Abstract

The invention discloses ultrasonic treatment cold pressed sesame oil and a preparation method thereof. The ultrasonic treatment cold pressed sesame oil is prepared from the following raw materials: white sesame seed, baking soda, aloe, wolfberry, mint, red date, codonopsis pilosula, dandelion, white spirit, citric acid, cane sugar, vitamin C, almond powder and a proper amount of water. As a certain amount of Chinese herbal medicines are added, a decoction obtained after the Chinese herbal medicines are decocted contains various active ingredients which are essential to human body and have important effects of removing free radicals in human body, delaying senescence, resisting oxidation and maintaining dynamic equilibrium of human body. Under vibratory action of ultrasonic power, the active ingredients are easy to combine with sesame kernel tissues and infiltrate into protein inside the sesame kernel. Permeating function is accelerated. Finally, the active ingredients undergo hydraulic pressing along with the sesame kernels and enter sesame oil. By an advanced technology for pressing, oil yield is high, nutrient content is high, and waste is avoided.

Description

A kind of ultrasonic Treatment coldly-squeezed sesame oil and preparation method thereof

Technical field

The invention belongs to the Technology field of food, be specifically related to a kind of ultrasonic Treatment coldly-squeezed sesame oil and preparation method thereof.

Background technology

Semen Sesami does not contain only abundant oils and fats and protein, also has well health care and medical value.In recent years, the consumption figure of China's Semen Sesami and Semen Sesami converted products increases year by year, and within 2009, Chinese Semen Sesami net importation amount is more than 270,000 tons.Traditional sesame oil making technique is first to roast Semen Sesami high temperature, uses water substitution or milling process to produce Oleum Sesami the most again.High temperature roasts and makes Oleum sesami produce strong fragrance, but Oleum sesami color and luster is very deep, poor transparency, simultaneously sesame protein serious degenerative and destruction, causes sesame-send cake, slag only as cheap feed applications, causes the waste of sesame protein resource.

Semen Sesami low-temperature cold pressing technique can retain the bioactive substance in Semen Sesami to greatest extent, and obtaining delicate fragrance, color is shallow, while high-quality that transparency is good (edible, medicinal, keep healthy, massage) Oleum sesami, obtain the sesame-send cake that protein denaturation degree is the lowest.The size-reduced edible sesame protein powder that can obtain high-quality of cold pressing sesame-send cake, or the edible sesame protein of the more high protein content such as further processed production Semen Sesami protein concentrate, Semen Sesami separation albumen.

K.Ohsaka research finds that the pressure wave kinetic energy of ultrasonic generation lures that water nucleation freezes into, and the cavitation bubble of the ultrasonic generation of 21kHz can make the degree of supercooling as little as 5 DEG C of water.The result of study of Hoztlmi etc. is pointed out, the ultrasonic wave energy of suitable parameter (45kHz.0.28W/cm2) reduces the degree of supercooling of pure water crystallization, promotes that ice crystal is formed.Rachel Chow etc. have studied the ultrasound wave impact on aqueous sucrose solution degree of supercooling, finds that ultrasound wave greatly reduces the degree of supercooling of aqueous sucrose solution.From these results of study, the ultrasonic degree of supercooling on water or aqueous solution affects rule and is not quite similar, and the water dissolution in food has multiple different organic and inorganic compound.

Summary of the invention

The present invention is in order to improve the shortcoming that tradition Semen Sesami oil expression color is deep, poor transparency, sesame protein destruction is serious, a kind of method inventing low-temperature cold pressing, utilize low temperature to make the Free water in Semen Sesami form ice crystal simultaneously, oil-water separation in advance, improve oil expression rate and product oil purity with this, realize particular by following method:

A kind of ultrasonic Treatment coldly-squeezed sesame oil, it is characterized in that, be made up of the raw material of following weight portion: Semen sesami Albae 3000 ~ 3500, sodium bicarbonate 120 ~ 140, Aloe 3 ~ 6, Fructus Lycii 10 ~ 15, Herba Menthae 2 ~ 3, Fructus Jujubae 40 ~ 50, Radix Codonopsis 20 ~ 30, Herba Taraxaci 4 ~ 7, Chinese liquor 200 ~ 250, citric acid 0.5 ~ 1, sucrose 20 ~ 35, vitamin C 0.2 ~ 0.4, Semen Armeniacae Amarum powder 10 ~ 15 and appropriate water.

