Embodiment 1

[0049] 1. Raw material processing: remove impurities, wash and drain fresh and dried wolfberry or seeds, dry them with low-temperature blast for about 25 hours, and make the water content reach about 12%. into the subcritical extraction kettle.

[0050] 2. Subcritical extraction

[0051] Compress the subcritical extractant (butane) into a liquid state at a temperature < 35°C and a pressure of 0.5Mpa, inject it into the extraction kettle, stir and mix with the blank, keep the volume ratio of the extraction solvent to the seed blank greater than 2:1, and control Solvent temperature < 35°C, system pressure 0.6MPa, extraction time 50min, filter to separate the solid and liquid phases, transfer the liquid phase mixed solution into a temporary storage tank, and complete a immersion extraction.

[0052] 3. Analysis

[0053] After soaking and extracting for 3-4 times, the mixed solution in the temporary storage tank is transported into the first-level analysis kettle through the hig...

Embodiment 2

[0063] 1. Raw material processing: remove impurities, wash and drain fresh and dried medlar or seeds, and dry them with low-temperature blast for about 26 hours to make the water content reach about 10%. Critical extraction kettle.

[0064] 2. Subcritical extraction

[0065] Compress the subcritical extractant (acetone) into a liquid state at a temperature <40°C and a pressure of 0.6 MPa, inject it into the extraction kettle, stir and mix with the blank, keep the volume ratio of the extraction solvent to the seed blank greater than 3:1, and control the solvent Temperature <40°C, system pressure 0.6MPa, extraction time 60min, filter to separate the solid and liquid phases, transfer the liquid-phase mixed solution into a temporary storage tank, and complete a immersion extraction.

[0066] 3. Analysis

[0067] After soaking and extracting for many times, the mixed solution in the temporary storage tank is transported and injected into the first-level analytical tank through a ...

Embodiment 3

[0077] 1. Raw material processing: remove impurities, wash and drain fresh and dried medlar or seeds, dry them with low-temperature blast for about 26 hours, and use a water content of about 11%. Critical extraction kettle.

[0078] 2. Subcritical extraction

[0079] Compress the subcritical extractant (ethane) into a liquid state at a temperature < 45°C and a pressure of 0.7mpa, inject it into the extraction kettle, stir and mix with the blank, keep the volume ratio of the extraction solvent to the seed blank greater than 4:1, and control The solvent temperature is <45°C, the system pressure is 0.7MPa, and the extraction time is 70 minutes. The solid and liquid phases are separated by filtration, and the liquid phase mixed solution is transported into a temporary storage tank to complete a soaking extraction.

[0080] 3. Analysis

[0081] After soaking and extracting for many times, the mixed solution in the temporary storage tank is transported through the high-pressure di...

Abstract

The present invention provides a production process of medlar essential oil and edible meal powder. The production process comprises: pressing medlar or seed thereof into a billet, carrying out subcritical extraction, carrying out solid-liquid separation after the extraction to obtain a solid wet meal and a mixed solution, carrying out desorption evaporation on the mixed solution to remove the extractant so as to obtain the crude oil, further carrying out molecular distillation refining on the crude oil to obtain the medlar functional essential oil, completely removing the residual solvent from the solid wet meal, carrying out low-temperature drying, puffing, milling, and powder making, and screening with a 100-180 mesh sieve so as to obtain the medlar edible meal powder. With the method of the present invention, the complex processes that the chemical and physical methods are used to perform deacidification, decolorizing, deodorization and the like in the traditional grease refining are eliminated, the process is short, the efficiency is high, the acid value of the essential oil after the molecule distillation is 0.21-0.23 mg/g, and the essential oil meets the national grade-one edible oil standard. In addition, the oil-extracted meal powder obtained through the method of the present invention still contains all the nutrition and active components and pharmacological functions of the medlar or seeds excluding the oil, and is the high-quality additive for preparing the food or health product.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a processing technology of wolfberry essential oil and edible meal powder. Background technique [0002] Lycium barbarum (Lyciun barbarum L) is the dry and mature fruit of Lycium chinense Mill (Lycium chinense Mill), a traditional Chinese herbal medicine and health food in my country. [0003] The medical records of all dynasties in my country have clearly recorded the pharmacological effects of wolfberry: wolfberry is flat in nature, sweet in taste, enters the two meridians of sweet and sweet, and has the effects of nourishing kidney, nourishing yin and essence, nourishing liver and eyesight, strengthening waist and tendons. [0004] According to the "Pharmacopoeia of the People's Republic of China", wolfberry can nourish the liver and kidney, benefit the essence, and is used to treat dizziness, dizziness, tinnitus, soreness of the waist and knees, and diabetes. L...
