Abstract

The invention discloses a processing method for natural dried pawpaw slices. The processing method for the natural dried pawpaw slices comprises concentrating sugar water to enable the sugar degree to be at 35 degrees BX (Brix), cooling the sugar water, adding citric acid, malic acid and potassium sorbate to be completely dissolved in the sugar water, adding dried pawpaw slices and maintaining the temperature to be between 25 and 28 DEG C to perform sugar soaking; adding sugar every day until the sugar degree is detected to achieve 35 degrees BX, fishing up the pawpaw slices and draining the sugar water; putting the sugar water drained pawpaw slices into a drying machine, drying for 16 to 20 hours at the temperature of 48 to 52 DEG C, turning sides, continuing drying at the temperature of 70 to 75 DEG C until the water content is between 13.5 and 15 %, adding oblatum powdered sugar and packaging to obtain finished products. The processing method for the natural dried pawpaw slices has the advantages of enabling the natural taste of pawpaw slices to be maintained, enabling original nutrient values to be greatly improved, enabling fragrance and crisp sweet tastes of the pawpaw slices to be improved and being easy to store and beneficial to extension of guarantee period.

Description

A kind of processing method of natural pawpaw dry plate

Technical field

The present invention relates to the preparation field of preserved fruit, specifically a kind of processing method of natural pawpaw dry plate.

Background technology

Pawpaw, formal name used at school is Chaenomeles pawpaw, has another name called wrinkled papaya, pawpaw, gap melon etc., is the fruit of rosaceae chaenomeles plant chaenomeles lagenaria, mainly is grown in the area, mountain area of subtropical zone warm and moist.On Guangdong, Hainan and other places, pawpaw also is called as papaw, has very high nutritive value and medical value.

Pawpaw nutrient is abundant, and taste is fresh and sweet.Measure according to modern science, be rich in vitamin A, B1, B2, C in pawpaw, mineral matter iron, calcium, potassium also contain natural plant polyose, protein, Fructus Chaenomelis ferment and organic acid.Wherein 17 contained seed amino acids have comprised whole essential amino acids, and ratio is near human body protein; Phosphorus, potassium content are also higher; Vitamin A and ascorbic content are watermelon and banana 5 times.Major physiological active material-oleanolic acid in pawpaw; approximately contain 0.1% left and right in the pawpaw fresh fruit; it have reduce transaminase activity, anti-inflammatory antibacterial, promote fat regeneration, prevent cirrhosis, reducing blood lipid blood sugar, cardiac stimulant, diuresis, anti-ageing, strengthen the effect such as immunity, and chromosome damage is had good protective effect.Pawpaw contains carrotene, and this polyphenoils makes pulp become crocus, and the infringement that causes of environmental contamination reduction.Pawpaw also is rich in beta carotene, and the oxidation that this natural antioxidant can effectively resist systemic cell destroys making human body accelerate old and feeble oxygen radical.Therefore, often eat the effect that pawpaw also has beauty and skin care, delays senility.

Chinese patent 201210249383.7 discloses a kind of processing method of combination drying papaya sheet, after look is protected in raw material peeling section, first carrying out heated-air drying to water content is 30-60%, then to carry out micro-wave vacuum to water content be 5-8%, gets product after cooling packing.The method destructible pawpaw nutrition composition originally, and in a single day it is edible to open bag, and pawpaw does and easily sticks together, and affects mouthfeel and shelf-life.

Summary of the invention

Technical problem to be solved by this invention is, deficiency for above-mentioned prior art existence, a kind of processing method of natural pawpaw dry plate is provided, what can keep that pawpaw does is natural flavour mountaineous, its original nutritive value is improved greatly, can increase again its fragrance and crisp sweet mouthfeel, easily preserve, and help and extend the shelf life.

