The plant protein meat, also called simulated meat and artificial meat, is different from traditional 'simulated' vegetarian meat, is an 'image version' of animal meat, and the simulation of meat structure, flavor, taste and the like is infinitely close to real meat. The plant protein meat has wide development prospect, is a large scheme for solving the human survival problem from the environmental point of view, can ensure the continuous and stable meat output in the future and meet the nutritional requirements of human survival. From the aspect of health, the plant protein meat can reduce the health risks brought by high fat and high cholesterol.
The konjac gum has the characteristics of thickening property, water absorption property and gel property, and can be used in various vegetarian products. After the glucomannan in the konjac glucomannan is gelatinized, the viscosity changes along with the temperature change, and the konjac glucomannan can become a heat irreversible gel only under an alkaline condition, so that the konjac glucomannan is applied to vegetable protein meat, however, the flavor of food is greatly influenced by the accompanying alkaline taste.

The sensory quality evaluation indexes of the vegetable protein meat are shown in table 1.
TABLE 1
The sensory evaluation results of the vegetable protein meat prepared in the embodiments 1-4 of the invention are shown in Table 2.
TABLE 2
As can be seen from table 2, compared to the vegetable protein meat prepared by washing in the pre-forming process and adding the acid-controlled release emulsion, the vegetable protein meat obtained without washing in the pre-treatment has larger beany flavor and deteriorated odor, while the vegetable protein meat without adding the acid-controlled release emulsion has prominent alkali flavor and is not acceptable to the examiners.
Example 5
The flavor analysis of the vegetable protein meat, the gas chromatography-mass spectrometry analysis process: the sample is not split, the temperature of the furnace box is increased to 180 ℃ from 60 ℃ at the speed of 10 ℃/min, the carrier gas is helium, and the flow rate is 0.8 mL/min. Mass spectrum conditions: the ionization mode is EI, the electron energy is 70eV, the ion source temperature is 200 ℃, and the interface temperature is 250 ℃. The full scanning mode is adopted, and the range is 50.0-500.0 m/z.
The hexanal is the most main beany flavor substance, and the invention judges the weakening degree of the beany flavor of the vegetable protein meat processed in the early stage such as washing and acid-adding slow-release liquid according to the hexanal content. The flavors of the protein meat (vegetable protein meat without pork flavor) prepared in the examples 4, 3 and 1 of the present invention are shown in fig. 1, 2 and 3. As can be seen from fig. 1, 2 and 3, the strength of the undesirable off-flavor such as hexanal (retention time of 7.392min) is significantly reduced in the washed and acid-added slow-release liquid-added vegetable protein meat sample compared with the unwashed and acid-added slow-release liquid-added vegetable protein meat sample, which indicates that the off-flavor of the structured protein itself (e.g., beany flavor in soy protein) and the alkali flavor problem caused by konjac gum can be effectively reduced in the vegetable protein meat prepared by the washing and acid-added slow-release liquid in the pre-forming process. Meanwhile, the pork essence is added into the pork essence, so that the flavor of the pork essence is prominent, and the overall profile is closer to the real flavor of the pork essence, as shown in fig. 4.
On the basis of the embodiment 1, (1) no washing and no acid slow-release solution is added; (2) washing without adding acid sustained-release solution; (3) washing, adding acid delayed release solution, and making into protein meat (vegetable protein meat without pork essence), as shown in Table 3.
TABLE 3
As can be seen from table 3, compared with the vegetable protein meat samples without washing and acid-added slow-release solution, the content of the vegetable protein meat aldehyde compounds subjected to washing treatment is reduced, especially the content of hexanal, which is a typical beany flavor substance, is remarkably reduced, and the esters, ketones, alcohols and acids are increased to a certain extent. Through washing and treatment of the acid-added slow-release solution, the content of ester and alcohol compounds is increased more than that of the plant protein meat subjected to washing treatment only, but the content of aldehyde compounds is obviously reduced. Generally speaking, the contents of ketone, alkane, acid and furan compounds have no significant difference along with the pretreatment processes of washing and adding acid slow-release solution, but the influence rule on esters, aldehydes and alcohols is obvious. The content of beany flavor substances, particularly hexanal, in the vegetable protein meat which is washed and treated by the acid slow-release solution is reduced, and the content of aromatic substances such as esters and alcohols is obviously increased.
Example 6
On the basis of example 1, the influence of the volume ratio of acid, agar/sodium alginate, water and oil on the sensory quality of the vegetable protein meat is controlled (pork essence is not added), other conditions are the same as example 1, and the test conditions and results are shown in table 3.
TABLE 3
As can be seen from table 4, the acid: agar/sodium alginate: water: grease 1: 1: 40: at 58, the sensory score was highest, with less acid added, there was a clear alkaline taste, while the excess taste was worsened, at which time the hexanal content was lowest. When the addition amount of the agar/sodium alginate is less, a film layer can not be formed to wrap the acidic substance, so that the acidic substance flows out too early, and the alkaline substance is neutralized, so that the strength of gel formed by the konjac gum is weak, the texture of the vegetable protein meat is poor, the total taste score is low, when the addition amount of the agar/sodium alginate is more, the viscosity of the system is increased, and the taste of the finally obtained vegetable protein meat is sticky. The oil has special fragrance, and more or less oil can have adverse effect on the appearance, smell, taste, mouthfeel and the like of the final vegetable protein meat.
Thus, the present invention prefers acids: agar/sodium alginate: water: grease 1: 1: 40: 58, the prepared acid slow-release emulsion effectively achieves the purpose of neutralizing alkali, and the prepared vegetable protein meat achieves the best taste. When out of the scope of the present invention, the flavor substances therein are not good.
In conclusion, the preforming process of the vegetable protein meat provided by the invention solves the problem of alkali taste caused by alkali dissolution of konjac gum and the problem of peculiar smell of vegetable protein, so that the finally prepared vegetable protein meat is close to the taste of real meat, has good flavor and meets the health requirements of people on low fat and low cholesterol. The invention solves the problem of alkali taste caused by alkali dissolution of konjac gum by means of slowly releasing acid, utilizes a film layer formed by hydrophilic colloid to wrap an acid substance, and the mixture is thermally disintegrated in the heating process of the plant protein meat, thereby releasing the acid substance and achieving the aim of neutralizing alkali.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
