Description

Method for producing balsam pear tea

The present invention relates to a kind of method of making raw material production balsam pear tea up to now as the edible balsam pear of vegetables.

Momordica is named as Momoredica Charantia, and its original producton location is a Tropical Asia, in the Okinawa and the area, nine divisions of China in remote antiquity of Japan a lot of people's plantations is arranged.Balsam pear contains explains unclear bitter taste glucoside, alkaloid, adenine and citrulling with rare bitter taste, and these have been considered to digestive pharmaceutical and medicine as intestines problem.And a large amount of vitamin Cs is contained in the balsam pear, and its fruit is used as vegetables in the past during the broiling summer in order to prevent tired edible, digestive pharmaceutical and medicine in the Okinawa area as intestines problem.Recently, just in the rare longevity in Okinawa county, the causality between the cancer of the stomach incidence and the death rate reduce is studied.

As mentioned above, balsam pear is a kind of vegetables that contain many to the very useful composition of human body, and this vegetables are only gathered in summer.The fruit of balsam pear has such defective, and it is similar to pears, contains a large amount of moisture when fresh (be 94.5%), rots easily and can not preserve.So balsam pear is only handled by this way, promptly fruit is thinly sliced after harvesting at once, and fry or boil with other food is then perhaps smashed fresh fruit as fruit juice to pieces and eaten.Therefore, people do not know that balsam pear can be prepared into tea.

On the other hand, because balsam pear has a kind of rare bitter taste, be a kind of extremely strange taste, although it contains and many useful composition of human body also is not easy to be accepted by many people.

Because the pulp of balsam pear contains a lot of moisture content, it has rare bitter taste, and to be used for beverage be unfavorable so balsam pear is considered to be used as tea, and people never consider that always the processing balsam pear is a tea.Yet the present inventor has noticed a kind of idea, balsam pear can be processed as tea in research balsam pear process.As a kind of result of research repeatedly, the present inventor has obtained the present invention.

Therefore, the purpose of this invention is to provide a kind of in order to obtain balsam pear tea the method for production balsam pear tea, it can be used to process never utilize as the balsam pear of processed food does not damage its useful component, and can remove the distinctive bitter taste of balsam pear, so that anyone takes like a shot it.

According to the present invention, the step that the method for production balsam pear tea adopts a preliminary treatment balsam pear is to be cut into them 3 to 20 millimeters thin slice, dry then balsam pear thin slice is reduced to 10 to 5% of weight when just cutting until their weight, then toast dry thin slice down, just can reach aforesaid purpose at 60 to 150 ℃.

When balsam pear thin slice during greater than 20 millimeters, drying efficiency is not high, be dry equably they also be difficult, when section during less than 3 millimeters, balsam pear be organized in cutting the time will seriously break, this is worthless.Preferably they are cut into 3 to 20 millimeters scope, scope is 5 to 15 millimeters preferably, and the degree of drying of balsam pear thin slice is relevant with subsequent step, i.e. baking procedure, and relatively the time, it is preferred that baking back weight is reduced to about 10 to 5% with fresh balsam pear.When degree of drying was low, it was difficult then will obtaining delicious tea through baking, even prolong stoving time.When degree of drying is high, just needs to shorten stoving time, and when degree of drying is low, just need to prolong stoving time.Low and drying time then produces bitter taste also in short-term when degree of drying, and this is worthless.

Now embodiments of the invention are explained in detail.

As preliminary treatment, earlier the balsam pear of harvesting to be cleaned with foreign matter such as earth, agricultural chemicals and adhere to analog flush away on the fruit are vertically cut balsam pear, when needs, remove the thing of seed and Qi Nei.It should be noted that the seed of balsam pear inside and the thing of Qi Nei not necessarily will remove.Remove if wish inner thing, can clean after then removing.Be attached to seldom at foreign matter that situation on the balsam pear is next omits cleaning.To be cut into about 5 millimeters extremely about 15 millimeters thin slices and dry through pretreated balsam pear until quantity of residual from 10 to 5%.For the method for drying, suitable drying means can be used.For example, the very thin one deck of the balsam pear of thinly slicing is layered on the net under sunshine dry about 3 days, with dry they reach the scope of above-mentioned requirements.As a kind of method of replacement, the balsam pear of thinly slicing forces drying under such mode, and they stand temperature is 40 ℃ to 120 ℃ hot-air, by the time of the dry one section weak point of hot air drying machine.Through the dry balsam pear of crossing under the above-mentioned condition is the pitchy balsam pear tea that baking had fragranced in 3 to 15 minutes under 70 ℃ to 120 ℃ the iron plate with acquisition in temperature.

Following embodiment 1 implements under these circumstances to 3, the tea of the balsam pear production baking of thinly slicing by drying, drying is 40 ℃ to 120 ℃ at hot air temperature and uses hot air drying machine to carry out, and temperature by 70 ℃ to 120 ℃ iron plate on baking step by step, use the automatic tealeaves baking oven of direct-fired heating to carry out during maximum temperature.Seed and inner thing are removed from balsam pear, clean then, and its weight is decided to be 100% after the section.Shown after the minimizing degree of weight (that is, degree of drying) each step after it that degree of drying and the relation of frying in shallow oil between the roasting time also show out.
