Abstract

The invention provides a preparation method of a saffron crocus extract, wherein the preparation method comprises the following steps: S1, adding saffron crocus to an extracting solvent, extracting atroom temperature, and then separating to obtain an extracted solution and a residue; S2, concentrating the extracted solution at the temperature of 70-80 DEG C, and separating to obtain a concentrated solution and a volatile solvent; and S3, carrying out room temperature extraction and concentration of the volatile solvent and the residue in a circulating operation, merging the concentrated solutions obtained in all the operations and the concentrated solution obtained in the step S2, making the volume constant until the concentration ratio of saffron crocus to the extract is 1:24, and thus obtaining the saffron crocus extract. The preparation method can be used for industrialized processing, ensures that the addition amount of the saffron crocus is quantified in the premise without introducing other solvents in each bottle of Baijiu; the product has the advantages of uniform color, pleasant taste, suitable aroma and good taste, and old Baijiu cannot change with prolongation of the storage time, the quality of Baijiu is stable, and the storage time of Baijiu is prolonged.

Description

Technical field [0001] The invention relates to a preparation method of saffron extract and old liquor containing the saffron extract, belonging to the technical field of food engineering. Background technique [0002] Chongming old liquor is one of the traditional specialty products of Chongming Island. As early as more than a hundred years ago, Chongming Lao Liquor was well-known in the Shanghai and Jiangsu region. It uses glutinous rice as raw material and is carefully brewed by mixing medicine and water after drenching rice. In addition, the wine is sweet and creamy in color, so it is also called "sweet white wine", "rice wine" and "water wine". Chongming old liquor has authentic quality and unique flavor, which is different from ordinary liquor and yellow wine. The wine is sweet and slightly sour, with a mellow aroma, moderate alcohol content (12°-13°), strong stamina and aftertaste. It is a popular low-alcohol wine, especially "Cauliflower Yellow" and "October White" "Th...
