Description
Technical Field
The invention relates to a small tea crisp suitable for hyperglycemia groups and a preparation method thereof, and belongs to the technical field of food baking.
Background
With the increase of caloric intake, the reduction of physical labor and the reduction of labor intensity, the number of hyperglycemia population is remarkably increased, and according to the latest data in 2015 of the international diabetes alliance, the number of global diabetic patients is increased to 4.15 hundred million, while the number of national diabetic patients is as high as 1.096 hundred million. The hyperglycemia population is clinically mainly characterized in that insulin is absolutely insufficient or relatively insufficient, so that the hyperglycemia human body is sensitive to carbohydrate substances, and the blood sugar value is easily aggravated when the hyperglycemia population ingests the carbohydrate substances, so that the dietary food source of the hyperglycemia population is strictly limited to a great extent, and the hyperglycemia can cause complications of multiple tissues and organs such as liver, kidney and the like for a long time, so that the hyperglycemia is not prevented and treated.
The existing research has proved that many natural plant active extracts have the efficacy of reducing blood sugar, the tea is known as 'all disease medicine' from ancient times, and the modern medicine has proved that various functional components in the tea have important influence on human metabolism, such as tea polyphenol, tea polysaccharide and other active substances, and the influence modes comprise a plurality of substances which are used as metabolic conduction substance precursors, metabolic pathway substances, metabolite promoters and the like. The tea active extract is used as a blood sugar regulating factor to be compounded into special dietary raw materials and prepared into a mature food product, so that the blood sugar reducing effect can be achieved, and a green and healthy diet concept is embodied.
Chinese patent application No. CN 20121053759 discloses a health tea for reducing blood sugar and a preparation method thereof, which is prepared by cleaning fresh leaves of sweet potato leaves, mulberry leaves and tea leaves, soaking in electrolyzed water, drying after enzyme deactivation, mixing in proportion, coarse crushing and baking. This application has only carried out conventional processing to tealeaves, and the utilization degree is not high, and this kind of utilization mode can't satisfy popular taste and flavor demand.
Chinese patent application No. CN2013101355533 discloses a hypoglycemic tea rice porridge containing rehmannia and a preparation method thereof, the hypoglycemic tea rice porridge is prepared from glutinous rice, large yellow rice, green tea, red sorghum, gordon euryale seed, small red bean, rehmannia, pumpkin leaf, mulberry leaf, coptis chinensis, pineapple, apple, calcium fruit leaf, momordica grosvenori leaf and white granulated sugar in a proper amount, and has the special fragrance of tea leaves, and is delicious and tasty. However, the content of the effective components is low, and the beneficial effect is not judged well.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide the small tea crisp suitable for hyperglycemia groups and the preparation method thereof, which have the advantages that the slowly digestible starch and the tea product are reasonably matched, so that the small tea crisp has good mouthfeel, has the function of regulating blood sugar, enriches the product categories of two substances and has the function.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a small tea crisp suitable for hyperglycemia groups comprises the following baking main materials in parts by weight: 20-30 parts of slowly digestible starch, 5-10 parts of weak flour, 5-10 parts of wheat gluten, 5-10 parts of powdered sugar, 15-25 parts of butter, 1-5 parts of egg yolk and 0.5-1.5 parts of tea products. The addition of the wheat gluten can improve the baking characteristics of the mixed flour and help the mixed flour to form a better network structure.

The raw materials or the equipment are not indicated by manufacturers, and are regarded as conventional products which can be purchased in the market.
According to the small tea crisp suitable for hyperglycemia groups, the main raw material selection is that the weak flour of the common small crisp is replaced by the compound powder of slowly digestible starch, vital gluten and weak flour. The slowly digestible starch can maintain the postprandial blood sugar steady state, improve the glucose tolerance, reduce the postprandial insulin secretion and improve the sensitivity of the body to the insulin, and is an ideal raw material of medicinal and edible food. However, starting from a crisp product, the addition of slowly digestible starch reduces the gluten content of the flour, weakens the formation of a gluten network in the dough, and results in a baked product with poor baking characteristics. The wheat gluten is supplemented according to the proportion of each main component in the flour to form the compound mixed powder, the composition proportion of the main components in the flour is basically maintained, the baking characteristic of the crisp cake is ensured, and the nutritional status of the product can be improved.
When kneading a small crisp dough, tea products are added into mixed powder of slowly digestible starch, low gluten flour and vital gluten in proportion, the tea products comprise tea polyphenol, catechin, tea extract and the like, experiments show that the gelatinization temperature of the starch can be obviously reduced after the tea products are added, and by taking the tea polyphenol as an example, the tea polyphenol is suspected to contain a large amount of polyhydroxy structures, can be combined with side chains of amylopectin and bonded to amorphous areas of starch granules to different degrees, so that the coupling force of the microcrystalline areas and the amorphous areas is changed, the starch granules are easier to hydrate, and the gelatinization can be realized by needing little energy, therefore, the tea polyphenol is added into the mixed powder, and the gelatinization temperature of the starch in the mixed powder can be obviously reduced.

All subjects were fasted from the late meal of the day before the experiment to the early day of the experiment (10-14 h total), venous blood was taken from the finger on an empty stomach, the blood glucose concentration before eating was determined, the snack samples were taken at 50g and the meal was completed within 15min, the time was calculated from the start of the meal, and venous blood was taken from the finger 40min after the meal to determine the blood glucose concentration. The measured blood glucose value after 40min minus the fasting blood glucose value is used as the blood glucose increase index, the average value of each group is taken, and the measured result is shown in table 1. As can be seen from Table 1, the blood sugar increase value of the edible tea product is obviously lower than that of the control group product, so that the tea crisp cake has the function of obviously regulating blood sugar.
TABLE 1 dietary tea set of bars and bar blood glucose changes
| Grouping | 1 | 2 | 3 | 4 | 5 | 6 |
| Blood glucose rise | 0 | 0 | 0.3±0.002 | 0.35±0.004 | 1.35±0.018 | 1.41±0.024 |
2. The tea cookies of the invention are subjected to sensory evaluation, 30 persons are randomly selected as evaluation personnel, the cookies are evaluated in 5 aspects of color, shape, tissue structure, smell and taste identification and acceptance degree, the full score is 10, and the evaluation results are shown in table 2.
TABLE 2 sensory evaluation results
As can be seen from the above table, the overall acceptability, shape, flavor and texture of the tea crisps were rated slightly higher than the control group, but the color was rated slightly lower than the control group.
