Detailed Description
The technical scheme of the invention is further described below with reference to the specific embodiments.
The raw materials of the rock sauce comprise pure water, 24 ℃ palm oil, glucose, white granulated sugar, whole milk powder, corn starch, carrageenan, gel-type whey protein powder, gel-type egg powder and cheese powder.
It is worth to say that, in order to make the roasted sauce not stick to the bag after baking, the invention adopts gel type whey protein powder, gel type egg powder, corn starch, carrageenan and 24 ℃ palm oil to compound, and the roasted sauce has oil wettability and gel property after baking and can not stick to the packaging bag.
Specifically, gel-type whey protein powder and gel-type egg powder play a main role in emulsification in a system to form an oil-in-water system, have gelation properties, and keep a certain coagulation state of the roasted sauce after baking, so that the sauce is prevented from sticking to a bag; the corn starch has gel property besides thickening effect, so that the rock sauce tastes fresh; the carrageenan has the function of emulsification stabilization, and also has fresh and smooth taste. As the gel-type whey protein powder, the gel-type egg powder, the corn starch and the carrageenan all have gel property, after being compounded and used, the prepared rock-burned sauce is smeared on toast or other baked foods, so that the rock-burned sauce can keep a certain gel state after being baked, the condition that the rock-burned sauce on the surface of the baked foods is adhered to a packaging bag after being packaged is avoided, and the 24 ℃ palm oil is added into the rock-burned sauce, so that the surface of the baked rock-burned sauce has oil wettability, and meanwhile, the melting point of the 24 ℃ palm oil is relatively high compared with that of liquid oil, the consistency of the rock-burned sauce at normal temperature can be improved, a certain solid state is maintained, the condition that the rock-burned sauce sticks to bags are further avoided, and waste and bad experience of consumers are avoided.
The raw materials of the rock sauce are mainly composed of glucose, white granulated sugar, gel-type whey protein powder, whole milk powder and cheese powder, so that the rock sauce is fragrant and sweet in taste and generates a rock-burning effect after baking, and proteins in the gel-type whey protein powder, the whole milk powder and the cheese powder can react with the glucose and the white granulated sugar in a Maillard reaction manner in the baking process, so that the skin of the rock sauce forms a caramel plaque, the rock-burning effect is generated, the color is attractive, and the rock-burning effect is fragrant and sweet in taste.
Preferably, in the raw materials of the rock sauce, the sum of the weights of gel-type whey protein powder, gel-type egg powder, corn starch, carrageenan and palm oil at 24 ℃ is 0.2-0.5 times of the total weight of the raw materials of the rock sauce.
Preferably, the raw materials of the rock sauce further comprise high fructose syrup, sorbitol solution, glycerol, trehalose and salt;
the water activity of the rock sauce is less than or equal to 0.86.
Further, the water activity refers to the ratio of the equilibrium vapor pressure of a certain food to the saturated vapor pressure of pure water at the same temperature in a closed space, the water activity of pure water is equal to 1.0, the water activity is free water molecules in the food, and the water molecules are the necessities for reproduction and survival of microorganisms, the water activity of most fresh foods is 0.99, and the water activity capable of inhibiting the growth of most bacteria needs to be lower than 0.91, for example, the water activity suitable for the growth of most microorganisms is 0.94-0.99, and the water activity suitable for the growth of most mold is 0.87-0.94.
Most microorganisms are at normal temperature or slightly higher than normal temperature as the optimal growth temperature, at this time, the growth and reproduction of the microorganisms are facilitated, and a certain amount of minimum water activity and proper pH are required for the growth and reproduction of the microorganisms, so that the technical scheme mainly utilizes the characteristics of the microorganisms, and the growth of the microorganisms is inhibited by a method of reducing the water activity and the pH of the rock-burning sauce, so that the time of preserving the rock-burning sauce at the normal temperature is prolonged, the rock-burning sauce can be preserved at the normal temperature of 25 ℃, the preservation and transportation at the temperature of 4 ℃ or below are not needed, the cost of preservation and transportation is reduced, and the sales area of the rock-burning sauce can be enlarged.
