Description

Preparation method of walnut kernel, sweetened bean milk powder or emulsion combined food

Technical Field

The invention relates to a preparation method of walnut kernel, sweetened bean milk powder or emulsion combined food.

Background

The oil sand bean is a crop which can grow on barren land, contains 25-35% of edible oil, and has higher oil yield than soybean in unit area, and the edible oil contains unsaturated fatty acid higher than soybean oil, rapeseed oil and peanut oil. The sweetened bean also contained 58% protein, with a fat to protein ratio of approximately 3.5: 1; the walnut is not only a high-quality nut, has certain food therapy and health care effects, but also is an important source of edible oil, and the quality of the walnut is close to that of olive oil. The ratio of oil and fat to protein contained in the walnut kernel is approximately 4.6: 1.

The sweetened bean paste or the walnut kernel serving as food materials are directly processed, the oil content is heavier, and although the food is not disturbed when being taken in a small amount each time, if the food is taken excessively, the food can have some adverse effects on intestines and stomach, and even bring a lot of adverse effects. Of course, if the beverage is made, the sweetened bean paste or the walnut kernel is only used as a flavor development substance, the solid content is limited, and the beverage is not influenced even if the beverage is drunk; as a meal replacement food, the sweetened bean or walnut kernel is the source of energy, and the solid content is several times or ten times that of the beverage.

CN202010179553.3 discloses a sweetened bean milk prepared from semen glycines, fresh sweetened bean, white sugar, monoglyceride and diglyceride fatty acid ester, and its preparation method. The sweetened bean milk prepared from the oil sweetened bean is a combination of the oil sweetened bean or the oil sweetened bean pulp and the soybean or the soybean protein powder, overcomes the problem of low protein content of the oil sweetened bean, and is more nutritious than the pure oil sweetened bean. However, this food product does not have the beany flavor of soybeans because of the addition of soybeans.

CN201911380272.8 discloses a walnut milk capable of effectively keeping original flavor and a preparation method thereof. In order to remove the bitter taste of the walnut kernels, the invention adopts a freeze drying method to dehydrate the skins of the walnut kernels, and further peels off the skins manually, so that the process is complex and the efficiency is low; importantly, similar products almost use walnut kernels as raw materials, so that the ratio of grease to protein in the finished product is 4.6:1, and the grease is obviously heavier.

Disclosure of Invention

The invention aims to provide a preparation method of walnut kernel, sweetened bean milk powder or emulsion combined food, which has the advantages of easily controlled flow, simple equipment, novel finished product flavor, fresh scent and sweet taste, rich nutrient substances such as protein, vegetable oil, amylose and the like and suitability for people of all ages.

The purpose of the invention is realized as follows:

the preparation method of the walnut kernel and sweetened bean milk powder combined food comprises the following steps:

1) removing peel and coarse crushing of the sweetened bean paste, and squeezing to obtain sweetened bean paste oil and semi-defatted sweetened bean paste cake;

2) soaking the walnut kernels in 1-5 times of boiled water by weight of the walnut kernels to remove the bitter taste of the walnut kernels, then drying to obtain debitterized and astringent walnut kernels, and squeezing to obtain debitterized and astringent walnut kernel cakes;

3) mixing the semi-defatted sweetened bean paste cake and the debitterized and astringent walnut kernel cake, pulverizing, sieving with 80 mesh sieve, removing walnut kernel skin, sweetened bean residual skin and crude fiber, pulverizing the undersize, and sieving with 100 mesh sieve to obtain mixed fine powder of sweetened bean paste and walnut kernel;

4) adding protein powder and 100-mesh sodium alginate fine powder into the mixed fine powder of the oil sand beans and the walnut kernels, uniformly mixing, and subpackaging to obtain the oil sand beans and walnut kernel milk powder combined food, wherein the weight ratio of the mixed fine powder of the oil sand beans and the walnut kernels to the protein powder to the sodium alginate fine powder is 90-10: 10-90: 0.1-5.

The preparation method of the walnut kernel and sweetened bean paste emulsion combined food comprises the following steps:

1) removing peel and coarse crushing of the sweetened bean paste, squeezing to obtain sweetened bean paste oil and semi-defatted sweetened bean paste cake,

2) soaking the walnut kernel in 1-5 times of boiled water to remove its bitter taste, taking out, squeezing to obtain debitterized and astringent walnut kernel cake,

3) mixing the semi-defatted sweetened bean paste cake and debitterized and astringent semen Juglandis cake, adding water, and grinding in colloid mill repeatedly. Then the mixture is filtered by 200 meshes of filter cloth to obtain slurry,

4) adding protein and sodium alginate into the slurry under the conditions of heating and stirring, finally supplementing clear water to ensure that the weight percentage concentration of the slurry reaches 5-25%, and heating to 100 ℃ to obtain the walnut kernel and sweetened bean paste emulsion combined food.

The preparation method of the walnut kernel and sweetened bean paste emulsion combined food comprises the steps of heating the slurry to 100 ℃, filling and sealing at the temperature of 80-90 ℃ to obtain the walnut kernel and sweetened bean paste emulsion combined food.

The walnut kernel, the sweetened bean milk powder and the milk are products developed by focusing on meal replacement, even certain protein is added into the products, so that the proportion of oil and the protein is further reduced, and simultaneously, the energy substance of minimum unit food is maximized.

The invention reduces the proportion of grease and protein in the food materials by removing part of grease of the fried shaka beans and the walnut kernels, and then adopts a method of adding protein to ensure that the proportion of the grease and the protein is more suitable for the digestion and absorption of intestinal tracts of human bodies, and even if a large amount of grease is ingested, the discomfort of the gastrointestinal tracts can not be caused.

The invention also adopts a simple method of soaking in boiled water to remove the bitter taste of the walnut kernel efficiently and quickly, so that the walnut kernel has natural fresh and sweet taste.

The invention uses mechanical pressing method to remove part of grease. The amount of grease which needs to be removed from the two food materials can be properly adjusted according to the conditions: the oil removed from the sand bean oil accounts for 0 to 95 percent of the total oil content; the total amount of the oil extracted from the walnut kernel is 15 to 99 percent. The regulation principle is that the ratio of oil and protein is kept between 0.7 and 0.8: 1.

The added protein of the invention refers to other edible proteins such as egg white protein, whey protein, peanut protein, pea protein and the like.

The invention has the advantages of easy control of the process, simple equipment, novel flavor of the finished product and suitability for large crowds. Is rich in nutrients such as protein, vegetable oil, amylose and the like, has the fresh sweet taste of the fried sweet bean and the fragrance of the walnut milk, and is suitable for both the old and the young.
