Description

A kind of preparation method of fresh yam
Technical field
The invention belongs to technical field of agricultural product process, specifically belong to Chinese yam fresh-keeping processing technology field.
Background technique
Chinese yam is the rhizome of Dioscoreaceae plant Chinese yam.Main product is in Henan, Hubei, Hunan, Hebei, Shanxi, Shaanxi and other places.In Doctor's habit thinks that Henan produces Chinese yam performance optimal, therefore practises and claim " RHIIZOMA DIOSCOREAE from Henan of China ".The produced Chinese yam in Hubei Li Shizhen (1518-1593 A.D.) native place is similar to palm, Therefore claim " fingered citron Chinese yam ".
Chinese yam is common tonic Chinese herbal medicine material, and medicinal history is long, first recorded in Shennong's Herbal, is listed in top grade." book on Chinese herbal medicine Detailed outline " five large effects, kidney-nourishing gas, strengthening the spleen and stomach, stopping leak dysentery, resolving sputum saliva, profit fur are summarised as, classics nourish prescription, such as six Taste Dihuang Wan, Qiju Dihuang Wan, shenling baizhu powder etc. all contain Chinese yam.Modern research shows that Chinese yam contains Dioscin, biology Alkali, mucilaginous substance, glycoprotein, active polysaccharide etc. have hypoglycemic, anti-aging, anti-oxidant, adjusting or strengthen immunity, adjustment intestines The functions such as stomach.
Chinese yam integration of drinking and medicinal herbs, delicate succulence, quality is crisp and refreshing, is loved by consumers as food materials, and foreign exchange earning produces One of product.The harvest season of fresh Chinese yam concentrates, and fresh yam moisture content is big, and the storability of stem tuber is poor and takes up a large area, It should not save for a long time and long distance transportation, " fingered citron Chinese yam " are more prominent.
For rational exploitation and utilization Chinese yam resource, numerous studies is carried out about Chinese yam, have also developed a system Column product, such as Chinese yam noodle, yam flour, quick freezed yam, yam drink, but safe and simple fresh yam preservation technology and production Product are not yet.There are some preservation methods at present, but uses sodium hypochlorite, sodium sulfite or sodium dichloroisocyanurate Strong oxdiative Agent is as color stabilizer color protection, although keeping Chinese yam not brown stain, the nutritive and health protection components of Chinese yam are oxidized destruction, fresh yam Do not have healthy nutritive value.It is exactly using water such as a kind of production method of fresh yam of patent of invention CN102318666B: VC: sodium dichloroisocyanurate=100:0.07-0.13:0.018-0.022 solution sterilization, again in water after peeling: sodium hypochlorite: VC Color protection in=100:0.07-0.13:0.014-0.016 solution.Except this, also there is the method using high level salt solution color protection, it is still, high Salt diet can cause the diseases such as cardiovascular and cerebrovascular, hypertension.As patent of invention CN104273215A uses raw material and water total weight 10- 18% salt is marinated, although can achieve color-protecting function, later period necessary desalination and salt content height are harmful to human health.
Summary of the invention
In order to overcome the shortage of prior art, the present invention using safety food additives, science compounding hypertonic solution (by First salt+second salt+sugar alcohol+water composition) color protection, then cooperate high temperature enzyme deactivation, it is vacuum-packed, the more Integration ofTechnologies of high temperature sterilization prepare fresh-keeping Chinese yam, can reach not only prevents brown stain, but also keeps the purpose of the nutritive and health protection components of Chinese yam to the maximum extent, and product normal temperature storage Transport stored, was convenient up to 12 months or more shelf-life.
