Embodiment 1

[0034] Take 1 kg of qualified duck egg egg white, stir the egg white evenly, put it in a 60°C water bath, slowly add 2.5mol / L food-grade hydrochloric acid to the egg white while stirring the egg white, reduce the pH of the egg white to 1.5, keep the pH value unchanged, and hydrolyze After 15 minutes, stop adding acid (stirring and water bath conditions remain unchanged), add 50g of duck egg shells until the pH rises to 6.5, stop stirring and water bath, filter to remove the remaining duck egg shells, and add 1.5mol / L food grade dropwise while stirring the enzymatically hydrolyzed egg white Sodium hydroxide solution until the pH of the egg white is 11.0, then degas the egg white at -0.06MPa for 10 minutes, pour the egg white into a round cooking bag, and boil it in a water bath at 100°C for 15 minutes to obtain a high-calcium, high-elasticity, high-transparency egg. intestinal.

Embodiment 2

[0036] Take 1 kg of qualified egg white, stir the egg white evenly, put it in a 55°C water bath, slowly add food-grade lactic acid dropwise to the egg white while stirring the egg white, reduce the pH of the egg white to 2.0, keep the pH value unchanged, hydrolyze for 35 minutes, stop adding Acid (stirring and water bath conditions remain unchanged), add 40g egg shells until the pH rises to 6.5, stop stirring and water bath, filter to remove the remaining egg shells, and add 1.5mol / L food-grade potassium hydroxide solution dropwise while stirring the enzymatic egg white Until the pH of the egg white is 11.5, then degas the egg white at -0.05MPa for 15 minutes, pour the egg white into a square mold, and steam it in steam at 110°C for 8 minutes to obtain high-calcium, high-elasticity, and high-transparency dry eggs.

Embodiment 3

[0038] Take 1 kg of qualified quail egg egg white, stir the egg white evenly, put it in a 55°C water bath, slowly add food-grade acetic acid to the egg white while stirring the egg white, so that the pH of the egg white drops to 2.5, keep the pH value unchanged, hydrolyze for 50 minutes, stop Add acid (stirring and water bath conditions remain unchanged), add 45g of egg shells until the pH rises to 6.8, stop stirring and water bath, filter to remove the remaining egg shells, and add 1.0mol / L food grade sodium hydroxide dropwise while stirring the enzymatic egg white Solution until the pH of the egg white is 10.5, then degas the egg white at -0.06MPa for 10 minutes, pour the egg white into a round cooking bag, and boil it in a water bath at 100°C for 15 minutes to obtain high-calcium, high-elasticity, and high-transparency egg sausages.

Abstract

The invention belongs to the processing field of egg products and particularly relates to a production method of a high-calcium, high-elasticity and high-transparency egg product. The production method comprises the following steps: (1) preparing poultry egg white; (2) carrying out acid hydrolysis on the poultry egg white; (3) adding eggshells which account for 2%-5% of mass of the egg white until the pH value of the egg white approximates to 7.0, stopping water bath and stirring, and filtering to remove residual eggshells, so as to obtain transparent egg white; (4) dropwise adding food-grade alkaline liquid while stirring until the final pH value of the egg white is 10.0-13.0; (5) after the pH value is adjusted, carrying out vacuum degassing on the egg white at a vacuum degree of (-0.05MPa)-(-0.09MPa) for 5-20 minutes; (6) carrying out injection molding; and (7) carrying out thermal treatment on the shaped egg white at 70-115 DEG C for 5-40 minutes, so as to obtain the high-calcium, high-elasticity and high-transparency egg product. The method is simple, safe and short in production cycle, the egg product can be prepared from cracked eggs and hard-shell eggs, the damage caused in an unshelled pickling process can be further avoided, and the safety is high.

Description

technical field [0001] The invention belongs to the field of egg processing, in particular to a method for producing high-calcium, high-elasticity and high-transparency egg products. Background technique [0002] At present, some high-elastic and low-transparency egg products in the market are crystal preserved eggs, and the production cycle of crystal preserved eggs with shells is long, and heavy metal salts (lead salts, copper salts, zinc salts) need to be added during production, and their production is at room temperature. Under the environment, without high temperature treatment, there is a big food safety hazard. [0003] The production of commercially available crystal preserved eggs has the following defects: [0004] 1. The production cycle of pickling with shell is long (30-40 days); [0005] 2. Heavy metal salts (lead salts, copper salts, zinc salts) need to be added during production, which poses potential safety hazards; [0006] 3. Pickled with shell, dama...
