Example Embodiment

[0017] Example 1

[0018] (1) Chopping: Take 100 kilograms of fresh pig lungs, clean and decontaminate, and use a chopper to grind them into a minced meat shape to obtain minced lungs;

[0019] (2) Steaming: Add 300 kg of water to the minced lungs, stir and mix, adjust the pH to 8.5 with NaOH solution, heat to 98°C, keep cooking for 1.5 hours, filter out the oil floating on the upper layer, get Cooking liquid

[0020] (3) Homogenization: While hot, the cooking liquid is ground and homogenized by a homogenizer for 10 minutes to obtain lung homogenate;

[0021] (4) Enzymatic hydrolysis: adjust the pH value of the lung homogenate to 8.2, add 5.0 grams of alkaline protease per kilogram of fresh lung, heat to 53°C, keep the enzyme hydrolyzed for 2 hours to obtain the enzymatic hydrolysate;

[0022] (5) Spray drying: spray drying the obtained enzymatic hydrolysate to obtain 17.3Kg of lung protein powder.

Example Embodiment

[0023] Example 2

[0024] (1) Chopping: Take 100 kilograms of frozen pig lungs, wash and decontaminate after thawing, and use a chopper to grind them into a minced meat to obtain minced lungs;

[0025] (2) Cooking: Add 400 kg of water to the lung minced material, stir and mix, adjust the pH to 9.0 with NaOH solution, heat to 95°C, keep cooking for 2 hours, filter out the oil floating on the upper layer, and get Cooking liquid

[0026] (3) Homogenization: While hot, the cooking material is ground and homogenized by a homogenizer for 5 minutes to obtain lung homogenate;

[0027] (4) Enzymatic hydrolysis: adjust the pH value of the lung homogenate to 8.8, add 3.5 grams of alkaline protease per kilogram of fresh lung, heat to 52°C, and keep the enzyme for 1.5 hours to obtain an enzymatic hydrolysate;

[0028] (5) Spray drying: spray drying the obtained enzymolysis solution to obtain 15.6Kg of lung protein powder.

Example Embodiment

[0029] Example 3

[0030] (1) Chopping: Take 100 kilograms of fresh lamb lungs, clean and decontaminate, and use a chopper to grind them into a minced meat shape to obtain minced lungs;

[0031] (2) Cooking: Add 350 kg of water to the lung paste, stir and mix, adjust the pH value to 8.8 with NaOH solution, heat up to 98°C, keep cooking for 1 hour, filter out the oil floating on the upper layer, get Cooking liquid

[0032] (3) Homogenization: While hot, the cooking material is ground and homogenized by a homogenizer for 6 minutes to obtain lung homogenate;

[0033] (4) Enzymatic hydrolysis: adjust the pH value of the lung homogenate to 8.6, add 5 grams of alkaline protease per kilogram of fresh lung, heat to 55°C, keep the enzyme hydrolyzed for 1 hour to obtain the enzymatic hydrolysate;

[0034] (5) Spray drying: spray drying the obtained enzymatic hydrolysate to obtain 20.2Kg of lung protein powder.

Abstract

The invention relates to a new method for preparing lung protein powder from animal lung. The method mainly comprises the steps of chopping, cooking, homogenizing, enzymolysis, spray drying to obtainthe lung protein powder. With the animal lung as a raw material and by adopting the biological enzymolysis method combined with the cooking hydrolysis and spray drying technology, the method providedby the invention has the advantages of simple technological process, short production cycle, low cost and no waste or pollution and is suitable for large-scale industrial production. The animal lung protein powder prepared by the invention has the advantages of high protein content and high nutritional value and contains polypeptide, small peptide and amino acid substances, wherein the peptide substances with molecular weight of less than 5,000Da account for 75% or more of total protein, and the small molecule peptides with molecular weight of less than 1,000Da account for 20% or more.

Description

technical field [0001] The invention relates to the technical field of animal by-product processing, in particular to a new method for preparing lung protein powder from animal lungs. Background technique [0002] my country is a large animal husbandry production country. The total production of pigs, mutton sheep and beef cattle ranks among the top in the world. The total amount of various animal lungs produced by slaughterhouses (fields) reaches more than 1 million tons every year, and animal lung resources are very rich. Animal lungs contain more than 70% crude protein in terms of dry matter, about 15% fat and about 4% carbohydrates, and are a kind of cheap animal protein raw materials. However, due to various reasons, except that a small amount of fresh pig lungs are directly eaten and a small part of fresh pig, cattle, and sheep lungs are directly used as aquaculture feed, most of them are discarded and waste, resulting in a huge waste of biological resources. cause se...
