Description

Production process of vegetable protein meat capable of reducing beany flavor and vegetable protein meat
Technical Field
The invention relates to the technical field of food processing, in particular to a production process of vegetable protein meat capable of reducing beany flavor and the vegetable protein meat.
Background
The vegetable protein meat is made up by using defatted soybean powder as raw material through the processes of heating and puffing, etc., and its soybean protein content is up to above 50%. Its color, taste, structure and toughness are similar to those of animal meat, and its protein content is two or three times higher than that of lean meat of pig and ox, and its lysine content is superior to other vegetable protein, and it is non-toxic, harmless, germ-free and nutrient-rich, and its most superiority is that it contains no cholesterol, and has no side effect of animal meat, so that it is one of the health foods for preventing hypertension, arteriosclerosis and angiocardiopathy, and is very beneficial to human body.
However, the beany flavor is a compound flavor of grass flavor, fishy flavor, bitter flavor, odor and the like, and is generated in the puffing process of the vegetable protein meat. The beany flavor of the vegetable meat is not a specific substance, but the combined effect of several or even dozens of flavor components on the human smell is generated, and the beany flavor generates more than 30 volatile substances. The generation mechanism is mainly that lipid substances in the beans are oxidized to generate hydroperoxide, and then the hydroperoxide is decomposed into various volatile micromolecule flavor development substances such as aldehydes, ketones, alcohols, phenols and the like and is combined with the soybean protein. The beany flavor of soy products limits their widespread use as a protein source.

Comparative example 1
Comparative example 1 differs from example 3 in that: the feeding speed of comparative example 1 was 13 to 18 g/s. The remaining parameters were the same as in example 3.
Comparative example 2
Comparative example 2 differs from example 3 in that: the control range of the puffing temperature of the forming section of the comparative example 2 is 120-150 ℃, and the water delivery amount is 1/3-1/4. The remaining parameters were the same as in example 3.
Comparative example 3
Comparative example 3 differs from example 3 in that: the cooling section of comparative example 3 had a puffing temperature range of 50 to 55 ℃. The remaining parameters were the same as in example 3.
Comparative example 4
Comparative example 4 differs from example 3 in that: the screw rotation speed of comparative example 4 was 18 to 20 rpm. The remaining parameters were the same as in example 3.
Sensory testing
The vegetable protein meats of examples 1 to 5 and comparative examples 1 to 4 were cooked in the same manner and divided into 9 groups. 20 volunteers were recruited to taste 9 groups of soybean plant meats, an evaluator gargled three times between tasting each group of samples, the evaluator scored the samples independently, and the single judgment was for a full score of 10. Since the invention aims to verify the effect of removing beany flavor, only an evaluator needs to evaluate the taste and smell. The sensory evaluation criteria are shown in table 1. The scoring (mean) parameters for each panelist pair are table 2.

Figure BDA0003432973810000081
As can be seen from Table 2, the evaluation of the flavor and smell of the vegetable protein meat of examples 1-5 is higher than that of comparative examples 1-2, which shows that the feeding speed, the puffing temperature of the molding section, the puffing temperature of the cooling section and the screw rotation speed are important parameters influencing the existence of beany flavor of the vegetable protein meat. In the comparative example 1, the feeding speed is too high, so that the vegetable protein meat has insufficient residence time in the machine and insufficient temperature rise and still has beany flavor; in the comparative example 2, the puffing temperature of the forming section is lower than 150 ℃, the beany flavor of the puffed plant meat has green grass flavor, and the raw beany flavor is heavier; the puffing temperature of the cooling section in the comparative example 3 is lower than 60 ℃, the too low temperature cooling is easy to enable the plant meat beany flavor volatile substances to be condensed and permeate into the plant meat blanks, and the puffing temperature of the cooling section in the examples 1-5 is controlled to be 60-90 ℃, so that the small molecular volatile substances are favorably gasified quickly, part of the volatile beany flavor substances are taken away instantly, and the beany flavor is reduced. In the comparative example 4, the rotating speed of the screw is lower than that of the screws in the examples 1-5, and the slow rotating speed aggravates the oxidation of the soybean raw material, so that the nutritional ingredients are lost, the characteristic taste of the vegetable protein meat is influenced, and the fragrance is reduced.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
