Abstract
The invention relates to a processing method of instant washing-free red dates. The processing method comprises the steps of picking fresh red dates and cleaning, drying the red dates by using hot air until the water content is 45-50 percent after sterilizing by using high-temperature superheated steam; then performing vacuum drying until the water content is reduced to 30-35 percent, denucleating; finally, softening the red dates by using high-temperature steam. According to the processing method, the red dates are made into semi-dry dates by adopting a twice-drying method, thus excessive water can be rapidly evaporated, thermosensitive components and easily-oxidizing components in the red dates are effectively prevented from being damaged and decomposed, and original nutritional ingredients are maximally kept; by adopting a softening process, the red dates which are hardened are softened, thus the mouth feel and the flavor of the red dates are greatly improved, and the red dates are strong and chewable, and meet double demands of nutrients and mouth feel of a consumer. The instant washing-free red dates are long in guarantee period, are ready to eat after bags are opened, and are very convenient.
Description
Technical field
The invention belongs to food production field, be specifically related to a kind of processing method of instant wash-free red dates.
Background technology
Red date, has another name called date, originates in China ，Shi China tradition fruit, and oneself reaches more than 3000 year cultivation history, has very high economic worth.Red date is a kind of nutrient excellent product, is described as " kings of all kinds of fruits ".Red date contains necessary multivitamin and 18 seed amino acids and the mineral matters of human body such as abundant vitamin A, B, C, wherein ascorbic content is unexpectedly up to grape, apple 70～80 times, the content of rutin (citrin) is also very high, and these two kinds of vitamins have certain effect to anti-cancer and preventing hypertension, high fat of blood.Red date, as integration of drinking and medicinal herbs fruit, is always regarded as nourishing top grade.Red date has the invigorating the spleen of nourishing blood, tonifying five zang organs, controls the effects such as deficient, and the various diseases such as hypertension, cirrhosis are had to good curative effect.Red date is with local flavor and itself all next high nutrition and the high medical value of its naturally scarlet color and luster, sour and sweet palatability, all very popular from ancient times to the present.
Water content and the sugar content of new fresh date are all very high, and respiratory intensity is large, very easily rotten under normal temperature, not storage tolerance.While especially gathering in the crops, run into overcast and rainyly, the easy to crack and fungal infection of jujube fruit, causes a large amount of losses.Therefore red date pluck after except eating raw on a small quantity, most must through drying could long-term storage and deep processing.
The red date of selling on the market is now common dry jujube mostly, shrivelled hard, needs after rehydration just ediblely, can not meet consumer's demand easily and efficiently.Some instant red date products exist the holding time short, easily addle rottenly, the problems such as directly eating mouth feel is bad, can not meet the demand of consumer to nutrition, mouthfeel.
Summary of the invention
The invention provides a kind of processing method of wash-free red dates, for consumer provides, a kind of mouthfeel is good, the processing method of the instant wash-free red dates of nutrition health.
technical scheme of the present invention:
A processing method for instant wash-free red dates, it comprises the following steps:
Select without going mouldy, without the new fresh date of moth, carry out flowing water cleaning, then with hyperthermia and superheating steam, carry out sterilization, then by red date with hot-air seasoning to moisture content to 45%-50%;
Red date is carried out to vacuum drying, be down to 30%-35% to moisture content; Red date is carried out to stoning processing; Described vacuum drying vacuum is 0.03-0.06Mpa;
Finally with high-temperature steam, red date is softened to processing, treatment temperature is that 90-100 ℃, steam relative humidity are that 60-80%, vapor (steam) velocity are that 20-30m/s, processing time are 3-5min.
During described sterilization, the temperature of hyperthermia and superheating steam is 150-200 ℃, and vapor (steam) velocity is 5-10m/s, and sterilizing time is 40-60s.
The baking temperature of described hot-air seasoning is 55-60 ℃, and dry wind speed is 15-25m/s.
positive beneficial effect of the present invention:
The present invention is dried red date red date is made to half-dried jujube at twice, first carries out hot-air seasoning to certain moisture content; Carry out again vacuum drying, not only effectively evaporate unnecessary moisture, can effectively avoid the destruction of heat-sensitive ingredients in red date and oxidizable composition to decompose, kept to greatest extent original nutritional labeling.
The present invention adopts softening processing, by selecting suitable softening treatment temperature, steam moisture and processing time, can not only make oneself through hardening red date, ease back, and mouthfeel and the local flavor of red date have been improved, make the red date Geng Jing road of tasting, nutty, nicier, meet the dual requirements of consumer to nutrition, mouthfeel.
Red date of the present invention is preserved at normal temperatures the shelf-life and can be reached 18 months, has effectively extended its holding time, and product not only can instant bagged, and nutrition is delicious, edible very convenient, is good for one's health.
