When I go to the supermarket now, I am quite calm. When I want to buy something, I will pick it up and look at the ingredients. If there are too many additives, I will put them down. Of course, there are so few things without additives at all that I once bought snacks in the supermarket and only took a bag of crispy rice. . . Think about whether I have obsessive-compulsive disorder!
Ok, back to today's topic, a pig received a yogurt machine as a gift on Teacher's Day. I thought it would be cheaper and more hygienic to make my own yogurt (in fact, I just wanted to try the yogurt machine), so I planned to make my own yogurt. The instructions say that I want milk and starter or pure yogurt as raw materials. I don't know what an appetizer is. Thinking that pure yogurt should be easy to buy, I plan to go to the supermarket to buy pure yogurt the next day.
When I went to the supermarket, boy, all yogurts were called probiotics or Guan Yi milk, and there were more than n kinds of ingredients. I haven't found pure yogurt for a long time. Finally, I found that there are only two kinds of fresh oriental yogurt besides milk and sugar, so I decided to take it. As for the result, let's talk about it next time. .
Say so much about food additives. The names are so long that I don't know what they mean. Now I'll show you one by one. Surprisingly, almost all the ingredients are the same: raw milk, white sugar, high fructose corn syrup, food additives (acetylated starch phosphate, hydroxypropyl starch phosphate, gelatin, acesulfame K), probiotics (Streptococcus thermophilus, Lactobacillus bulgaricus) and food essence.
High fructose corn syrup is starch sugar crystal made from plant starch by hydrolysis and isomerization, and it is an important sweetener. The production of high fructose corn syrup is not limited by region and season, with relatively simple equipment and low investment cost. Because its components are mainly fructose and glucose; Therefore, it is called "high fructose syrup". Seems harmless.
Acetylated starch phosphate, to put it bluntly, is thickener, stabilizer and coagulant.
Hydroxypropyl starch phosphate is also a thickener, so two thickeners are needed to make a bottle of yogurt? !
Gelatin is usually used to make jellies and other desserts. It is made of cooked animal bones, skins and tendons. Another option is agar made of seaweed; Another substitute is made from pueraria lobata. Agar sold generally has noodle-like strips, powders, long blocks, and is often grayish white. If it is really an animal bone or something, it shouldn't hurt.
Acesulfame K is considered as one of the most promising sweeteners because of its simple production process, low price and better performance than aspartame. After 15 years of experiments and tests, the United Nations World Health Organization, the US Food and Drug Administration, the European Union and other authoritative organizations have come to the conclusion that "Acesulfame K is safe and harmless to people and animals". Acesulfame K is a synthetic sweetener. Regular consumption of foods containing excessive synthetic sweeteners will do harm to the liver and nervous system, especially to the elderly, pregnant women and children. If eaten in large quantities in a short time, it will cause thrombocytopenia and lead to acute massive bleeding. It's terrible.
Streptococcus thermophilus is considered as a "GRAS" ingredient, which is widely used to produce some important fermented dairy products, including yogurt and cheese (such as Swiss and Limburg cheese). Streptococcus thermophilus also has some functional activities, such as producing extracellular polysaccharide, bacteriocin and vitamins. In addition, Streptococcus thermophilus can also be used as a potential beneficial bacteria. Experiments show that it has health care function, transport activity and certain gastrointestinal adhesion. Therefore, we need to explore the ability of different Streptococcus thermophilus to produce different metabolites, not just the amount of lactic acid produced by their fermentation.
Lactobacillus bulgaricus and Streptococcus thermophilus are essential ingredients for making yogurt, even if they are beneficial to human body!
A food additive is prepared from various edible spices and allowable additives, and is used for flavoring food. Additives include carriers, solvents and additives. The carrier includes sucrose, dextrin, gum Arabic, etc. The flavor blending creation of edible essence mainly imitates the flavor and taste of natural fruits and foods, and pays attention to the simulation of flavor and taste. Not so good.
Look at how much food we eat, which is good for the human body and which is bad, and we will know for ourselves. I will find other additives in the future, so I still cook by myself. What I make by myself is the most reassuring.
