Problems solved by technology

It is known that the existing processing methods for preparing high-content O-acetyl products usually use solvent extraction, microwave extraction, ultrasonic-assisted extraction, etc. These methods may take a long time to easily oxidize O-acetyl groups, or deactivate them after heating , or for auxiliary extraction, are not very satisfactory

Abstract

The invention discloses a method for processing a high-O-acetyl-content raw aloe product. The method comprises the following steps of: washing and peeling the fresh aloe leaves in limited time, or using the whole fresh aloe leaves; adding pectinase to perform enzymolysis; crushing, grinding and centrifugally separating to obtain pulpy aloe juice; discoloring and filtering through activated carbon, and filtering through kieselguhr to obtain clean aloe juice; concentrating through a reverse osmosis membrane and a negative-pressure normal-temperature falling membrane / film to prepare concentrate of aloe gel; and freezing and drying to obtain dried aloe powder having high O-acetyl content. The preparation method provided by the invention has the advantages that the whole process is performed at normal temperature; no thermal / chemical / biological variation appears; the processing is carried out in a closed way; the isolation of active substance not occurs; and original effects and active components are retained effectively. The prepared dried aloe powder is high in O-acetyl content. The O-acetyl contents of the peeled dried aloe powder and full-leaf dried aloe powder are both high and respectively can reach 122,400mg / kg and 165,300mg / kg to the maximum, which are far more than the value specified by the industrial standard. The method is applicable to various types of dried raw aloe powder.

Description

technical field [0001] The invention relates to the technical field of aloe processing, in particular to a processing method of a high-content O-acetyl raw material aloe product. Background technique [0002] Aloe is a perennial evergreen succulent herb belonging to the Liliaceae family, belonging to tropical plants. Aloe is an ancient medicinal plant. The ancient Chinese medical books "Shen Nong's Materia Medica" and "Compendium of Materia Medica" all record the special medicinal effects of aloe. Aloe vera has been used as folk medicine for more than 4,000 years. It has been known as "plant doctor", "universal medicine" and "natural beautician" since ancient times. Because of its anti-inflammatory, bactericidal, wound-healing, anti-diabetic, anti-oxidative and anti-cancer effects, it has aroused great interest of scientists. In recent years, aloe vera has been widely used in cosmetics, food, health products and other fields, and its development prospects are very promisin...
