Abstract

The present invention relates to a kind of preparation methods of sesame oil, particularly a kind of to utilize conventional supercritical CO₂Extraction equipment extracts the technical process of effumability sesame flavor oil from natural sesame seed seed, first natural sesame seed seed is cleaned, it removes sand and dust sundries and surface impurity obtains pure sesame seed, baking sesame seed damage or mechanism are crushed to semi-laminar black sesame powder again, black sesame powder is then placed in supercritical CO₂In extraction kettle, its pressure, temperature, CO are controlled₂Separating and extracting under flow and time conditions, while point two-stage collects a kettle and collects two-stage respectively and contains different components and volatile extract under different pressures and temperature condition, by two-stage collect gained extract mix just finished product sesame flavor oil.This method is simple for process, and securely and reliably, yield is high, and quality is good, does not destroy the edibility of sesame grease.

Description

A kind of preparation method of sesame oil

Technical field：

The invention belongs to food processing technology field, it using natural sesame seed seed is raw material through supercritical extract system to be related to a kind of The standby extraction and separation process process into the natural perfume essential oil for seasoned food field, particularly a kind of preparation side of Oleum Sesami Method.

Technical background：

Sesame is a kind of natural edible oil materials product.Oil-containing composition nutritive value in sesame is high, common to contain For oil mass between 30%~50%, sesame oil is usually commonly referred to as sesame oil by people.This is primarily due to the perfume (or spice) contained in sesame oil Monosodium glutamate is higher.People mainly adjust the fragrant degree of food and mouthfeel in edible sesame oil using fragrance therein.At present, When we are by the use of sesame oil as flavouring, generally (also there is referred to as essence by essence contained in sesame or for sesame oil essence Oil) and contained grease mix and extracted from sesame seed by squeezing, and really serve the essential oil of seasoning into Part contained ratio in this compound lard is not high, so realizing that fragrance adjusts by using sesame oil in some cases When, toward contact there is inconvenient for use, essence dosage it is not easy to control the shortcomings of, and due to essence be included in sesame oil it In, using being just not easy to realize application purpose under water-soluble occasion.At present, have extremely suitable natural using preparing for steam distillation Sesame essence or essential oil process, but such method is low there is recovery rate, complex process, and the low grade of product purity lacks Point.

Invention content：

It is an object of the invention to overcome in the existing seed from natural sesame seed to extract in the sesame oil technique containing essential oil There are the shortcomings that, seek to design it is a kind of it is direct using supercritical technology from sesame separation and Extraction sesame oil method.

To achieve these goals, the present invention is using natural pure sesame seed as raw material, through over cleaning, baking, crush, Extract (supercritical CO₂), the technical process such as mixed collection produce sesame flavor oil, first natural sesame seed seed is cleaned, is removed husky Trifle in the world object and surface impurity obtain pure sesame seed, then sesame seed carries out to baking is subsequently broken up or mechanism is crushed to semi-laminar Then black sesame powder is placed in supercritical CO by black sesame powder₂In extraction kettle, its pressure, temperature, CO are controlled₂Under the conditions of accumulative circular flow Extraction, while point two-stage collects a kettle and collects two-stage respectively and contains different components and volatile under different pressures and temperature condition Extract, the extract mixing that two-stage is collected to gained just obtain finished product sesame flavor oil.

During present invention process baking box controlled at 250~350 DEG C, baking time is 30~50 minutes, CO₂ Accumulative circular flow is 0.040~0.045 liter/gram black sesame powder, and extraction kettle pressure is 15~25MPa, and temperature is 40~80 DEG C；It receives The pressure for collecting kettle I is 7~8MPa, and temperature is 20~40 DEG C；The pressure for collecting kettle II is 5~6MPa, and temperature is 20~40 DEG C.

The sesame flavor oil of effumability is produced from sesame seed using this technical process, yield is 1~3%, wherein Volatilizable composition accounts for 0.5~1.5%, and product is compared compared with the sesame oil that press type is produced has volatility high, and quality is good, fragrance The advantages that pure strong, and manufacture craft is simple and easy to control, purity is high, does not destroy the edible of other lubricant components in sesame seed Property.This product can be widely used for food flavor adjusting, have the characteristics of easy to use, thick flavor alcohol.

Specific embodiment：

The implementation of the present invention can be carried out according to following Examples：

Embodiment 1：

7000 grams of natural high-quality sesame seeds are taken, are rinsed three times with clear water, and are toasted after removing graininess sand and dust common 300 DEG C of temperature control toasts 40 minutes in case, and the sesame after baking then is broken into semi-laminar or three/a piece of using crusher Shape black sesame powder；Black sesame powder is uniformly placed into 24 liters of extraction kettles of supercritical extraction unit and (two level is equipped in device and collects kettle), It is 18MPa to control extraction kettle pressure, and temperature is 50 DEG C, and the pressure for collecting kettle I is 8MPa, and temperature is 30 DEG C, collects the pressure of kettle II Power is 6MPa, and temperature is 25 DEG C, and routine operation is extracted and collected, and works as CO₂When accumulative circular flow reaches 294 liters, stop The extract that two-stage is collected in kettle is collected and mixes to obtain 133 grams of sesame flavor oil products, meets national regulation after testing by extraction Standard.

Embodiment 2：

Take 1500 grams of natural sesame seeds, 300 DEG C of temperature toast 40 minutes after clear water rinses three times, after crushed into semi-laminar or / 3rd sheets are placed into 5 liters of extraction kettles of supercritical extraction unit, control extraction kettle pressure as 22MPa, temperature 70 DEG C, the pressure for collecting kettle I is 7.5MPa, and temperature is 35 DEG C, and the pressure for collecting kettle II is 5.8MPa, and temperature is 28 DEG C, is extracted It takes and collects, work as CO₂When accumulative circular flow is 65 liters, stop extraction, merge the gleanings collected kettle I and collect kettle II, obtain 32 grams of sesame flavor oil products, comply with standard after testing.

Claims

1. a kind of preparation method of sesame oil, it is characterised in that in conventional supercritical CO₂It is carried out in extraction equipment, it is characterised in that First natural sesame seed seed is cleaned, sand and dust sundries is removed and surface impurity obtains pure sesame seed, then sesame seed is dried Roasting broken or mechanism is crushed to semi-laminar black sesame powder, and black sesame powder then is placed in supercritical CO₂In extraction kettle, control its pressure, Temperature, CO₂Accumulative circular flow is extracted, while two-stage is divided to collect kettle under different pressures and temperature condition and is collected two respectively Grade containing different components and volatile extract, by two-stage collect gained extract mix just finished product sesame flavor oil.
