Description
Technical Field
The invention belongs to the technical field of comprehensive utilization of peanut cake meal, and particularly relates to a method for preparing a sauce-flavor fresh base material by using high-temperature peanut cake meal.
Background
According to statistical figures, about 50% of the peanut resources in our country are used to extract peanut oil. The preference of residents in China for the strong-flavor peanut oil leads the peanut oil preparation process to generally adopt a high-temperature baking and flavoring process to squeeze the peanut oil, and the peanut cake meal generated based on the process is generally called high-temperature squeezing peanut cake meal (high-temperature peanut cake meal for short). Analysis shows that the high-temperature peanut cake contains about 50% of peanut protein, has the characteristics of high nutritional value and few anti-nutritional factors, and is one of high-quality plant protein raw material sources. However, due to the denaturation of peanut protein in the high-temperature baking and aroma-enhancing treatment process, the protein in the high-temperature peanut cake is difficult to fully extract and utilize, so that the high-temperature peanut cake in the prior art is mainly used as feed and fertilizer, and has lower economic value. Therefore, how to efficiently utilize the high-temperature peanut cake meal and improve the additional yield value thereof is one of the problems which need to be solved urgently in the development of the peanut deep processing technology.
The flavor-presenting peptide is also called flavor-enhancing peptide, flavor peptide and delicious peptide, is an oligopeptide with a certain contribution to food flavor and a molecular weight of 500-1500 Da, has the characteristics of natural flavor, mellow delicate flavor, strong extension sense and the like, and can improve the flavor intensity of food. The natural protein can be prepared by taking natural protein as a raw material through a biotechnology, and has good effect on improving the flavor and taste of food in China and improving the grade of the food.
In the prior art, the production method of the taste peptide mainly comprises a chemical method, a microbial fermentation method, an enzymolysis method and the like. The chemical method mainly comprises an acid hydrolysis method and an alkali hydrolysis method, and the acid hydrolysis method is not easy to control the influence of time and temperature on the hydrolysis degree, and the alkali hydrolysis method is easy to generate L-type and D-type amino acid mixtures and cause the loss of nutrient components, so the chemical method is less applied in the actual production. Microbial fermentation and enzymatic processes have also been studied in the prior art, but such processes are highly dependent on the type of raw materials for production, and the technical effects resulting from the different processes often vary greatly. Therefore, based on the characteristic that the high-temperature peanut cake meal raw material is rich in protein, how to develop a preparation method of the flavor peptide with stable effect has important technical significance for further improving the industrial added value of the high-temperature peanut cake meal.
Disclosure of Invention
The invention aims to provide a deep processing method of a sauce-flavor fresh base material by taking high-temperature peanut cake meal as a raw material, thereby laying a certain technical foundation for deep processing of peanuts and further improving the industrial added value of peanut byproducts.
The technical scheme adopted by the invention is as follows:
a method for preparing a sauce-flavor fresh base material by using high-temperature peanut cake meal comprises the steps of pretreating the high-temperature peanut cake meal, carrying out enzymolysis, carrying out Maillard reaction on a product obtained by the enzymolysis, and finally carrying out aftertreatment to obtain the sauce-flavor fresh base material; wherein, the enzymolysis treatment comprises the following steps: adding protease and pancreatin, performing enzymolysis at 50-60 deg.C for 10-20 hr, inactivating enzyme, separating, and collecting supernatant to obtain enzymolysis product.
The pretreatment comprises the following steps: crushing the high-temperature peanut cake meal, sieving the crushed high-temperature peanut cake meal with a 20-80-mesh sieve to obtain high-temperature peanut cake meal powder, adding water according to the mass ratio of 1:5-12, fully and uniformly mixing, treating at 90-120 ℃ for 30-120min, and naturally cooling to 25-60 ℃.
The oil content in the high-temperature peanut cake is not higher than 10%. The edible high-temperature peanut cake/meal after high-temperature pressing and/or solvent oil extraction can be selected.
Further, during enzymolysis, the total dosage of the enzyme is 0.4-1.5% of the mass of the high-temperature peanut cake, wherein the dosage of the pancreatin accounts for 10-50% of the total dosage of the enzyme.
The protease is one or more selected from alkaline protease, flavor protease, compound protease or bromelain, and the initial pH value of the enzymolysis system is 6.0-8.0.
Preferably, the protease is selected from the group consisting of alkaline protease, flavourzyme, complex protease and bromelain, and the four proteases may be mixed in any ratio.
More preferably, the mass ratio of the added protease to the added pancreatin is as follows: alkaline protease, flavourzyme, compound protease, bromelain and pancreatin, wherein the weight ratio of the bromelain to the pancreatin is 1:8:1:1: 1.
The Maillard reaction is as follows: firstly, adjusting the pH value of an enzymolysis product to 5-7, then adding a mixture of ribose, lysine and methionine into the enzymolysis product, then heating for 50-100min at 80-110 ℃, and cooling to normal temperature to obtain the Maillard reaction solution of the peanut flavor peptide.
Furthermore, the amount of the mixture of ribose, lysine and methionine added into the enzymolysis product is 0.2-0.5% of the amount of soluble solid in the enzymolysis product.
The mass ratio of ribose, lysine and methionine in the mixture is preferably 5:8: 3.
The post-treatment can be used for preparing the Maillard reaction solution into paste or powdery sauce-flavor fresh base material.
For example, Maillard reaction solution of peanut flavor peptide can be concentrated under vacuum at 45-70 deg.C until the mass content of solid is 50-65%, to obtain paste sauce flavor fresh base material.
Or concentrating Maillard reaction liquid of the peanut flavor peptide at 45-70 ℃ under vacuum condition until the mass content of solid matters is 20-45%, and then carrying out spray drying under the conditions of air inlet temperature of 150 ℃ and air outlet temperature of 70-120 ℃ to obtain the powdery sauce flavor fresh base material.
Specifically, a method for preparing a sauce-flavor fresh base material by using high-temperature peanut cake meal, which comprises the following steps:
(1) pretreatment of high-temperature peanut cake meal: crushing the high-temperature peanut cake raw material and sieving the crushed high-temperature peanut cake raw material by a sieve of 20 to 80 meshes; weighing 1 part of crushed and sieved peanut cake powder and 5-12 parts of water by mass, and fully and uniformly stirring; treating at 90-120 deg.C for 30-120min, and naturally cooling to 25-60 deg.C;
(2) preparing a peanut cake dreg enzymolysis product: adding mixed enzyme of protease and pancreatin after cooling in the step (1), carrying out enzymolysis for 10-20h at 50-60 ℃ with the initial pH value of an enzymolysis system being 6.0-8.0, inactivating enzyme in boiling water bath, carrying out centrifugal separation at 5-10 ℃ (4000 + 10000r/min and 15-30min), and collecting supernatant to obtain peanut cake enzymolysis products;
(3) the Maillard reaction improves the freshness and aroma enhancement strength of the flavor-presenting peptide: adjusting the pH value of the peanut cake enzymatic hydrolysate to 5-7, adding a mixture of ribose, lysine and methionine which accounts for 0.2-0.5% of the amount of soluble solid substances in the peanut cake enzymatic hydrolysate, heating at 80-110 ℃ for 50-100min, and then rapidly cooling to normal temperature to obtain Maillard reaction liquid of peanut flavor peptides;
(4) concentrating or drying Maillard reaction liquid of peanut flavor peptide:
concentrating: concentrating Maillard reaction solution of peanut flavor peptide at 45-70 deg.C under vacuum condition until solid content reaches 50-65% to obtain paste rich in sauce flavor and fresh base material;
