Abstract

The invention discloses a kind of freeze-dried fructus momordicae sheet and preparation method thereof, belong to food processing technology field.Described freeze-dried fructus momordicae sheet through selecting, cut into slices, completing, the freezing of natural air drying, precooling, secondary, the technique such as Deep-Frozen is prepared.Compared with prior art, the inventive method technique is simple and easy to control, and sublimation drying is short, and energy consumption is low, and production efficiency is high;Hot water is used to complete technology, the activity of the enzymes such as the polyphenol oxidase being passivated in arhat peel, by three refrigerating process, moisture in Fructus Momordicae is made to volatilize in order, avoid because moisture drying causes peel to separate with sarcocarp, well maintain the color and luster of Fructus Momordicae, fragrance, mouthfeel and nutritional labeling etc. simultaneously.

Description

A kind of freeze-dried fructus momordicae sheet and preparation method thereof
Technical field
The invention belongs to food processing technology field, be specifically related to the preparation method of a kind of freeze-dried fructus momordicae sheet, further relate to Use the freeze-dried fructus momordicae sheet that the method is prepared.
Background technology
Fructus Momordicae, the fruit of the perennial liana of Cucurbitaceae.Another name LAHANGUO, Herba Cardiospermi Halicacabi, Semen Momordicae, Radix Stephaniae Sinicae (Radix Stephaniae Dielsianae), Arhat table, naked Testudinis bar, be described as " angle fruit " by people, and its leaf is heart-shaped, dioecism, summer-flowering, seed in autumn.Mainly originate in Longjiang township, Yongfu county, hazard prevention, dragon victory and hundred Shou Deng towns, He Longsheng county, Yongfu county is that township's plantation history of Fructus Momordicae compares Long, wherein plantation Fructus Momordicae in Yongfu has had more than 300 year history, Long Sheng county plantation Fructus Momordicae to have more than 200 year history, in State 90 percent Fructus Momordicae originates in He Longsheng county, Yongfu county, and Fructus Momordicae is the local and special products that Guilin is famous and precious, is also first batch of batch of country One of accurate medicine-food two-purpose material, its primary efficacy is can relieving cough and resolving phlegm.Fruits nutrition is worth the highest, containing abundant vitamin C (containing 400 milligrams~500 milligrams in every 100 grams of fresh fruits) and glucoside, fructose, glucose, protein, lipid etc..
The storage phase of new fresh Fructus Momordicae is shorter, less than 20 days.People are processed as dry product to improve arhat by employing The storage period of fruit.Existing Fructus Momordicae dry products manufacturing technology mainly by three kinds, i.e. hot-air seasoning, microwave vacuum drying and vacuum Drying bu sublimation.The advantage of hot-air seasoning is that energy consumption is low, and shortcoming is that nutrient loss is serious, Fructus Momordicae surface drying shrinkage, shape Shape is poor, variable color etc..Microwave vacuum drying, made dry product color keeps good compared with hot air drying, but nutrient loss is more Seriously.
Summary of the invention
For the deficiencies in the prior art, the invention provides the preparation method of a kind of freeze-dried fructus momordicae sheet, the method can be relatively Keeping well the color of Fructus Momordicae, shape and nutritional labeling, production efficiency is high, easy and simple to handle.Invention also provides logical Cross the freeze-dried fructus momordicae sheet that the method prepares.
Concrete, the preparation method of freeze-dried fructus momordicae sheet of the present invention, comprise the following steps:
(1) choosing maturation, disease-free, non-rot fresh Fructus Momordicae, clear water is cleaned;
(2) the Fructus Momordicae section after step (1) being cleaned, slice thickness controls at 1-2cm;
(3) Fructus Momordicae after step (2) being cut into slices is placed in the water of 80~90 DEG C and completes 3~5min;
(4) Fructus Momordicae after step (3) being completed be placed in 10~20 DEG C under conditions of natural air drying 2~3h;
(5) being placed in freeze dryer by the Fructus Momordicae after step (4) natural air drying, cooling, is-20~-10 being down to temperature DEG C time precooling 5~8h;It is 0.5~1h by the time of room temperature near precooling temperature;
(6) by the Fructus Momordicae after step (5) precooling in temperature for-30~-20 DEG C, vacuum be under conditions of 30~50Pa two Secondary freezing 3~5h;
(7) by the Fructus Momordicae after step (6) secondary freezing in temperature of heating plate be 25~35 DEG C, vacuum be 30~50Pa, cold Trap temperature be-30~-35 DEG C under conditions of Deep-Frozen 5~8h;
(8) by the Fructus Momordicae vacuum sealed package after step (7) Deep-Frozen, freeze-dried fructus momordicae sheet finished product is obtained.
Further illustrating as the present invention, in described step (2), slice thickness controls at 1.5cm.
Further illustrating as the present invention, in described step (4), natural air drying under conditions of temperature is 14~16 DEG C 2.5h。
Further illustrating as the present invention, in described step (5), temperature be-16~-14 DEG C under conditions of precooling 6h。
Further illustrating as the present invention, in described step (6), temperature for-26~-24 DEG C, vacuum be 35~ Secondary freezing 4h under conditions of 45Pa.
Further illustrating as the present invention, in described step (7), temperature of heating plate be 28~32 DEG C, vacuum be 35~45Pa, condenser temperature be-32~-33 DEG C under conditions of Deep-Frozen 6h.
Meanwhile, the invention provides the freeze-dried fructus momordicae sheet using said method to be prepared.
The inventive method technique is simple and easy to control, and sublimation drying is short, and energy consumption is low, and production efficiency is high;Employing hot water completes Technology, the activity of the enzymes such as the polyphenol oxidase being passivated in arhat peel, by three refrigerating process, make moisture in Fructus Momordicae have Sequence is volatilized, it is to avoid because moisture drying causes peel to separate with sarcocarp, well maintains the color and luster of Fructus Momordicae, fragrance, mouth simultaneously Sense and nutritional labeling etc..
