Description
Technical Field
The invention relates to a food processing technology, in particular to a composite concentrated protein and application thereof.
Background
The soybean protein gel is used as a heat irreversible adhesive and is a common adhesive for plant-based foods. In the preparation process, if the soybean protein is added in a dry powder mode, high-speed chopping is required, and meanwhile, the soybean protein is required to have good dispersibility, otherwise, the soybean protein is agglomerated when meeting water (the surface is wet, and the middle is wrapped with powder), the gel performance cannot be normally exerted, and the normal adhesive effect cannot be achieved. However, plant meats generally use fibrous structures of plant fiber-drawing proteins to simulate meat fibrous structures, while the texture of plant fiber-drawing proteins is determined by the fact that strong mechanical processing means such as chopping and twisting cannot be used without damaging the fibrous structures. Therefore, the current technology is to prepare plant-based food by chopping, pulping and mixing with wire drawing at low speed. For example, CN112155115A provides a plant-based ball and a preparation method thereof, which require 4 steps of pulping (the first three steps of high-speed chopping and stirring, and the last step of adding wiredrawing protein and low-speed stirring) to complete uniform mixing, and the process steps are redundant and have low efficiency.
The soy protein concentrate is inexpensive and has been used as a nutritional ingredient in applications. At present, the compound concentrated protein is generally concerned about the preparation process, nutrition and health care performance and taste, and has no specific application to functional exertion. For example, CN111357826a provides a special flour for traditional taste bean products and its products, and the protein raw materials used are all high gel.
The low-temperature defatted peanut protein powder is used as a defatted meal product, has low protein content and poor functionality, can not form gel with certain strength even under the action of glutamine transaminage TG, and is not usually used as a functional protein raw material. If the functional characteristics of the composite concentrated protein can be fully utilized, the concentrated protein can be an ideal raw material for preparing plant-based food and reducing the cost of raw materials.

Detailed Description
The soybean protein gel is used as a heat irreversible adhesive and is a common adhesive for plant-based foods. The protein raw material is added in the form of dry powder, so that the operation is simple and convenient, and the protein raw material is the most commonly used feeding mode in the practical application process, and the protein raw material is required to have good dispersibility and maintain certain functional characteristics. For example, in vegetable meat applications, as a binder, binding the wire drawing proteins functions to plasticity and provide structure. However, the higher the protein content, the lower the degree of protein denaturation, the higher the solubility, and the more functional the protein tends to agglomerate. In the processing process of plant meat, because of the presence of the wiredrawing protein, short-time stirring at medium and low speed is needed, and if the stirring speed is too high and the stirring time is too long, the wiredrawing protein thread structure can be broken. The medium-low speed stirring can lead to high protein content, low protein denaturation degree, high solubility and good functionality of protein raw materials to be easy to agglomerate (surface wetting and internal powder wrapping), so that the protein functionality can not be effectively exerted, and good bonding and structural effects can not be achieved.
Therefore, the invention provides a compound concentrated protein which has certain gel property and can provide good material dispersion characteristics in the preparation process, can be used as a binder for preparing plant-based vegetarian food, can be used as a quality guarantee and cost reduction scheme for bean product production, and can be used as a dispersing agent for other water-difficult-to-disperse raw materials such as colloid.
The schemes herein will be described in detail below.

Typically, when using a drawn protein product, it is reconstituted by conventional means, then dehydrated and then split. The rehydration comprises soaking the wiredrawing protein in water until no hard core exists, and placing the wiredrawing protein after soaking in soft state in a dehydrator to remove redundant water, wherein the weight of the wiredrawing protein after dehydration is about 3 times of the dry weight. The yarn removal can be carried out by a conventional method. For example, the dehydrated wire drawing protein can be placed in a wire drawing protein wire disassembling machine or a rapid beating machine, or a beating machine or a stirring machine can be used for wire disassembling operation, and the columnar, spherical or sheet-shaped wire drawing protein structure is loosely decomposed into muscle fiber filaments by repeated friction and beating of mechanical force.
In the plant-based food of the present invention, the fiber-drawing protein may account for 30 to 60%, such as 40 to 50% or 45 to 55% of the total weight of the plant-based food.
Herein, the starch may be starch conventionally used for plant-based foods, such as various vegetarian foods. In the plant-based food of the present invention, the starch may comprise 1.0 to 5.0%, such as 1.0 to 3.0% or 2.0 to 4.0% of the total weight of the plant-based food.

Flavoring agents and coloring agents in the plant-based food can be selected and added according to actual needs. For example, the flavoring agent may be selected based on the flavor characteristics of the plant-based food. Suitable pigments may be selected so that the prepared plant-based food has the same or similar color appearance as the corresponding meat product. In general, the flavoring and coloring agents may comprise 3 to 8% of the total weight of the plant-based food.
Traditionally, it is thought that alcohol washing of low-functionality protein materials such as soy protein concentrate and low-temperature defatted peanut protein flour, when combined with functional protein, improves dispersibility while reducing gel properties. However, the invention finds that when the compound protein is used together with a cross-linking enzyme (such as glutamine transaminase TG), the compound protein improves the dispersibility and simultaneously improves the gel property. In particular, the present invention has found that the combination of low temperature defatted peanut protein and functional concentrated protein in the presence of cross-linking enzyme instead enhances the initial texture of plant-based food products. Thus, in some embodiments, the plant-based food of the present invention further comprises a cross-linking enzyme. The cross-linking enzymes suitable for use herein may be cross-linking enzymes well known in the art for use in food products, including but not limited to one or more of glutamine transaminase, tyrosinase, lipoxygenase, protein disulfide reductase, protein disulfide isomerase, sulfhydryl oxidase, peroxidase, hexose oxidase, lysyl oxidase, and amine oxidase.

The effect of TG enzyme addition on the initial texture of veal was also studied. Four vegetarian beef products were prepared according to the formulation of application example 21:
(1) The formulation was identical to that of application example 21 (FIG. 6, "example 1 has enzyme");
(2) The formulation was identical to application example 21, but no TG enzyme was added (fig. 6, "example 1 no enzyme"), the TG enzyme content was replaced with water;
(3) The formulation was identical to application example 21, but the complex protein concentrate of comparative example 1 (FIG. 6, "comparative example 1 has enzyme");
(4) The formulation was identical to application example 21, but the complex protein concentrate of comparative example 1 was used, and no TG enzyme was added (fig. 6, "comparative example 1 was enzyme-free"), the content of TG enzyme being replaced with water.
The results are shown in FIG. 6. The results showed that low temperature defatted peanut protein combined with functional concentrated protein reduced the initial texture of the veal (fig. 6, a). However, the low temperature defatted peanut protein was combined with other functional concentrated proteins under the action of glutamine transaminase TG, and the texture of the beef was improved more (fig. 6, b).
