Abstract

The invention belongs to a kind of edible peanut oil and preparation technology thereof, it is characterized in that the Semen arachidis hypogaeae that shelling is cleaned makes the steaming base of moisture 14-16% respectively, removes the stir-fry base of scarlet and give birth to and to roll thin stock, then by steaming base 40-50%, fry base 20-30%, the mixed squeezing of green compact 20-30, clear oil, cooling, filter pressing get peanut oil with pure fragrance, this peanut oil with pure fragrance has the pure fragrance of ripe peanut, can directly make flavouring oil.

Description

Peanut oil with pure fragrance and preparation technology thereof

The present invention relates to a kind of edible oil and preparation method thereof.

Peanut oil is a kind of edible oil commonly used, and existing production method has milling process and lixiviation process.Lixiviation process is to utilize solvent that the oil in the peanut is extracted, the squeezing rule be adopt peel off, broken, steam the phosphorus matter that stir-fry, strip plate, squeezing, clear oil, press filtration, rehydration remove in the crude oil and make edible peanut oil.The peanut oil that above-mentioned two kinds of methods are produced has all lost the distinctive fragrance of peanut, can only use and can not make flavouring oil as Oleum Sesami as frying in shallow oil, fry, explode with oil, has reduced the use value and the economic benefit of peanut oil.

The purpose of this invention is to provide a kind of peanut oil with pure fragrance and preparation technology thereof who keeps the peculiar fragrance of ripe peanut.

For reaching this purpose, the present invention has taked following preparation technology: 1, slough Pericarppium arachidis hypogaeae, select cleaning, full Semen arachidis hypogaeae; 2, Semen arachidis hypogaeae is made blank with three kinds of methods: a, steam base: Semen arachidis hypogaeae is broken into the 4-8 lobe, rerolls into thin stock, then with the moistening blank of water of the caustic soda that contains 0.05-0.2% salt and Bo Meishi concentration 1 degree to moisture 14-16%, steam base down at 90-100 ℃ at last; B, stir-fry base: in frying pan,, inhale simultaneously and remove scarlet to roll into thin stock after the 100-120 ℃ of parch Semen arachidis hypogaeae; C, green compact: raw peanut kernel is rolled into thin stock.3, squeezing.The thin stock that three kinds of methods are made is fried the ratio mixed back squeezing of base 20-30% and green compact 20-30% to steam base 40-50%, goes into to roll temperature 95-100 ℃, goes into to press moisture content and is controlled at 40%.4, with the expressed breaking of oil, cooling back press filtration obtains peanut oil with pure fragrance.

The peanut oil with pure fragrance that makes with technology of the present invention has the pure fragrance of ripe peanut, and quality reaches one-level peanut oil standard, and the oil yield height, and use value and economic benefit obviously improve.In addition, this technology goes into to press the moisture content height because to go into to roll temperature low, and in the expressing process, protein denaturation is little in the blank, thus protein content height in the grouts, the comprehensive utilization of favourable grouts.

Below be embodiments of the invention.

Peanut is shelled with peeling machine, select cleaning, full Semen arachidis hypogaeae from weigh vibratory screening apparatus and air draught than heavy-duty machine through bilayer.The Semen arachidis hypogaeae of cleaning out is made blank with three kinds of methods.The one, steam base, after promptly Semen arachidis hypogaeae being broken into the 4-8 lobe with grinder, roll into the thin stock of 0.4 millimeter with biconjugate roller crushing roll, then with the moistening thin stock of water of the caustic soda that contains 0.05-0.2% salt and Bo Meishi concentration 1 degree to moisture 14-16%, steam base with the laminar steamer with 90-100 ℃ at last; The 2nd, fry base, with flat bottom cooker with 100-120 ℃ of parch Semen arachidis hypogaeae after, roll into thin stock with biconjugate roller crushing roll; The 3rd, directly raw peanut kernel is rolled into thin stock.In the ratio of steaming base 40%, stir-fry base 30%, green compact 30% three kinds of thin stocks are mixed, send into the squeezing of 200 type power spin oil press zhai, go into to roll temperature and be controlled between 95-100 ℃, go into to press moisture controlled 40%.The pre-pressed cake residual oil content is controlled at about 12%, carries out multiple press for extracting juice again, and expressed oil flows into the oil-filtering box post precipitation, and top edible vegetable oil is pumped into the comb water cooler, is cooled to about 20 ℃, squeezes into pressure filter with triplex pump again and carries out press filtration.

Moistening owing to the steaming base has been carried out, make the phosphatide water-swelling cohesion in the blank, its solubleness in oil reduces, major part is stayed in the grouts during squeezing, go into to press and adopt " the high moisture content of low temperature " again, thereby kept the natural flavor of peanut, multiple press for extracting juice has then improved oil yield.

To steam base 50%, fry base 30%, the mixed squeezing of green compact 20% or steaming base 50%, stir-fry base 20%, green compact 30% can make peanut oil with pure fragrance equally.

The peanut oil with pure fragrance that makes is chemically examined through provincial grain and oil quality testing department: moisture content 0.07%, impurity 0.08%, acid value 0.32(mgKOH/g oil), peroxide value: 5.9(mg/kg) AFB ₁₅Below the PPb, heat test, oil colours is constant, and no precipitate reaches country-level peanut oil standard.

Claims
