Abstract
The invention discloses a dried selenium-enriched purple sweet potato processing technology. The dried selenium-enriched purple sweet potato processing technology comprises the following steps of cleaning up, draining, cutting, drying purple sweet potato slices in the sun until semi-dried purple sweet potato slices having moisture content of 45 to 60% are obtained, drying by an air dryer, carrying out sterilization by an air dryer drying-sterilization combined technology, and carrying out vacuum packaging. Through the combination of air-drying and air-dryer drying, the dried selenium-enriched purple sweet potato processing technology does not destroy nutritional values of purple sweet potatoes and retains an original taste of purple sweet potatoes. Dried selenium-enriched purple sweet potato obtained by the dried selenium-enriched purple sweet potato processing technology has a beautiful color and a crispy taste and is rich in nutrients.
Description
Technical field
The present invention relates to the purple potato technique for processing dried of a kind of rich selenium method, belong to food processing field.
Background technology
Purple potato is black potato again, and potato meat is purple to darkviolet.It also is rich in selenium element and anthocyanidin except the nutritional labeling with common Ipomoea batatas.Purple potato is nutritious and have a special health care; Contain the protein about 20%; Comprise 18 seed amino acids, be prone to by human consumption and absorption, comprising 8 kinds of vitamins such as vitamin C, B, A and 10 several kinds of mineral elements such as phosphorus, iron; The anthocyanidin that is rich in it has significant anti-oxidation characteristics, and antidotal function is arranged; French scientist Maas chief reins in doctor and finds that anthocyanidin is natural strong effect free radical scavenger.Anthocyanidin has prevention and therapeutic action to more than 100 kinds of diseases, is described as the seventh-largest essential nutrients after water, protein, fat, carbohydrate, vitamin, mineral matter.Anthocyanidin is the disease preventing and treating found of present scientific circles, safeguard human health the most directly, the most effective, safest free radical scavenger, its ability of removing free radical is ascorbic 20 times, 50 times of vitamin E.Anthocyanidin has small molecule structure, is that unique ability sees through the material that blood-brain barrier is removed free radical protection brain cell, can reduce some harm that antibiotic is given human body simultaneously, and purplish red potato is one of primary raw material of anthocyanidin.
Purple potato content of cellulose is high, can increase faecal volume, promotes enterogastric peristalsis; The mucus, pneumatosis and the putrefaction that are detained in the cleaning enteric cavity, noxious material in the defecate and carcinogen keep stool unimpeded; Improve digestive tract environment, prevent the generation of enterogastric diseases.Purple potato also has pharmacological actions such as antioxidation, antimutagenic effect, hepatoprotective effect, minimizing cardiovascular disease.
Existing potato is done, the manufacturing approach of potato chips has weak point: the one, and quick-frozen makes potato chips include that sugar reduces and the distribution of sugar is uneven more, and made potato chips not only mouthfeel are not good enough, and lack nutritive value; The 2nd, this technology is frying technological process, is split by the world health group to be junk food; The content of starch height of purple potato, as adopting the microwave film-making, its starch not only can not produce crisp and fragrant and do under the effect of microwave, and can make the starch in the potato chips form a muscle, both has been unfavorable for eating, and is unfavorable for healthy yet; Because microwave leans on the molecular thermalmotion heating of food itself, the look that therefore can't form the baking potato chips is fragrant.
Summary of the invention
In order to overcome the deficiency of the manufacturing approach that has potato chips now, the invention discloses the purple potato technique for processing dried of a kind of rich selenium method, utilize processing method of the present invention can either keep purple potato original flavor, the purple potato that has the delicious and crisp mouthfeel is again done.
The purple potato technique for processing dried of a kind of rich selenium of the present invention method is characterized in that may further comprise the steps:
1. clean: the purple potato of rich selenium is cleaned, then draining;
2. section: purple potato is cut into slices with slicer;
3. airing: purple sweet potato chips is dried in the air to half-dried under the sun, dry in the air to the purple sweet potato chips moisture be 45～60%;
4. oven dry: dry with air-dry machine.
The purple potato technique for processing dried of a kind of rich selenium of the present invention method is characterized in that further comprising the steps of:
Sterilization: the air-dry machine oven dry combines the processing technology of sterilization simultaneously.
The purple potato technique for processing dried of a kind of rich selenium of the present invention method is characterized in that further comprising the steps of:
Vacuum-packed: adopt polybag vacuum inner wrapping, packaging process is implemented at dust proof workshop.
Technical characterictic of the present invention comprises the technology that adopts airing to combine the air-dry machine oven dry, and the purpose of doing like this is: neither destroy the nutritive value of purple potato, can keep purple potato original flavor, can make made purple sweet potato chips golden yellow color, mouthfeel delicious and crisp again.
The specific embodiment
Embodiment 1:
The purple potato technique for processing dried of a kind of rich selenium of the present invention method may further comprise the steps:
1. clean: the purple potato of rich selenium is cleaned, then draining;
2. section: purple potato is cut into slices with slicer;
3. airing: purple sweet potato chips is dried in the air to half-dried under the sun, dry in the air to the purple sweet potato chips moisture be 45～60%;
4. oven dry: dry with air-dry machine.
Embodiment 2:
The purple potato technique for processing dried of a kind of rich selenium of the present invention method may further comprise the steps:
1. clean: the purple potato of rich selenium is cleaned, then draining;
2. section: purple potato is cut into slices with slicer;
3. airing: purple sweet potato chips is dried in the air to half-dried under the sun, dry in the air to the purple sweet potato chips moisture be 45～60%;
4. oven dry: dry with air-dry machine;
5. the air-dry machine oven dry combines the processing technology of sterilization simultaneously.
Embodiment 3:
The purple potato technique for processing dried of a kind of rich selenium of the present invention method may further comprise the steps:
1. clean: the purple potato of rich selenium is cleaned, then draining;
2. section: purple potato is cut into slices with slicer;
3. airing: purple sweet potato chips is dried in the air to half-dried under the sun, dry in the air to the purple sweet potato chips moisture be 45～60%;
4. oven dry: dry with air-dry machine;
5. sterilization: the air-dry machine oven dry combines the processing technology of sterilization simultaneously;
6. vacuum-packed: inter-adhesive when packing greatly in order to prevent that the purple potato of rich selenium is dried, influence outward appearance and get the food convenience, polybag vacuum inner wrapping, packaging process is implemented at dust proof workshop.
The major defect of heated-air drying is to place drying under the higher temperature for a long time, thereby possibly cause severe impairment to local flavor, color, the nutriment of dried sweet potato.Technical characterictic of the present invention comprises the technology that adopts airing to combine the air-dry machine oven dry, and the purpose of doing like this is: neither destroy the nutritive value of purple potato, can keep purple potato original flavor, can make made golden yellow, the mouthfeel delicious and crisp in purple potato dry color pool again.
