Description

A kind of Rattan pepper oil complex antioxidant
Technical field
The invention belongs to food keeping technology field, particularly a kind of Rattan pepper oil complex antioxidant.
Background technology
Rattan green pepper is the peculiar spice crop in Sichuan, and its main chemical compositions has alkaloid, acid amides, lignanoid, tonka bean camphor, volatile oil and lipid acid etc.Rattan green pepper fresh fruit pericarp oil-containing reaches 8% ~ 15%, and having strong spicy hot taste, is seasonings important in Sichuan cuisine.The extremely difficult storage of rattan green pepper fresh fruit, uses so be often made into Tengjiao oil.Tradition Tengjiao oil produces main use decoction method and deep fat infusion method, length consuming time, requirement temperature is high, and prepared Tengjiao oil water content is low, and Tengjiao oil storage effect is better, but fragrance matter volatilization is many, Tengjiao oil insufficient fragrance, second-rate, in order to meet the rattan green pepper raw material that market quality requires that usually needs are a large amount of, cause raw-material waste, production efficiency is low.In recent years in order to improve Tengjiao oil fragrance matter content, promoting Tengjiao oil quality, improving the utilization ratio of rattan green pepper raw material, production control cost, usually take the method reducing temperature extraction.When Extracting temperature is lower, fragrance matter volatilization is less, aromatic flavour, but water content is high, very easily produces free radical, causes acid value and peroxide value to raise rapidly, and being everlasting, it is rotten namely to occur in a short time becoming sour, and affects quality product, causes quality problems.Therefore develop a kind of economically viable Tengjiao oil storage preservation method, both ensured Tengjiao oil fragrance and quality, Tengjiao oil acid value and peroxide value can be made again to rise slowly thus extend the Tengjiao oil quality guaranteed period, is the task of top priority.
Summary of the invention
The object of the invention is for the above demand for extending the Tengjiao oil quality guaranteed period, a kind of Rattan pepper oil complex antioxidant is provided, can make Tengjiao oil under the condition of airtight, unglazed photograph, 20 DEG C of temperature, extending shelf lives to two year, is a kind of economically viable Tengjiao oil method for preserving.
In order to reach above object, the present invention adopts following technical scheme:
A kind of Rattan pepper oil complex antioxidant, the mixture be made up of according to a certain percentage TBHQ, AP and BHT tri-kinds of antioxidants, its per-cent accounting for Tengjiao oil quality is respectively:
TBHQ 0.01~0.015%;
AP 0.001~0.0075%;
BHT 0.001~0.0075%;
The summation of three kinds of oxidation preventive contents is no more than 0.02% of Tengjiao oil quality.
Adding antioxidant is one of technology of conventional control oil quality in foodstuffs industry, namely utilizes the artificial antioxidant added to block the transmission of free radical or electronics, the rising of suppression peroxide value and acid value.And use composite antioxidant, can the various antioxidant of full use used in combination time produce " synergy ", significantly improve antioxidant effect.Existing multiple example using mixing antioxidant to control oil quality both at home and abroad, but not yet have composite antioxidant for the relevant report of Tengjiao oil quality control.
TBHQ: tertiarybutylhydroquinone, be the edible antioxidant that national regulation allows to add, have safer nontoxic performance, addition is few, has good antioxidant effect to vegetables oil.
AP: Quicifal, can be able to stop superoxide in grease to be formed with free radical reaction, is the food antioxidant that China allows to use.
BHT:2,6-di-tert-butyl-4-methy phenol, is the food antioxidant that China allows to use, has good antioxidant property to vegetables oil.
Use composite antioxidant to reduce antioxidant usage quantity, improve economic and social profit there is very significant meaning.
As preferably, the per-cent that described three kinds of antioxidants account for Tengjiao oil quality is respectively: TBHQ 0.01%, AP 0.005%, BHT 0.005%.
As preferably, the per-cent that described three kinds of antioxidants account for Tengjiao oil quality is respectively: TBHQ 0.01%, AP 0.0075%, BHT 0.0025%.
As preferably, the per-cent that described three kinds of antioxidants account for Tengjiao oil quality is respectively: TBHQ 0.01%, AP 0.0025%, BHT 0.0075%.
As preferably, the per-cent that described three kinds of antioxidants account for Tengjiao oil quality is respectively: TBHQ 0.015%, AP 0.0025%, BHT 0.0025%.
Before adding composite antioxidant, the quality control of Tengjiao oil is: acid value is not higher than 1, and peroxide value is not higher than 3, and water content, not higher than 0.2%, is cooled to room temperature.
If use this composite antioxidant when high temperature, poor effect.
Same batch of Tengjiao oil is used to be mixed with the mother liquor that massfraction is 1% described three kinds of antioxidants, simultaneously mechanical stirring more than 2000 turns, time remaining more than 20 minutes; And then add in Tengjiao oil according to required ratio, mechanical stirring more than 2000 turns while interpolation, time remaining more than 20 minutes.
During use, Tengjiao oil and composite antioxidant mother liquor need fully to mix.
After described composite antioxidant is added Tengjiao oil, by Tengjiao oil airtight storage under lucifuge, 20 DEG C of conditions.
Described in the application, the beneficial effect of technology is:
The present invention filters out TBHQ, AP and BHT tri-kinds of antioxidant mixing formulas being applicable to Tengjiao oil preservation and has significant antioxidant effect, effectively can control the rising of acid value and peroxide value in Tengjiao oil, reduce the impact of moisture on acid value and peroxide value, make Tengjiao oil can under airtight, unglazed photograph, the temperature condition of 20 DEG C, extend the shelf life to more than 2 years, make and use simple, cost is low, for Tengjiao oil quality control provides economically viable method for preserving, there is good economic and social benefit.

evaluation Example:
Adopt the compound anti-oxidation agent prescription described in embodiment 1-6 respectively, not add antioxidant for blank and other concentration antioxidants are for contrast, carry out antioxidant effect test.
Schaal baking oven laboratory method is adopted to carry out accelerated test to each sample.The each sample that same day is obtained is positioned in baking oven, and temperature is 60 ± 1 DEG C, and distinguish acid value and the peroxide value of working sample at set intervals, METHOD FOR CONTINUOUS DETERMINATION repeatedly, and records result.Acid value and determination of POV are see GB relating operation.
Experiment detailed data is in table 1, table 2.
The impact that table 1 different treatment changes Tengjiao oil acid value
Table 2 different treatment is on the impact of Tengjiao oil peroxide value
With Tengjiao oil quality provincial standard: Tengjiao oil acid value (mg/g)≤3.0, peroxide value (meq/kg)≤12.0 is standard, it is known when accelerated test proceeds to 47 days, under various process, acid value all meets relevant criterion, but preservation can cause peroxide value significantly to raise for a long time, only has the compound anti-oxidation agent prescription described in this patent embodiment 1-6 can ensure that peroxide value does not exceed standard.
According to Arrhenius equation,
K(T+10℃) =Q 10×K(T),
K(60℃)=Q 10 4×K(20℃),
Under normal circumstances, Q 10=2,
K(60℃)=16×K(20℃)
The compound anti-oxidation agent prescription that can calculate described in this patent can ensure Tengjiao oil preservation 47(days) × 16=752(days) more than, be more than 2 years after conversion.
In sum, Rattan pepper oil complex antioxidant of the present invention significantly can suppress the acid value of Tengjiao oil in preserving process, peroxide value raises, and significantly extends the Tengjiao oil quality guaranteed period.
