Embodiment 1

[0041] The extraction of embodiment 1 capsicum oleoresin

[0042] Weigh 1 ton of fresh green pepper (with a capsaicin content of 0.658%), pulverize it with a pulverizer, and put it into an extraction tank with an auger. Add 50% edible ethanol which is 4 times the weight of pepper, and stir and extract at 80° C. for 3 times, each time for 2 hours. The extract is filtered through two stages, the primary filtration is 200 mesh plate and frame filtration, the secondary filtration is diatomaceous earth filtration, and the fine filtrates are combined. The fine filtrate is ultrafiltered with a 50nm ceramic membrane, and the operating conditions are: operating pressure 0.15Mpa, material temperature 31°C, full cycle. The capsicum extract fine filtrate was concentrated under vacuum conditions of 90°C and 0.09Mpa to recover the solvent, and then desolvated and residually treated for 3 hours under vacuum conditions of 70°C and 0.09Mpa to obtain capsicum oleoresin. After testing, the pur...

Embodiment 2

[0043] Example 2 Extraction of capsicum oleoresin

[0044] Weigh 1 ton of fresh green pepper (with a capsaicin content of 0.632%), pulverize it with a pulverizer, and put it into an extraction tank with an auger. Add 70% edible ethanol which is 4 times the weight of pepper, and stir and extract at 80° C. for 3 times, each time for 2 hours. The extract is filtered through two stages, the primary filtration is 200 mesh plate and frame filtration, the secondary filtration is diatomaceous earth filtration, and the fine filtrates are combined. A 30nm ceramic membrane is used to perform ultrafiltration on the fine filtrate. The operating conditions are: operating pressure 0.20Mpa, material temperature 25°C, full cycle. The capsicum extract fine filtrate is concentrated under the vacuum condition of 100°C and 0.09Mpa to recover the solvent, and the solvent is removed for 3 hours under the vacuum condition of 70°C and 0.09Mpa to obtain capsicum oleoresin. After testing, the purity o...

Embodiment 3

[0045] Example 3 Extraction of capsicum oleoresin

[0046] Weigh 1 ton of fresh green pepper (capsaicin content is 0.667%), pulverize it with a pulverizer, and put it into an extraction tank with an auger. Add 95% edible ethanol which is 4 times the weight of pepper, and stir and extract at 80° C. for 3 times, each time for 2 hours. The extract is filtered through two stages, the primary filtration is 200 mesh plate and frame filtration, the secondary filtration is diatomaceous earth filtration, and the fine filtrates are combined. The fine filtrate is ultrafiltered with a 50nm ceramic membrane, and the operating conditions are: operating pressure 0.15Mpa, material temperature 28°C, full cycle. The capsicum extract fine filtrate is concentrated under the vacuum condition of 96°C and 0.09Mpa to recover the solvent, and is desolvated and residually treated at 70°C and under the vacuum condition of 0.09Mpa for 3 hours to obtain capsicum oleoresin. After testing, the purity of c...

Abstract

The invention relates to the technical field of food, in particular to a method for extracting capsicum oleoresin. The extraction method comprises: extracting capsicum with alcohol and filtering to obtain capsicum alcohol extract; using ceramic membrane ultrafiltration technology to perform ultrafiltration, concentration, and solvent residue removal on capsicum alcohol extract to obtain capsicum oleoresin; the ultrafiltration condition is : The pressure is 0.05 ~ 0.5Mpa, the material temperature is 20 ~ 40 ℃, full cycle. The invention can not only increase the yield of capsicum oleoresin, but also improve the purity of capsicum oleoresin.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a method for extracting capsicum oleoresin. Background technique [0002] Capsicum, scientific name: Capsicum annuum L., Solanaceae, Capsicum genus, is an annual or limited perennial herb. The fruit is usually conical or oblong, green when immature, and bright red, green or purple when ripe, with red being the most common. [0003] Capsicum oleoresin, also known as capsicum extract, capsicum oil, and capsicum essential oil, is obtained by crushing mature fruits of capsicum (Cdpsicumannuum) in the family Solanaceae and extracting them with organic solvents. Therefore, it is also called capsicum extract, capsicum oil, capsicum essential oil. Capsicum oleoresin is a mixture of many substances, mainly composed of capsicum pigments and spicy substances. Its representatives are capsanthin, capsanthin, capsanthin, zeaxanthin, violaxanthin, capsanthin diacetate, capsanthin palmitate, etc...
