Problems solved by technology

[0006] The main component of traditional water chestnut powder skin is only water chestnut starch, which has a single function and does not play a variety of health functions of water chestnuts. In addition, water chestnut starch is a relatively expensive starch, which also leads to higher production of water chestnut powder skin and high market prices. , water chestnuts with multiple nutritional components can not really become a popular food

Embodiment 1

[0039] Embodiment 1 water chestnut vermicelli

[0040] The water chestnut powder skin of the present embodiment, its production method comprises the steps:

[0041] (1) Extraction of flavonoids from water chestnut processing waste

[0042] Take the processing waste from the water chestnut powder skin factory, dry it at 60°C to a solid flake shape, then crush it with a pulverizer, add water 40 times the weight of the crushed material, extract it in warm water at 75°C for 2 hours, and then extract it with microwave for 4 minutes , and the filtrate obtained by filtering is the flavonoids solution;

[0043] (2) Extraction of dietary fiber from water chestnut processing waste

[0044] Dry the above-mentioned flavonoid-extracted waste at 80°C to constant weight, then pulverize it with a pulverizer, and use a high-temperature-resistant α-amylase solution for enzymolysis. The dosage of the enzyme solution is 0.3mL / g. The temperature of hydrolysis is 65°C, and the time of enzymolysi...

Embodiment 2

[0052] Embodiment 2 water chestnut vermicelli

[0053] The water chestnut powder skin of the present embodiment, its production method comprises the steps:

[0054] (1) Extraction of flavonoids from water chestnut processing waste

[0055] Take the processing waste from the water chestnut powder skin factory, dry it at 60°C to a solid flake, then crush it with a pulverizer, add 70% ethanol that accounts for 10 times the mass of the crushed material, extract it in warm water at 75°C for 2 hours, and then microwave it in mid-range Extract for 4 minutes, and filter the obtained filtrate to be the flavonoids solution;

[0056] (2) Extraction of dietary fiber from water chestnut processing waste

[0057] Dry the above-mentioned flavonoid-extracted waste at 80°C to constant weight, then pulverize it with a pulverizer, and use a high-temperature-resistant α-amylase solution for enzymolysis. The dosage of the enzyme solution is 0.3mL / g. The temperature of hydrolysis is 65°C, and th...

Embodiment 3

[0060] The quality of embodiment 1 gained water chestnut vermicelli finished product is compared with existing pure water chestnut vermicelli finished product, as shown in table 1, the stretching force of visible vermicelli has increased by 11.5%, and boiling loss rate has increased 25.0%, and swelling degree reduces The content of flavonoids increased by 8.0%, the content of flavonoids increased by 40mg / 500g, and the dietary fiber increased by 0.1g / g.

[0061] In addition, compared with the production of water chestnut powder skin by the traditional method, the production cost of embodiment 1 can also save 2.24 yuan / jin (the price of potatoes is 5 yuan / jin, sweet potato starch is 4 yuan / jin, cornstarch is 3 yuan / jin, Water chestnut starch is 11 yuan / catties).

[0062] Thereby it can be seen that the process of utilizing waste to produce water chestnut vermicelli in the present invention is not only beneficial to environmental protection, but also realizes waste recycling, and ...

Abstract

The invention discloses a method for producing water chestnut sheet jelly, which comprises the following steps: adding flavone substances and dietary fiber separated and extracted from waste of water chestnut processing into water chestnut starch, corn starch, potato starch and sweet potato starch; stirring the mixture to obtain slurry; and preparing to obtain the water chestnut sheet jelly. The method extracts water chestnut flavones and the dietary fiber from mass processing waste caused by the current water chestnut production to realize waste utilization, and reduces the production cost of the water chestnut sheet jelly by adding accessories such as the corn starch, the potato starch and the sweet potato starch, does not influence the quality of the water chestnut sheet jelly, the content of functional ingredients of the sheet jelly is improved obviously, the stretching force of the water chestnut sheet jelly is increased by 11.5 percent, the boiling loss rate is increased by 25.0 percent, the swelling capacity is reduced by 8.0 percent, the content of flavone compounds is increased by 40mg / 500g, the dietary fiber is increased by 0.1g / g, and the water chestnut sheet jelly has high nutrition and health care values.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a production method of water chestnut powder skin. Background technique [0002] Water chestnut, commonly known as "horseshoe" (scientific name is Water Chestnut or Eleocharis turrosa), is a specialty fruit in my country.
