Description

A kind of preparation method of guava preserved fruit

Technical field

The present invention relates to the preparation method of preserved fruit, especially relate to a kind of preparation method of guava preserved fruit.

Background technology

Guava, is commonly called as Ba Le or pulls out son.Taiwan fragrant plant is happy is Myrtaceae Psidium fruit tree, and meat is very soft, and gravy enriches, and have a sweet taste, almost without seed, local flavor is close between pears and Zizyphus mauritiana Lamk.Its fruit ellipse, color breast is blue or green to milky white, extremely beautiful, and containing a large amount of potassium, iron, carrotene etc., nutrition is extremely abundant.Fragrant plant pleasure is one of the autochthonal fruit in Taiwan, or the diet fruit of first-class.Guava has spherical, oval, oval and foreign pyriform, and pericarp is common is green, red, yellow, pulp adularescent, redness, yellow etc.Fine and tender taste, clear and melodious fragrant and sweet, tasty and refreshing comfortable, be not often fed up with eating, be the best fruit of skin maintenance.Guava is nutritious, can increase appetite, promotes upgrowth and development of children, containing protein, fat, carbohydrate, vitamin A, B family vitamin, Vc, and calcium, phosphorus, iron.Guava is of high nutritive value, and with vitamin C, all higher than citrus, banana, pawpaw, tomato, watermelon, pineapple, iron, calcium, phosphorus content also enrich, and in seed, the content of iron is more better than other fruit, so preferably can eat down together.Eat can anti-aging in advance more, gets rid of effect of vivotoxin.

Guava is seasonal fruit, and water content is high, not easily preserves, and has effect of relieving summer-heat; Guava is less through the product of deep processing, and utilize fresh guava to make guava preserved fruit, product is nutritious, eats, preserves conveniently, can increase its nutritive value and economic benefit.

Summary of the invention

The invention provides a kind of preparation method of guava preserved fruit of nutritious, instant, solve the problem that guava raw material is not easily preserved, deep processed product kind is less, improve added value of product.

The technical scheme that the present invention takes is:

A preparation method for guava preserved fruit, is characterized in that, mainly comprise select materials, pretreatment of raw material, stripping and slicing, sclerosis, rinsing, blanching, cooling, sugaring, candy, dry, packaging Main process steps:

A, to select materials: choose maturity and be suitable for, without insect pest, without rotten, fresh guava;

B, pretreatment of raw material: guava epidermis of shooting off, tail of decaptitating, cleans with clear water;

C, stripping and slicing: be cut into the fritter that 20 × 20mm is square;

D, sclerosis: the guava block cut is dropped in the salt of 4-5% and soak 40-50 minute, pull rear clear water out and rinse 4-5 time, the limewash supernatant then putting into 0.6% soaks 2-4 hour;

E, rinsing: the melon block clear water rinsed clean after sclerosis, to melon meat in neutral, pull drop out clean;

F, blanching: melon block is dropped into leaching in the hot water of 100 DEG C and scald 18-20 minute, add appropriate malic acid and citric acid;

G, cooling: the melon block after blanching should be cooled to normal temperature rapidly, in order to avoid affect product brittleness;

H, sugaring: carry out sugaring with maltose, consumption is 70% of melon block weight, successively divides three times and adds sugar: first time sugaring 45% also adds a small amount of cold boiling water, to promote dissolving and the infiltration of sugar, the sodium hydrogensulfite simultaneously also adding 0.05% carries out protecting look, anticorrosion, and the sugaring time is 20-22 hour; Second time adds the sugar of 18%, continues sugaring 18-20 hour; The sugar of remainder all adds by third time, and sugaring 48-50 hour, wants often to stir melon block up and down, make melon block absorb sugared part equably, become sparkling and crystal-clear bright in each sugaring process;

I, candy: melon block together to be poured into together with liquid glucose and thoroughly carries out boiling, until sugar concentration reaches 70% in steel jacketed pan;

J, packaging, finished product: the melon block after candy is pulled out, draining sugar liquid, carry out vacuum packaging with food-grade polyethylene packaging bag after cooling, be finished product.

Beneficial effect: manufacture craft of the present invention is simple, raw material and tooling cost lower, it is convenient to implement,

Product is nutritious, mouthfeel is sharp and clear, taste is fresh and sweet, outward appearance is sparkling and crystal-clear bright, and have the fragrant of guava, this product is delicious and nourishing not only, be conducive to improving human metabolism, be rich in multivitamin, to prevent and treat diabetes, reduce blood sugar have special curative effect, there is effect that is anti-ageing, detoxication and toxicant eliminating function, all-ages, easy and simple to handle.
