The processing method of a kind of mint teaTechnical field
The present invention relates to the processing method of a kind of mint tea.
Background technology
Peppermint is herbaceos perennial, Labiatae Mentha.Be often used as natural perfume material because being rich in the volatile ingredients such as menthol, its mint extract Peppermint essential oil is also widely used in food, cosmetics and medicine trade.Except containing volatile ingredients such as menthones, menthol, menthyl acetates in peppermint, also containing abundant carbohydrate, lipid, protein and trace element etc.The acidic polysaccharose class material wherein combined with protein containing a class, has hypoglycemic, hypotensive, enhancing immunity of organisms, anti-inflammatory, the multiple efficacies such as anticancer.So peppermint has the Development volue that well keeps healthy.
Mint tea processing method is a kind of system processing method of carrying out based on fresh leaf characteristic and prouctiveness, four processes such as mainly comprising spreading for cooling, complete, knead, be dry.The botanical characteristics of peppermint and tealeaves have a lot of similarity, easy dehydration, easily there is oxidation, knead can be shaped, dry can solid.Utilize Tea Processing principle to process dried peppermint leaf, make mint tea taste better, dry dark brown pool is emerald green, and commodity performance is better, saves production cost simultaneously.But about the technological parameter in mint tea process does not have report.
Summary of the invention
The object of the invention is the health-care efficacy making full use of peppermint, provides a kind of botanical characteristics processing method based on peppermint, provides the mint tea product being convenient to Instant Drinks, and the method simple and effective is suitable for producing.
The present invention is achieved by the following technical solutions, the present invention includes following steps:
(1) pluck fresh mint leaf the 1 to 3 blade (peppermint shoot apex counts from top to bottom), and choose foreign material;
(2) to pluck after dried peppermint leaf carry out Rapid Cleaning, eccysis dust and to cleaning after dried peppermint leaf dewater, process of dry, remove surface moisture;
(3) be transported in steam inactivation machine by dried peppermint leaf and complete, vapor (steam) temperature is 110-120 DEG C, and fixation time is 1-5min;
(4) knead the dried peppermint leaf after steam beating, the time of kneading is 20min, and pneumatics 5min, gently presses 15min, deblocks 1 time in centre;
(5) cylinder roasting machine is utilized to carry out rolling bar;
(6) in song milli roasting machine, moulding and drying are carried out to dried peppermint leaf, fry to water content about 5%;
(7) screening machine is utilized, by selected for the mint tea screening after drying.
Step (3) concrete steps are: be placed in steam inactivation machine by dried peppermint leaf after cleaning and kill, temperature is 110 DEG C, and fixation time is 2min, leaf color jade green after completing.
Step (4) concrete steps are: utilize 40 type tea twisting machines, 55-60r/min, kneads dried peppermint leaf, and pneumatics 5min, gently presses 15min, deblock 1 time in centre.
The present invention has the following advantages compared to existing technology: the present invention is the botanical characteristics processing method based on mint tea, adopts the method for steam beating, keeps the emerald green of peppermint, utilizes cylinder to fry moulding in conjunction with pot, finally forms graininess product.The present invention is that the production of mint tea provides scientific and efficient method, to produce mint tea be graininess, kidney ellipsoid, color and luster is emerald green, and fragrance is pure and fresh, and flavour is tasty and refreshing, and saves the nutritional labeling in peppermint to greatest extent, promotes the mouthfeel of mint tea.
Mint tea can calm intense strain, the Xie Yu that refreshes oneself, cough-relieving, alleviation cold headache, whet the appetite aid digestion, gaseous distention or indigestion can be eliminated to alleviate throat's discomfort, help appetizing, digestion, stomachache and headache can be relaxed, and enhance metabolism, eliminate halitosis, Dealcoholic sobering-up; Have and strengthen muscle power, sedation, help digest, be applicable to being blended in various Herb Tea.Can be anti-halitosis in advance.Stomach invigorating is aid digestion, and wind dispelling is evil, controls headache.Build up resistance, feel sick, have a headache.
Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
The present embodiment comprises the following steps:
(1) pluck fresh mint leaf the 1 to 3 blade (peppermint shoot apex counts from top to bottom), and choose foreign material;
(2) to pluck after dried peppermint leaf carry out Rapid Cleaning, eccysis dust and to cleaning after dried peppermint leaf dewater, process of dry, remove surface moisture;
(3) be transported in steam inactivation machine by dried peppermint leaf and complete, vapor (steam) temperature is 115 DEG C, and fixation time is 3min, and weight-loss ratio is about 12%-18%;
(4) knead the dried peppermint leaf after steam beating, the time of kneading is 20min, and pneumatics 5min, gently presses 15min, deblocks 1 time in centre;
(5) cylinder roasting machine is utilized to carry out rolling bar;
(6) in song milli roasting machine, moulding and drying are carried out to dried peppermint leaf, fry to water content about 5%;
(7) screening machine is utilized, by selected for the mint tea screening after drying.
Step (3) concrete steps are: be placed in steam inactivation machine by dried peppermint leaf after cleaning and kill, temperature is 110 DEG C, and fixation time is 2min, leaf color jade green after completing.
Step (4) concrete steps are: utilize 40 type tea twisting machines, 55-60r/min, kneads dried peppermint leaf, and pneumatics 5min, gently presses 15min, deblock 1 time in centre.
Brew up with peppermint, bubble method the same with ordinary tea leaves, the wind and heat dispersing effect of menthol in peppermint, menthones can be utilized, and brew up have refrigerant sense, be the good medicine of reducing fever and causing diuresis.
Fresh leaf is transported to processing factory and checks and accepts after classification, should by kind, weather leaf, morning and afternoon leaf, Slopes leaf, blue or green strong age to separate with aged leaf and store green grass or young crops, spread.
Should spread at soft plaque, winnow with a dustpan on basket or thin bamboo strip pad.Spread thickness to want suitably, spring temperature is low, can be suitable thicker.Fine day air humidity is low can suitable thick stand, to prevent fresh leaf dehydration too much, affects frying.Rainwater leaf should suitable thin stand, to distribute moisture better.
The process of spreading should open and close door and window according to weather condition.Overcast and rainy door and window should open wide, dry fine day, and door and window should be opened less, to keep the freshness of fresh leaf.The relative humidity spreading room air controls about 90%, room temperature about 15 DEG C, and leaf temperature control, absolutely not must more than 35 DEG C below 30 DEG C.Spread the time unsuitable long, accomplish fresh leaf on the same day, the same day, frying was complete.
Following table is the nutrient content of mint tea:
nutrient content (every 100 grams)

Table 1
Through subjective appreciation, the mint tea produced is graininess, kidney ellipsoid, and color and luster is emerald green, and fragrance is pure and fresh, and flavour is tasty and refreshing.Show that the botanical characteristics mint tea processing method that the present invention is based on peppermint is feasible.
But peppermint can reduce the milk amount of puerpera, has certain excitant, the women that should not give lactation, period of pregnancy, child use.