The present invention solves the problems of the technologies described above the technical scheme of taking: a kind of processing method of natural pawpaw dry plate, and step is as follows: (1) selected pawpaw raw material, (2) peeling, (3) section, mix (4), and (5) sugar soaks, (6) oven dry, (7) upper Icing Sugar, (8) packing;

The concrete grammar of described step (4) is: when syrup is concentrated to pol and is 35 ° of BX with thickener, the 18-22% that presses raw material weight calculates required liquid glucose, cooling, add 0.25-0.30% citric acid, 0.11-0.15% malic acid, 0.04-0.6% potassium sorbate and 0.10-0.12% sodium pyrosulfite, be dissolved in fully in syrup, obtain mixing syrup;

The concrete grammar of described step (5) is: the pawpaw that will cut into slices adds in the mixing syrup of step (4) gained, and holding temperature is carried out sugar at 25-28 ℃ and soaked; Sugaring every day picks up papaya tablet to detecting when pol reaches 35 ° of BX, is tiled on the oven dry sieve and drains syrup;

The concrete grammar of described step (6) is: the papaya tablet that will drain syrup is put into dryer, and first with 48-52 ℃ of baking 16-20 hour, then turn-over continues oven dry with 70-75 ℃, to water content be 13.5-15%;

The concrete grammar of described step (7) is: the papaya tablet after drying carries out cooling with cold wind, sprinkle equably the wafer Icing Sugar, then the papaya tablet of first-class wafer Icing Sugar is put into storage cell.

The present invention can either keep the natural flavour mountaineous of pawpaw, and original nutritive value is improved greatly, and has sweet crisp mouthfeel, greatly increases people's appetite, and is conducive to human body to the absorption of pawpaw nutrient composition.Upper wafer Icing Sugar can keep product soft, and dry tack free is not clamminess, and improves flavour of food products and color and luster, improving product class, the mouthfeel of increase food; Instant is easily preserved long shelf-life.

Description of drawings

Fig. 1 is the processing method process chart of natural pawpaw dry plate of the present invention.

The specific embodiment

Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.

As shown in Figure 1, a kind of processing method of natural pawpaw dry plate, concrete steps are as follows:

(1) selected pawpaw raw material: Chaenomeles Cultivars is more, differ greatly each other, must be noted that when choosing that two select: the one, must be the fruit pawpaw, the color of the pawpaw meat heart is different, the finished color of producing is also different, in order to reach the effect of edible lovely luster partly, should select to purchase the pawpaw of gold zone; The 2nd, the water content of pawpaw is different, the moisture height increase cost of material, business efficiency is poor, the good water content of the pawpaw GPRS of purchase; Should note simultaneously pawpaw be easy fragmentation, easily go mouldy, perishable material, want strict selecting before cleaning, remove and go mouldy, rot and overdone pawpaw, in order to avoid affect quality and mouthfeel;

(2) peeling: peeling after pawpaw is cleaned;

(3) section: every thickness 1cm left and right, sugared effect is soaked in thick impact, easily rots during thin dipping, affects yield;

(4) mix: when syrup is concentrated to pol and is 35 ° of BX with thickener, press the 20% required liquid glucose of calculating of raw material weight, be discharged in treating tank, cooling, 0.25% citric acid, 0.12% malic acid, 0.06% potassium sorbate and 0.1% sodium pyrosulfite are dissolved in syrup fully, obtain mixing syrup;

(5) sugaring: the pawpaw that will cut into slices adds and mixes in syrup, above then being pressed in food-grade net and the pole that disinfects, prevents the hair bleaching ferment; Temperature is maintained 25-28 ℃ carry out sugar and soak, will ventilate in the process of dipping; It is full that sugar is eaten in sugaring every day to detection, picks up papaya tablet when reaching 35 ° of BX of pol, is tiled on the oven dry sieve and drains syrup;

(6) oven dry: the papaya tablet that will drain syrup is put into dryer, and first with 50 ℃ of bakings 18 hours, then turn-over continues oven dry with 70-75 ℃, to water content be 14%;

(7) upper Icing Sugar: dried to pawpaw with powder on 0.05% wafer Icing Sugar that the pawpaw of oven dry is dried is in addition cooling with cold wind after pulling out, high the choosing of moisture dried by the fire again, the papaya tablet of first-class wafer Icing Sugar is poured into and is put into storage cell in basket;

(8) packing gets product.
