Abstract

Provided is a processing method for flavored dried red dates. The method includes the following steps that 1, fresh mature red dates are collected and washed clean, pits of the red dates are removed, the red dates are sliced, fresh red date slices are collected and conveyed into a dryer to be dried at the drying temperature controlled within 55 DEG C-60 DEG C till the water content reaches 15%-25%, and then dried red date slices are obtained; 2, the dried red date slices are conveyed into freezing equipment under the sealing condition to be frozen for 12 h at the temperature of -20 DEG C, and then frozen and dried red date slices are obtained; 3, the frozen and dried red date slices are taken out and conveyed into a steamer, a layer of padding is laid on the steamer, then the frozen and dried red date slices are placed on the padding, and the frozen and dried red date slices are steamed for 1 h-2 h through steam to be ripened and flavored; 4, the steamed red date slices are cooled to the normal temperature and then conveyed into the drying equipment to be dried till the water content ranges from 10% to 20%, and the dried red date slices are naturally cooled at the normal temperature and then packaged, wherein the temperature of the drying equipment is controlled in a three-temperature-zone mode, and the red date slices can be eaten once a packaging bag is opened.

Description

The processing method that a kind of local flavor red date is dry
Technical field
The present invention relates to food processing technology field, be specifically related to the processing method that a kind of local flavor red date is dry.
Background technology
Red date is one of distinctive fruit of China, and the large I of fruit is divided into date and little jujube, has again long jujube, circle jujube not according to fruit shape.Modern medicine study shows, red date has following effect: 1. obvious antitumaous effect: the division growth of the adjustable cell of the CAMP in red date, is conducive to tumour cell and transforms to normal cell direction, therefore have antitumaous effect; Its crataegolic acid contained is strong cancer-resisting substance in addition; Abundant antioxidant vitamins C contained by it is also its anticancer major reason.2. expansible blood vessel, improves myocardial nutrition situation, strengthens myocardial contractive power.3. there is anti-allergic effects.4. have and alleviate the effect of poisonous substance to liver damage.5. the flavone compound in red date has calmness, hypnosis and hypotensive effect.6. the jamaicin contained by red date can suppress various bacteria.7. are a kind of natural cosmetology tonics.8. anti-ageing: red date, containing abundant antioxidant vitamins, to the invasion and attack of Green Tea Extract, therefore can have the effect delayed senility, as proverb said " within 1st, eat three jujubes, bear one's age well all the life ".9. antifatigue effect: containing Dammar saponin in red date, the endurance of people can be increased.From the above-mentioned effect of red date, we can take a hint: tonic is not more expensive better, and red date is inexpensive, instant, is the good thing in seasonal tonic.Although red date effect is distinguished, be also nine beneficial frauds, allly have that phlegm is wet, stagnant, tooth disease, worm patient, all should not eat more; Jujube is warm in nature, therefore the hot person of trouble phlegm also should not eat.On ordinary days eat jujube, also unsuitable many, appropriateness.The sugared content of jujube is high, therefore diabetic's inedibility.In addition, red date is perishable, containing harmful substances such as acid of filling the stomach, methyl alcohol, formaldehyde, formic acid in rotten jujube, easily causes poisoning.Chinese date various in style, among the people except the new fresh date that market is sold, also has dry product red date.
Therefore red date can be described as natural vitamin ball, and most particularly to contain cycli phosphate gland sweet for red date, can coronary artery dilator, strengthen myocardial contractive power, and the traditional Chinese medical science claims it to have help effect to be consistent.Nervous, in the heart confusing, sleep disorder or general Climacteric time, the prescription Chang Peijia red date of the traditional Chinese medical science, mainly red date has sedation, if therefore usually live nervous person, might as well add some red dates with food in entree soup.In red date composition, Vitamin C content is very high, and containing compositions such as the sweet and crataegolic acids of cycli phosphate gland, confirms through research, and above three is all containing the effect suppressing cancer, and that is red date has well pre-anti-cancer effect, the healthy food of applicable modern environment.But the red jujube taste of existing market is single, mostly still keep original taste.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of method, the processing method that delicious local flavor red date is dry.
Technical problem to be solved by this invention realizes by the following technical solutions:
The processing method that local flavor red date is dry, comprises following methods step,
1) collect ripe new fresh date, clean up, cut into slices by extracting red date stone, collect fresh of red date, dried in fresh feeding dryer by red date, bake out temperature controls at 55-60 DEG C, to moisture at 15-20%, obtains red date dry plate;
2) red date dry plate is sent in freezing equipment under air-proof condition, under the temperature conditions of subzero 20 DEG C freezing 12 hours, obtain red date freeze-drying sheet;
3) red date freeze-drying sheet is taken out, send into food steamer, first on food steamer, lay one deck bedding and padding, then red date freeze-drying sheet is placed on bedding and padding, utilizes steamed 1-2 hour, play slaking, seasoning effect;
Wherein bedding and padding are made up of the component of following parts by weight: 10 parts, rice-pudding leaf, apple 10 parts, 10 parts, sophora flower, green tea 10 parts, moyashi 15 parts, the bletilla striata 10 parts, kaempferia galamga 15 parts, gingili leaf 20 parts, 5 parts, brown sugar, lychee exocarp 10 parts, Chinese sorghum 10 parts, Chinese Toon Leaves 5 parts, camellia 5 parts, Folium Pterocaryae 15 parts, bitter-buckwheat embryo 5 parts, banana skin 5 parts, pomegranate seed 5 parts, sweet potato leaves 10 parts, 5 parts, the fruit of Chinese magnoliavine, akebi 5 parts, 5 parts, water caltrop leaf, lemon-grass 5 parts, 5 parts, Radix Glycyrrhizae, Buddha's hand 5 parts, dried peppermint leaf 5 parts, purslane 5 parts, pumpkin seeds 5 parts, lily 5 parts, hawthorn 5 parts, 5 parts, pine nut, fumigated by the bedding and padding of formulated, improve and increase fragrance and the health-care efficacy of red date,
4) steamed red date slices is cooled to normal temperature, send into drying plant, dry to moisture between 10-20%, the temperature of drying plant adopts the temperature control method of 3 sections of warm areas to carry out, the temperature of the first humidity province is incremented to 80 DEG C gradually from 70 DEG C, and time controling is at 10-30 minute; The temperature of the second humidity province is decremented to 70 DEG C gradually from 80 DEG C, and time controling is at 40-50 minute; The temperature of the 3rd humidity province is incremented to 76 DEG C gradually from 70 DEG C, and time controling is at 20-50 minute;
