Abstract
The invention provides a preparation method of asparagus tea. The preparation method comprises the following steps: performing vacuum glassy drying on cut circular asparagus flakes, wherein the temperature of the cut circular asparagus flakes is required to be rapidly reduced to minus 24 to minus 28 DEG C during the glassy drying within 30-35min, the vacuum degree is 40-50Pa, the heating temperature is 40-55 DEG C, and the drying lasts for 22-26h; and sublimating to obtain the asparagus tea, wherein the dissolving-out quantity of potassium ions of the asparagus tea is more than 70.26mg/L when the asparagus tea is soaked for more than 5min at more than 25 DEG C. no additives are added during drying in the method, the sensory quality such as color, luster, shape, scent and good taste and the nutritional ingredients of the fresh asparagus are kept to the maximum extent, the dissolving-out quantity of the nutritional ingredients in the asparagus tea can be increased, and high market development value is achieved.
Description
Technical field
The present invention relates to a kind of preparation method and application thereof of drink, especially a kind of preparation method of asparagus tea and application thereof.
Background technology
Asparagus is a kind of excellent famous and precious vegetables of holding concurrently of sampling, and formal name used at school asparagus, is Liliaceae Asparagus perennial root herbaceous plant, originates in Mediterranean, and there is establishing in large scale in China now.In asparagus, contain abundant potassium ion, cancer and cardiopathic control are played an important role.In addition, asparagus is rich in dietary fiber, contain the indispensable amino acid of human body, mineral matter and other various nutrient elements, and contain the multiple bioactive ingredients such as Chinese honey locust glucoside, flavonoids, there is the anti-ageing various biological function of waiting for a long time, be listed in world's " one of ten large famous dishes " and " the first anticancer fruit and vegetable ".
At present, the asparagus of China be mainly eat raw, quick-frozen or dry after be processed into instant powder.And in asparagus, containing a large amount of thermal sensitivity compositions, traditional diamond-making technique easily loses.
Vitrescence dry technology full name is the biological reversible dry technology of vitrescence, is based on cell biology and biochemical theory, modern biology investigative technique is injected into a kind of new high-preserved dry technology developing in traditional food production process.
The dried fruit-vegetable food of vitrescence, maximum feature is the nutritional labeling that can farthest keep the sensory quality of foods such as the original form of fresh fruit of vegetables, color and luster, smell, good taste and ecosystem fruits and vegetables, high, lightweight, the easy storage and transport of product quality, also being referred to as space food, is natural, green, safe now instant natrient food.
But, different fruit-vegetable foods, in vitrescence dry run, treatment conditions difference, has great impact to the quality of product, explores for asparagus the process conditions that it is optimized the most, is present stage technical problem urgently to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method of asparagus tea.
Technical problem to be solved by this invention is to provide the application of above-mentioned preparation method's gained asparagus tea.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A preparation method for asparagus tea, concrete steps are:
(1) select asparagus as raw material, through sorting, cleaning, draining, segment, section;
(2) the asparagus disk of cutting being placed in to vacuum vitrescence drying machine is dried, wherein, in vitrescence dry run, cooling requires product temperature to be reduced to rapidly-24～-28 DEG C, time is 30～35min, vacuum 40～50Pa, heating-up temperature is 40～55 DEG C, be 22～26h drying time, distillation obtains asparagus tea, gained asparagus tea in temperature more than 25 DEG C, water soaking 5min when above the stripping quantity of potassium ion be greater than 70.26 in mg/L.
Preferably, the preparation method of above-mentioned asparagus tea, in described step (1), asparagus is fresh organic asparagus.
Preferably, the preparation method of above-mentioned asparagus tea, in described step (2), product temperature is reduced to-25～-26 DEG C rapidly, and the time is 32～34min, vacuum 40～45Pa, heating-up temperature is 57～52 DEG C, be 23～25h drying time.
The application of above-mentioned preparation method's gained asparagus tea, 40～60 DEG C of water soakings were directly drunk after 15～30 minutes, effectively promoted potassium ion stripping.
Preferably, the application of described preparation method's gained asparagus tea aspect the health products of preparation control cardiovascular and cerebrovascular disease.
The invention has the beneficial effects as follows:
The preparation method of above-mentioned asparagus tea, taking asparagus as raw material, direct vitrescence is dried to asparagus tea and drinks, in dry run without any interpolation, greatly sensory quality of food and the nutritional labeling such as the original color and luster of the new fresh asparagus of the reservation of degree, form, smell, good taste, and can improve the stripping of nutritional labeling in asparagus tea, the corresponding asparagus tea that wherein dissolution rate of potassium ion is prepared higher than other method.Long-term drinking, contributes to supplement potassium element, is to provide the good merchantable brand of nutrition and health care, has opened up new approach for the processing of asparagus, has expanded the market of asparagus, has the larger market development to be worth.
