What is peptone powder?

Peptone is an organic compound. Peptone hydrolyzes meat, casein, or gelatin with acid or protease. It is a light yellow powder with a special meat taste. Peptone can be formed by the decomposition of protein by acid, alkali, or protease. Peptone is rich in vitamins and sugars and contains some organic nitrogen compounds. It is the main raw material of microbial culture medium. Peptone is widely used in the fields of fermentation industry, antibiotics, pharmaceutical industry, biochemical products, and microbiological science research. It can be used to treat digestive tract diseases; different organisms require specific amino acids And polypeptides, so there are various peptones. Generally speaking, animal and plant proteins are the main proteins used to produce peptone.

Peptone can be divided into animal peptone and plant peptone from the source. Tryptone, peptone, bone peptone, etc. They are all animal peptones. Peptones of animal origin also include silkworm pupa peptone, blood peptone, and so on.

As raw materials, products are obtained by an incomplete hydrolysis process. With different sources of protein and different hydrolysis conditions, the composition of the hydrolysate can vary greatly. Therefore, the complex mixture of peptides is usually peptone. It is soluble in water, does not freeze when overheated, and does not precipitate in saturated ammonium sulfate but can be precipitated by a protein precipitation agent. It can be used as an ingredient for microorganisms and animal cell culture media, special functional foods and cosmetics, and as a stabilizer for beer and other products.

Global market trends and market drivers for peptone powder

Due to its complex composition, peptone powder provides various benefits to microorganisms. Peptone powder is suitable for cell culture and is often used in microbial culture media. These multifunctional properties are driving the market demand for peptone powder. There are various other applications for peptone powder.

Due to strict regulations and diseases related to animal peptone meal, plant peptone is becoming increasingly popular as a substitute for meat peptone in the culture medium. This has promoted the growth of the vegetable peptone segment in the global peptone powder market.

Both animal and vegetable proteins and their scraps can be used as raw materials for peptone. For example, it can be prepared with liver residue as raw material, fish meal as raw material, animal glue residue as raw material, pig blood as raw material, and pork bone as raw material.

The following introduces the method of preparing peptone from pork bone—raw materials and proportions of pig bones, lungs, and assorted meats. Anything rich in protein can be used as raw materials. Among them, pig skulls and three major bones are the main ones. Raw material processing Put the prepared raw materials in a pot, rinse it with 40-50℃ water, and then add water, the ratio is 1:1.2 (1:1 is also possible), and more water is needed for bones.

The application and benefit of peptone powder

Peptone contains organic nitrogen compounds, vitamins, and sugars. It is the primary raw material of microbial culture medium. It can be used in large amounts in the fields of antibiotics, the pharmaceutical industry, the fermentation industry, biochemical products, and microbiology scientific research. It can be used to treat digestive tract diseases. There are various peptones because different organisms need specific amino acids and peptides. Generally speaking, the proteins used for peptone production include animal protein, plant protein, and microbial protein. The laboratory is used as a culture medium to cultivate bacteria and used in food to increase protein content. Used in feed, it significantly reduces the production cost of feed mills and is a good product for insufficient protein sources in the feed industry.

Tryptone is a high-quality peptone.

Tryptone is a high-quality peptone, also known as tryptone or tryptone. The peptone is a light yellow powder obtained by the digestion of casein with trypsin and concentrated and dried. It has good physical properties such as light color, is easily soluble, is transparent, and has no precipitation. Various microbial culture media can be prepared.

Casein peptone is made from casein by trypsin hydrolysis and its color is pale yellow or white. Yueshipeptone is a dry powder prepared by special hydrolysis and extraction with protamine as the substrate. Because it is rich in nutrients, it is the basis of various cultural media.

Soy peptone is a light yellow powder extracted by a new process using soybeans as a substrate. It contains a variety of nutrients and is suitable as a raw material for microbial cultivation. Specially used for culturing pneumococcus, streptococcus, brucella, etc. It is rich in nutrition and can also be used as a fermentation raw material for industrial production.

Beef peptone is made from fresh beef

Beef peptone is made of fresh refined beef, refined with the latest technology. It plays a main role in the culture medium to supplement the nutritional deficiencies of peptone and other nitrogen sources. Polyvalent peptone is exquisitely produced by advanced biological extraction technology. It is a light yellow dry powder with extremely rich nutrition and can be used as the basis for a variety of culture media. Suitable for the growth of Neisseria, Salmonella, etc.

Bone peptone is a protein breakdown product, such as casein, silk protein, milk powder, gelatin, beef, soy protein, fibrin, and so on. As raw materials, the product is obtained through incomplete hydrolysis. The commercially available products are mainly light yellow to brownish-yellow powders.

