Embodiment 1

[0016] A kind of fern root preparation method, concrete steps are as follows:

[0017] 1. Excavation of fern roots: Before and after frost, when the ground stems and leaves die until February of the following year, dig up the underground rhizomes and wash them with clean water;

[0018] 2. Beating: Send the washed fern root into a beater for beating to obtain fern root pulp;

[0019] 3. Rinse: Wash the fern root slurry with water, and keep stirring, so that the starch is fully suspended in the water and separated from the root dregs;

[0020] 4. Filtration: Filter the starch liquid through a filter with a filter cloth of 90 mesh;

[0021] 5. Sedimentation and separation: the filtered starch suspension is separated by a centrifugal sedimentation separator to obtain primary wet starch;

[0022] 6. Refining: Rinse the primary wet starch with water, stir well and filter through a 200-mesh filter, and the filtrate is separated by a centrifugal sedimentation separator to obtain re...

Abstract

The invention discloses a fern powder preparation method, and belongs to the technical field of food processing. A preparation process comprises the following steps of picking and digging fern roots, pulping, rinsing, filtering, settling and separating, refining and drying. The fern powder preparation method disclosed by the invention has beneficial effects that labor intensity is greatly lowered, and powder yield is improved by 5%-8%; the product is pure-white dry powder, has fresh scent of bracken, no abnormal smell, and has moisture content of less than 7% and silt content less than 0.1.

Description

technical field [0001] The invention relates to food processing, in particular to a method for processing and preparing fern powder, which belongs to the technical field of food processing. Background technique [0002] Fern powder is obtained by processing the starch contained in fern root. "Compendium of Materia Medica" contains: "The root is purple, and there is white powder in the skin. Smash it, wash it again and again, take the powder for sticking in the cabinet, and shake the skin for thread food. The color is light purple and very smooth." Fern powder can be made. Vermicelli and vermicelli can be used to prepare cakes and snacks, and can also replace soybean flour and lotus root flour, with rich nutritional value. The traditional snack "Keqiu Se" in Mingxi County, Fujian Province is made of fern powder as the main ingredient. It tastes delicate and smooth, and has a special flavor. Use 90-120 grams of fern powder, add a little brown sugar, and take it with boiling ...
