Embodiment 1

[0037] According to the mass ratio, take 1 part of konjac, 0.04 parts of sodium carbonate, 0.0325 parts of foaming agent (including 0.0075 parts of potassium hydrogen tartrate, 0.025 parts of sodium bicarbonate), crush and grind, add 10 parts of hot water at 50 °C, and mix quickly. Stir well until the dough becomes gelatinous. Divide the dough-like gel into molds, place in a steam cabinet and steam at 100°C for 1 hour to foam. The foamed gel block slices can be used as konjac foamed food raw materials.

Embodiment 2

[0039] According to the mass ratio, take 1 part of konjac, 0.016 part of sodium carbonate, 0.031 part of foaming agent (including 0.004 part of lactic acid, 0.027 part of ammonium bicarbonate), crush and grind, add 12 parts of hot water at about 50 °C and 0.25 part of ethanol, Mix quickly and stir well until dough-like gel. Divide the dough-like gel into molds, place in a steam cabinet and steam at 110°C for 2 hours to foam. The foamed gel block slices are soaked in clear water to dealkalize, and are used as konjac foaming food raw materials.

Embodiment 3

[0041] According to the mass ratio, take 1 part of konjac, 0.02 parts of sodium carbonate, 0.043 parts of foaming agent (0.017 parts of aluminum sulfate, 0.026 parts of ammonium bicarbonate), crush and grind, add 10 parts of 50 ℃ hot water, and mix quickly. Stir well until the dough becomes gelatinous. Divide the dough-like gel into molds, place in a steam cabinet and steam at 110°C for 1 hour to foam. The foamed gel blocks were frozen at -25°C for 24 hours and then thawed naturally. The water is removed by a drying machine, and dried in a drying room below 60°C to obtain a dried konjac foam product, which is used as a raw material for konjac foam food.

Abstract

The invention provides a konjak foaming composition, its preparation method and application. The composition is mainly prepared from konjak powder, a gelling agent, a foaming agent and water, or is also added with a regulator, an impregnating agent and a surface active agent. The preparation method includes: preparing konjak, the gelling agent, the foaming agent, the regulator, the impregnating agent, the surface active agent and water into a gel, and carrying out steam foaming curing, freezing shaping, demoulding, dehydration, bleaching, drying and other series processes, thus obtaining a konjak foaming food and a konjak sponge product. Due to the employment of chemical foaming in the invention, the konjak sponge can be looser and more elastic.

Description

technical field [0001] The invention relates to a konjac foaming composition and its preparation method and application. The konjac foaming composition is suitable for making konjac foaming food and konjac sponge products. Background technique [0002] In konjac food, snow konjac is a kind of food with holes similar to roasted bran, which is made by mixing konjac flour and other food raw materials with water, steaming and freezing for a long time, and then drying. In this process, the amount of snow konjac and konjac is less than 50%, and the formation of internal pores mainly comes from long-term freezing and the ratio of food raw materials. [0003] The preparation of sponge-like materials from konjac was first seen in the 1990s. Traditional beauty and skin care sponges are mostly made of chemical raw materials through chemical methods. The production process of this kind of sponge is complicated and seriously pollutes the environment. Due to the use of chemical raw m...
