Abstract

The invention discloses a processing method for producing peanut oil. The processing method comprises the steps of airing, grinding, heat preservation, cake making, steaming, squeezing and filtering. Particularly, peeled peanut kernels are taken and aired, and dried peanut kernels are obtained; the dried peanut kernels are sealed in a container after being ground by a crushing mill; heat preservation is carried out for two hours at the temperature of 55+/-5 DEG C, and cakes are made and placed in a steamer, and is steamed with steam; the steamed peanut kernels are squeezed to obtain crude oil; the crude oil is precipitated for 36-48 hours, and finished oil is obtained after filtering. The peanut oil is strong and mild in flavor, high in monounsaturated fatty acid and beneficial to body health after being eaten for a long time, and high nutritive value and the healthcare function are achieved.

Description

A kind of working method of producing peanut oil

Technical field

The present invention relates to a kind of working method of edible oil, being specifically related to a kind of take peanut as the working method of raw material production peanut oil.

Background technology

Peanut oil is yellowish transparent, and color and luster is limpid, fragrant, and flavour is good to eat, is a kind of more readily digested edible oil.Peanut oil is containing unsaturated fatty acids more than 80% (wherein containing oleic acid 41.2%, linolic acid 37.6%).In addition also containing Palmiticacid, the saturated fatty acid such as stearic acid and eicosanoic acid 19.9%.The Fatty acid compositions of peanut oil is reasonable, is easy to human consumption and absorption.

At present, the production method of peanut oil has water substitution, milling process.Traditional water substitution technique is: clear benevolence, moisten benevolence, fry benevolence, raise cigarette, convert slurry and stir the step such as oil, oil separation by oscillation, the peanut oil produced is with rich flavor, soft, but its labour intensity is large, and produce a large amount of waste water and can not realize continuous prodution, development is restricted.The machine that grew up afterwards squeezes technique: clear benevolence, fry seed, raise cigarette, modified, squeezing, filtration, the step such as precipitation, although compensate for the deficiency of water substitution, there is automatic control level high, can the advantage such as continuous prodution, but the peanut oil local flavor produced do not have water substitution to produce peanut oil is soft, pure.Traditional peanut oil production technology is by after parch maturation mostly, and the output peanut oil through high temperature squeezing, nutrition and the active substance of institute's produce oil can incur loss, and oil yield rate and oil all can be affected, and its natural fragrant also can be affected.

Summary of the invention

The object of the present invention is to provide a kind of working method of producing peanut oil, the peanut oil that the method is produced is with rich flavor, soft, and nutritious, can continuous prodution.

A kind of working method of producing peanut oil of the present invention, comprises the following steps:

A airing: the Semen arachidis hypogaeae removing shell, carries out airing to it, controls water ratio 3%-5%, obtains drying peanut rice;

B mills: the drying peanut rice grain pattern of step a is crossed pan mill and pulverizes, and obtains Semen arachidis hypogaeae and grinds grain;

C is incubated: the Semen arachidis hypogaeae of step b is ground grain and is sealed in container, under the condition of 55 ± 5 DEG C, be incubated 2 hours;

D cake: the insulation Semen arachidis hypogaeae of step c is ground grain and makes cake;

E boiling: be placed in food steamer by the cake of steps d, by water vapour boiling 0.5-1 hour;

F squeezes: carried out squeezing and obtaining crude oil by the peanut cake after step e boiling;

G filters: crude oil precipitation obtained for step f filtered after 36-48 hours, namely obtain processed oil.

In described step g, crude oil filters is evenly filtered through flame filter press, to remove impurity by crude oil.

Technique scheme has the following advantages:

The present invention is with pure natural Semen arachidis hypogaeae for prepared by raw material, does not add any objectionable constituent, belongs to green health food; The product unsaturated fatty acid content of preparation is high, and retains the beneficiating ingredients such as wheat germ phenol, phosphatide, vitamin-E, choline; Preparation process is simple, and production cost is low, and particularly processing condition are gentle, fully can retain the prototroph composition of Semen arachidis hypogaeae; Oil yield is high, and the peanut oil obtained is not containing organic solvent, and the various effective constituents in peanut oil are not damaged, and use value is higher; Except containing abundant unsaturated fatty acids, as outside linolenic acid, linolic acid, also containing various bioactivators such as plant sterol, amino acid, VITAMIN, mineral substance, especially zinc, magnesium, calcium, phosphorus content are high.

Embodiment

Below in conjunction with specific embodiment, a kind of working method of producing peanut oil of the present invention is described further.

Embodiment 1:

A airing: 1000 kilograms, the Semen arachidis hypogaeae removing shell, carries out airing to it, controls water ratio 3%-5%, obtains drying peanut rice;

C is incubated: the Semen arachidis hypogaeae of step b is ground grain and is sealed in container, under the condition of 50 DEG C, be incubated 2 hours;

E boiling: be placed in food steamer by the cake of steps d, by water vapour boiling 0.5 hour;

G filters: filter after the crude oil that step f is obtained is precipitated 36 hours, obtained processed oil 450 kilograms.

Embodiment 2:

C is incubated: the Semen arachidis hypogaeae of step b is ground grain and is sealed in container, under the condition of 60 DEG C, be incubated 2 hours;

E boiling: be placed in food steamer by the cake of steps d, by water vapour boiling 1 hour;

F squeezes: carried out squeezing and obtaining crude oil by peanut cake after step e boiling;

G filters: filter after the crude oil that step f is obtained is precipitated 48 hours, obtained processed oil 480 kilograms.

Peanut oil prepared by the present invention, its monounsaturated fatty acids is higher, and life-time service is conducive to healthy; In addition, also containing the various bioactivators such as plant sterol, amino acid, VITAMIN, mineral substance, especially zinc, magnesium, calcium, phosphorus content are high, have the function that good delay human body cell is old and feeble, retain youth; Frequent edible peanut oil, can prevent wrinkled skin aging, and protection vessel wall, prevents thrombosis, contributes to prevention of arterial sclerosis and coronary heart disease; Meanwhile, the choline in peanut oil, also can improve the memory of human brain, delay brain function decline.

Claims

1. produce a working method for peanut oil, comprise the following steps:

2. a kind of working method of producing peanut oil according to claim 1, is characterized in that: in described step g, crude oil filters is evenly filtered through flame filter press, to remove impurity by crude oil.
