Process for abstracting both paprika oleoresin and paprika capsicum from pimiento

Abstract

The invention relates to a process for getting both paprika and capsicum oleoresin by extracting through an extracting solvent taking red chilli as raw material, which comprises the following procedures: 1. processing dry red chilli, separating the skins from the seeds, pulverizing the chilli skins into powder, which will be taken as raw material; 2. adding the extracting solvent in proportion 1:2-8 to the raw material in an extractor, extracting 2-6 hours under temperature 20-60 DEG C, and then filtering; the filtered out residuals will become chilli residues after removing solvent and will be taken as a by product; 3. concentrating above filter liquid into a capsicum oleoresin; the solvent can be recycled for circulating; 4. separating the capsicum oleoresin to get paprika and capsaicine, removing the solvent respectively to get the paprika and capsicum oleoresin; 5. packing. With the invention, both paprika and capsicum oleoresin can be obtained with one extracting, the comprehensive utilization of the chilli is improved, so the efficient and hi-scale production of paprika and capsicum oleoresin becomes a possibility.

Description

(1) Technical field [0001] The invention relates to a process for extracting capsicum red and capsicum essence by using red capsicum as raw material and extracting with an extraction solvent. (two), background technology [0002] Capsanthin is a safe and nutritious natural pigment. Its red components are mainly capsanthin and capsanthin. It has bright color, strong tinting power, good thermal stability and high safety. It is an ideal It has nutritional and health effects, and has been proved by modern science to have an anti-cancer function, and has become a recognized functional natural pigment. Capsicum extract is an oily liquid with a strong spicy taste extracted and concentrated from peppers. It is an excellent spicy taste regulator, easy to use and excellent in performance. It is also the main raw material for the production of capsaicin. Biological raw materials are widely used in the pharmaceutical industry, military, pesticides, environmental protection paint, perso...

Problems solved by technology

However, due to the different polarities of capsanthin and capsaicin, it is difficult to obtain both in the current industrial production methods. Most manufacturers of capsanthin now use n-hexane or 6# extraction solvent oil for extraction. Solvent, this method can still extract capsanthin, which can reach more than 95%, but the extraction rate of capsaicin is very low, generally only about 30%, and most of the capsaicin is trapped in the capsicum residue, which is not fully utilized Some manufacturers adopt 95% ethanol as extraction solvent, and the yield of capsaicin is improved, but the yield of capsanthin is very low; in order to improve both yields, some manufacturers first extract capsanthin with 6# extraction solvent oil , and then use ethanol to extract capsaicin, and the two extractions make the production process very complicated and the cost increases, which cannot meet the simple and efficient production requirements