Specifically, the technical scheme improves the mass percentage of solids (raw materials except water) in the rock-burning sauce to 65% or more, reduces the proportion of the solution-shaped raw materials in the raw materials, and can effectively reduce the water content in the rock-burning sauce, thereby greatly reducing the water activity in the rock-burning sauce. And the high fructose corn syrup, the sorbitol solution, the glycerol, the trehalose and the salt are added into the rock sauce, and can be combined with water molecules to reduce the content of free water, so that the water activity is further reduced, the water activity of the rock sauce is less than 0.86, the growth and the reproduction of microorganisms are inhibited, the rotten and spoiled rock sauce is avoided, and the shelf life is prolonged.
The quality guarantee period of the rock sauce prepared by the technical scheme can reach 6 months at normal temperature, and the rock sauce can be stored for 3 months after being smeared on toast or cake, baked and packaged.
Preferably, the raw material of the rock sauce further comprises an acidulant, wherein the acidulant is one or two of citric acid, malic acid and lactic acid;
the pH value of the rock sauce is 5.4-5.6.
Specifically, citric acid, malic acid and lactic acid are all organic acids, are healthy green products naturally occurring in nature, and have no added limit. The organic acid generally has a refreshing sour taste, and most of inorganic acid has a bitter taste, so that food is deteriorated, and the sour agent used in the technical scheme is organic acid, wherein citric acid is the most widely distributed organic acid in fruits and vegetables, is the most widely used sour agent in the food industry, can prevent food from spoilage, and can also be used as a color fixative and a synergist of an antioxidant; the malic acid has a sour taste, is particularly pleasant, has acidity greater than that of citric acid, and is soft in taste; the lactic acid has unique sour taste, moderate temperature, and has the functions of regulating pH value, inhibiting bacteria, keeping food color, etc.
It is worth to say that, because most of food microorganism growth and propagation need to be in neutral or weak alkaline environment, the technical scheme further inhibits the microorganism growth and prolongs the shelf life of the rock-burning sauce by adding a proper amount of sour agent into the rock-burning sauce to reduce the pH value of the rock-burning sauce. If the pH value of the rock sauce is higher than 5.6, the effect of inhibiting the growth of microorganisms is poor, and if the pH value of the rock sauce is lower than 5.4, the taste of the rock sauce is slightly sour, and the taste of the rock sauce is affected.
Further, the raw materials of the rock sauce comprise, by weight, 280-340 parts of pure water, 250-350 parts of 24 ℃ palm oil, 40-60 parts of glucose, 60-80 parts of white granulated sugar, 20-50 parts of trehalose, 20-30 parts of whole milk powder, 8-12 parts of corn starch, 0.3-0.5 part of carrageenan, 80-120 parts of high fructose syrup, 30-50 parts of sorbitol solution, 20-40 parts of glycerol, 15-25 parts of gel-type whey protein powder, 3-8 parts of gel-type egg white powder, 5-10 parts of edible salt, 5-10 parts of cheese powder and 1-2 parts of sour agent.
It is worth to say that if the amount of pure water added is large, the water activity increases, which affects the preservation time of the finished product, and the state after baking is also thin, so that the bag is easy to adhere, and if the amount of pure water added is too small, the state is thick, which is not beneficial to the smearing operation; if the addition amount of palm oil is too small at 24 ℃, the taste of the rock sauce is not smooth, the rock sauce has no soft feel, the bag is easy to adhere after baking, and if the addition amount is too large, the emulsification state is unstable. The adding amount of glucose is less, the Maillard reaction is weakened, the rock burning effect is poor after baking, if the adding amount of glucose is too large, the Maillard reaction is too strong, the baking coloring is too deep, and the crystallization is easy to separate out when the content of glucose is high; when the addition amount of the white granulated sugar is too small, the sweetness is reduced, the taste is poor, and when the addition amount of the white granulated sugar is too large, the sweetness is larger; when the addition amount of the trehalose is too small, the effects of reducing the water activity, delaying the starch aging and inhibiting the deterioration of protein and lipid are not achieved, so that the preservation time of the finished product is reduced, and when the addition amount of the trehalose is too large, the sweetness of the product is reduced, and the cost is increased. If the addition amount of the full-fat milk powder is too large, the protein content is high, the baking coloring is too deep, bacteria are easy to grow, the finished product is easy to spoil and deteriorate, and if the addition amount of the full-fat milk powder is too small, the flavor is insufficient, the protein content is low, and the color is light after baking; if the addition amount of the corn starch is too