Description
Technical field:
The present invention relates to food deep processing, particularly a kind of processing method of black rice instant food.
Background technology:
Black rice is folk food, comes from the Tang Dynasty.Jiangsu, Liyang, Jintan and one band rural area, south, Anhui, whenever lunar calendar the eighth day of lunar month in April, have other to boil black rice with blueberry leaf more, have become custom.On Zhejiang Province, China, Jiangsu, Hubei, Hunan, Jiangxi, Anhui and other places, people are still retaining the lunar calendar and are eating this ancient custom of black rice April.Black rice is She's traditional food, and the She of Fujian, Zhe Nan ate in March three.Black rice mainly utilizes glutinous rice to contain that the higher and blueberry leaf juice of amylopectin easily makes in the painted principle of amylopectin.Within 2011, in protection of intangible cultural heritage cuisines are listed black rice by Fujian Province.
Black rice is a kind of atropurpureus glutinous rice, and peasant is that the leaf that gathers wild plant blueberry boils soup, uses boiled soup that glutinous rice is soaked to half a day, then pulls out to put in wooden rice steamer to cook and form.Approximately with one jin of leaf immersion 4-5 jin glutinous rice.But this processing method is not suitable for preserving, and is not suitable as travelling products or enters market, supermarket product.
One band existing black rice instant food in Jiangsu is produced a few days ago, and its processing method is:
1, blueberry leaf is cleaned, is produced soak: it is to filter out soak after blueberry leaf is boiled to soup that soak is produced one, and another kind is to filter out soak after adding normal-temperature water to pulverize blueberry leaf.
2, glutinous rice soaks, drains: under normal temperature state, glutinous rice is placed in soak and soaks 12-24 hour, then drain.One jin of blueberry leaf can soak 4-5 jin glutinous rice, drains glutinous rice after referring to soak and is placed on screen pack after filtering and is without water droplet state.
3, thermophilic digestion: the glutinous rice draining is divided in high temperature polypropylene plastics pocket and vacuumizes rear sealing, put into the boiling of HTHP pot, boiling 30-40 minute, temperature reach 121 ℃, air pressure 102.9KPa.
4, cooling: after boiling, to take out and carry out air-cooledly or naturally cooling, be finished product after cooling.
This high temperature process method is mainly that the glutinous rice after soaking is well filtered to cleaning, and moisture is drained, and black rice is about 43-45%, pack high temperature sterilization, and rice water content is fixing because of packaging plastic bags, can not add water in bag again.If added water, 12% can cause the bottom of retort pouch can become rotten like this, has a strong impact on quality, does not add water because water content is fixed, black rice rehydration time is elongated, and because grain of rice internal moisture is less, the outer water content of the grain of rice is excessive, cause the gradation of moisture excessive, thereby make skin too swelling, after starch granules breaks, active ingredient stripping is too much, between the grain of rice, produce and stick with paste liquid, occur that quality is soft rotten, the phenomenon that mouthfeel is poor, even also there is hard-core in inside.The product of a thermophilic digestion can only be soaked boiling again on eating method, and there will be phenomenon recited above.Cannot directly add water edible by the method for frying, because of water content very little, the grain of rice is too hard, also should not be edible with microwave-oven-heating.
Summary of the invention:
The object of the invention is to overcome above-mentioned weak point, a kind of processing method of black rice instant food is provided.
The solution of the present invention is: comprise that 1. step clean, produce soak; 2. soak, drain; 3. thermophilic digestion; 4. cooling; It is characterized in that: step 3. thermophilic digestion be divided into open type thermophilic digestion, in three of the encapsulation of cold water conservation, packaged type thermophilic digestion step by step, open type thermophilic digestion is that the glutinous rice draining is placed in some dies and carries out open type thermophilic digestion, thermophilic digestion is that temperature is equal to or higher than 121 ℃, air pressure and is equal to or higher than boiling 10-15 minute under 102.9KPa condition, and backed off after random boiling; In the encapsulation of cold water conservation be several packaging bags of packing after exiting the glutinous rice of boiling and being cooled to 60-90 ℃, vacuumize rear sealing; Packaged type thermophilic digestion is that the packaging bag of packing glutinous rice is carried out to thermophilic digestion again, and thermophilic digestion is that temperature is equal to or higher than 121 ℃, air pressure and is equal to or higher than boiling 20-30 minute under 102.9KPa condition.
The invention has the advantages that: secondary high-temperature encapsulation cooking process makes finished product glutinous rice water content reach 55-57%, and rehydration, mouthfeel improve.
The specific embodiment:
Prior art drains rear encapsulation boiling water content and is fixed on the 43-45% draining, and the present invention drains open type thermophilic digestion of rear elder generation makes glutinous rice in the time of boiling, absorb moisture content; Then just middle cold seal fills, and middle cold finger is cooled to 60-90 ℃ and encapsulates rather than be cooled to normal temperature, and when 60-90 ℃ of encapsulation, glutinous rice water content reaches 55-57%, declines, so cold water conservation encapsulation in crying if be cooled to normal temperature water content; In secondary high-temperature retort pouch, high moisture recoverable amount can not run off.The raising of glutinous rice water content is crux point of the present invention.
Concrete preparation method is:
1, the fresh leaf of choosing blueberry cleans, and after cleaning, adds 1500-2500g normal-temperature water to pulverize according to pulverizing in 300-500g leaf process;
2, broken blueberry leaf and water are carried out to screen filtration, the ratio that the extract after 300-500g leaf is filtered soaks 2000-2500g glutinous rice, water temperature is controlled at 20-35 ℃ of following about 12-24 hour of immersion;
3, the glutinous rice after soaking is well filtered to cleaning, moisture is drained, black rice water content is about 43-45%;
4, the glutinous rice after draining is distributed in several dies that are of a size of 12 × 12cm, dark about 2cm, puts into autoclaving pot and carry out boiling, the condition of boiling is 121 ℃ of temperature, air pressure 102.9KPa time 10-15 minute;
5, after cooling a little, pack in fire resistant polypropylene polybag, refer to be cooled to 60-90 ℃, vacuumize rear sealing machine sealing:
