Description
Technical field
The present invention is a kind of preparation method of freshness-retaining vegetable, is specially adapted to the preparation method of removing the peel onion.
Background technology
Onion has another name called round onions, onion, Onion, ball green onion, unit green onion is described as " in dish queen " in Europe, its rich in nutrition content, except not fatty, containing protein, sugar, crude fibre and calcium, phosphorus, iron, selenium, carrotene, thiamine, riboflavin, niacin, the multiple nutritional components such as ascorbic acid, about water content 88g in the every 100g of fresh onion, protein 1.1g, carbohydrate 8.1g, crude fibre 0.9g, fat 0.2g, ash content 0.5g, carrotene 0.02mg, vitaminB10 .03mg, vitamin B2 0.02mg, vitamin C 8mg, vitamin E 0.14mg, potassium 147mg, sodium 4.4mg, calcium 40mg and selenium, zinc, copper, iron, the various trace elements such as magnesium.Onion, except containing except general nutrient, also waits bioactivator containing sterilization diuresis blood fat-reducing blood pressure-decreasing is anticancer.Allicin in onion and multiple sulfur-containing compound can kill various bacteria and fungi within a short period of time; Some biological activity in onion can promote that in body, sodium water is discharged and tool diuresis from kidney; Onion oil has the effect reducing blood fat; In onion the K factor (ratio of potassium/sodium) higher (33.42) and containing can vasodilator, alleviate periphery and coronary vascular resistance, antagonism catecholamine material PGA1 and present the effect reduced blood pressure; The tolbutamide contained in onion has and falls hypoglycemic effect; In onion, selenium content is higher has antitumaous effect etc.Clinical medicine and research in recent years proves, onion has multiple higher physiology medical value, nutrition dietary cure is praised highly for the anticancer nutritional health food of multi-functional blood fat-reducing blood pressure-decreasing, enjoy the laudatory title of " in dish queen ", onion is the nutrition of a kind of collection, medical treatment and health care Specialty vegetable, onion high nutritive value, in the bulb of its hypertrophy sugary 8.5%, dry 9.2%, every 100 grams contain vitamin A 5 milligrams, vitamin C 9.3 milligrams, calcium 40 milligrams, 50 milligrams, phosphorus, iron 8 milligrams, and 18 seed amino acids, it is rare health food, through the clinical proof of traditional Chinese and western medicine: onion has flat liver, the function of ease constipation, material---the diallyl disulfide reducing cholesterol is had in volatile oil contained by it, be current only prostaglandin-containing sample material and blood yield of fibrinolytic enzyme composition can be activated, these materials all have stronger vasodilator and the ability of heart coronary artery, the excretion of sodium salt can be promoted again, thus blood pressure is declined and antithrombotic, modern medicine research also shows, containing trace elements of selenium in onion.Selenium is a kind of antioxidant, and its special role to make human body produce a large amount of glutathione, and the physiological action of glutathione is that delivering oxygen supplies cellular respiration, and in human body, Se content increases, and cancer incidence will decline greatly.So onion is again a kind of health food, and onion also has hypoglycemic activity, because containing and organic matter like hypoglycemic agent first sulphur fourth pulse-phase in onion, and the skin bitter principle with powerful diuresis can be generated in human body.The every canteen onion of diabetic 25 ~ 50 grams can play the effect reducing blood sugar and diuresis preferably, phytocide in onion stimulates appetite except having, help digest except effect, also due to it via respiratory tract, the urinary tract, sweat gland discharge time, duct wall can be stimulated to secrete, thus eliminate the phlegm again, diuresis, sweating, preventing cold and antibacterial corrosion-resistant effect.
Summary of the invention
Export peeling onion a preparation method, with the bulb of onion for raw material, carry out as follows:
(1) select the applicable kind of yellow onion as processing of removing the peel processing, mid-May gathers, and stops the water that applies fertilizer in the last week of gathering, and the object of stopping fertilising water executes onion minimizing water content;
(2) onion of gathering is selected meet that export processing wants by diameter classification, braiding is stored under being placed on 30-35 DEG C of temperature together with cauline leaf, storing object together with cauline leaf is make the nutrient of cauline leaf continue to carry to onion bulb in the process of storage, serve afterripening, 30-35 DEG C of high-temperature storages can delay the rest period of onion, and the onion in rest period does not germinate, storage endurance;
(3) onion stored is cut cauline leaf and be placed on sterilization in bactericidal liquid, sterilizing time is 15 to 20 minutes, bactericidal liquid with water, chlorine dioxide, citric acid by weight; Water: chlorine dioxide: citric acid=100:0.024 to 0.026:0.12 is formulated to 0.14, onion can contain a large amount of microorganisms at soil-grown and in storage ambient, be necessary to carry out sterilization to raw material, chlorine dioxide is efficient germicide, bactericidal effect is stronger in acid condition, and it is residual that next procedure wants peeling to so there is no any chlorine residue to onion;
(4) will kill the onion excision root base of a fruit of bacterium, and peel off Lao Pi, it is complete that peeling will shell onion ball smooth surface, and mechanical is hindered, without mildew, till free from insect pests;
(5) onion shelling skin is placed on sterilization in bactericidal liquid, sterilizing time is 3 to 5 minutes, bactericidal liquid is with water, clorox, VC, by weight: water: clorox: VC=100:0.005 to 0.007:0.11 is formulated to 0.13, this operation is semi-finished product sterilizations, add in bactericidal liquid excessive VC can in and chlorine residue, eliminate chlorine smelly, make the residual of chlorine residue reach export requirement;
(6) vacuumize in the onion of (5) gained loading polybag, refrigerate finished product of ascending the throne under putting into 0-5 DEG C of temperature and remove the peel fresh-keeping onion;
With the peeling onion that said method is produced, through 30-35 DEG C of high temperature storages raw material, sterilization, semi-finished product sterilizations, vacuumize, store at 0-5 DEG C of temperature, the rest period of onion is extended by high-temperature storage, peeling final vacuum packaging deepfreeze, product nutritional labeling is destroyed few, maintains the original nutritive value of fresh onion, microbiological indicator reaches export requirement, and product can store 90 days.
