Embodiment Construction

[0014] γ-Lauryl lactone, also known as 3-dodecalactone, γ-dodecalactone, is a five-membered ring lactone compound. γ-Lauryl lactone is an important class of spices. It is a colorless and clear liquid with oil Powder aroma, peach flavor, long-lasting aroma, its molecular formula is C12H22O2, the structural formula is as follows figure 1 shown. It has a low aroma threshold and is widely found in peaches, apricots, osmanthus, soybean hydrolyzed protein, butter, egg fruit flowers, etc. In osmanthus, jasmine, gardenia, lily of the valley, orange blossom, white rose, lilac, acacia It is often used in other daily spices, and it is also a good raw material for preparing food flavors such as peaches, melons, plums, apricots, cherries, and osmanthus. γ-lactone fragrances are insoluble in water, but soluble in organic solvents such as ethanol. The method for producing natural fragrance gamma-laurolactone by using microbial conversion method is prepared according to the following steps:...

Abstract

The invention discloses a method for producing natural perfume gamma-dodecalactone by microbial conversion, which comprises the following production steps: primary screening, secondary screening, primary fermenting and secondary fermenting. The purity of the produced natural perfume gamma-dodecalactone can be up to 97.9%. The method has the advantages of moderate reaction condition, simple operation, high selectivity, low production cost, low price and easy acquisition of raw materials, natural resource conservation and environmental friendliness, and is beneficial to ecological equilibrium. The production method can be widely used in lactone perfume production.

Description

technical field [0001] The invention belongs to the field of biomedicine and light industry, and in particular relates to a method for producing natural fragrance γ-laurolactone by using a microbial transformation method. Background technique [0002] Currently, most of the fragrance compounds on the market are produced through chemical synthesis or extraction from plants. Animals and plants are an important source for the production of natural flavors. However, due to limitations in raw materials and technology, the output is relatively low. The preparation methods of traditional natural spices mainly include steam distillation, solvent extraction, pressing and grinding, adsorption and so on. These methods can extract effective aromatic components in natural substances. However, because this production method is a resource-based industry, many factors such as climate conditions, geographical location, natural disasters, variety variation, political environment, and relat...
