Description

The preparation method of blueberry flowers and fruits leaf tea

Technical field

The invention belongs to agriculture field, relate to blueberry, especially a kind of preparation method of blueberry flowers and fruits leaf tea.

Background technology

Now, people have been familiar with the really abundant nutritive value of blueberry gradually, but blueberry flower and leaf contain the multiple composition splendid to human body equally, and human body is had very high health-care effect.Scientific research confirms, contains vegetables and the fruit of the content of abundant nourishing healthy composition, especially anthocyanidin far above other in the blueberry fruit.Often edible blueberry fruit product can strengthen eyesight significantly, anti-eye strain, and skin nutrition delays the cranial nerve aging; The disease of capillaries that is caused by diabetes there is therapeutic action, and can strengthens cardiac function, the prevention senile dementia.

Find by analysis of components the blueberry leaf, contain a large amount of compositions in the blueberry leaf equally to the human body beneficial, especially in the blueberry production process, after the fruit harvest, reasons such as some fruit is relatively poor owing to maturity, particle is little, mouthfeel difference can't listing become commodity, have influenced operator's economic benefit.Nutritious by developing to the processing of the remaining fruit of blueberry, blueberry leaf and blueberry flower, clearly good to eat, have and increase the product of building beneficial body.

Though American-European in recent years scientific research personnel has carried out extensive studies to the function of blueberry fruit, many blueberry fruit food, health products and medicine have been developed.But, up to now, also seldom see research and development to the blueberry leaf.

Summary of the invention

The object of the present invention is to provide a kind of preparation method of blueberry flowers and fruits leaf tea, be intended to the processing of the remaining fruit of blueberry, blueberry leaf and blueberry flower can develop nutritious, clearly good to eat, have and increase the product of building beneficial body.

The object of the present invention is achieved like this:

A kind of preparation method of blueberry flowers and fruits leaf tea, step is:

(1) preparation of blueberry leaf:

The blueberry leaf of plucking after the blueberry fruit harvest, blade carries out before reddening, clean after the harvesting, carry out 15-20 hour air dry then, with the dried blade cloth bag of packing into, crumple and be placed on after 10-20 minute in the drying box and under 90-110 ℃ of temperature, dry 50-70 minute, be ground into blueberry leaf powder;

(2) preparation of the remaining fruit of blueberry:

After fruit little particle, that colour-difference can not be gone on the market is picked out, remove foreign material, the refrigerator-freezer pre-freezes of cleaning, drain, pack into such as branches and leaves, the pre-freeze temperature is-30 ℃; Then precooling is transferred to-35 ℃, open dry door, pack into the blueberry fruit of deep colling, shut door, start the vacuum unit and find time, when vacuum reaches 60Pa, begin heating, need to guarantee stable working vacuum degree in the heating process, and guarantee that the article maximum temperature is no more than 50 ℃, reaches 80-85% until average dehydration;

(3) selection and the preparation of blueberry flower:

The blueberry flower is chosen in to be selected the overstocked flower of flowering shrubs florescence or is about to withered petal to pluck, and the petal after the harvesting is through cleaning, air dry or preserve stand-by after utilizing the drying machine drying;

(4) preparation of blueberry flowers and fruits leaf tea:

In per 100 weight parts waters, add 0.65 part-1 part in blueberry leaf powder, add 0.2 part-0.33 part of blueberry fruit; Dry petal one to two lobe promptly gets blueberry flowers and fruits leaf tea finished product.

Advantage of the present invention and good effect are:

1, the sample that makes of the present invention is bright and lustrous, is aubergine, and the salubrious sense of the dense sweet sense of blueberry tartaric acid, blueberry leaf and the delicate fragrance of blueberry flower are arranged, and it is sour-sweet suitable enter the mouth, and it is natural to health drink to meet the modern, safety, health, the requirement of delicious food.

2, technology of the present invention is simple, and economic environmental protection to the potential health care and the medical value of further excavation blueberry, improves the per unit area yield benefit of blueberry, and the income that increases the blueberry operator is significant.

The specific embodiment

Be described in detail embodiments of the invention below; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.

A kind of preparation method of blueberry flowers and fruits leaf tea, step is:

(1) preparation of blueberry leaf:

After the blueberry fruit harvest, the leaf on the limb of predetermined beta pruning to be plucked, and will before blade reddens, be carried out, the organic acid content because blade reddens in the rear blade can reduce rapidly; Clean after the harvesting, carry out 15-20 hour air dry then,, crumpled 15 minutes, be placed on then in the drying box under 100 ℃ of temperature, got final product in dry one hour the dried blade cloth bag of packing into.

(2) preparation of the remaining fruit of blueberry:

Adopt vacuum-freezing process to carry out to the processing of the remaining fruit of blueberry, specific procedure is as follows: after fruit little particle, that colour-difference can not be gone on the market is picked out, remove foreign material, cleaning, drench such as the branches and leaves refrigerator-freezer pre-freeze of doing, pack into, the pre-freeze temperature is-30 ℃.Dry: as at first cold-trap to be chilled in advance-35 ℃, open dry door, pack into the blueberry fruit of deep colling, shut door, start the vacuum unit and find time, when vacuum reaches 60Pa, begin heating, need to guarantee stable working vacuum degree in the heating process, and guarantee that the article maximum temperature is no more than 50 ℃.Average dehydration reaches 82.6%.The freeze-drying blueberry has really kept original color, have strong fresh blueberry fruit aromatic odor, and rehydration is very fast, and aromatic odor is more strong after the rehydration, and the freeze-drying blueberry fruit after the rehydration is near the local flavor of fresh blueberry fruit.
