Embodiment 1

[0010] Take 1 kg of fresh konjac corm and add 5 kg of water to mash it for 30 minutes, add sodium carbonate to adjust the pH to 11, put it in a plate and let it stand for 1 hour, steam for 1 hour, after cooling, put it into the freezer at a low temperature of -10 degrees Celsius for 48 Hours, after thawing and dehydrating, use stainless steel mesh clips to compress 50%, bake at 70 degrees Celsius for 2.5 hours, remove the stainless steel mesh clips, and finally cut into pieces and pack according to different sizes.

Embodiment 2

[0012] Take 1 kilogram of konjac flour, add 50 kilograms of water and stir for 30 minutes, add sodium carbonate to adjust the pH to 13, put it in a plate and let it stand for 3 hours, steam for 1.5 hours, and after cooling, put it in a low temperature of -20 degrees Celsius and freeze it for 72 hours , after thawing and dehydrating, use stainless steel mesh clips to compress 40%, bake at 80 degrees Celsius for 3 hours, remove the stainless steel mesh clips, and finally cut into pieces and pack according to different sizes.

Embodiment 3

[0014] Take 1 kilogram of konjac flour, add 30 kilograms of water and stir for 30 minutes, add calcium hydroxide to adjust the pH to 12.5, put it in a plate and let it stand for 2 hours, steam for 2 hours, cool it and put it into a freezer at a low temperature of -30 degrees Celsius for 36 Hours, after thawing and dehydrating, use stainless steel mesh clips to compress 30%, bake at 100 degrees Celsius for 1.5 hours, remove the stainless steel mesh clips, and finally cut into pieces and pack according to different sizes.

Abstract

The invention provides a method for producing compressed konjac snow, comprising the following steps: mashing fresh konjac or adding water into konjac powder for swelling; freezing, unfreezing, dehydrating, and carrying out increased pressure compression drying; and finally dicing and packaging. The volume of the konjac snow product processed by the method in the invention is greatly reduced, the packaging and transporting costs are saved, the shape is uniform, and the appearance of the konjac snow product is good. The konjac snow product is easy to rehydrate before being eaten, which is the same with the traditional product, and no operation procedure is added.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of compressed snow konjac. Background technique [0002] The current snow konjac is divided into two situations: natural production and factory artificial production. The former is to use high-altitude winter low-temperature frozen konjac cakes, and the latter is to artificially freeze konjac cakes in factories. After that, the frozen konjac cakes are artificially or naturally dried. , making it a dried snow konjac product with certain pores. The product has the disadvantages of small specific gravity, large volume, high packaging and transportation costs, and easy deformation during the drying process. Contents of the invention [0003] For above shortcoming, the purpose of this invention is to provide a kind of production method of compressed snow konjac. The method utilizes the flexibility of the snow konjac to compress the snow konjac before it...
