Thereby enabling to recover heat better and saving energy.
Example 2
This example provides a corn silk slurry, which was prepared using the preparation process of example 1. The corn silk slurry in the implementation can better keep the effective components and the flavor of the corn silk.
Example 3
Based on the corn silk slurry of example 2, this example provides a corn silk slurry preparation made by mixing the corn silk slurry of example 2 with cereal and or legume slurry.
The cereal and/or bean slurry described in this embodiment can be red bean juice, green bean juice, rice juice, corn juice, etc.
The preparation in the embodiment is a finished liquid beverage, and the corn stigma slurry in the embodiment 2 and the preparation are mixed according to the weight ratio of 1: 2-1: 10, and then are subjected to high-temperature sterilization and packaging to obtain the corn stigma slurry.
Example 4
This example also provides a corn silk slurry preparation based on the corn silk slurry of example 2, which differs from example 3 in that the preparation in this example is a solid preparation.
In this example, the corn silk slurry preparation is described in detail by taking black beans as an example of the formulation.
The black beans in the embodiment are dry mature seeds of black beans of leguminous plants, and the black beans are recorded in Chinese pharmacopoeia (2015 edition), are sweet and flat, enter spleen and kidney channels, have the effects of improving eyesight, nourishing blood, dispelling wind, inducing diuresis, detoxifying and the like, and have the health-care functions of reducing blood fat, lowering blood pressure, inducing diuresis and the like as proved by modern pharmacological research. The corn stigma is a style and a stigma of gramineous plant corn, recorded in Chinese medicine dictionary (2006 edition), the corn stigma has sweet, light and flat properties, enters kidney, stomach and liver and gallbladder meridians, has the effects of inducing diuresis to reduce edema, clearing liver and benefiting gallbladder and the like, is mainly used for treating edema stranguria, hypertension and the like, and is proved by modern pharmacological research to be capable of reducing blood fat and blood pressure and treating gout.
The corn stigma and the black beans have tropism in nature, taste and meridian tropism in traditional Chinese medicine, and have the functions of reducing blood fat and blood pressure, promoting urination and the like. The two medicines are common traditional Chinese medicines, have mild and non-intense properties and long-term eating history, and are typical plants used as both medicine and food, so that the two medicines are mutually used for preparing health-care food in the embodiment, the medicine effect is enhanced, and the safety of the food is ensured. In addition, the black bean planting in south China mostly uses intercrops as the main, particularly, the intercropping and popularization area of corn and black bean is the largest, the accumulated popularization area reaches more than 2000 ten thousand mu in the places such as Chongqing, Yunnan, Guizhou, Guangxi and the like, and the production area of interplanted edible soybeans in south China is listed as one of three major production areas of ministers in China in the twelfth five-year planning of the national planting development by the Ministry of agriculture, and key construction support is provided, so that corn stigma and black bean are easy to collect, and the source of raw materials is guaranteed.
The preparation in this example was obtained by the following steps in sequence:
step A, removing impurities from black beans, rinsing, completely soaking the black beans in the corn stigma slurry obtained in the example 2 for 2-3 hours, taking out the black beans and draining;
b, baking the black beans treated in the step A for 15-20 minutes in an environment of 100-150 ℃;
and C, mixing and crushing the black beans processed in the step B and the dried corn stigma, and weighing and bagging.
The black bean has strong bitter and wet taste because of the high flavonoid content. In this embodiment, the content of the isoflavone symbols in the black soybean can be significantly reduced by the step a, so that the taste of the black soybean can be improved. Meanwhile, the fragrance of the soybean protein in the black beans can be fully prepared through the step B. Through the step C, the final preparation can have the effective components and the mouthfeel of the black beans and the corn stigma. The black bean water extract has a muddy soup color, the corn stigma water extract has a light yellow and flat soup color, and the black bean water extract and the corn stigma water extract are matched to have a yellow green soup color and are clear and transparent.
The preparation in the embodiment can be taken with boiled water when being eaten, so that the preparation can be taken immediately after being drunk. Thereby facilitating long-term storage.
In the step C of this embodiment, the black beans and the corn stigma can be mixed according to a weight ratio of 3: 1-6: 1. The proportion can obviously reduce the content of the soybean isoflavone aglycone in the black beans and can realize the optimal matching of the taste and the efficacy of the black beans.
In this example, the prepared corn stigma black soybean preparation was subjected to component detection, and the detection result was compared with that of a general roasted black soybean. The isoflavone aglycone (E type) content of the corn stigma black bean preparation prepared in the embodiment with strong bitter taste is obviously reduced compared with that of the baked black bean tea, namely the bitter taste in the preparation is effectively improved.
In addition, in order to verify the influence of the ratio of the black beans to the corn stigma on the quality of the final preparation, the preparations with different ratios are taken for scoring.
In this example, 3g of each of the preparations 1 to 5 of the black beans and the corn stigma in the step C in the weight ratio of 2:1, 3:1, 4.5:1, 6:1 and 7:1, respectively, was added with 300ml of 85 ℃ boiled water and then brewed for 3 minutes, and then evaluated, as shown in table 1 below.
TABLE 1
Figure BDA0002589347410000131
In the table above, the evaluation items are divided into 3 items, namely soup color, aroma and taste, the soup color scoring coefficient is 20%, the aroma scoring coefficient is 35%, and the taste scoring coefficient is 45%, and the final score is obtained by multiplying the score of each item by the coefficient and then adding the multiplied values.
As can be seen from Table 1, the black soybean and corn stigma have better effect when the weight ratio of the black soybean to the corn stigma is 3: 1-6: 1.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
