Production technique for extracting pepper essence by supercritical carbon dioxide process

Abstract

The invention provides the production technique for extracting pepper essence by supercritical carbon dioxide process which consists of, loading the dried pricklyash peel into air tight comminuting machine for disintegration, loading into abstraction bucket for abstraction with carbon dioxide liquid, lifting the abstraction pressure to 15-35 MPa, flowing the carbon dioxide liquid into the segregation still, thus disintegrating refined pricklyash peel with carbon dioxide.

Description

technical field [0001] The invention relates to a production process of condiments, in particular to a production process for extracting prickly ash essence by supercritical carbon dioxide method Background technique [0002] Pepper (Zanthoxylum L.) belongs to Rutaceae, and its peel is known as one of the "eight condiments", and is a commonly used cooking seasoning and traditional Chinese medicine ingredient in the family. Zanthoxylum bungeanum has a long history of cultivation in my country and is widely planted. Zanthoxylum bungeanum is an important spice and medicinal economic crop. In the process of implementing the agricultural industrial structure adjustment and returning farmland to forest policy in my country, its planting area and output have increased rapidly. By 2001, the national Zanthoxylum bungeanum planting area had exceeded 60,000 Hectares, the output of pepper peels is nearly 100,000 tons, and it has formed nationally famous pepper planting bases such as Han...

Problems solved by technology

However, the domestic production technology of Zanthoxylum bungeanum is extracted with organic solvents, the product yield is low, the loss of volatile oil is large, and there are solvent residues, and the food safety is poor. At the same time, most organic solvents are volatile, flammable and explosive.
