什么是麦芽糊精？
What is maltodextrin?
麦芽糊精 (maltodextrin) 是一种常见的食品填充料和增稠剂。各类淀粉（如玉米、大米、小麦）是它的生产原料。随后，它们在水、酶及酸性物质的作用下被糊化、部分水解，更终通过喷雾干燥制成，呈白色粉末状。
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.
麦芽糊精粘性高，能较好地将食物中不同成分“绑定”在一起，增加食品稳定性。麦芽糊精也能作为防腐剂，延长食品保质期。
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.
哪些食物中有麦芽糊精？
Which foods have maltodextrin?
由于便宜、功能多样，绝大多数食品和饮品中都有麦芽糊精的身影，例如各式饼干、冰淇淋、蛋糕、沙拉酱、乳清蛋白粉、人工甜味剂、运动饮料、固体饮料、火腿等加工肉类、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.
部分婴幼儿有乳糖不耐受的情况，因此，市面上也有用麦芽糊精替代乳糖的奶粉，满足这部分婴幼儿的糖份和热量需求。
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.
吃下麦芽糊精后会怎样？
What happens after eating maltodextrin?
麦芽糊精在体内的“消化路线”和淀粉类食品一样，更终会被消化、分解为葡萄糖，为人体提供热量。
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，麦芽糊精的吸收速度和葡萄糖差不多，因此也属于升糖指数高，也就是吃下后能快速提升血糖的类别。但考虑到实际摄入量与其它提升血糖的食物相比不算大，因此对血糖浓度的整体影响偏小。
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.
