Problems solved by technology

[0003] The most important method for the industrial production of capsaicin is solvent extraction, which has a high extraction rate and is suitable for large-scale production and application. However, the capsicum oleoresin extracted by conventional solvents needs to undergo refining processes such as degumming before the product can be prepared. Therefore, the production process increase, which also increases the production cost of the enterprise
[0004] At present, there is no report on the research of extracting capsicum oleoresin by using three-phase separation technology

Embodiment 1

[0025] Weigh 100kg of dried chili powder, add 800kg of water, mix the dried chili powder with water evenly, and make chili powder slurry. Add 100kg of ammonium sulfate, stir to dissolve completely, add 900kg of tert-butanol, heat to 40°C, and stir for 6h. After standing still for 1 h, a three-phase system was formed, the upper layer was an organic solvent phase of tert-butanol, the middle layer was paprika and egg white, and the lower layer was ammonium sulfate aqueous solution. Separation was carried out with a centrifuge, the centrifugation speed was 4000r / min, and the centrifugation time was 7min. Collect the obtained tert-butanol organic solvent phase and evaporate under reduced pressure, the condition is 45 ℃, below -0.08MPa, after removing tert-butanol, 27kg of capsicum oleoresin is obtained, and the recovered tert-butanol can be recycled.

Embodiment 2

[0027] Weigh 500kg of dried chili powder, add 5000kg of water, mix the dried chili powder with water evenly, and make chili powder slurry. Add 600kg of ammonium sulfate, stir to dissolve completely, add 6000kg of tert-butanol, heat to 45°C, and stir for 8h. After standing still for 1 h, a three-phase system was formed, the upper layer was an organic solvent phase of tert-butanol, the middle layer was paprika and egg white, and the lower layer was ammonium sulfate aqueous solution. Separation was carried out with a centrifuge, the centrifugation speed was 4000r / min, and the centrifugation time was 8min. Collect the obtained tert-butanol organic solvent phase and evaporate under reduced pressure, the condition is 45 ℃, below -0.08MPa, after removing tert-butanol, obtain capsicum oleoresin 145kg, the reclaimed tert-butanol can be recycled.

Embodiment 3

[0029] Take by weighing 1000kg of dried chili powder, add 7000kg of water, mix the chili powder with water evenly, and make chili powder slurry. Add 900kg of ammonium sulfate, stir to dissolve completely, add 8000kg of tert-butanol, heat to 48°C, and stir for 8h. After standing still for 1 h, a three-phase system was formed, the upper layer was the tert-butanol organic solvent phase, the middle layer was the paprika and protein layer, and the lower layer was the ammonium sulfate aqueous solution. Separation was carried out with a centrifuge, the centrifugation speed was 4500r / min, and the centrifugation time was 10min. Collect the obtained tert-butanol organic phase and evaporate under reduced pressure under the conditions of 50° C. and below −0.08 MPa. After removing tert-butanol, 295 kg of capsicum oleoresin is obtained, and the recovered tert-butanol can be recycled.

Abstract

The invention provides a method for extracting capsicum oleoresin by using a three-phase separation technology, which comprises the following steps of: adding a proper amount of water into dry chili powder, and mixing well to obtain chili powder slurry; adding a certain amount of ammonium sulfate, stirring until the ammonium sulfate is completely dissolved, adding a certain amount of tert-butyl alcohol, heating at low temperature, stirring for a period of time, and standing to form a three-phase system; separating an organic solvent phase by using a centrifugal machine; and removing the tert-butyl alcohol through reduced pressure evaporation to obtain capsicum oleoresin. The three-phase separation technology is utilized, complex equipment is not needed, time and labor are saved, and the method is green and environment-friendly. The method is simple and rapid, tert-butyl alcohol can be recycled and reused by adopting a rotary evaporation method, and cost reduction is facilitated.

Description

technical field [0001] The invention relates to the technical field of food additives, in particular to a method for extracting capsicum oleoresin by using a three-phase separation technology. Background technique [0002] Established in 1982, the three-phase separation technology is a new method for extracting biologically active substances. It was mainly used for the separation, concentration and purification of proteins before. In recent years, it has also been used for the separation and extraction of oils and pigments. Add salt and organic solvent to the crude sample aqueous solution, and after a certain period of time, three phases can be formed. The upper phase is an organic phase, including oil-soluble substances such as oils and pigments; the lower phase is an aqueous phase, including water-soluble substances such as sugars; and The protein precipitates between the organic phase and the aqueous phase to form a third phase, thereby realizing the separation and purifi...
