Summary of the invention
The invention provides the preparation method of a kind of anthocyanogen lemonade tablet, anthocyanogen lemon vinegar and anthocyanogen lemon vinegar beverage, not only sweet mouthfeel is moderate, color is tempting for the anthocyanogen lemon vinegar beverage that the method prepares, nutritious but also anthocyanogen can stable existence in beverage, beverage long quality-guarantee period.
A preparation method for anthocyanogen lemon vinegar, comprises the following steps:
(1) Rhizoma Dioscoreae esculentae is cleaned, peeling, to cook after section and dry, obtain Rhizoma Dioscoreae esculentae sheet;
(2) Rhizoma Dioscoreae esculentae sheet is placed in light-coloured vinegar lixiviate, obtains vat liquor;
(3) by described vat liquor with remove the lemonade tablet of seed, sweeting agent mixes, and takes out lemonade tablet, centrifuging and taking supernatant liquor after immersion, obtains anthocyanogen lemon vinegar.
Anthocyanogen is one of flavonoid compound that higher plant secondary metabolism produces, and anthocyanins pigment from purple sweet potato imparts Rhizoma Dioscoreae esculentae red-purple and special functional, makes it be different from Ordinary Sweet Potatoes.Often edible Rhizoma Dioscoreae esculentae obviously can strengthen human immunological competence, antimutagenic effect, alleviates hepatic dysfunction, have good prevention effect to digestive tube and cardiovascular and cerebrovascular diseases, and its anti-cancer and cancer-preventing ability occupies first of various food.Usually, the poor stability of anthocyanogen, reason is the high reactivity of its constitutional features and aglycon.Anthocyanogen is formed through β-glycosidic link with sugar by aglycon and anthocyanidin; Anthocyanidin is exist with glycosylated form at occurring in nature, namely glycosides is become, greatly strengthen its stability in aqueous, but cyanin glycosidic link is very easily hydrolyzed, the flavylium ion of anthocyanidin mutter core because being in electron deficiency state high activity, be subject to nucleophillic attack, therefore anthocyanogen finished product is always tending towards the structural changes of degraded fast, its stability is vulnerable to various factors, as self structure and concentration; Environment pH, temperature and light shine; Enzyme, oxygen and metal ion etc.
The present invention by cooking, the mode such as light-coloured vinegar lixiviate directly extracts anthocyanogen, and soaks with the anthocyanogen that with the addition of saccharosan the lemonade tablet removing seed from Rhizoma Dioscoreae esculentae, obtains stable anthocyanogen lemon vinegar beverage.This saccharosan is commonly called as rock sugar.
In the leaching process of conventional anthocyanogen, after Rhizoma Dioscoreae esculentae cleans defibrination, be directly dissolved in acidifying organic solvent, carry out lixiviate, the effect not only extracted is bad, and this extracting mode can not be used for eating.
In the process that Rhizoma Dioscoreae esculentae is steamed by water vapor, the structure organization of Rhizoma Dioscoreae esculentae becomes comparatively loose, is beneficial to the extraction efficiency of anthocyanogen in follow-up light-coloured vinegar immersion process; And the process that water vapour steams is different from digestion process, Rhizoma Dioscoreae esculentae and large quantity of moisture can not be made to contact with each other, avoid the anthocyanogen in digestion process Rhizoma Dioscoreae esculentae to be dissolved in water, cause the loss of anthocyanogen composition; In addition, by enzyme deactivations such as the oxydase in Rhizoma Dioscoreae esculentae, the beverage taste problem that Rhizoma Dioscoreae esculentae causes because of brown stain can be avoided in the process that water vapor steams.After above-mentioned water vapor steaming is ripe to Rhizoma Dioscoreae esculentae, the general time is at 20 ~ 30min.
