Abstract

The invention belongs to the technical field of food processing technology and in particular relates to a method for making transparent preserved sweet potato. The method mainly comprises the following steps: selecting a material; slicing the material; throwing slices into prepared color protecting and hardening liquid and soaking the slices for 10 hours, wherein the color protecting and hardening liquid comprises the following components by percentage: 0.3 percent of citric acid, 0.2 percent of sodium bisulfite, 0.2 percent of calcium chloride and 1 percent of honey; washing; saccharifying; roasting and packaging. The transparent preserved sweet potato prepared by the method has excellent color, aroma and taste, rich nutrition, wide processing materials, low cost, salability in market and high economic benefit, and is particularly suitable for family processing.

Description

The preparation method of transparent preserved sweet potato

Technical field: the invention belongs to food processing technology field, be specifically related to a kind of method of processing transparent Ipomoea batatas dried meat.

Background technology: the Ipomoea batatas heat content is low, has much satiety again, no matter is as staple food or non-staple foodstuff, all is a kind of good diet food.According to surveying and determination, per 100 gram Ipomoea batatas are fatty only to be 0.2 gram, is the % of rice.Therefore Ipomoea batatas is the outstanding person in low in calories, the low-fat food.In addition, Ipomoea batatas also contains balanced nutrition.As vitamin A, B, C, plant trace element surplus cellulose and potassium, iron, the copper etc. 10, wherein cellulose plays good spread effect to intestines peristalsis, promotes to drain unimpeded.Simultaneously, because fibre structure can't be absorbed, the specific function that obstructs carbohydrate to become fat is arranged in enteron aisle.So the nutritionist claims that Ipomoea batatas is the best balanced health food of nutrition, also be ideal and spend little fat-reducing food.Just because of Ipomoea batatas is cheapness and obvious results fat-reducing " good medicine ", Ipomoea batatas enjoys green grass or young crops to narrow abroad again in recent years.The Japanese as a kind of " delicious healthy food ", even also has baked batata baked batata to sell in the big hotel of Tokyo, Osaka.It is the ice cream made of raw material, dessert, candy etc. that the occidentals also designs with the Ipomoea batatas.In some restaurants, eating bread can be free, eat Ipomoea batatas but pay in addition.

The Ipomoea batatas sweet property of distinguishing the flavor of is flat, is a kind of cheap and good-quality health food, makes people's longevity, has effects such as qi-restoratives is weary, beneficial strength, the taste of holding concurrently, strong kidney yin.Ipomoea batatas is one of best balanced food of nutrition, and 500 gram Ipomoea batatas can produce 630 kilocalories of heats, contain protein and surpass rice, fine flour and millet, also contain calcium, phosphorus, iron, carrot and vitamin.Especially valuable iron, the calcium that is in the flour to be lacked, carrot and vitamin C, and all abundanter in the Ipomoea batatas.Vitamin C in the Ipomoea batatas can match in excellence or beauty with oranges and tangerines, and Cobastab is 7 times of rice.Ipomoea batatas has remarkable inhibition effect of malignant tumors, in 20 kinds of vegetables according to the announcement of the pre-research institute of Japanese cancer, and the Ipomoea batatas seniority among brothers and sisters umber one.Has the effect that keeps vessel wall elasticity simultaneously; Prevent the effect of internal organs adesmosis; Improve the effect of body immunity; Anti-constipation effect; Anti-coronary heart disease effect; Prolong old and feeble effect; The effect of promoting longevity.Ipomoea batatas is rich in dietary fiber, can prevent constipation, treatment hemorrhoid and anal fissure.The dehydroepiandrosterone that institute's water content is called as " imitative hormone " can effectively suppress breast cancer and colon cancer.The human organ mucous membrane there is special protective effect, can keeps blood vessel elasticity, prevent the adesmosis in the liver kidney.Still be desirable diet food simultaneously, have the specific function that the prevention sugar is converted into fat.

Summary of the invention: purpose of the present invention proposes a kind of suitable preservation exactly, again the preparation method of the transparent Ipomoea batatas dried meat of good mouthfeel.

The present invention is achieved like this: select materials: fully ripe, smooth potato piece full, that be of moderate size is cleaned peeling; Section: can be block-shaped during section according to potato, slitting or garden sheet, and suitably finishing drop into protecting in look and the hardening bath of having prepared then and soaked 10 hours.The best proportioning of protecting look and hardening bath is 0.3% citric acid, 0.2% sodium hydrogensulfite, 0.2% calcium chloride, 1% honey; Flushing: will pull out through protecting the French fries (sheet) that look and hardening bath handle well. with the clear water flushing for several times, do not stay low-priced liquid, in order to avoid Maillard reaction takes place when candy; Candy: as to adopt three times candy method, 35% liquid glucose that is preparing, add people 30% lemon camphor tree acid adjust pH to 2.0-3.0, treat that liquid glucose boils after. the potato chips of handling well are fallen after people and adding a cover boils, open wide again to cover and boiled ten minutes, when boiling, we must add 1% honey, after candy, potato chips be placed on to protect in look and the hardening bath soaked 6 hours, method is candy again the 2nd time, the 3rd time according to this, sugar concentration is upgraded to 55%, 65% successively, at last sugar is soaked 1 times of time lengthening; Toast: the French fries (sheet) after sugar is soaked are pulled out. drop desaccharification liquid, evenly be placed on the bamboo mat, and to toast 8-10 hour down in 60-65 ℃, the centre is stirred once, dries by the fire to the potato piece tack-free. and water content is about 18% vannings; Packing: will dry by the fire the potato of getting well and remove the fritter of chip and not moulding late afternoon, and pack in the food bag of packing into and get final product.

The specific embodiment: the present invention is described in detail below in conjunction with embodiment.

Embodiment: select materials: fully ripe, smooth potato piece full, that be of moderate size is cleaned peeling; Section: can be block-shaped during section according to potato, slitting or garden sheet, and suitably finishing drop into protecting in look and the hardening bath of having prepared then and soaked 10 hours.The best proportioning of protecting look and hardening bath is 0.3% citric acid, 0.2% sodium hydrogensulfite, 0.2% calcium chloride, 1% honey; Flushing: will pull out through protecting the French fries (sheet) that look and hardening bath handle well. with the clear water flushing for several times, do not stay low-priced liquid, in order to avoid Maillard reaction takes place when candy; Candy: as to adopt three times candy method, 35% liquid glucose that is preparing, add people 30% lemon camphor tree acid adjust pH to 2.0-3.0, treat that liquid glucose boils after. the potato chips of handling well are fallen after people and adding a cover boils, open wide again to cover and boiled ten minutes, when boiling, we must add 1% honey, after candy, potato chips be placed on to protect in look and the hardening bath soaked 6 hours, method is candy again the 2nd time, the 3rd time according to this, sugar concentration is upgraded to 55%, 65% successively, at last sugar is soaked 1 times of time lengthening; Toast: the French fries (sheet) after sugar is soaked are pulled out. drop desaccharification liquid, evenly be placed on the bamboo mat, and to toast 8-10 hour down in 60-65 ℃, the centre is stirred once, dries by the fire to the potato piece tack-free. and water content is about 18% vannings; Packing: will dry by the fire the potato of getting well and remove the fritter of chip and not moulding late afternoon, and pack in the food bag of packing into and get final product.

The transparent potato dried meat of the inventive method preparation, color, smell and taste are feared good, and are nutritious.Process raw material extensively, cost is low to be examined, and is in great demand in market, and the economic benefit height is particularly suitable for family's processing.
