Abstract

The invention relates to a processing process of a red bud taro powder, comprising the following steps of: selecting materials, finishing, cutting the material into blocks, protecting color, blanching, cleaning, grinding, pulping, homogenizing, drying and collecting. The particular steps are as follows: soaking the cut blocks with 0.1 percent sodium metabisulfite and 0.1 percent citric acid for protecting color, then blanching at 80 DEG C for 1 minutes, taking the blocks out and still soaking the blocks in the color protecting liquid, rinsing the blocks after the temperature is reduced to normal temperature, and washing to remove the remained color protecting liquid. With the adoption of the processing process of the red bud taro powder, the produced taro powder has white color and high quality without brown stain, gelatinization, or conglutination.

Description

A kind of processing technology of taro with red buds taro powder

Technical field

The present invention relates to processing of farm products field, be specifically related to a kind of processing technology of taro with red buds taro powder.

Background technology

Taro with red buds is that taro belongs to Araeceae herbaceos perennial, with the vegetables that bulb taro in underground is main cutting, its edible part bulb is rich in starch, crude fibre, crude fat, protein, VC, calcium, phosphorus, iron, it is treasure in taro, vegetables or staple food can be made, there is nuisanceless, the advantage such as output is high, commodity value is high, storage tolerance.Along with Planter industry structure adjustment and people are to the demand of pollution-free vegetable and diversification of varieties, the personal value of taro with red buds also improves relatively, and gain great popularity after the taro listing of particularly high-quality, anti-season, be easy-to-sell goods well sold and in short supply on domestic and international market always.

Taro with red buds taro powder instant and the preservation time longer, be subject to popular liking always, however produce without brown stain, without gelatinization, without adhesion, color is pure white, the high taro with red buds taro powder of product quality is but and be not easy.

Summary of the invention

The object of this invention is to provide a kind of edible quality, organoleptic quality is excellent, and without brown stain, without gelatinization, without adhesion, color is pure white, the processing technology of the taro with red buds taro powder that product quality is high.

For achieving the above object, the invention provides following technical scheme:

A kind of processing technology of taro with red buds taro powder, this technique comprises following steps: first selection, select high spherical, the fresh taro with red buds taro of substance more than 180 grams, finishing taro, cut root coarse part, soak with 0.1% sodium pyrosulfite and 0.1% citric acid after stripping and slicing and protect look, then blanching 1 minute at 80 DEG C, still be immersed in colour protecting liquid after picking up, be down to after normal temperature with water rinse until material temperature, wash away residual colour protecting liquid, subsequently taro meal is broken into 4-6 mm granules, send into defibrination in fiberizer, taro crude fibre is separated by 100 mesh sieve, part screenings optionally can be got back in defibrination and reprocess, separated taro slurry enters homogeneous in high pressure homogenizer, pressure 20-30 MPa, then spraying dry, EAT 140 DEG C-180 DEG C, leaving air temp 80 DEG C-100 DEG C, atomizer rotating speed 15000-30000 rev/min, finally collect taro powder heat sealed package.

Beneficial effect of the present invention: the taro powder that the processing technology of a kind of taro with red buds taro powder provided by the invention is produced is without brown stain, without gelatinization, without adhesion, color is pure white, and product quality is high.

Detailed description of the invention

Be described step of the present invention and feature below, example, only for explaining the present invention, is not intended to limit scope of the present invention.

Embodiment 1

Select high spherical, the fresh taro with red buds taro of substance more than 180 grams, finishing taro, cut root coarse part, soak with 0.1% sodium pyrosulfite and 0.1% citric acid after stripping and slicing and protect look, then blanching 1 minute at 80 DEG C, still be immersed in colour protecting liquid after picking up, be down to after normal temperature with water rinse until material temperature, wash away residual colour protecting liquid, subsequently taro meal is broken into 4 mm granules, send into defibrination in fiberizer, taro crude fibre is separated by 100 mesh sieve, part screenings optionally can be got back in defibrination and reprocess, separated taro slurry enters homogeneous in high pressure homogenizer, pressure 25 MPa, then spraying dry, EAT 160 DEG C, leaving air temp 90 DEG C, atomizer rotating speed 25000 revs/min, finally collect taro powder heat sealed package.

Embodiment 2

Select high spherical, the fresh taro with red buds taro of substance more than 180 grams, finishing taro, cut root coarse part, soak with 0.1% sodium pyrosulfite and 0.1% citric acid after stripping and slicing and protect look, then blanching 1 minute at 80 DEG C, still be immersed in colour protecting liquid after picking up, be down to after normal temperature with water rinse until material temperature, wash away residual colour protecting liquid, subsequently taro meal is broken into 6 mm granules, send into defibrination in fiberizer, taro crude fibre is separated by 100 mesh sieve, part screenings optionally can be got back in defibrination and reprocess, separated taro slurry enters homogeneous in high pressure homogenizer, pressure 30 MPa, then spraying dry, EAT 180 DEG C, leaving air temp 100 DEG C, atomizer rotating speed 20000 revs/min, finally collect taro powder heat sealed package.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
