Abstract
The present invention discloses a kind of method for extending perilla oil shelf life, the grease store method is that 0.01--0.02%TBHQ, 0.005%--0.01%- citric acid, 0.01%-0.1% degreasing Fructus Perillae extract are added into grease to be saved, to extend the storage period of perilla oil.What is added in this method is all very safe or natural antioxidant, can interrupt the radical chain reaction of active oxygen initiation, to inhibit the oxidative rancidity of grease and play the role of extending perilla oil storage life, extends perilla oil shelf life.
Description
Technical field
The present invention relates to oil and fat chemical field more particularly to grease Techniques of preserving, i.e., a kind of extension perilla oil shelf life
Method.
Background technique
Essential fatty acid-alpha-linolenic acid in perilla oil rich in our human bodies can be converted in vivo up to 60% or more
Function factor DHA and EPA.With antithrombotic and reducing blood lipid, prevention canceration and inhibits Nasopharyngeal neoplasms and inhibit abnormalism
The effect of illness, long-term consumption can the extending life phases.China's Perilla is abundant, to develop and utilize the resource, first have to solve
Certainly the problem of is exactly the anti-oxidant problem of perilla oil.
What is contained in perilla oil is nearly all unsaturated fatty acid, accounts for 90% or more.Especially due to unsaturated fatty acid
Alpha-linolenic acid content is high, it is easy to be oxidized, so that its original flavor taste can be lost, or even can also generate ketone, aldehyde, alcohol etc.
To the substance of human health, therefore how research inhibits the oxidation of perilla oil to extend the shelf life tool of perilla oil
There is extremely important meaning.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of methods for extending perilla oil shelf life.
Technical scheme is as follows:
A method of extend perilla oil shelf life, which is characterized in that into perilla oil to be saved add TBHQ,
Citric acid (CA), degreasing Fructus Perillae extract, perilla oil is bottled, then nitrogen is filled with into bottle, add after stirring
Lid is sealed.TBHQ in perilla oil, degreasing Fructus Perillae extract, CA additive amount be respectively 0.01-0.02% perilla seed
Oil quality, 0.01-0.1% perilla oil quality, 0.005-0.01% perilla oil quality.
Preferably, TBHQ in perilla oil, degreasing Fructus Perillae extract, CA additive amount be respectively 0.02% perilla oil
Quality, 0.01% perilla oil quality, 0.005% perilla oil quality.
In order to reach superior technique effect:
Degreasing Fructus Perillae extract the preparation method comprises the following steps: by perilla seed it is sufficiently dry after pulverized with mortar, be packed into cable-styled mentions
Device is taken, petroleum ether is used to flow back as solvent, removes fat.Residue after fetching stream, with alcohol steep three days three of 75%
Night is collected by filtration leaching liquor and carries out being concentrated into ethyl alcohol all volatilizations.
TBHQ, CA, degreasing Fructus Perillae extract are dissolved in together in a small amount of dehydrated alcohol.
The above-mentioned ethanol solution dissolved with additive is mixed into the grease by stirring, grease is heated to 40-60 DEG C,
Side stirring simultaneously, mixing time 20-30 minutes.
The bottle of dress perilla oil, which has, is protected from light effect, and bottle cap needs to seal air tight after covering tightly.
Perilla oil storage temperature is 10-25 DEG C.
The present invention removes the addition safety into perilla oil and extremely increases in the antioxidant TBHQ that FAO/WHO evaluates category A class
It imitates outside agent citric acid, is also added to the degreasing Fructus Perillae extract rich in flavones and polyphenol compound, three kinds of additions thereto
Agent has collaboration antioxidation in perilla oil.Simultaneously perilla oil take starvation and be protected from light and cryogenic conditions under,
Any harm will not be not only brought to human health, moreover it is possible to the shelf-life of perilla oil be made to extend to two from original 10 months
Nian Duo.
Detailed description of the invention
Fig. 1 different additive influences perilla oil oxidation stability
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiments described below is only used for
The description and interpretation present invention, is not intended to limit the present invention.
Embodiment 1
1, degreasing Fructus Perillae extract the preparation method comprises the following steps: by perilla seed it is sufficiently dry after pulverized with mortar, be packed into cable-styled
Extractor uses petroleum ether to flow back as solvent, removes fat.Residue after fetching stream, with 75% alcohol steep 72h,
Leaching liquor is collected by filtration to carry out being concentrated into ethyl alcohol all volatilizations.
2, it is spare to weigh 50g perilla oil.
3, additive prepares: weighing perilla oil weight 0.02%TBHQ, 0.005%CA, 0.01% degreasing perilla seed extracts
Object is dissolved in a certain amount of dehydrated alcohol and making it completely dissolved.
First group is 0.01g TBHQ；That is oil weight 0.02%TBHQ；
Second group is 0.0075g degreasing Fructus Perillae extract；I.e. oil weighs 0.015% degreasing Fructus Perillae extract；
Third group is 0.005g TBHQ, 0.0025g degreasing Fructus Perillae extract；That is oil weight 0.01%TBHQ, oil weight
0.005% degreasing Fructus Perillae extract；
Every group is added 0.0025g CA i.e. oil weight 0.005%CA again, is dissolved in ethanol solution respectively, spare.
4, perilla oil is heated to 40-60 DEG C, will be respectively added in three parts of oil dissolved with the ethanol solution of additive, and
It persistently stirs 30 minutes, evenly distributes additive in perilla oil, and ethyl alcohol is allowed sufficiently to volatilize.
5, perilla oil is fitted into the sealed glass jars being protected from light, is placed in 63 DEG C of baking ovens, Acceleration study is carried out to grease,
The group is as experimental group.
6, separately claim 50g perilla oil to be fitted into sealing to be protected from light in vial, equally be placed in 63 DEG C of baking ovens, as blank control
Group.
6, every the peroxide value variation of three days primary two groups of perilla oils of measurement, the measurement of peroxide value is referring to GB/T
5009.37-2003 animal and plant fat peroxide value carries out.
Above-mentioned experimental result is as shown in Figure 1:
As seen from Figure 1, each additive influences sequence to the inoxidizability of perilla oil are as follows: degreasing Fructus Perillae extract
+ citric acid < TBHQ+ citric acid < TBHQ+ citric acid+degreasing Fructus Perillae extract.According to Schaal Oven Method, perilla oil
It is put into be equivalent within one day in 63 DEG C of baking ovens at 10-15 DEG C and store one month, be added to adding for three kinds of compoundings as can be seen from Figure
After adding agent, since three kinds of additives have collaboration antioxidation, the shelf life of oil product, the shelf of perilla oil are substantially prolonged
Phase increased to more than 2 years from 10 months.
