Description

Preparation method of series of instant vegetable egg white sausages
Technical Field
The invention relates to a preparation method of a series of instant vegetable egg white sausages, belonging to the technical field of food processing.
Background
Eggs contain similar protein amino acid composition patterns to human bodies and are one of the most complete food with the recognized nutritional value in the world. In China, eggs are not only a food, but also the components of egg white, egg yolk, shell membrane and the like are used for treating symptoms of heart blood deficiency, insomnia, dysphoria with smothery sensation and the like in traditional Chinese medicine. According to the research report of operation situation and investment strategy of Chinese egg products and processing industry from 2015 to 2020 issued by the Chinese report hall, the annual average scale of the Chinese egg industry is about 3000 hundred million yuan, occupies 40 percent of the whole world and is the first in the world. However, contrary to the current situation of egg product consumption in developed countries, the consumption scale of fresh eggs in China is over 90 percent, and the proportion of egg products is small.
The egg product is used for deep processing of eggs, and can achieve the purposes of balancing nutrition, improving the sensory characteristics and the utilization rate of fresh eggs and the like so as to meet the requirements of different consumers and respond to the policy of national sustainable development. At present, egg products in China are simple in structure and lack innovation, and most of products on the market are traditional marinated eggs, salted eggs, preserved eggs and the like, and are single in taste.
The domestic processing technology of the egg-white sausage can be traced back to the 70 th century in the earliest time, and is developed by a cooked meat product workshop of a meat-processing factory in Beijing. It is called Beijing egg white sausage, and has main materials of fat meat, lean pork and salted duck egg white. Other process designs are adjusted around the raw meat and egg white afterwards, and the product is monotonous in appearance, soft in sensory quality and lack of chewiness. Therefore, the invention provides a method for improving the hardness and elasticity of egg white intestines by combining protein powder addition, preheating treatment, glutamyl transaminase (TG enzyme) addition and refrigeration treatment, and the taste of the egg white intestines can be improved to ensure that the egg white intestines are elastic and tasty.
Different from meat sausage products, the natural egg white sausage has pure white color, and is beneficial to regulating and controlling the color of the final product by adding other components so as to improve the sensory enjoyment of consumers, particularly the consumers of the younger age. The vegetables contain abundant nutrients such as vitamins, minerals and dietary fiber, and can be added into egg white sausage to increase nutrients. According to the invention, vegetables with typical colors are selected, soaked, and combined with the adjustment of the pH value of a system, vegetable egg white sausage with a series of colors can be finally obtained; in addition, the aromatic substances of the vegetables can also add refreshing fragrance to the egg white sausage. In conclusion, the product innovates the traditional egg white sausage from the sensory angle and the texture angle, and provides reference for the research and development of high-quality egg products.

Effect test
The determination method comprises the following steps:
and (3) texture determination: cutting vegetable egg white sausage into 2cm diameter and 2cm height cylinders. A P/R36 type probe is selected, the speed before measurement is 5.00mm/sec, the speed during measurement is 2.00mm/sec, the speed after side measurement is 2.00mm/sec, the target mode is strain, the strain parameter is 50%, the trigger mode is automatic (force) and the time is 5.00 sec. The probe return distance was set to 25mm, the return speed was set to 20mm/Sec, and the contact force was 50 g.
And (3) measuring color difference: the vegetable egg white sausage is taken and placed in a test box, the central part of the vegetable egg white sausage is measured by a WSC-S colorimeter, and the average value is obtained by measuring each sample for 3 times. Wherein L represents a brightness value, a represents a redness value, and b represents a yellowness value. The calibration of the colors was done with a standard CR-400 whiteboard.
The above assays may also be determined using other assay methods conventional in the art.
Experiment 1 the treatment method was adjusted based on example 4 of the present application, and other steps were performed in parallel, and the specific results are shown in table 1:
TABLE 1 comparison of the quality of the vegetable egg white intestines under different treatments
Figure BDA0003653232550000061
Note: different letters in the same column indicate significant differences (P < 0.05).
The method combining protein powder addition, preheating treatment, TG enzyme addition and refrigeration treatment is adopted, so that the hardness, elasticity and chewiness of the product are obviously improved, and the preheating treatment and the TG enzyme addition have obvious synergistic effect.
Experiment 2 the additive condition and the treatment mode were adjusted based on example 1 of the present application, and other steps were performed in parallel, and the specific results are shown in table 2:
TABLE 2 comparison of color difference results of purple potato egg-white sausage under different treatments
Figure BDA0003653232550000062
Note: different letters in the same column indicate significant differences (P < 0.05).
In the control group, the appearance of the product is gray white, and the original color of the purple sweet potato is almost lost. After the vegetable soaking and pH regulation system is used for combined treatment, the brightness value and the redness value of the product are obviously increased, the yellowness value is obviously reduced, the appearance is purple, and more excellent product color is obtained.
The above examples are for illustrative purposes only and are not intended to limit the present invention, and practitioners in the relevant art will recognize that any modifications, omissions, substitutions, and equivalents, which fall within the spirit and scope of the present invention, are included.
