Abstract
The invention discloses a method for preparing quick-frozen litchi pulp in small packages and belongs to the field of food processing. The method is characterized by comprising the following steps: selecting raw materials, cleaning, removing peels and kernels, soaking, blanching, cooling, quick-freezing, weighing and packaging, and refrigerating, thereby obtaining the finished product. The method has the beneficial effects that the semi-transparent quick-frozen litchi pulp is fresh and cool in taste, and has peculiar fragrance and sweetness of fresh litchis after being naturally unfrozen. The quick-frozen litchi pulp contributes to enhancing immunity of a human body and improving disease resistance, can obviously alleviate the symptoms such as insomnia, amnesia and mental fatigue and is convenient to eat and easy to cook.
Description
Technical field
The present invention relates to a kind of processing method of food, especially relate to a kind of preparation method of inner wrapping quick-frozen lychee pulp.
Background technology
Lichee, is together known as " the large fruit in the southern part of the country four " with banana, pineapple, longan, originate in SOUTHERN CHINA, is subtropical fruit tree, aiphyllium, the most fish-scale shape of pericarp projection, cerise; Spending manyly, be rich in nectary, is important nectariferous plant; The translucent congealed fat shape of pulp, taste is fragrant beautiful, but storage endurance not.
The effect of lichee: 1, the contained abundant sugar of lichee has makeup energy, the effect having additional nutrients, also has to cerebral tissue the effect of taking a tonic or nourishing food to build up one's health, and can obviously improve insomnia, forgetful, refreshing tired symptom; 2, lichee, containing abundant vitamin C and protein, contributes to enhanced machine body immunity function, improves resistance against diseases; 3, in lichee, contain a kind of material that has hypoglycemic activity, very suitable to diabetic; 4, lichee has abundant vitamin, can promote the blood circulation of fine vascular, prevents the generation of freckle, makes skin Paint Gloss.
Lichee chance high temperature is perishable, and storage tolerance, can not realize the comprehensive utilization to lichee for being processed into quick-frozen lychee pulp, is convenient to store, and improves its economic worth and nutritive value.
Summary of the invention
The object of the invention is to solve the problem that lichee is difficult for storage, a kind of preparation method of inner wrapping quick-frozen lychee pulp is provided.
The present invention solves the technical scheme that its technical problem takes:
A preparation method for inner wrapping quick-frozen lychee pulp, is characterized in that: adopt that raw material is selected, cleaned, the processing process of peeling and core, immersion, blanching, cooling, quick-frozen, weighing and bagging, refrigeration, finished product, concrete operation step is:
A, raw material are selected: the lichee picking is removed to branches and leaves, select size evenly, without the fruit of disease and pest, be raw material;
B, cleaning: select litchi fruits is rinsed well with clear water, removed foreign material;
C, peeling: adopt the method for manual peeling, first with pocket knife, from the handle of litchi fruits, scratch downwards, with hand, peel off skin, firmly core is extruded, litchi pulp is dropped in soak immediately;
D, immersion: the soak of preparation 1% calcium chloride and 0.8% citric acid, soak litchi pulp 30 minutes, play the effect that prevents the soft rotten generation brown stain of pulp;
E, blanching: the object of blanching is mainly further to carry out sterilization treatment, prevents the generation of enzymatic river bank phenomenon; Litchi pulp in soak is pulled out, dropped in the blanching solution that contains 0.5% calcium chloride and 0.5% citric acid, temperature is 100 ℃, blanching 2-3 minute;
F, cooling: the litchi pulp after blanching is pulled out rapidly, puts into clear water rinsing and is cooled to 6-8 ℃;
G, quick-frozen: cooled litchi pulp is drained to moisture, scatter and be spread out on conveyer belt, send into rapidly in the refrigerating chamber of-25 ℃ freezing 40 minutes;
H, weighing and bagging: frozen litchi pulp to be rejected to color, the not good part of form, after accurately weighing, pack in plastic packaging bag, its weighing error must not be greater than ± and 2%;
I, refrigeration: packaged litchi fruits is packed in the cardboard box of insulation, waterproof, upper and lower seam glues with adhesive tape, is placed under-15 ℃ of conditions and refrigerates, and treats that labeling dispatches from the factory.
Beneficial effect: the product of the present invention shape that is translucent, clean taste, after naturally thawing, its pulp has the distinctive perfume (or spice) of fresh lichee, sweet flavour.This product contributes to enhanced machine body immunity function, improves resistance against diseases, can also obviously improve insomnia, forgetful, refreshing tired symptom, and instant is simple to operate.
