Why do yogurt need thickener

Introduction: yoghurt is fermented from pure milk, not only contains rich nutrition, but also contains lactobacillus to help digestion, which is conducive to the absorption of calcium and phosphorus Why should yogurt be thickened? Is it safe to add thickener to food? Let's talk about it Yogurt as a food has a history of at least 4500 years The earliest yogurt may be that the milk of the nomadic people in the sheepskin bag is naturally fermented by the bacteria attached to the bag and becomes cheese Now, although many countries claim that yogurt is their own invention, so far there is no strong evidence to show who is the first discoverer, maybe yogurt has been found many times independently Yoghurt is a kind of dairy product which is made from fresh whole milk and fermented by Lactobacillus Raw milk must be fresh milk without antibiotics, preservatives, fat content not less than 3%, non fat dry matter greater than 8.5%, acidity less than 0.16% The amount of added sugar is generally controlled between 5% and 10% Sterilization add the weighed fresh milk in proportion to the top-grade white sugar and boil for 3min, then filter Cool down and inoculate the boiled and filtered milk to 38-42 ℃ and then add the lactic acid bacteria Fermentation, cooling and sampling inspection of finished products after the introduction of lactic acid bacteria, fresh milk is bottled and sealed in time for 4-6 hours at 36-38 ℃ In the later stage of fermentation, the acidity and solidification of semi-finished products were checked at any time, and the best acidity was 0.58 After checking and confirming that the acidity and coagulation meet the requirements, the fermentation can be stopped Take it out carefully, cool it naturally in the room to room temperature first, and then transfer it to the refrigerator at 2-6 ℃ for cooling, which can prevent excessive fermentation and help the yogurt solidify Why do you put thickeners in yogurt? The purpose of using thickeners in yogurt is to reduce the content of fat and get a proper taste Because the taste of yoghurt is closely related to the fat content in it For various reasons, people tend to reduce the fat in dairy products, or even simply eat "fat free dairy products" The yoghurt formed is not like yoghurt, and the taste will become worse In order to change the taste of yogurt, people will add some food gums, the most commonly used thickeners are modified starch, gelatin, pectin and so on Make yogurt "sticky" enough to become a normal semi-solid, which can also simulate the taste of fat to a certain extent And thickener and human body have a lot of benefits, so, yogurt to put thickener Is it safe to add thickeners to food?