The preparation of a kind of ultrasonic Treatment coldly-squeezed sesame oil is taken precautions against, it is characterised in that include following step:

(1) blending sodium bicarbonate, Aloe, Fructus Lycii and other following residual components being not directed to, put in marmite, add the water of 25 ~ 30 times of its weight portions, and decoction boils 80 ~ 100min and becomes original 1/3 to decoction, filters out decoction and be incubated at 75 ~ 85 DEG C standby；

(2) getting out Semen sesami Albae, join in the decoction described in (1), be watered to material-water ratio is 1:3 simultaneously, puts in ultrasonic processor, and under the conditions of being incubated 75 ~ 85 DEG C, ultrasonic power 260 ~ 300W effect 20 ~ 25min makes the abundant imbibition of Semen Sesami, leaches Semen sesami Albae；

(3) the Semen sesami Albae clear water that (2) obtain is eluriated 4 ~ 6 times repeatedly to Semen Sesami skin of decorporating, the Semen Sesami Nigrum core obtained first is led to hot blast and air-dries 10 ~ 15min to dry tack free, put into the refrigerating chamber freezing 3 ~ 5h of-20 ~-15 DEG C, placing into lyophilizing in vacuum freeze-drying machine directly to volatilize ice crystal water, controlling moisture is 5 ~ 8%；

(4) the every 2Kg of Semen Sesami Nigrum core described in (3) is once put in hydraulic oil press, control temperature 30 ~ 40 DEG C, press chamber pressure gradually rises to 50MPa, pressure release after squeezing 20 ~ 25min, take out the sesame-send cake in press chamber, repeat squeezing 3 ~ 5 times after the most loose, finally from fuel-displaced seam, collect out Oleum sesami.

nullOwing to Semen Sesami contains substantial amounts of oils and fats and protein，So profit abstracts oil from sesame，The oils and fats form that is primarily present in Semen Sesami Nigrum core is in the cell that there is trophocyte，Plant cell has cell wall and cell membrane to intercept as shielding，Tradition is to utilize this tissue of high temperature，Or direct voltage racks cell wall，The high still protein degeneration the most of former oil yield，Nutritive value is the highest，The latter's oil yield is slightly lower，Retain suitable protein component，But it is serious to can't do without waste，Invention is found by research: utilize different the ultrasonic of electrical power to process Semen Sesami soluble component，Find that ultrasonic electric power can be gradually reduced the degree of supercooling of water suction Semen Sesami Nigrum core soluble component，Greatly reduce refrigeration requirement，It is probably the pressure wave that ultrasonic cavitation causes to induce Semen Sesami soluble component and form the water in solution，The combination water liberated in Semen Sesami Nigrum core becomes Free water，The nucleation accelerating water freezes.

After having liberated the combination water in Semen Sesami Nigrum core, significantly liberate the oils and fats in structure, moreover, after Semen Sesami Nigrum core K cryogenic treatment water suction after supersound process, then K cryogenic treatment, the ice crystal of formation has reason to rack cell wall, the productive target materials such as release oils and fats, last vacuum heats up and makes water of crystallization directly volatilize, and is easier to Oleum sesami the purest, efficient during squeezing, and the content of protein is the abundantest.

Beneficial effects of the present invention: invention adds a certain amount of Chinese herbal medicine part, decoction after Chinese herbal medicine decocting contains the active component of various needed by human body, can remove human free radical, slow down aging, antioxidation, maintenance human body dynamic equilibrium all have important effect, under the effect of vibration of ultrasonic power, it is easy to combine with Semen Sesami Nigrum core tissue, penetrate into the protein component within Semen Sesami Nigrum core up, accelerate infiltration function, last squeezes with hydraulic pressure, entering Oleum sesami, sophistication squeezes, and oil yield is high, nutritional labeling is high, it is to avoid waste.
