Embodiment 1

[0027] Example 1: This embodiment adopts the mechanical extrusion production method.

[0028] Raw material formula (weight percentage): Eucommia leaf extract 1.5%, sweet potato starch 97.3%, salt 1%, food additive 0.2%, food additive is zinc sulfate (0.004%) and a mixture of sodium polyacrylate and sodium alginate (0.196%) . The weight ratio of sodium polyacrylate and sodium alginate is 1:1-1.5.

[0029] The specific production method is:

[0030] (1) Kneading noodles: Weigh sweet potato starch, eucommia leaf extract, salt, zinc sulfate, sodium polyacrylate and acetate starch in proportion, add warm water and stir. When kneading the dough, the temperature of the warm water is 40°C, and the water content of the kneaded suspension slurry (liquid) is controlled within the range of 48-50%;

[0031] (2) Extrusion aging: the mixed starch suspension is directly extruded by a screw extruder to complete the aging. The starch suspension should be filtered before entering the extrud...

Embodiment 2

[0045] Example 2: Present embodiment is manual production method:

[0046] Raw material formula (percentage by weight): Eucommia ulmoides extract 1.5% eucommia leaf extract, sweet potato starch 97.2%, salt 1%, food additive 0.3%, food additive is a mixture of zinc sulfate (0.004%) and sodium polyacrylate and sodium alginate (0.296%). The weight ratio of sodium polyacrylate and sodium alginate is 1:1-1.5.

[0047] The specific production method is:

[0048] (1) Thickening: Put 0.57kg of sweet potato starch into the tank, add 1kg of 98°C hot water to preheat, stir evenly, it feels smooth and soft, even and transparent, and the paste is made into paste;

[0049] (2) And Gorgon: Add about 9.3kg of sweet potato starch, 150g of eucommia leaf extract, 100g of salt, 0.4g of zinc sulfate, 14.6g of sodium polyacrylate and 15g of sodium alginate to the Gorgon paste, and then add 7.5kg of 50°C Mix warm water in a mixer at 500r / min for 15 minutes to obtain a uniform and delicate dough...

Abstract

The invention discloses eucommia sweet potato powder and a preparation method thereof, wherein the eucommia sweet potato powder is prepared from the following raw materials in percentage by weight: 0.5-2.5% of eucommia leaf extractive, 96.0-98% of sweet potato starch, 0.5-1.2% of edible salt and 0.3-0.6% of food additive, and the eucommia sweet potato powder is prepared by the steps of dough kneading, extruding and curing, aging, freezing, unfreezing and vermicelli dispersing, wherein the eucommia leaf extractive is an alcohol extractive of eucommia leaves; the food additive is one or a mixture of multiple of zinc sulfate, sodium polyacrylate, acetic ester starch and sodium alginate. According to the invention, the eucommia extractive is added, thus the health care value is increased for the traditional food of sweet potato vermicelli, and the special raw material proportion and production technology can effectively maintain the effective components of the eucommia extractive, thus the product has favorable impressions and mouthfeel, has high toughness, is not messy after being cooked for a long time, and also is easier to implement vermicelli dispersing under the condition that harmful substances such as alums are not added.

Description

technical field [0001] The invention relates to the field of food processing, in particular, it provides eucommia sweet potato powder and a production method thereof. Background technique [0002] Eucommia ulmoides is a perennial deciduous tree in the Eucommiaceae genus Eucommia, which is unique to my country. Eucommia bark is a traditional precious Chinese medicinal material, which has the functions of nourishing liver and kidney, strengthening bones and muscles, anti-abortion and lowering blood pressure. In recent years, many studies have shown that the chemical composition of Eucommia leaves and Eucommia bark is basically the same, and they have the same medicinal value. There are many researches on health food made from Eucommia ulmoides, most of which are prepared from Eucommia ulmoides or its extracts and other Chinese herbal medicines, and health foods prepared from eucommia ulmoides and its extracts and traditional foods are rarely reported. The "Dendrobium Pueraria...
