Abstract
The invention discloses a processing method of red dates, which comprises the following steps: pre-soaking, that is, soaking red dates in warm water for half an hour; cleaning, removing date pits, soaking the red dates after date pit removal in water treated by high temperature sterilization for 24-48 hours till peels of the red dates expand, taking the red dates out; freezing, unfreezing, and peeling the red dates, preparing a thick sugar solution with a mass concentration of 70%; boiling the thick sugar solution, putting the red dates in the thick sugar solution, boiling for 20-40 min; cooling and soaking for 2 hours; taking the red date blanks out, baking in a baking room at a temperature of 60-70 DEG C to obtain a water content of 20-30%, and grading packaging. The red dates processed by the method is good in taste, free of peels, free of date pits, and convenient to eat, does not cause the phenomenon of dysphagia, is easy to store, and does not deteriorate when stored for two years; with the low temperature baking method, nutritional ingredients in red dates are less in loss, and the product is rich in nutrients, and has the functions of health care and physical health improvement.
Description
Technical field
The present invention relates to food-processing method technical field, particularly a kind of processing method of red date.
Background technology
Red date has another name called date, is the fruit of Rhamnaceae jujube jujube, is traditional fruit of China, nutritious, has very high economic worth.Red date contains the nutritional labelings such as protein, amino acid, mineral matter, cellulose, the effect such as have the tonifying Qi of nourishing blood, invigorating the spleen, tonifying five zang organs, delay senility.Red date, with the local flavor of its naturally scarlet color and luster, sweet and sour taste and high nutrition and the high medical value of itself, is subject to people's favor deeply.
New fresh date water content and sugar content are all very high, respiratory intensity greatly, very perishable, be unfavorable for storage.Therefore people are often processed into dry jujube red date, and dry jujube appearance is hard, need soaked rear ability edible, and mouthfeel are bad.Another kind method is the lower candied date of water content that red date is processed into, direct-edible, but while eating, its red date skin is difficult for chewing, easily cancer of the esophagus throat; And when red date has jujube core, particularly child to eat, jujube core easily blocks throat, has certain danger.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome, the red date of prior art processing is shrivelled, mouthfeel is bad, red date belt leather is edible inconvenient, and jujube core easily blocks the problems such as throat, and a kind of processing method of red date is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of processing method of red date, comprises following steps:
A, pre-soaking, put into warm water by red date and soak half an hour;
B, cleaning, pull red date out after immersion, water is rinsed well;
C, stoning, extracting red date stone after cleaning;
D, again the red date after stoning is put into high-temperature sterilization treated water and soak 24-48 hour, until the epidermis of red date expands, pull red date out;
E, freezing, puts into refrigerating chamber by the red date of expansion freezing, until red date fully charge, then take out red date;
F, thaw, it is that the warm water of 30-40 DEG C soaks that red date is put into temperature, until red date thaws;
G, peeling, put into skinning machine peeling 30-50 second by the red date after thawing, and trickle cleans the epidermis of red date simultaneously;
H, configure dense liquid glucose, the mass concentration of dense liquid glucose is 70%;
I, boil, red date is put into dense liquid glucose and boil 20-40min;
J, cooling immersion, then pour out cooling immersion 2 hours by the red date boiling and liquid glucose;
K, jujube base is pulled out and sent into drying room baking, temperature is between 60-70 DEG C, until water content is between 20%-30%;
L, point grade packaged.
In described steps d, water is through 100 DEG C of high-temperature sterilization processing.
In described step k, the time of baking is 10-12 hour.
The invention has the beneficial effects as follows: the red date mouthfeel that this method processes is good, not belt leather is seedless, and instant there will not be the phenomenon of cancer of the esophagus throat; Easily preserve, can preserve and never degenerate for 2 years; Take the method for low-temperature bake, the nutrient loss in red date is less, nutritious, has health care, constitutional function; After soaking, adopt skinning machine peeling, greatly improved production efficiency.
