The obtained cotrolled-oxidized product of fat can be used as a precursor of meat-taste essence, and can be made into meat-taste essence with stable quality by further thermal reaction. The method has such advantages as low energy consumption, easy cleaning and easy scale up for mass production.
Description
Technical field
The present invention relates to a kind of method that adopts gas lift type common loop reactor to prepare fat to control oxidation product, prepared fat to control oxidation product can be used as precursor of meat-flavour essence, and further reaction for preparation goes out meat flavour.
Background technology
Carbonyl containing compounds such as the small molecules aldehyde in the fats oxidn product, ketone are the important precursor of reaction for preparation meat flavour, these small molecules aldehyde, ketone and contain the product that aminocompound carries out Maillard reaction with amino acid, peptide, polypeptide, protein etc. and have stronger volatility are the important component that constitutes the feature fragrance of Different Kinds of Meat.Take the method for controlled oxidation, promptly control the degree of fats oxidn, can make fully oxidation of fat under the situation of becoming sour not producing, content height, the kind of important aldehyde, ketone carbonyl precursor are many in the oxidation products that obtains.Not only quality is more stable with meat flavour that the further reaction for preparation of this fatty controlled oxidation precursor goes out, and it is strong to have the true property of picture, the advantage that the characteristic fragrance of meat aromatic flavour, harmony and various meat is outstanding, it can be used on as natural level foodstuff additive in multiple food flavouring such as chickens' extract, condiment for instant noodles, sausage, can, quick-freezing boiled dumplings or the food.
Existing method adopts under the heating condition, the airway ventilation prepares precursor of meat-flavour essence (Sun Baoguo in conjunction with mechanical stirring, Xie Jianchun, Liang Menglan, Peng Qiuju, Wen Zhiyong. a kind of fatty controlled oxidation prepares the method .ZL 200410030864.4 of precursor of meat-flavour essence), exist that energy consumption height, reaction vessel are unsuitable for cleaning, loaded down with trivial details defective is amplified in industry.
Summary of the invention
The purpose of this invention is to provide a kind of method that adopts gas lift type common loop reactor to prepare fat to control oxidation product.This method has overcome the shortcoming and defect of existing method.Used gas lift type common loop reactor, in bubbling reactor, added the inner member guide shell, when blasting gas in the guide shell, there is density difference in the inside and outside gas-liquid mixed phase of guide shell, form circulation around guide shell, gas-liquid two-phase is mixed well, thereby increase gas-liquid mass transfer performance and gas-liquid contact area by a larger margin, cut down the consumption of energy.Adopt gas lift type common loop reactor to prepare fat to control oxidation product, have the advantage that energy consumption is low, easy to clean and realization industry is amplified.
Technological process of the present invention is as follows: the fat of the weighing certain mass reactor of packing into, open reactor heating system and water of condensation, and after melting, fat adds the certain mass antioxidant again; Bubbling air produces circulation, utilize circulation with fat and antioxidant uniform mixing, reach preset heating temperature after, control certain air velocity and carry out the oxidizing reaction certain hour, obtain the fats oxidn product, collect and its peroxide value of sampling and measuring, anisidine value, acid number and total carbonyl content.
