Starch is a nutrient stored in the plant body, and it should not be contained in pork, so you can add it when stir-frying pork!
Starch is also known as starch in the catering industry, is a polymer of glucose, the general formula is [(C6H10O5)N], hydrolysis to the disaccharide stage is maltose, the chemical formula is (C12H22O11), and the glucose is obtained after complete hydrolysis, and the chemical formula is (C6H12O6). There are two types of starches: amylose and amylopectin. Amylose contains hundreds of glucose units, and amylopectin contains thousands of glucose units.
Among the natural starches, the amylose accounts for about 22 26, it is soluble, and the rest is amylopectin. When tested with an iodine solution, the amylose solution appears blue, while amylopectin turns reddish-brown when it comes into contact with iodine. (The reason is:.)
Amylose with long helix segments can form complexes with long-chain poly-I3 and produce a blue color. Amylose iodine complex contains 19 levels of iodine. Amylopectin is compounded with iodine to produce reddish purplish-red red because the branched chain of amylopectin is too short for polyI3 to form the long chain.
Starch is the nutrients stored in the plant body, stored in seeds and tubers, the starch content in all kinds of plants is higher, rice contains 62 86 starch, wheat contains 57 75 starch, maize contains 65 72 starch, and potatoes contain 12 14 starch. Starch is an important part of food, and it feels a little sweet when chewing rice, etc., because the amylase enzyme in saliva hydrolyzes the starch into maltose, a disaccharide. After food enters the gastrointestinal tract, it can also be hydrolyzed by salivary amylase secreted by the pancreas, and the glucose formed is absorbed by the wall of the small intestine and becomes a nutrient for human tissues.
Partial hydrolysis of amylopectin produces a mixture called dextrin. Dextrin is mainly used as a food additive, glue, paste, and in the manufacture (finishing) of paper and textiles.

No, only starch is contained in plant tissues. Animal tissues contain glycogen.

Do not experiment with iodine drips on pork! What is blue has starch, and what is not blue has none.

Summary. Hello dear, happy to answer your <>
Fresh pork does not contain starch, but in some cases, starchy substances such as plain flour, potato flour, corn starch, etc., may adhere to the surface of the pork, which is usually due to processing or transportation. If pork is not handled or stored properly, it may also lead to the growth of starchy substances due to microbial contamination, resulting in a sticky and slippery surface of the pork, but this does not mean that the pork itself contains a lot of starch.
Why some fresh pork contains a lot of starch.
Hello dear, happy to answer your <>
Fresh pork does not contain starch, but in some cases, starchy substances such as plain flour, potato flour, corn starch and other starchy substances may adhere to the surface of the pork, which is usually due to the processing of the imitation or during transportation. If the pork is improperly handled or stored, it can also be held to cause the growth of starchy substances due to microbial contamination, resulting in a sticky and slippery feeling of the mold fluid on the surface of the pork, but this does not mean that the pork itself contains a lot of starch.
Hello dear, expand for you: In order to increase the weight and taste of pork, some merchants may add starch, potato tung powder and other ingredients to pork. Such practices are illegal and affect the health of consumers.
Therefore, when buying pork, it is recommended to choose a regular merchant with legal documents, and thoroughly wash the surface of the pork before cooking to avoid excessive intake of starch components affecting health.
Dear, hello, according to my understanding Tan Xiang, in addition to the improper addition of starch by merchants, starch may also be added to the gravy when cooking pork to increase the taste of fresh juice. While this practice can make pork more palatable, it also increases starch intake. When cooking pork, you should be careful to add starch per mu and control the amount of pork in an appropriate amount to ensure the safety and health of food.

Summary. Dear We are happy to answer for you, and the following are the results for your query; Why some fresh pork contains a lot of starch, because pork contains a lot of muscle cells, and these muscle cells contain a lot of starch, starch is the main energy of muscle cells**, so fresh pork contains a lot of starch.
Dear I am happy to answer for you, the following is the spring fruit for your inquiry; Why do some fresh pork contain a lot of starch, because pork contains a large number of muscle cells, and this is almost careful that some muscle cells contain a lot of starch, starch is the main energy of muscle cells**, so fresh pork contains a lot of starch.
The lean meat I bought back today, I only put soy sauce to marinate, and in the process of kneading Qingyu and inspecting it, a lot of batter-like things were produced, and normal lean meat does not appear this phenomenon, can this kind of meat still be eaten.
Hello dear, please rest assured to eat, it is a <> that can be eaten

Adding starch can keep the moisture of the pork, so that the fried meat is more tender and there is no harm.
Starch contains more than two components with different properties and can be dissolved in hot water, called amylose; It can only expand in hot water, and what is insoluble in hot water is called amylopectin.
Starch is insoluble in cold water. However, when it is heated to boiling point with water, a paste is formed. Commonly known as paste.
This is also called the gelatinization of starch, which has the properties of glue cats. This kind of glue drills produce gelling effect when exposed to cold water, and starch products are made of starch vermicelli and powder skin by using the property of starch. The thickening in cooking also uses the gelatinizing effect of starch to make the dish evenly juiced.
When starch is diluted, it initially forms a variable starch. This is followed by the formation of dextrin, which is soluble in water. Starch in high N (180-200'c) dextrin can also be generated, which is yellow in color.

Yes, generally today's hot dogs are added with starch during processing, so as to make money.

Slices of meat contain protein and no starch.
-
Nope. The main components of animal muscle are protein, lipids, various minerals, vitamins, and water. Starch is mainly found in plants, such as various grain crops, potatoes, some nuts, etc.
However, if it is a semi-finished product of processed meat slices, starch and phosphate excipients will be artificially added for pretreatment in order to retain water, increase tenderness and reduce costs.
Of course, when making meat sliced dishes at home, in order to improve the taste, you can also use starch slurry to starch the starch or thicken before cooking.

Do not wash raw meat before putting it in the refrigerator. After the meat is rinsed, the surface will be covered with a certain amount of moisture, and after being put in the refrigerator, it will form ice scabs, which can easily destroy the nutrients in the meat. It is recommended not to put raw meat in the refrigerator for more than 15 days, and not more than 20 days at most. >>>More
