Description
Technical Field
The invention relates to the technical field of potato products, in particular to a potato biscuit and a preparation method thereof.
Background
The potato is an annual herb plant of Solanaceae, also named potato, Chinese yam egg, sweet potato, etc. The apple bread has the advantages of wide growth adaptability, high yield, rich nutrition, dual purposes of grains and vegetables, multiple comprehensive processing purposes and the like, supports thousands of loads of human life, and is called underground apples and second bread. In China, potatoes are mainly eaten by fresh food, and are also used as grains and vegetables, and most of staple production areas are directly eaten as staple food. The potato has comprehensive and rich nutrition and better medicinal value. The traditional Chinese medicine considers that the potato is sweet in taste and neutral in nature, and has the effects of harmonizing the stomach, regulating the middle warmer, tonifying spleen, tonifying qi, strengthening the body, tonifying the kidney, and activating blood circulation to reduce swelling. Can be used for treating dyspepsia, anorexia, habitual constipation, listlessness, muscle and bone injury, chronic gastralgia, toxic materials clearing away, and antiinflammatory effects. According to expert investigation, the principal food of local people is potato, which is called the 'village of longevity' in the world.
With the increasing awareness of health care of people; more and more attention is paid to potatoes and products thereof and industrial application thereof, and products thereof are various and come out endlessly. In China, the current main processing varieties are snacks, starch and vermicelli, and the grade of the product is low. In addition, the processing equipment is backward, the capacity is poor, the process technology is imperfect, the comprehensive utilization rate is low, the added value of the product is low, the nutritive value of the potatoes cannot be fully exerted, and the waste of resources is caused.
Disclosure of Invention
In order to solve the technical problems, aiming at the problems, the invention discloses a potato biscuit which has the advantages of rich nutritional value, low energy, easy digestion and good taste; is suitable for people of more ages, improves the added value of the potato products and has better economic value.
In order to achieve the aim, the invention provides a potato biscuit which comprises raw materials of potato powder, low-gluten wheat flour, konjac flour, resistant dextrin, apple juice, yoghurt, grease, milk powder, dried blueberries and sugar; the feed additive comprises the following raw materials in parts by weight: 100 parts of potato powder, 20-30 parts of low-gluten wheat flour, 15-25 parts of konjac flour, 10-15 parts of resistant dextrin, 20-40 parts of apple juice, 2-4 parts of yoghurt, 2-5 parts of grease, 5-10 parts of milk powder, 2-5 parts of dried blueberries and 10-15 parts of sugar.
Further, the raw materials are mixed according to the following weight parts: 100 parts of potato powder, 20 parts of low-gluten wheat flour, 15 parts of konjac flour, 10 parts of resistant dextrin, 20 parts of apple juice, 2 parts of yoghurt, 2 parts of grease, 5 parts of milk powder, 2 parts of dried blueberries and 10 parts of sugar.
Further, the raw materials are mixed according to the following weight parts: 100 parts of potato powder, 30 parts of low-gluten wheat flour, 25 parts of konjac flour, 15 parts of resistant dextrin, 40 parts of apple juice, 4 parts of yoghurt, 5 parts of grease, 10 parts of milk powder, 5 parts of dried blueberries and 15 parts of saccharides.
Further, the raw materials are mixed according to the following weight parts: 100 parts of potato powder, 25 parts of low-gluten wheat flour, 20 parts of konjac flour, 13 parts of resistant dextrin, 30 parts of apple juice, 3 parts of yoghurt, 3 parts of grease, 8 parts of milk powder, 4 parts of dried blueberries and 12 parts of saccharides.
Further, the oil and fat is lard, the milk powder is defatted milk powder, and the saccharide is white granulated sugar.
Further, the potato flour is potato flakes.
Further, the raw materials for preparing the yoghurt comprise fresh milk, lactic acid bacteria, sorbitol and konjac glucomannan.
Furthermore, the mass ratio of the fresh milk to the lactic acid bacteria to the sorbitol to the konjac glucomannan is 1000:2:3: 1.
The invention provides a preparation method of potato biscuits, which specifically comprises the following steps:
s1, preparing potato powder, low-gluten wheat flour, konjac flour, milk powder, dried blueberries and saccharides according to parts by weight, mixing the potato powder, the low-gluten wheat flour, the konjac powder, the milk powder and the saccharides, and uniformly stirring to obtain a powder mixture for later use;
s2, crushing the dried blueberries; sieving with 8-12 mesh sieve to obtain dried pulverized fructus Myrtilli;
s3, removing cores of the apples, cutting into pieces, putting the apples into a pulping machine, adding a proper amount of water, pulping, and sieving by a 30-40-mesh sieve to obtain apple juice;
s4, mixing the resistant dextrin, the apple juice, the yogurt and the grease, and uniformly stirring to obtain mixed slurry;
s5, mixing the powder mixture, the dried blueberry pieces and the mixed slurry, uniformly stirring and kneading into dough, standing for 1.5-2.5h in an environment with the temperature of 35-45 ℃, and standing for proofing;
s6, stirring the proofed dough in a stirrer at a medium speed for 10-15 minutes, cutting the dough into sections, and placing the sections in a forming machine for compression molding to obtain biscuit blanks;
s7, placing the biscuit blank in an environment with the temperature of 35-45 ℃ again and standing for 25-35 min; and then putting into an oven for baking to obtain a finished product.
