Problems solved by technology

[0006] Existing collagen is mainly extracted from animal bodies, such as extracting collagen and chondroitin sulfate from bovine cartilage in Chinese patent 200710040969.1, extracting collagen from pig, cattle, and sheep bones in Chinese patent 201110090110.8, and extracting collagen from chicken bones in However, the annual output of broiler chickens in my country has reached more than 8 million tons, and the processing of chicken parts has resulted in the accumulation of a large number of chicken skeletons. 90% of the protein in chicken bones is collagen, but it has not been well

Embodiment 1

[0019] (1) Raw material processing: Put 200kg of chicken bone raw material into the cutting machine at a constant speed and cut it, transport it to the meat grinder, and add water continuously at the same time. When feeding, the water temperature is controlled at 55°C, and the mass ratio of material to water is controlled at 1: 1.5; the above Put the bone residue into the hydrolysis tank, add bone residue cleaning water into the hydrolysis tank, raise the temperature to 85°C after feeding, keep warm and stir for 2 hours, stop stirring and let it stand for 35 minutes, and directly separate the chicken fat floating on the upper layer;

[0020] (2) Preparation of chicken fat: Put the chicken fat separated in step (1) into the oil storage tank, turn on the jacket steam and stir it, then let it stand for sterilization for 1.5 hours after the temperature rises to 95°C, until the fat layer is completely separated, turn on The bottom valve of the tank discharges the water phase liquid,...

Embodiment 2

[0026] (1) Raw material processing: Put 200kg of chicken bone raw material into the cutting machine at a constant speed and cut it off, transport it to the meat grinder, and add water continuously at the same time. When feeding, the water temperature is controlled at 65°C, and the mass ratio of material to water is controlled at 1: 2; the above Put bone residue into the hydrolysis tank, add bone residue cleaning water into the hydrolysis tank, raise the temperature to 90°C after feeding, keep warm and stir for 3 hours, stop stirring and let stand for 40 minutes, and directly separate the chicken fat floating on the upper layer;

[0027] (2) Preparation of chicken fat: put the chicken fat separated in step (1) into the oil storage tank, turn on the jacket steam and stir, and let it stand for sterilization for 2.5 hours after the temperature rises to 99°C until the fat layer is completely separated, and then turn on The bottom valve of the tank discharges the water phase liquid, ...

Abstract

The invention discloses a method for making collagen protein film coproduction organic compounds. The method is characterized by comprising the following steps: (1) processing raw materials; (2) preparing chicken oil; (3) performing two-step enzymolysis; (4) preparing soluble calcium powder; (5) making composite liquid; and (6) making protein films. According to the method disclosed by the invention, the adoption of a two-step enzymolysis technique, the quality of collagen is improved; at the same time, enzymolysis protective agents are added into the enzymolysis process, so that the excellent quality of products is ensured; and calcium in the chicken bones is prepared into soluble calcium through acid activation on citric acids, so that the biological absorption rate of the calcium is increased. Dialdehyde starch is added, so that the mechanical property, the heat stability and the moisture resistance of the collagen are greatly improved; the collagen is easy to degrade, and the collagen has excellent environmental protection performance; and the production process is clean, green and pollution-free, no waste water is drained, and the purpose of the clean comprehensive utilization of the chicken bones is realized.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of agricultural and sideline products, and relates to a method for producing collagen film and co-producing organic matter. Background technique [0002] Collagen is one of the main components of the human tissue structure. It spreads throughout the various tissues and organs of the body, such as: skin, bones, cartilage, ligaments, cornea, various endometrium, fascia, etc., and is responsible for maintaining the shape and structure of skin and tissues and organs. It is also an important substance for repairing various damaged tissues. [0003] At present, in the process of producing hydrolyzed collagen at home and abroad, most of the hydrolyzed collagen obtained by hydrolyzing animal bones, skins and other tissues by conventional methods has a wide molecular weight range and poor molecular weight uniformity; moreover, a large number of free amino acids produced during the hydrolysis proces...
