Description

A kind of processing technology of nutrient sugar asparagus lettuce

Technical field

The present invention relates to a kind of processing method of food, especially relate to a kind of processing technology of nutrient sugar asparagus lettuce.

Background technology

Asparagus lettuce, the aerial stem of plant can be edible, and stem skin is green in vain, and stem meat is tender and crisp, and young tender stem is emerald green, changes white green after ripe.Also known as lettuce, one to biennial vegetable, the rhizome of main edible meat.Tender leaf is also edible.Containing asparagus lettuce element in stem, leaf, bitter, has analgesic act on, the strong adaptability of asparagus lettuce, can spring and autumn or overwintering cultivation, based on spring cultivation, summer results.

The effect of asparagus lettuce: 1, open dredge profit, disappear long-pending lower gas: the pure and fresh and slightly bitter taste of asparagus lettuce taste, can be stimulated digestion enzyme secretion, improve a poor appetite, its milk-like slurry, the secretion of gastric juice, glandula digestive and bile can be strengthened, thus promote each Alimentary function, digestive function weakens, in alimentary canal acid reduce and the patient of constipation especially favourable; 2, strong body, cancer-resisting: asparagus lettuce contains multivitamin and mineral matter, has the effect regulating nervous function, is rich in the absorbable ferro element of human body in organic substances contained by it, very favourable to there being hypoferric anemia patient.The hot water extract of asparagus lettuce has very high inhibiting rate to some cancer cell, therefore can be used to cancer-resisting again; 3, the logical breast of diuresis: asparagus lettuce potassium content is much higher than sodium content, is conducive to the water-electrolyte balance in body, promotes to urinate and galactopoiesis, has certain dietary function to hypertension, oedema, heart patient.

The growth cycle of asparagus lettuce is short, and not storage endurance, for being processed into the comprehensive utilization that nutrient sugar asparagus lettuce can realize asparagus lettuce raw material, being convenient to store, improving its economic worth and nutritive value.

Summary of the invention

The object of the invention is the problem solving asparagus lettuce not storage endurance, a kind of processing technology of nutrient sugar asparagus lettuce is provided.

The present invention solves the technical scheme that its technical problem takes:

A processing technology for nutrient sugar asparagus lettuce, is characterized in that: the processing process adopting pretreatment of raw material → sclerosis → blanching → sugaring → candy → upper sugar-coat, and concrete operation step is:

(1) pretreatment of raw material: the asparagus lettuce selecting fresh mature, removes bamboo shoot leaf and crust, be cut into long 7cm, wide 2.5cm rectangular;

(2) harden: asparagus lettuce bar is put into concentration be 2% limewash soak 5-7 hour, then with clear water rinsed clean repeatedly, remove unnecessary limewash;

(3) blanching: the asparagus lettuce bar hardened is put into boiling water pot, pulled out after blanching 23-25 minute, dropped in cold water and cooled;

(4) sugaring: cold asparagus lettuce bar is put into pot, adds the maltose of total reducing sugar amount 3 ∕ 4, heating and cooking, boils after 40-45 minute off the pot, pours sugaring 5-6 days in cylinder into;

(5) candy: asparagus lettuce bar, liquid glucose are poured in pot again, add remaining maltose, first change slow fire boiling 3-5 hour again with very hot oven, wait to boil the wire drawing of liquid glucose energy;

(6) upper sugar-coat: pull asparagus lettuce bar out, drain liquid glucose, put into water caltrop Icing Sugar and stir, then sieve removes unnecessary Icing Sugar, packs, be finished product with food plastic bag, with food with getting.

Beneficial effect: product even thickness of the present invention, tissue are fine and smooth, soft, nutritious, have the local flavor of asparagus lettuce delicate fragrance sweetness, fresh and sweet tender and crisp; This product is rich in the multiple nutrients such as vitamin and mineral matter material, easily be absorbed by the body, contribute to the immunologic function strengthening body, can improve a poor appetite, promote digestion, there is Appetizing spleen-tonifying, open and dredge sharp, to disappear long-pending lower gas and cancer-resisting effect, the health preserving health-care food of a kind of low sugar, low fat, instant, all-ages.