large, the gel property of the rock-burning sauce is strong, the aging and hardening are easy, and if the addition amount of the corn starch is too small, the gel type of the rock-burning sauce is reduced, and the bag is easy to adhere; if the added amount of carrageenan is too large, the taste can be affected due to too thick sauce state, and if the added amount of carrageenan is too small, gel is weakened and the paste is easy to stick to a bag after baking. The fructose syrup is excessively added, so that the sweetness of the sauce is excessively large, the adding amount is excessively small, and the effect of reducing the water activity is not better achieved; if the addition of sorbitol is too large, flatulence is caused, diarrhea occurs, and if the addition of sorbitol is too small, the water activity is difficult to be well reduced; if the addition amount of the glycerol is too large, unpleasant aftertaste is generated, and if the addition amount is too small, the water activity is not well reduced; if the gel-type whey protein powder and the gel-type egg powder are excessively added, the protein content is high, microorganisms are easy to grow, the baking coloring is deeper, the baking effect is affected, the gel property is stronger when the gel-type whey protein powder and the gel-type egg powder are excessively added, the paste is excessively thick and is difficult to paint, and if the addition amount of the gel-type whey protein powder and the gel-type egg powder is excessively small, the good coloring effect, the emulsification effect and the gel effect are not achieved, and the burnt paste is unstable in emulsification, easy to oil separation and emulsion breaking, not resistant to baking and easy to adhere to bags; if the addition of the edible salt is too large, the taste of the roasted sauce is affected, the protein is denatured, and if the addition of the edible salt is too small, the water activity is not well reduced, and meanwhile, the taste is also affected; if too much cheese powder is added, the consistency of the stuffing is too high, the cost is too high, the addition of the cheese powder is too little, and the cheese flavor is insufficient, so that the overall taste of the rock-burned sauce is affected; if the addition of the sour agent is too much, the protein is denatured, the sour is too much, and if the addition of the sour agent is too little, the pH of the sauce cannot be reduced, bacteria are easy to grow, and the shelf life of the rock-burned sauce product is influenced.
Specifically, gel-type egg white powder is produced from Dalian Han Wei food Co.
Preferably, the raw materials of the rock sauce further comprise 20-50 parts of hydroxypropyl distarch phosphate, 1-3 parts of microcrystalline cellulose and 0.5-1.5 parts of xanthan gum according to parts by weight.
Because the hydroxypropyl distarch phosphate has the advantages of thickening, shearing resistance, good freeze thawing stability and ageing resistance, the viscosity and ageing resistance of the rock-burning sauce can be increased by adding the hydroxypropyl distarch phosphate into the rock-burning sauce, and the hydroxypropyl distarch phosphate keeps good stability when the rock-burning sauce is frozen and thawed, so that the rising or agglomeration of the apparent viscosity of the rock-burning sauce is avoided.
Specifically, the carrageenan, microcrystalline cellulose and xanthan gum are compounded for use, so that the carrageenan, microcrystalline cellulose and xanthan gum have a synergistic effect, play a role in emulsion stabilization, and enable the taste to be fresh and smooth.
Preferably, the raw materials of the rock sauce further comprise, by weight, 0.2 to 1 part of potassium sorbate, 0.1 to 0.4 part of sodium dehydroacetate, 1.0 to 1.4 parts of beta-carotene (1% content) and 0.04 to 0.07 part of disodium ethylenediamine tetraacetate.
The technical scheme can effectively prolong the preservation time of the roasted sauce and the roasted sauce products at normal temperature by controlling the water activity and the pH value, and simultaneously, the trace potassium sorbate and the sodium dehydroacetate are added as the preservative to inhibit the growth and reproduction of mold or yeast so as to further prolong the preservation time of the roasted sauce at normal temperature. If only two preservatives, potassium sorbate and sodium dehydroacetate, are added, the water activity and the pH value are not reduced at the same time, so that the preservative effect is reduced and the shelf life is shortened. The preservative effect of the preservative is affected by factors such as water activity, pH value, food contamination, dissolution and dispersion of the preservative, and the like. The dielectric or soluble substance is added to the water to a concentration that reduces the water activity, thus providing a synergistic effect on the preservative. The preservative effect of potassium sorbate is related to the pH value of food, is an acidic preservative, has better bacteriostatic effect when the pH value is lower, and is preferably used below 6. The pH, water activity, preservative produce a combined effect in which neither factor alone is sufficiently bacteriostatic to act together to prevent microbial growth.
