一分子葡萄糖和一分子半乳糖，半乳糖能促進(jìn)腦苷脂類和黏多糖類的生成，對嬰幼兒智力發(fā)育非常重要，故標(biāo)準(zhǔn)規(guī)定嬰兒配方食品（0~6月齡）中乳糖占碳水化合物的總量要≥90%，其余被允許添加的碳水化合物在總量的10%以內(nèi)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.
