Description

Purple potato food and preparation method thereof
Technical field
The present invention relates to a kind of purple potato food of novelty, the invention still further relates to the preparation method of this purple potato food (for example purple potato food of quick-frozen).Existing purple potato series products has tangible difference and characteristics on purple potato food of quick-frozen of the present invention and the market.
Background technology
The true name of purple potato mountain, river purple is introduced China by Japan, has special health care.In the anticancer vegetables that Japanese national vegetables DKFZ announces recently, rank first.Purple potato content of cellulose height, this class material 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.Measure according to Institute of Analysis of Southern Yangtze University of the Ministry of Education of the state, the constituent content of mountain, river purple (μ g/g) is: zinc 4.11, iron 8.49, copper 2.44, manganese 1.34, calcium 446, selenium 0.0054; China's potato peaceful purple No. 1 constituent content (μ g/g) of breeding thus is: zinc 2.49, iron 6.23, copper 2.58, manganese 1.63, calcium 320, selenium 0.0071.In the purple potato zinc, iron, copper, manganese, calcium, selenium be natural, and iron, calcium content extra-high-speed.And selenium and iron are human body antifatigue, anti-ageing, the essential elements of enriching blood, has the good health care function, easily be absorbed by the body, stay in the serum effectively, repair cardiac muscle, strengthen immunity of organisms, remove the free radical that produces cancer in the body, suppress the division and the growth of the synthetic and cancer cell of DNA in the cancer cell, the generation of diseases such as prevention cancer of the stomach, liver cancer.Therefore, purple potato has the good health care function, is the first-elected health food in current nuisanceless, green, the organic food.
Present purple potato series products domestic market is also rare.The purple potato food of this class for example after vacuum frying or dehydration, adheres to various flavorings, does not perhaps carry out seasoning and directly packs.The purple potato Egg Tarts released of McDonald and for example, these purple potato food are liked by consumers in general very owing to added the healthy element of purple potato once releasing.But these food are owing to the oil content height, and the shelf-life, short the grade also had certain limitation.
In order to develop new purple potato food, for example, Chinese patent application numbers 200510122472.5 has been announced a kind of production method of purple potato beam as novel snack.Its raw material comprises ultra-fine sea-tangle powder, purple potato, xylo-oligosaccharide, and its basic model shape is various difform sugared beans forms, and extended pattern is the jam of fluid pasty state.It is health food of primary raw material and preparation method thereof that Chinese patent application numbers 200910067577.3 discloses with purple potato and blueberry, with purple potato and blueberry is the health food of primary raw material, purple potato and 10-50 weight portion blueberry with the 10-50 weight portion are primary raw material, add purple potato leaf, purple potato stem, blueberry leaf, blueberry flower or black pearl tomato again, and the pure natural raw material cordyceps militaris fruit body that from motherland's medicine treasure-house, filters out etc., extracting methods such as employing microwave are made with extra care and are formed.Above-mentioned two kinds of methods demonstrate fully the variation of the purple potato product development of class, to satisfy people's difference hobby.Yet this area wishes that still new purple tuber crops food is arranged, and is not particularly mainly comprised the food of other raw-food material by purple potato preparation basically, and wishes that the new purple tuber crops food of this class has good mouthfeel.