Specifically, disodium ethylenediamine tetraacetate is added into the raw materials of the rock sauce as an antioxidant, so that the oxidation of lipid can be delayed, and the flavor of the rock sauce can be maintained; beta-carotene (1% content) is an orange fat-soluble compound, is the most ubiquitous and stable natural pigment in nature, and can be added into the rock sauce to adjust the color of the rock sauce by a small amount of beta-carotene (1% content), so that the rock sauce has better color.
Preferably, the raw materials of the rock sauce further comprise 1-3 parts of food essence.
Specifically, the essence for food in the formula contains MicroGARD natural flavor substances, is a microbial metabolite obtained by fermenting glucose and cow milk as matrixes, can effectively inhibit bacteria, yeast, mould and the like, can prevent the spoilage of microorganisms in the roasted sauce, can further prolong the preservation time of the roasted sauce, and can reduce the dosage of chemical preservatives.
Further, the use of the rock sauce in baked goods including toasts, cakes and breads.
A method for preparing a rock sauce for preparing the rock sauce, comprising the following steps:
(1) Weighing the raw materials according to the formula ratio, and dividing the raw materials into liquid raw materials and powder raw materials;
(2) After the liquid raw materials and the powder raw materials are respectively and uniformly mixed, adding the powder raw materials into the liquid raw materials to obtain mixed raw materials;
(3) Adding the mixed raw materials into a high-shear emulsification pump, slowly adding the heated palm oil at 24 ℃ into the high-shear emulsification pump, and uniformly dispersing to obtain a crude product of the rock-burned sauce;
(4) And (3) adding the crude product of the rock-burned sauce into a high-pressure homogenizer for homogenization, adding into a scraper type heat exchanger for gelatinization sterilization treatment, cooling, and automatically filling to obtain the product of the rock-burned sauce.
The method is characterized in that the mixed raw materials and the heated palm oil at 24 ℃ are subjected to high-speed operation by a high-shear emulsification pump, so that the raw materials of the rock-burned sauce are fully mixed, stirred and thinned to form a suspension-like rock-burned sauce crude product, the rock-burned sauce crude product is conveyed to a high-pressure homogenizer, and the rock-burned sauce crude product is subjected to high-speed shearing, high-frequency oscillation, cavitation, convection impact and other mechanical force actions and corresponding thermal effects in the high-pressure homogenizer, so that the mechanical force and chemical effect caused by the mechanical force and the chemical effect can induce the physical, chemical and structural properties of macromolecules in the rock-burned sauce crude product to change, and finally the homogenizing effect is achieved.
The method comprises the steps of homogenizing a crude product of the rock-burnt sauce under high pressure, carrying out high-temperature short-time gelatinization sterilization and rapid cooling by adopting a scraper type heat exchanger, continuously scraping and transferring heat by using a scraper to enable a boundary layer of the material to be continuously replaced by a new material, obtaining a very high heat transfer coefficient, simultaneously avoiding bad phenomena such as coking films and the like on a heat transfer surface, scraping and stirring the scraper to enable the rock-burnt sauce to be fully mixed, enabling the gelatinization of the rock-burnt sauce to be uniform and effective, carrying out rapid cooling after sterilization, enabling the state of the rock-burnt sauce to be stable, and finally carrying out filling by using an automatic packaging machine to obtain the rock-burnt sauce product.
Specifically, the liquid raw materials comprise pure water, fructose syrup, sorbitol solution, glycerol and essence for food, and the powder raw materials comprise glucose, white granulated sugar, trehalose, whole milk powder, corn starch, hydroxypropyl di-starch phosphate, carrageenan, microcrystalline cellulose, xanthan gum, gel-type whey protein powder, gel-type egg powder, edible salt, potassium sorbate, sodium dehydroacetate, cheese powder, beta-carotene (1 percent), disodium ethylenediamine tetraacetate and sour agent.
Further, in the step (3), the temperature of the palm oil after being heated at 24 ℃ is 55-60 ℃, and the rotating speed of the high-shear emulsification pump is 3000r/min;
in the step (4), the pressure of the high-pressure homogenizer is 20MPa.
