Description

A kind of processing method of sweet and sour asparagus lettuce sheet

Technical field

The present invention relates to a kind of processing method of food, especially relate to a kind of processing method of sweet and sour asparagus lettuce sheet.

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.

Asparagus lettuce growth cycle is short, not storage endurance, and economic benefit is low, for being processed into the comprehensive utilization that sweet and sour asparagus lettuce sheet can realize asparagus lettuce raw material, instant, and being convenient to store, improving its economic worth.

Summary of the invention

The object of the invention is to solve asparagus lettuce growth cycle problem that is short, not storage endurance, a kind of processing method of sweet and sour asparagus lettuce sheet is provided.

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

A processing method for sweet and sour asparagus lettuce sheet, is characterized in that: the processing process adopting asparagus lettuce selection → section → sclerosis → sulphuring treatment → blanching → dipping → infusion → upper sugar-coat → packaging, and concrete operation step is:

(1) raw material is selected: select Fresh & Tender in Texture, without going rotten, the asparagus lettuce that has no mechanical damage is raw material;

(2) cut into slices: remove bamboo shoot leaf and crust, clean with flowing clear water, then be cut into the thin slice of 8mm;

(3) harden, sulphuring treatment: by the asparagus lettuce after cleaning, be placed in the aqueous solution containing 0.45% calcium chloride and 0.12% sodium pyrosulfite, soak 55min, carry out hardening and sulphuring treatment, then use clear water rinsing, eliminate raffinate, drain moisture;

(4) blanching: treated asparagus lettuce, in boiling water, blanching 5min, pulls out, rapidly with cold water cooling, drains away the water;

(5) flood: be mixed with sucrose, starch syrup and mature vinegar the sugar-vinegar liquid that concentration is 45%, pour into and fill in the cylinder of asparagus lettuce, dipping 18h, sugar-vinegar liquid should flood bamboo shoot sheet;

(6) infusion: the asparagus lettuce pulling dipping out, the clean sugar-vinegar liquid of drop; With sucrose and rice vinegar allotment impregnation concentration to 50%, boil in pot, add a little Radix Glycyrrhizae, brush-cherry seed, honeysuckle, pour asparagus lettuce into, after again boiling, use slow fire boiling instead, until sugar-vinegar liquid concentration reaches 58%, middle gradation adds honey and raspberry juice;

(7) toast: the asparagus lettuce pulling infusion out, the clean sugar-vinegar liquid of drop, is placed on drip pan, sends into drying room under 75 DEG C of conditions, baking 8h, and centre is stirred 3-4 time, until surface is tack-free;

(8) upper sugar-coat: the asparagus lettuce taking out baking, adds by the obtained Icing Sugar of pinenut, sesame, white sugar, constantly turns, and bamboo shoot sheet is evenly adhered Icing Sugar, and then sieve goes unnecessary Icing Sugar namely to make;

(9) pack: by finished product quantitative separating in sealed polyethylene plastic bag, pack.

Beneficial effect: product surface of the present invention is sparkling and crystal-clear full, and smooth mouth feel is clear and melodious, sour and sweet palatability, with the delicate fragrance of asparagus lettuce; 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.
