Peptone appears as a light yellow or slightly yellowish brown solid, has a special odor, has strong hygroscopicity, and is an intermediate product of protein hydrolysis. Important media component used in antibiotic or bacterial fermentations. Peptone is an important medium component used in antibiotic or bacterial fermentation. Used in food, feed, etc.
Peptone production method Animal and plant proteins and their scraps can be used as raw materials for peptone. For example, liver residue is used as raw material, fish meal is used as raw material, animal gum residue is used as raw material, and pig blood is used as raw material. Raw materials can be prepared from pig bones
Methods for making peptone
Methods for preparing peptone from pig bones
Ingredients and proportions
Pork bones, lungs and assorted peptones, etc. , anything rich in protein can be used as raw materials, among which pig skulls and three major bones are the main ones, while others contain phosphorus, which does not meet the standards and is detrimental to the cultivation and growth of bacteria.
Ingredients Processing
Put the prepared raw materials into the pot, rinse them with ℃ water, and then add water. The proportion is as much as more bones as more water.
Pressing
Extract the protein through steam pressure. Pay attention to making the bones crisp, not broken, oily and clear. During the pressurization process, increase the pressure to / and keep the pressure balanced. If the pressure is uneven, bones may be broken and the soup may be mixed. Turn off the steam after reaching the pressure. Be careful to turn off the steam first when turning off the steam. Keep it warm so that the oil can be layered to make it easier to put the soup.
Chemical process
Proportion of auxiliary materials and production methods
For pancreatic digestive enzymes, mince the pancreas, add about 10% alcohol, mix well, and set aside for later use (alcohol mainly plays a role in autolysis, activation, and antisepsis) When using, add water and stir well. It is the ratio of raw materials. If the soup is mixed, you can also add more. Be careful not to let the pancreas go rancid. To adjust, take industrial hydrochloric acid, add tap water to dilute it and make it ready for use. The ratio of raw materials is per soup. Add hydrochloric acid until the peptone is digested. When the soup temperature drops to about ℃, you can add digestive enzymes for digestion (after adding digestive enzymes, keep the temperature at ℃). Stir frequently. If the digestion is good, add digestive enzymes and then add Adjust with hydrochloric acid.
Add hydrochloric acid to the peptone soup to boil, heat, stir the bottom of the pot gently to make the slag float. At this time, the temperature is generally between ℃. After the slag floats, stop stirring and heat to between ℃ to avoid When the temperature reaches ℃, turn off the steam after the dregs have floated up and the soup is clear, simmer for about 10 seconds, and further clear the soup. The characteristic of cooking is that the dregs on the surface turn into small white bubbles.
Concentrate the cooked soup, filter it with a double layer of gauze, and put it until In another container, heat and concentrate. When it is slightly boiling, remove the surface foam and concentrate it to Baume.
Dry the concentrated thin paste, put it in an enamel square plate, and put it in the oven. ℃, dry it, then grind the dry pieces into powder and pack it into bags.
