Problems solved by technology

[0004] At present, only rose essential oil is the only research product in the deep processing of roses, and the production of rose essential oil mainly adopts steam distillation method, which has high extraction temperature and long time, and the distilled essential oil has darker color, bad aroma and lower oil yield. Low
At the same time, long-term high-temperature distillation degrades active substances in roses such as pigments and flavonoids, resulting in waste of resources and reducing the added value of roses

Abstract

The invention belongs to the technical field of an agricultural product deep processing method, and particularly relates to a comprehensive utilization method of roses. The four products including rose essential oil, rose absolute oil, rose concentrated solution and rose pollen are finally obtained by the method. The method comprises the following concrete steps that (1) fresh roses or frozen flowers are introduced into subcritical fluid for extraction according to a certain mass ratio to obtain extraction liquid 1 and rose slag I; the extraction liquid 1 is subjected to pressure reduction and temperature rise to obtain rose extrac; after molecular distillation, separation and purification, the rose essential oil and the rose absolute oil are obtained; (2) deionized water or a citric acid water solution is added into the rose slag I; after the processes of crushing pulping, enzyme deactivation, cooling, filtering, centrifugation and the like, rose juice or rose slag III is obtained; the rose juice is concentrated to obtain a rose concentrated solution; (3) the rose concentrated solution added with or without the rose absolute oil, and microcapsule wall materials are uniformly mixed, and are then subjected to high-speed shearing, high-pressure homogenizing and spraying drying to obtain the rose pollen.

Description

technical field [0001] The invention belongs to the technical field of deep processing methods of agricultural and sideline products, and in particular relates to a comprehensive utilization method of roses. Background technique [0002] Rose (Rosarugosathunb.) is an upright and deciduous shrub of Rosaceae (Rosaceae). It has bright colors, pleasant fragrance and high oil content. It is an important special economic plant in my country. An important raw material for the food industry, spice industry, etc. The medicinal use of roses has a history of more than two thousand years in my country. "Materia Medica Justice" records: "The fragrance of roses is the strongest, clear but not turbid, harmonious but not fierce, softening the liver and refreshing the stomach, promoting qi and blood, and there are almost no other fragrances." Modern pharmacological analysis shows that roses contain phenols, phenylethyl alcohol, nerol, organic acids, red pigments, yellow pigments, waxes, and...
