Abstract
The invention discloses a method for producing black potato starch by utilizing biological degeneration and relates to a method for processing modified starch. The technical problem that a method for producing the black potato starch by adopting a biological degeneration process does not exist at present is solved. The method comprises the specific steps: (1) preparing raw materials, namely removing stone, soil, wood and grass sundries, cleaning and shredding; (2) adding an enzyme preparation, namely spraying an amylase agent on the materials; (3) performing poikilothermic treatment, namely performing the poikilothermic treatment between normal temperature and 15 DEG C below zero; and (4) performing conventional processing, namely grinding, extracting, concentrating, removing sand, refining, dehydrating, drying, packaging finished products and performing other conventional processing links after the color of the materials is completely black. According to the black potato starch produced by adopting the biological degeneration process, the varieties of starch are increased, the starch quality is improved, and the application range of potato processing is widened.
Description
Technical field
The invention belongs to technical field of agricultural product process, relate to the processing method of converted starch, particularly a kind of processing technology utilizing biological degeneration to produce potato black starch.
Background technology
Farina viscosity is high, good water absorption, thus in food industry applications, occupies significant proportion.Along with the development of modern food industry, simple potato ative starch oneself be difficult to the requirement meeting multi items, contribute to converted starch and meet rigors to raw-food material.
Biological degeneration starch utilizes biological degeneration to change the natural characteristic of starch, makes it be more suitable for the requirement of certain food.This on the basis of normal starch production technology through again processing, change the starch of starch property, be referred to as biological degeneration starch.
Along with the development of converted starch industrial technology, be that the converted starch purposes of raw material is more and more wider with farina.The black starch of potato, owing to having unique nutritive value, under the trend that current pursuit is healthy, enjoys the favor of people.
Existing potato black starch-based product, normally by obtaining true qualities plant processing such as black potato, black taro, black cassavas, also has employing to produce the dyeing of normal potato white starch.The former raw material sources are limited, and range of application is little, and the latter adds coloring agent affects nutritive value.
Summary of the invention
Object of the present invention is intended to the shortcoming overcoming prior art, provides a kind of method utilizing biological degeneration to produce the black starch of potato, and solve and adopt the black starch of true qualities plant processing potato to limit to by raw material sources at present, range of application is little; Adopting dyes produces the black starch of potato affects nutritive value problem because adding coloring agent.
The object of the invention is to be achieved through the following technical solutions:
Utilize biological degeneration to produce a method for the black starch of potato, it is characterized in that: the concrete steps of described method are:
The first step: raw material prepares:
To raw potatoes selection, remove stone, soil, wood, careless foreign material, cleaning;
Second step: add enzyme preparation:
The potato cleaned carries out chopping or section, acid adjustment alkali pH value to 7, sprays material (potato chopping or section) with amylase agent;
3rd step: intermittent warming:
After described material stirring is even, between normal temperature and subzero 15 degree Celsius, carry out intermittent warming;
4th step: conventional machining:
After the complete blackening of described material color and luster, enter traditional machining processes links such as frustrating mill, extraction, concentrated, desanding, refining, dehydration, drying, finished product packing.
Further, described second step: add enzyme preparation, is the amylase agent that is 10000:0.1 with the weight proportion of described material and described amylase agent, sprays described material.
Further, described 3rd step: intermittent warming, is between normal temperature and subzero 15 degree Celsius, carries out twice intermittent warming, be down to subzero 15 degree Celsius by described material by normal temperature, then thaw to normal temperature by subzero 15 degree Celsius, repeat once with this; Want lucifuge during cooling, will assist with illumination and ventilation when thawing.
Further, described illumination is sunlight, may also be the illumination of 100LUX illumination, 4000K colour temperature; The wind speed of described ventilation is 4m/s.
Further, when thawing described in, material at least will stir once.
The present invention compared with prior art, the principle that enzyme swashs brown stain is produced owing to utilizing amylase, between subzero 15 degree to normal temperature amplitude, alternating temperature controls, the activity of enzyme is made constantly to activate, constantly act on, supplement with illumination and air-supply again, enzymatic browning is fully formed, this black modified potato starch utilizing biological degeneration obtained, brown pigment significantly improves, and makes starch have unique nutritive value and application space.
The present invention utilizes the black starch of the potato of biological degeneration explained hereafter, adds starch varieties, improves starch quality, has widened the application of Potato ring rot bacteria.
Detailed description of the invention
Embody the exemplary embodiments of feature & benefits of the present invention, will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from protection scope of the present invention, and explanation is wherein the use when explaining in itself, and is not used to limit the present invention.
Utilize biological degeneration to produce a method for the black starch of potato, its concrete processing step is:
The first step: raw material prepares:
To raw potatoes selection, remove stone, soil, wood, careless foreign material, cleaning;
Second step: add enzyme preparation:
The potato cleaned carries out chopping or section, acid adjustment alkali pH value to 7, sprays material (potato chopping or section) with amylase agent;
3rd step: intermittent warming:
Described material stirring evenly after, at normal temperature (as 10 degree to 15 degree Celsius Celsius) with between subzero 15 degree Celsius, carry out intermittent warming;
4th step: conventional machining:
After the complete blackening of described material color and luster, enter traditional machining processes links such as frustrating mill, extraction, concentrated, desanding, refining, dehydration, drying, finished product packing.
Described second step: add enzyme preparation, is the amylase agent that is 10000:0.1 with the weight proportion of described material and described amylase agent, sprays described material.
Described 3rd step: intermittent warming, at normal temperature (as 10 degree to 15 degree Celsius Celsius) with between subzero 15 degree Celsius, carry out twice intermittent warming, subzero 15 degree Celsius are down to by 10 degree Celsius by described material, thaw to 10 degree Celsius by subzero 15 degree Celsius again, repeat once with this; Or described material is down to subzero 15 degree Celsius by 15 degree Celsius, then thaw to 15 degree Celsius by subzero 15 degree Celsius, repeat once with this.Want lucifuge during cooling, will sunlight be aided with when thawing and ventilate (wind speed is 4m/s); Also 100LUX illumination, the illumination of 4000K colour temperature ventilate (wind speed is 4m/s) can be aided with when thawing.