For achieving the above object, the present invention provides following technical scheme
A kind of preparation method of fresh yam, it is characterised in that: steps are as follows:
1) fresh yam is removed the peel, rejects worm-eaten or mechanical wounding goes bad, change colour position;
2) peeling Chinese yam is cleaned up with flowing mountain spring water or tap water;
3) by clean yam slices or stripping and slicing;
4) yam slice or block are immersed rapidly in the hypertonic color protection solution being made of first salt A B, second salt C D2, sugared alcohol and water Color protection treatment,
Wherein:
A=K+,Na+
B=Cl-,IO3-, citrate, bicarbonate radical etc.;
C=Ca2+, Zn2+
D=Cl-, citrate, glucose acid group etc.;
5) yam slice after color protection treatment or block are put into boiling water bath quick blanching enzyme deactivation;
6) yam slice after blanching or block are rapidly cooled to close to room temperature;
7) it measures, is added or is added without fruit juice or fruit sauce, packed, vacuumized with aluminum foil bag, seal;
8) the Chinese yam high temperature sterilization that vacuum-pumping density is sealed;
9) after cooling, packaging bag free surface moisture is dried, is cased, storage, normal temperature storage.
According to the above scheme, the color protection time is 10-30min.
According to the above scheme, the blanching time is 2-5min.
According to the above scheme, 105 DEG C -115 DEG C of the high temperature sterilization temperature, sterilizing time 10-15 minutes.
According to the above scheme, the hypertonic colour protecting liquid by weight percentage by (0.1%-2.0%) first salt A B, (0.01%-1.0%) second salt C D2, (1%-6.0%) sugar alcohol and excess water composition.
According to the above scheme, first salt AB can be sodium chloride or potassium chloride or Potassiumiodate or sodium iodate or potassium citrate or lemon Sour sodium or saleratus or sodium bicarbonate;Second salt CD2 can be calcium chloride or zinc chloride or zinc gluconate or calcium gluconate or Zinc citrate or calcium citrate etc..
According to the above scheme, sugar alcohol be food additives, selected from xylitol, D-glucitol, L- mannitol, maltitol, One or both of hydroxyl isomaltulose.
According to the above scheme, Chinese yam raw material used is not only suitable for crisp Chinese yam, is also applied for powder Chinese yam, especially suitable fingered citron mountain Medicine.
According to the above scheme, gained fresh yam product can be the health food of eating as opening, be also possible to boil in the hotpot or The food materials of culinary art can also be used as the raw material of food processing.
According to the above scheme, fruit juice or fruit sauce is added, the health food of eating as opening, fruit juice or fruit is made Sauce can be original strawberry juice or strawberry, apple fumet or apple jam, pineapple Normal juice or pineapple jam, lemon juice or jam with lemon, indigo plant Certain kind of berries Normal juice or blueberry jam etc..
According to the above scheme, fresh-keeping Chinese yam is without refrigeration or cold storage, and the room temperature shelf-life was up to 12 months or more.
Beneficial effects of the present invention:
The main reason for Chinese yam brown stain is to contain polyphenol oxidase simultaneously containing a large amount of polyphenols in Chinese yam, by When mechanical damage or heat treatment, oxidation occurs and changes colour, by hypertonic solution color protection, then cooperates high temperature enzyme deactivation, is vacuum-packed, it is high Temperature sterilizes more Integration ofTechnologies and prepares fresh yam, can achieve the effect that prevent brown stain.Traditional preservation method is protected using high level salt solution Color, still, high salt diet can cause the diseases such as cardiovascular and cerebrovascular, hypertension.Such as patent of invention CN104273215A using raw material and The salt of water total weight 10-18% is marinated, although can achieve color-protecting function, later period necessary desalination and salt content height, to people Body health is unfavorable.Effect of color protection is not achieved in single low salt solutions again, and this patent uses first salt and the two distinct types of salt of second salt, Cooperate again with sugar alcohol, synergistic function forms hypertonic solution, makes enzymatic inactivation, while cooperating high temperature enzyme deactivation again, is vacuum-packed, high Temperature sterilizes more Integration ofTechnologies and prepares fresh yam, and can reach both prevents brown stain, edible safety, the room temperature shelf-life up to 12 months with On, without any toxic side effect, and the purpose of the nutritive and health protection components of Chinese yam is kept to the maximum extent, and reach target.
