Problems solved by technology

For example, snow konjac, the existing snow konjac, is generally fresh and spicy, but the elasticity is not good, there is no chewiness, and the taste is single
[0004] And adopt existing konjac fine powder, because production technology difficulty, general purity is relatively low, is unfavorable for the solidification of konjac tofu, makes the time of preparing konjac tofu longer, and production cost is higher, if adopt artificial handsome selection particle size uniform, and Fine konjac powder, discard the larger konjac powder, which makes the waste of raw materials

Abstract

The invention discloses a processing method of snow konjac snack food, which comprises the following steps: 1) preparing konjac powder; 2) preparing konjac tofu; 3) preparing snow konjac; 4) centrifugal dehydration; 5) marinating ; 6), ingredients; 7) packaging and sterilization. The purpose of the present invention is to provide a processing method of snow konjac leisure food. Through a specific process, the snow konjac can not only be solidified into a ball, will not disperse, has good taste, but also has high elasticity and is suitable for the taste of the public.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a processing method of snow konjac snack food. Background technique [0002] Konjac, also known as grinding taro and konjac, is a perennial herbaceous plant of the angiosperm, monocotyledonous plant, araceae, subfamily, and family of acronyms. [0003] There are many kinds of konjac snacks made at present. For example, snow konjac, the existing snow konjac, is generally fresh and spicy, but the elasticity is not good, there is no chewiness, and the taste is single. [0004] And adopt existing konjac fine powder, because production technology difficulty, general purity is relatively low, is unfavorable for the solidification of konjac tofu, makes the time of preparing konjac tofu longer, and production cost is higher, if adopt artificial handsome selection particle size uniform, and Fine konjac powder, discard the larger particle konjac powder, so that the waste of raw...
