什么是麥芽糊精？
What is maltodextrin?
麥芽糊精 (maltodextrin) 是一種常見的食品填充料和增稠劑。各類淀粉（如玉米、大米、小麥）是它的生產(chǎn)原料。隨后，它們?cè)谒?、酶及酸性物質(zhì)的作用下被糊化、部分水解，更終通過噴霧干燥制成，呈白色粉末狀。
Maltodextrin is a common food filler and thickener. All kinds of starch (such as corn, rice, wheat) are the raw materials for its production. Subsequently, they were gelatinized and partially hydrolyzed under the action of water, enzyme and acidic substances. They were finally made by spray drying and showed white powder.
麥芽糊精粘性高，能較好地將食物中不同成分“綁定”在一起，增加食品穩(wěn)定性。麥芽糊精也能作為防腐劑，延長食品保質(zhì)期。
Maltodextrin has high viscosity, which can bind different components in food together and increase food stability. Maltodextrin can also be used as a preservative to extend the shelf life of food.
哪些食物中有麥芽糊精？
Which foods have maltodextrin?
由于便宜、功能多樣，絕大多數(shù)食品和飲品中都有麥芽糊精的身影，例如各式餅干、冰淇淋、蛋糕、沙拉醬、乳清蛋白粉、人工甜味劑、運(yùn)動(dòng)飲料、固體飲料、火腿等加工肉類、低脂食品和保健品中。
Due to its low price and various functions, maltodextrin can be found in most foods and drinks, such as biscuits, ice cream, cakes, salad dressing, whey protein powder, artificial sweeteners, sports drinks, solid drinks, ham and other processed meat, low-fat food and health products.
部分嬰幼兒有乳糖不耐受的情況，因此，市面上也有用麥芽糊精替代乳糖的奶粉，滿足這部分嬰幼兒的糖份和熱量需求。
Some infants and young children have lactose intolerance. Therefore, maltodextrin milk powder can be used to replace lactose in the market to meet the sugar and caloric requirements of these infants.
吃下麥芽糊精后會(huì)怎樣？
What happens after eating maltodextrin?
麥芽糊精在體內(nèi)的“消化路線”和淀粉類食品一樣，更終會(huì)被消化、分解為葡萄糖，為人體提供熱量。
Maltodextrin in the body "digestion route" and starch food, will eventually be digested, decomposed into glucose, for the human body to provide heat.
研究指出，麥芽糊精的吸收速度和葡萄糖差不多，因此也屬于升糖指數(shù)高，也就是吃下后能快速提升血糖的類別。但考慮到實(shí)際攝入量與其它提升血糖的食物相比不算大，因此對(duì)血糖濃度的整體影響偏小。
Studies have pointed out that maltodextrin has the same absorption rate as glucose, so it belongs to the category of high glycemic index, that is, it can quickly improve blood glucose after eating. However, considering that the actual intake is not large compared with other food to improve blood glucose, the overall impact on blood glucose concentration is relatively small.