It is worth to say that the high tangential velocity and the strong power brought by the high frequency mechanical effect generated by the rotor of the high shear emulsifying pump under the high speed rotation make the material receive the strong combined actions of mechanical shearing, centrifugal extrusion, liquid layer friction, turbulence, etc. in the narrow interval of stator and rotor, so that the mutually insoluble two phases are uniformly dispersed and emulsified under the combined action of the proper process and proper amount of additive, and the stable rock-burned sauce product is obtained. The highest speed of a general production type high-shear emulsification pump is 3000r/min, in a certain shearing speed range, the larger the shearing speed is, the smaller the size and the more uniform the distribution of liquid drops are, the liquid drops are less prone to aggregation, so that stable emulsion is formed, the stability of the emulsion cannot be enhanced due to overlarge shearing speed, and if the shearing speed is too low, a good emulsification effect cannot be achieved, the rotating speed of the high-shear emulsification pump is set to 3000r/min when the rock-burnt sauce is prepared.
In general, the higher the pressure of the high-pressure homogenizer is, the smaller and more uniform the particle size of the homogenized material is, but the higher the homogenizing pressure is, the higher the heating degree of the material is, and the high temperature can influence the emulsifying effect of the material; if the pressure is too low, the small emulsified particle size can not be achieved, the state is unstable, and the materials are easy to oil out, so the pressure of the high-pressure homogenizer is 20MPa.
At normal temperature, 24℃palm oil tends to agglomerate and is not conducive to emulsification mixing, so that for better emulsification, 24℃palm oil is heated to 55 to 60℃and preferably 24℃palm oil is heated to 60 ℃.

TABLE 2 detection results of the rock-burned pastes of comparative examples 1-2
/>
As can be seen from the above raw material formulation of comparative example 1 and table 2, the formulation of the rock-burnt sauce in comparative example 1 is substantially the same as that of example 1, except that the weight parts of gel-type whey protein powder and 24 ℃ palm oil are reduced, and gel-type egg powder is not added to the raw material, so that the prepared rock-burnt sauce is insufficient in oiliness and geliness after baking, and is easily stuck to a packaging bag when being smeared on toast or cake, causing waste and affecting the sense of consumers.
As is clear from the raw material formulation of comparative example 2 and Table 2, the weight portion of pure water in comparative example 2 is high, the weight portion of palm oil at 24 ℃ is low, and gel-type egg white powder, edible salt and sour agent are not added into the raw material of comparative example 2, so that the water activity of the prepared roasted sauce reaches 0.92, the pH value is 6.5, microorganism growth and reproduction are easy to cause, the total number of bacterial colonies in the roasted sauce exceeds the standard after 20 days, and the roasted sauce is not suitable for long-term storage at normal temperature. And the weight parts of the palm oil at 24 ℃ in the raw materials are low, gel-type egg white powder is not added, so that the prepared rock-burning sauce is poor in oil wettability and gel property after baking, and the rock-burning sauce is easy to adhere to a packaging bag when being smeared on toast or cake.
As is clear from the raw material formulation of the comparative example 3 and Table 2, the raw materials of the comparative example 3 are not added with full-fat milk powder, carrageenan and gel-type whey protein powder, so that the prepared rock-burned sauce has insufficient gel property, is easy to stick to a bag, has low protein content, lower Maillard reaction degree and lighter color after baking.
As can be seen from the above raw material formulation of comparative example 4 and table 2, the raw materials of comparative example 4 are not added with trehalose, glycerol and sorbitol, so that the water activity of the prepared rock-burning sauce is higher, microorganisms are easy to grow and multiply, and the shelf life of the prepared rock-burning sauce is shorter, and meanwhile, as can be seen from the detection results of comparative example 2 and comparative example 4, although both comparative example 2 and comparative example 4 are added with a certain amount of potassium sorbate and sodium dehydroacetate with antiseptic effect, the water activity of the rock-burning sauce is too high, the microorganisms are easy to grow and multiply, so that the shelf life of the rock-burning sauce is greatly reduced, the pH value of the rock-burning sauce prepared in comparative example 2 is lower than that of comparative example 2, and the shelf life of the rock-burning sauce is 1 month, therefore, the technical scheme can greatly improve the coordinated effect by reducing the water activity and pH value of the rock-burning sauce and adding a small amount of potassium sorbate and sodium dehydroacetate, and the shelf life of the rock-burning sauce can reach the shelf life of 6 months at normal temperature.
The technical principle of the present invention is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in any way as limiting the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