With different sources of protein and different hydrolysis conditions, the composition of the hydrolysate can vary greatly. Therefore, the complex mixture of peptides is usually peptone. It is soluble in water, does not freeze when overheated, and does not precipitate in saturated ammonium sulfate but can be precipitated by a protein precipitation agent. It can be used as an ingredient for microorganisms and animal cell culture media, special functional foods, and cosmetics, as well as a stabilizer for beer and other products.

The peptone powder market

The peptone powder market is subdivided into different industries based on its application, such as the food industry, the pharmaceutical industry, research institutions, and other applications. Other applications include diagnostics, the culture industry, etc. Microbiologists and scientists also use peptone powder for research work in hospitals, veterinary research institutes, sewage treatment plants, and the pharmaceutical industry.

Therefore, the market demand in these industries is higher. In addition, peptone powder is also used to produce antibiotics, vaccines, and oral insulin through fermentation, so the pharmaceutical industry has large market demand. Animal-free soy peptone powder and whey protein hydrolysate peptone powder are used for fermentation, culture media, and vaccine stabilizers. Peptone powder is also used in other non-medium applications such as electroplating, cosmetics, and special diet products.

According to the type, the peptone powder market can be subdivided into microbial peptone, animal peptone, and vegetable peptone. Vegetable peptone is made from plants and grains such as wheat, peas, and potatoes. Animal meat is not used in the production process. Plant peptone provides a new source of supplements with potentially powerful performance characteristics. The market demand for vegetable peptone powder is relatively large. Microbial peptone powder is mainly used in the process of microbial fermentation. Plant pectin is the most famous gelling agent, which is widely used in jams, jams, jellies, and fruit preserves.

As the application of peptone powder continues to grow in the food and biotechnology industries, the Asia-Pacific region is the main exporter and consumer market for peptone powder.

The Processing of peptone powder

Peptone is a water-soluble complex derived from hydrolysis during protein digestion. It is an organic compound and an excellent source of organic nitrogen, peptides, and proteins in the growth of microorganisms and cells. They come from various sources such as meat, casein, gelatin, soy, peas, wheat, potatoes, and other proteins. Peptone is obtained by acid hydrolysis or enzyme decomposition of protein into short peptides and amino acids. The source of protein and the formation of peptone during digestion, these factors determine the degree of amino acids and peptides.

Peptone is mainly used for the growth of microorganisms. In order to provide nutrients to microorganisms, protein must be broken down into peptides and amino acids by enzymatic hydrolysis during the digestion process. Peptone extracted from animal meat and milk digested by proteolysis is very popular in the market.

Peptone pressurization process

Pressurized to extract protein through steam pressure, and care must be taken to ensure that the bones are crisp, not broken, oily, and clear soup. Pressurization process: increase the pressure to 4kgf/cm2 to maintain the pressure balance. If the pressure is uneven, the bones may be broken and the soup may be mixed. The steam can be turned off about 2h after pressure. 

Pay attention to turning off the steam before turning it off the steam. Keep the heat for about 30 minutes to allow the slop oil to separate and make the soup easier. The proportion of auxiliary materials for digestion process and production method: pancreatic digestive enzyme, minced pancreas, add about 10% alcohol, stir well, put it for 24h (alcohol mainly has the function of autolysis, activation, and antiseptic), add Chemicalbook 1:1 when used Stir the water well. 

The ratio of raw materials is about 2%. If the soup is mixed, you can add more. Pay attention that the pancreas should not be rancid. Adjust the pH, take industrial hydrochloric acid, dilute it with tap water to 1:1 for use, and the raw material ratio is to add 2000-3000ml of 1:1 hydrochloric acid per 500kg soup to make the pH 5.2.

Digestion the peptone

Reduce the temperature of the soup to about 5°C, then add digestive enzymes for digestion (after adding digestive enzymes, keep the temperature at 47-49°C), stir frequently to digest well, and add hydrochloric acid after adding digestive enzymes for 2h to adjust the pH.

Boiling soup peptone

add hydrochloric acid to adjust the pH to 5.2, then turn on the steam, heat, and gently stir the bottom of the pot to make the slag float. At this time, the temperature is generally between 80-85°C. After the slag floats, stop stirring and heat to 95-98°C. In the meantime, avoid reaching 100°C. After the slag floats and the soup is clear, the steam can be turned off, and it will be stuffy for about 20 minutes, and the soup will be further clarified.

The characteristic of burning is that the surface slag is turned into small white bubbles. Concentrate the cooked soup, filter it with double gauze, put it in another container, heat it to concentrate, remove the surface foam when it boils, and concentrate it to a Baume degree of 12-14. Dry the concentrated thin paste, put it in an enamel square plate, put it in an oven at 65-70℃, dry it, then grind the dry block into powder and pack it into a bag.
