Description
Technical Field
The invention relates to the field of food processing, in particular to a preparation method of instant castanopsis sclerophylla powder.
Background
Castanopsis sclerophylla named as Castanopsis sclerophylla Kao, Castanopsis sclerophylla tree and Castanopsis mollissima belonging to Fagaceae, belonging to evergreen broad-leaf arbor, is one of the main tree species of subtropical evergreen broad-leaf forest, and is mainly distributed in Jiangxi, Guangdong, Fujian, Sichuan, Yunnan, Hunan, Hubei, etc. The castanopsis sclerophylla fruit is rich in nutritional components such as starch, pectin, vitamins and minerals, wherein the content of starch accounts for more than 48% of the total weight of the fruit. At present, the development and utilization of the castanopsis sclerophylla fruit are not concerned, and the product form is single, mainly comprising castanopsis sclerophylla bean curd, vermicelli and the like. The brewing beverage taking the castanopsis sclerophylla powder as the raw material is not seen in the market.
Instant brewed beverage is popular among consumers due to the characteristics of convenient carrying, transportation, easy storage, convenient eating and the like. The main starch-based reconstituted foods in the market comprise lotus root starch, kudzu root powder, lily powder and the like. Gelatinization of starch usually requires two steps, first a small amount of cold water is used for homogenization and then added to boiling hot water with constant stirring until a transparent starch paste is formed. If the starch is directly mixed with hot water, the starch is easy to agglomerate and conglobate, and the problem of hard core is caused due to incomplete gelatinization. In order to improve the reconstitution property of the product, starch-based instant reconstituted beverages on the market are usually added with ingredients such as sucrose and maltodextrin to improve the dispersibility of the product. However, such products have difficulty meeting the growing health needs of consumers for low-sugar, non-additive foods.

Detailed Description
For better explanation of the present invention, the following detailed description of the present invention is provided for understanding.
The invention discloses a preparation method of instant castanopsis sclerophylla powder, which comprises the following steps:
s1: preparing materials, selecting fresh, rot-free and mildew-free semen Castanopsis Sclerophyllae seeds, and shelling;
s2: pulping, adding 0.2% NaOH solution into the shelled castanopsis sclerophylla seeds, and pulping, wherein the castanopsis sclerophylla seeds: the mass ratio of 0.2% NaOH solution is 1: 2;
s3: the slurry is kept stand for 24 to 48 hours, then precipitate is separated out and washed by water until the pH value is 6.5 to 7.
S4: adding water into the precipitate obtained in the step S3, adjusting the water content to 60-75%, homogenizing, and heating the slurry at 50-65 deg.C for 18-30 h;
s5: drying the castanopsis sclerophylla pulp obtained in the step S4 with hot air at 35-45 deg.C for 24-36 h;
s6: pulverizing the castanopsis sclerophylla powder obtained in step S5, and sieving with 60-100 mesh sieve to obtain instant castanopsis sclerophylla powder.
In step S4, the slurry is heated at 50-65 ℃ for 18-30h, and is carried out in a water bath.
The interactions between starch molecules during starch gelatinization, mainly the effects of hydrogen bonds, are the root cause of the formation of lumps. The interaction between starch molecules can be measured by viscosity, the greater the caking capacity. In the technical scheme, the gelatinization temperature and viscosity of the castanopsis sclerophylla powder are regulated and controlled by a limited water temperature-control heating method, so that the viscosity of the starch is reduced, and the gelatinization temperature corresponding to the peak viscosity is increased, thereby delaying the process of increasing the viscosity of the starch during the brewing and improving the brewing property of the castanopsis sclerophylla starch.
The invention provides a preparation method of instant castanopsis sclerophylla powder. The technical scheme takes the castanopsis sclerophylla powder which is deproteinized and degreased by 0.2 percent NaOH solution as an object, and regulates and controls the gelatinization temperature and the internal lamellar structure of the castanopsis sclerophylla powder by controlling water content, heating temperature and time, thereby controlling the gelatinization and dispersion process of the castanopsis sclerophylla powder in hot water and achieving the instant dissolution effect of uniform dispersion and gelatinization.
The following examples are described with respect to the test methods:
the product was evaluated for reconstitution properties by the following method:
(1) dispersibility
Weighing 10g (dry basis) of a sample, adding 160mL of boiling water into a beaker, mixing into paste, standing for 5min, filtering the mixed solution by using a 100-mesh screen, washing the caking by using clear water, draining, drying at 105 ℃ to constant weight, cooling to room temperature, and weighing. The dispersibility of the product was evaluated thereby. The lighter the filtrate, the better the dispersion, and conversely, the worse the dispersion.
(2) Wettability
Taking part of the filtrate from the filtration operation for measuring dispersibility, heating in boiling water for 20min, and cooling to room temperature. Taking 5ml of cooled paste, diluting by 5 times, and measuring the light transmittance of the paste by using distilled water as a reference to serve as a reference; then, 5mL of the unheated filtrate was diluted 5 times and the light transmittance was measured, and the ratio to the reference was defined as the wettability of the filtrate. The higher the ratio, the better the wettability; conversely, the poorer the wettability.
According to the method, the mixing property of the instant castanopsis sclerophylla powder product is evaluated by using the mixing property score index. The full scale is 100 minutes, wherein the dispersibility is 70 minutes and the wettability is 30 minutes.
Dispersibility of the product (1-block weight of product/sample weight) × 70
Product wettability (sample light transmittance ratio/maximum sample light transmittance ratio) × 30
Reconstitution score-dispersibility score + wettability score
Example 1
(1) Selecting fresh, rotten and mildewless castanopsis sclerophylla seeds, shelling, adding 0.2% NaOH solution according to the mass ratio of 1:2, and pulping.

(5) and (4) crushing the castanopsis sclerophylla powder obtained in the step (4), and sieving the crushed castanopsis sclerophylla powder with a 60-mesh sieve to obtain the instant castanopsis sclerophylla powder.
Table 1 shows the castanopsis sclerophylla powder reconstitution score under different treatment conditions. As can be seen from table 1, the castanopsis sclerophylla powder (examples 2 and 3) has better reconstitution property after the limited moisture temperature-controlled heating step compared with the common castanopsis sclerophylla powder (example 1). And the reconstitution property of the sample obtained in the example 3 is obviously better than that of the sample obtained in the example 2, which shows that the moisture content of the material and the processing temperature have obvious influence on the reconstitution property of the finished product in the limited moisture temperature-controlled heating process. Therefore, the material is required to have the moisture content of 60-75%, the heating temperature of 50-65 ℃ and the heat treatment time of 18-30h in the claims.
