Summary of the invention

The object of the invention is the problem that solution tomato not easily preserves, a kind of preparation method of nutrition sweetened tomato pulp is provided.

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

A kind of preparation method of nutrition sweetened tomato pulp, it is characterized in that: adopt select materials → clean → blanching removes the peel → repairs the processing process of stripping and slicing → cure process → low sugar boiling → dipping → high candy system → dipping → oven dry → shaping → packaging, concrete operation step is:

(1) select materials: choose fresh look red, be not raw material by comparatively strong, that pulp is plump, juice the is few little tomato of the harm of sick worm, flesh firmness;

(2) clean: tomato is put into rinse bath, washes the impurity on most surface;

(3) blanching peeling: tomato is poured in the hot water of 100-102 DEG C, blanching 10-20s, scald and easily depart to epidermis, drag for immediately in cold water and tomato rubbing is removed the peel;

(4) base of a fruit handle, small holes caused by worms are dug up, then are cut in half from centre with pocket knife by shaping, stripping and slicing: after tomato peeling;

(5) cure process: pouring the tomato block cut into concentration is in the limewash of 2%-3%, soaks 6-7 hour, then carries out rinsing with clear water, until without lime taste;

(6) low sugar boiling and dipping: heat water to 85 DEG C, add sucrose, stir and make it dissolve, compound concentration is the liquid glucose of 40%-45%, is heated to boil; Poured into by tomato, boil 28-35 minute, adjustment sugar concentration, makes it remain on 35%-40%, pours in dip tank, soaks 42-46 hour;

(7) high candy system and dipping: be the liquid glucose of 65% with sucrose compound concentration, add the citric acid of 0.35%-0.45%, be heated to boil, again impregnated tomato is poured in pot and boil, boiling 45-50 minute, period added 1 sucrose every 10-15 minute, when making sugar concentration finally reach 75%-80%, stopped heating; Treat that liquid glucose temperature drops to 45-50 DEG C, add a small amount of honey and lemon extract, stir evenly, soak 26-28 hour;

(8) dry: tomato is pulled out, drains the liquid glucose of attachment, then it is placed on bamboo grid equably, dry under putting into 70-75 DEG C of drying room, smoke 5-7 hour, manually fall to coil up and down, continue to dry 8-10 hour, until touch unconsciously moist, flexible with hand, sweetened tomato pulp;

(9) pack: arranged by sweetened tomato pulp shaping, packaging is finished product.

Beneficial effect: product of the present invention is glittering and translucent, the continuous meat of matter is thick, has the distinctive sour-sweet local flavor of tomato, sweet and sour taste; This product is rich in the multiple nutrients such as vitamin and mineral matter material, easily be absorbed by the body, can promote the production of body fluid to quench thirst, stomach strengthening and digestion promoting, contribute to the immunologic function strengthening body, having effect of softening blood vessel, blood pressure lowering and heart protecting, beautifying face and moistering lotion and cancer-resisting, is a kind of pollution-free food of natural pure, nutrient health.
