Description
Technical Field
The invention relates to the technical field of health-care drinks. More specifically, the invention relates to instant health-care sweet corn flour and a preparation method thereof.
Background
Sweet corn (Sweet corn) is a kind of corn, also called vegetable corn, gramineae, zea. Sweet corn is rich in nutrition, has the characteristics of sweetness, freshness, crispness, tenderness and the like, is deeply favored by consumers of all levels, and is one of the main vegetables in developed countries such as Europe, America, Korea, Japan and the like. The sweet corn industry starts late in China, processing industries such as canned sweet corn, quick-frozen fresh clusters and the like appear from the 20 th century and the 80 th century, and as the living standard of people in China develops from a saturated type to a comfortable and rich type, sweet corn products which are good in eating and nutritious are more and more favored by consumers, and the demand of sweet corn series products is gradually increased.
At present, sweet corn products mainly comprise cans, beverages, corn kernels, sauces, wines and the like, are rich and various in variety, but the powdery products are easier to store and carry and are also very convenient to eat. At present, corn is used for more starch products in auxiliary materials for food and beverage, but instant corn products are fewer and are less commercially available. Because the corn flour has high starch content and fine particles, the corn flour is easy to agglomerate, stick to walls and dissolve slowly during brewing, in order to solve the problem, most instant corn flour products are subjected to puffing and granulating treatment, or dispersing agents are added, even part of corn residue components are removed by filtering, so that the processing process is complicated, the nutrition is lost, the additives are more, and the taste and the flavor are poorer.
The daylily, a perennial herb of hemerocallis in liliaceae, also known as nepenthes, golden lily, lemon hemerocallis, hemerocallis citrina baroni and the like, has edible flower buds, has rich nutritional value, has multiple functions of resisting depression, improving sleep, inducing lactation and the like, but has a single eating method, is generally used for processing specific vegetable products, and has relatively few daylily on a dining table because many people do not like the taste of the daylily.
Under the background environment of modern high-call environmental protection, health, safety and health care, the functional food is more and more popular, so that the research and development of the instant health-care corn flour with the functions of resisting depression, improving sleep and stopping milk has wide market prospect.

Comparative example 1:
an instant health-care sweet corn flour comprises the following raw materials in parts by weight: 25 parts of sweet corn kernels and 1.5 parts of day lily.
The preparation method comprises the following steps:
1) peeling sweet corn, blanching to inactivate enzyme, cooling, centrifuging to dewater, drying at low temperature, grinding with micro powder of 300 mesh to obtain corn powder;
2) decocting flos Hemerocallis for 8-10min, dewatering, drying, and pulverizing to obtain flos Hemerocallis powder;
3) mixing the corn flour and the daylily powder to obtain the instant health-care sweet corn flour.
In order to illustrate the beneficial effects of the instant health-care corn flour, the inventor of the invention tests the instant health-care corn flour according to the instant solubility and the mouthfeel and efficacy of the product, and the specific method is as follows:
experiment I, aiming at the instant health-care sweet corn flour prepared in examples 1-6 and comparative example 1, the sweet corn flour is brewed by using boiling water, the consumption of the sweet corn flour is the same as that of the boiling water, the container and the stirring spoon used for brewing are also the same, the sweet corn flour is brewed by the same person, the dissolution state of the sweet corn flour within 5 seconds after brewing and the taste sense after uniform stirring are counted, and the result is shown in Table 1.
TABLE 1 dissolution status and mouthfeel of sweet corn flour prepared by different implementation methods
As can be seen from Table 1, the corn flours prepared in examples 4-6 have good instant properties, no grainy feel, soft mouthfeel, and good palatability. The instant health-care sweet corn flour in the comparative example 1 is obtained by mixing the corn flour obtained by drying and crushing and the day lily powder, the raw materials are fully utilized, but the taste is poor, and the appearance shape of the corn flour product prepared by brewing is poor.
Experiment II, the inventor carries out effect statistics on the corn flour prepared by the methods of examples 3-6 and comparative example 1 after the corn flour is eaten by the puerpera suffering from mild depression, specifically, the degree of depression, the sleep condition and the milk quantity of the puerpera after the puerpera insists on eating for 1 month (1 time per day), and the specific results are shown in a table 2.
TABLE 2 edible effect of sweet corn flour made according to various embodiments
It can be seen from table 2 that the depression condition can be improved by eating daylily, but many consumers do not like to eat daylily, if like comparative example 1, daylily is directly and completely added into corn flour to prepare an instant product, the mouth feel is poor, the instant property is poor, and the purchase is not directly caused by consumers, if common twice-decoction filtrate is adopted and is combined into corn steep liquor, the depression condition of the finally prepared corn flour is improved slightly after long-term eating, and the sleep and milk amount are not improved obviously, as in example 3, but the daylily extract prepared by the method of example 5 has the advantages that the depression condition of the puerpera is obviously improved after long-term eating, the sleep and milk amount are also greatly improved, and example 6 adds mangosteen auxiliary liquid on the basis of example 5, the depression of the puerpera is basically eliminated after long-term eating the final product, and the sleep quality is obviously improved, the milk quantity is also greatly increased.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
