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 of utilizing biological degeneration to produce potato black starch.
Background technology
Farina viscosity is high, good water absorption, thereby in food industry applications, occupies significant proportion.Along with the development of modern food industry, oneself is difficult to meet the requirement of many kinds simple potato ative starch, contributes to converted starch to meet the harsh requirement to raw-food material.
Biological degeneration starch is to utilize biological degeneration to change the natural characteristic of starch, makes it be more suitable for the requirement in specific food products.This on the basis of conventional starch producing technology through processing again, changed the starch of starch property, be referred to as biological degeneration starch.
Along with the development of converted starch industrial technology, the converted starch purposes that the farina of take is raw material is more and more wider.The black starch of potato, owing to having unique nutritive value, is pursued under healthy trend current, enjoys people's favor.
Existing potato black starch-based product, normally by the true qualities plant processing such as black potato, black taro, black cassava are obtained, dyeing is produced to common potato white starch also employing.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 overcome the shortcoming of prior art, and a kind of method of utilizing biological degeneration to produce the black starch of potato is provided, and solves and adopts at present the black starch of true qualities plant processing potato limited to by raw material sources, and range of application is little; Adopt dyeing to produce the black starch of potato and because adding coloring agent, affect the problem of nutritive value.
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 is prepared:
To raw potatoes selection, remove stone, soil, wood, careless foreign material, clean;
Second step: add enzyme preparation:
The potato that cleaning completes carries out chopping or section, and acid adjustment alkali pH value to 7 sprays material (potato chopping or section) with amylase agent;
The 3rd step: alternating temperature is processed:
After described material stirring is even, between normal temperature and subzero 15 degree Celsius, carry out alternating temperature processing;
The 4th step: conventional machining:
After the complete blackening of described material color and luster, enter conventional machining process procedures such as frustrating mill, extraction, concentrated, desanding, refining, dehydration, dry, finished product packing.
Further, described second step: adding enzyme preparation, is to take the amylase agent that the weight proportion of described material and described amylase agent is 10000:0.1, sprays described material.
Further, described the 3rd step: alternating temperature is processed, is between normal temperature and subzero 15 degree Celsius, carries out twice alternating temperature processing, is about to described material and is down to subzero 15 degree Celsius by normal temperature, then thawed to normal temperature by subzero 15 degree Celsius, with this, repeats once; During cooling, want lucifuge, while thawing, will assist with illumination and ventilation.
Further, described illumination is solar light irradiation, also the illumination of 100LUX illumination, 4000K colour temperature; The wind speed of described ventilation is 4m/s.
While thawing further,, material at least will stir once.
The present invention compared with prior art, owing to utilizing amylase to produce the principle that enzyme swashs brown stain, subzero 15, spend to alternating temperature control between normal temperature amplitude, the activity of enzyme is constantly activated, constantly act on, supplement with illumination and air-supply again, enzymatic browning is completed into, this black modified potato starch that utilizes biological degeneration to make, brown pigment obviously 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, has increased starch kind, has improved starch quality, has widened the application of potato processing.
The specific embodiment
The exemplary embodiments that embodies feature & benefits of the present invention, will describe in detail in the following description.Be understood that the present invention can have various variations on different embodiment, it neither departs from protection scope of the present invention, and explanation is wherein when the use that explain in itself, but not in order 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 is prepared:
To raw potatoes selection, remove stone, soil, wood, careless foreign material, clean;
Second step: add enzyme preparation:
The potato that cleaning completes carries out chopping or section, and acid adjustment alkali pH value to 7 sprays material (potato chopping or section) with amylase agent;
The 3rd step: alternating temperature is processed:
After described material stirring is even, between normal temperature (if 10 degree Celsius are to 15 degree Celsius) and subzero 15 degree Celsius, carry out alternating temperature processing;
The 4th step: conventional machining:
After the complete blackening of described material color and luster, enter conventional machining process procedures such as frustrating mill, extraction, concentrated, desanding, refining, dehydration, dry, finished product packing.
Described second step: adding enzyme preparation, is to take the amylase agent that the weight proportion of described material and described amylase agent is 10000:0.1, sprays described material.
Described the 3rd step: alternating temperature is processed, be between normal temperature (if 10 degree Celsius are to 15 degree Celsius) and subzero 15 degree Celsius, carry out twice alternating temperature processing, be about to described material and be down to subzero 15 degree Celsius by 10 degree Celsius, by subzero 15 degree Celsius, thawed to 10 degree Celsius again, with this, repeat once; Or described material is down to subzero 15 degree Celsius by 15 degree Celsius, then thawed to 15 degree Celsius by subzero 15 degree Celsius, with this, repeat once.During cooling, want lucifuge, while thawing, will be aided with solar light irradiation and ventilate (wind speed is 4m/s); While thawing, also can be aided with illumination the ventilation (wind speed is 4m/s) of 100LUX illumination, 4000K colour temperature.
