The Best Natural Antioxidant For Human
on 21th Century
LSTP-lipid
soluble tea polyphenols, extracted from green tea.
A natural antioxidant for oil,fat,cosmetics,etc.
a. What is the LSTP?
LSTP is a natural antioxidant
extracts from Chinese green tea by special technology . It has
outstanding antioxidation and keeping its quality effect to heavy
oil foods and edible oil ,better than BHA.BHT. and Ve ,sesamephenols
and so on .Some oil riched foods , such as fried potato flakes ,
corn flakes ,contain about 50% of oil and possess very large surface
area ,thus it is very easy for them to be oxidant and spoiled .you
should use anti-oxidant to protect them .LSTP is the first selected
antioxidant to be used in best edible oil to keep original quality
increasing transparency and brightness ,prolong time limit of good
on shelves A general amount added was 50-1000ppm.
b. The Anti-Oxidate Principle of LSTP:
The Anti-Oxidate principle of
LSTP as follows
|
|
The main component of LSTP is
Catechins, has excellent antioxidant and great physilogical activity
.There are active hydroxyl groups inside LSTP ,when the Catechins
oxidated into quinone-structure ,which can provide H+ protons to
combine with oxidated free radicals ,so as to get rid of the excess
of free radicals ,In such way ,the fat and oil can be prevented from
being further oxidated.
c. PROPERTIES:
1. This powder product
can dissolve in oils clear and completely .The oil can remain its
original color and odor and tastes better .
2. Its antioxidation
is 3-9 times than BHA,BHT,and 10-20 times Ve.
3. LSTP showed a
good antioxcidative effect on fat and oil .It can obviously prevent
foods to fade and increase the stability of vitamin and transparence
of oils. Additionally , it can raise the temperature of varieties of
oils smoke points greatly .
4. LSTP can showed synergetic effect
with Vc and make better effect .
5. LSTP is stable in warm and
acid circumstance ,although it may discompose in condition of
heating for long time .
6. 200ppm LSTP as antioxidant. Its
capability of antibactery is 200 times stronger than alcohol .
7.
It has prominent effect on action of medicine and keeping healthy .
It can cure cardiovascular and cerebral vascular diseases
,anticancer ,decreasing the blood ester ,enhancing immunity
,prolonging life .
d. METHODS OF USE
The most important
principle of adding LSTP in food or oil is making sure its complete
dissolution and well distribution in fat and oil . How to ensure oil
or food against oxidation depends on the method of adding LSTP ,and
the method varies with the products ,processes and equipments
.
By dissolving LSTP into small amount of fat or oil (at
temperature of 95- 115¡æ) .You can make concentrated LSTP solution
.Add this kind of LSTP concentrated solution to oil directly or to
liquid oil through measuring device ,and stir till it is well
distributed . (do not stir strongly so as not to permeate excessive
air)
For example:
In modern and automatic plants,for example
,its production capacity daily is 100mt ,and need
First, caculate
the quantity of LSTP: Q=100MT x200ppm =20 kg
Second,add 20kg
LSTP into 50kg oil, then heat it till 95-115¡æ,and stir it.
Third,
add above oil into 100mt oil accoding to flow-speed of the
oils.
in semi-automatic and non-automatic plants, proportionly
add the LSTP into the oils directly under the 95-115¡æ,then stir
it.
e. A general Adding Quantity of LSTP :50PPM-1000PPM
Plant
oils:
We have done a study between the soybean oil and rapeseed
oil, found that antioxidation of soybean oils 1/3 time higher than
antioxidation of rapeseed oils under the conditions of without
adding any antioxidant. so we need adding different quantity (LSTP)
to different types plant oils;because of the effect of the
ultraviolet ray,it is necessary to add different quantity for
different packing: For example:
the Guaranteed periods exceeding
18 months,need quantity of LSTP :
Soybean oils packed with
non-transparent drum (anti-ultraviolet ray):50PPM
Soybean oils
packed with transparent drum: 100PPM
Rapeseed oil packed with
non-transparent drum (anti-ultraviolet ray):80ppm
Rapeseed oil
packed with transparent drum :120ppm
Animal oils:
the
Guaranteed periods exceeding 18 months,need quantity of LSTP
:
pig oils:500PPM
fish oils:1000PPM
butter:300PPM |

antioxidant in salad oil(AOM method)
a. the Time for reaching
100meq/kg POV in rapeseed salad oil by Active Oxygen
Method(see,chart 1)
rapeseed salad oil without any additive:16.2
hours
rapeseed salad oil with 100ppm LSTP :26.4 hours
