Problems solved by technology

However, the cost of such capsaicin crystals is 4-5 times higher due to repeated production links, and at the same time destroys and decomposes part of capsaicin and dihydrocapsaicin components, so that the yield is only between 60%-70%. Product yield is very difficult

Embodiment 1

[0006] Embodiment 1: A kind of new technique of capsaicin crystal substance extraction, chooses capsicum japonica as raw material, puts into raw material 7200kg in extractor, uses 76% edible ethanol, rinses repeatedly for 3 hours, and extract is filtered through 500 mesh filter screen , and then use an ethanol distillation tower to distill out ethanol to produce 90kg of oleoresin with a capsaicin content of 11.5%. First, through molecular distillation, at 210 degrees Celsius and a negative pressure of 30 Pa, distill the oil-soluble colorless pepper with a capsaicin content of 11.5% Refining 36kg, then adding 2.52kg of potassium hydroxide into the reaction kettle, saponifying at 40 degrees Celsius for 120 minutes, then adding 324kg of water, and settling in a cool shade for 2 days, filtering the water with a 500-mesh filter and drying to obtain a capsaicin content of 80 % crystal capsaicin 4.65kg, a total yield of 89%; then through molecular distillation, at 240 degrees Celsius,...

Embodiment 2

[0007] Embodiment 2: A new process for extracting capsaicin crystals, choose Tianying pepper as raw material, put 9000kg of raw material into the extractor, use 76% edible ethanol, rinse repeatedly for 3 hours, and the extract passes through a 500-mesh filter screen Filter, then use the ethanol distillation tower to distill out ethanol to produce 84kg of oleoresin with a capsaicin content of 12.6%, first go through molecular distillation, and distill out a colorless oily resin with a capsaicin content of 13.1% at 210 degrees Celsius and a negative pressure of 30 Pa. Capsicum extract 31kg, then add potassium hydroxide 2.17kg in the reaction kettle, saponify at 40 degrees Celsius for 120 minutes, then add 279kg of water, cool and shade for 2 days, filter the water with a 500-mesh filter and dry to obtain the capsaicin content 76% crystal capsaicin 4.6kg, total yield 86%; then through molecular distillation, at 240 degrees Celsius, under a negative pressure of 45 Pa, distill out 4...

Abstract

The invention discloses a new process for extracting capsaicin crystal substances, belonging to the technical field of chilli deep processing. The new process is characterized by processing capsicum oleoresin with molecular distillation equipment to distil off oil soluble colorless capsicum oleoresin without capsanthin at 210 DEG C and under the negative pressure of 30Pa, saponifying the oil soluble colorless capsicum oleoresin in a reaction kettle at 40 DEG C for 120 minutes by using a 7% potassium hydroxide solution, then adding water with volume being nine times that of the saponified product, standing in the shade place to generate crystals, filtering the crystals out of water with a 500-mesh filter screen and directly drying the crystals, thus obtaining the capsaicin crystal products. The new process has the following beneficial effects that: various active ingredients are completely reserved and the active ingredients of capsaicin are not destroyed and decomposed, thus the product yield is greatly increased; and the new process is suitable to popularize and apply in chilli deep processing.

Description

technical field [0001] The invention belongs to the field of deep processing of capsicum, in particular to a process for extracting capsicum essence and capsaicin. Background technique [0002] After nearly 10 years of development, capsaicin has made great progress both in terms of output and product content. However, the production process is still stuck in the use of solvent precipitation extraction. The process of solvent extraction is as follows: grind peppers to make 1cm long and 3mm diameter granules, extract 100kg of granules and 500kg of No. 6 solvent in a horizontal rotary extractor for 3 hours, then pass through a 100-mesh filter, filter and precipitate for 1-3 hours , and then according to the flow rate of 1700-2200ml / min, the first distillation is carried out at 50 degrees Celsius, and the extract is then subjected to the second and third distillations at 50 degrees Celsius, and then mixed with 75% ethanol 1:4 to remove the spicy four The second time, the despi...
