CN100999706A - Process of making aromatic vinegar by banana - Google Patents

Abstract

The invention discloses a method for producing balsamic vinegar from bananas. The production method is as follows: banana peeling→beating→enzymolysis→pomace separation→liquid alcohol fermentation→secondary wine fermentation→adjustment of alcohol content→acetification→clarification Filtration → aging → canning sterilization. The balsamic vinegar prepared by the present invention does not need to add any additives, and relies entirely on the fermentation process to increase the aroma of the balsamic vinegar. The aroma components are more than twice that of the liquid fermentation product under the same fermentation conditions, and can be formulated into banana balsamic vinegar. Deployed into acetic acid drinks. The balsamic vinegar contains about 30 kinds of volatile aroma components, and also contains nutrients such as glucose, fructose, galactose, malic acid and citric acid. Flavor is welcomed by people, the consumption of fruit vinegar and acetic acid drinks will continue to increase, and the market prospect is very broad.

Description

A kind of method of utilizing banana to make aromatic vinegar

Technical field

The present invention relates to a kind of making method of aromatic vinegar, specifically is a kind of method that is raw material through special zymotechnique making banana aromatic vinegar with the banana, belongs to food processing field.

Background technology

Banana belongs to fruit tree in many tropical and subtropical countries, but four seasons product really, and in recent years, China's banana production development is swift and violent, and cultivated area reaches 26.5 ten thousand hectares, accounts for 23% of national fruit total cultivated area, and output reaches 6,050,000 tons, and its industry gross output value reaches more than 100 hundred million yuan.But because banana storage tolerance not is difficult to transportation, very easily rotten, it is unsalable to meet prosperous product slightly, loses very seriously, and banana post-harvest loss rate be higher than the average loss rate 25% of China's postharvest fruit and vegetable far away, and developed country only has 5% up to nearly 50% in recent years.Along with the reduction of China and Association of South-east Asian Nations's agricultural tariff, import increases, and production and marketing contradiction will be more sharp-pointed, so the deep process technology of banana has become the task of top priority in banana producing region.Banana is called as happy food, contain mineral substance and various VITAMIN such as rich in protein, lipid, sugar, robust fibre and phosphorus, calcium, iron, potassium, sodium, have multiple physiological function such as relax bowel, vinegar can appetizing, nourishing the liver, nourishing the muscle and tendon, warm blood, sober up, help digestion, the therapeutic method to keep the adverse qi flowing downward exorcises evil spirits and separates all poison.Modern medicine and food expert studies have shown that fruit vinegar is with health role, can eliminate or lessen fatigue; The effect that has the arteriosclerosis of preventing and bring high blood pressure down; Also have the gastrointestinal health effect, acetic acid can stimulate gastric secretion, promotes food digestion, strengthens people's appetite, prevents gastroenteropathy, promotes stomach health.In addition, can also promote that the skin surface cellular metabolism is normal, play beautification function by reducing peroxide lipid material in the human body; To the replenishing of calcium in the bone, play strong bone effect or the like by calcium ion.And the banana aromatic vinegar is top grade in the fruit vinegar, has both had the function of general vinegar, has also kept the multiple nutritional components of banana, is a kind of senior seasonings and protective foods, can be directly used in the dish seasoning, also can be deployed into the acetic acid nourishing drink.At present, the fruit vinegar product on the China market is less, and its making method also mostly adopts liquid fermentation method, and liquid fermentation method making aromatic vinegar is serious to the loss of aroma of former fruit, is that raw material production high-quality fruit vinegar yet there are no report with the banana.

Summary of the invention

The objective of the invention is to disclose a kind of method that adopts the fermentation of reflux liquor legal system to make the banana aromatic vinegar, to overcome liquid fermentation method to the serious defective of former fruit aroma loss.

The present invention completes by following steps:

Banana peeling → making beating → enzymolysis → pomace separation → liquid phase process zymamsis → secondary fermentation of reflux liquor → adjustment wine degree → acetic acidization → clarification filtration → ageing → canning and sterilizing.

The aromatic vinegar that the present invention makes does not need to add any additives again, rely on fermenting process to increase the fragrance of aromatic vinegar fully, show through efficient liquid phase chromatographic analysis, volatile flavor compounds in the banana aromatic vinegar increases effect and is showing very much, and flavour ingredient (total ester content) is more than 2 times of liquid fermentation method product under the equal fermentation condition.
