The Best Natural Food Antioxidant
Being resistant to high temperature enables the extract to replace
synthetic food preservative like BHA and BHT.
Different from green tea extract, rosemary extract possesses light-
er colour and odour, so it won’t exert unpleasing influences on the
appearance and taste of food.
The extract can inhibit oils from rancidity, and prevent carotenoids
from fading, thus extending shelf life.
It can keep overcooked or crushed poultry and fish out of warmed-
over flavour, and improve the taste of low-PH sauces.
The extract can inhibit carcinogens while people are cooking food.
Effectively antibacterial rosemary extract can kill E. coli, Vibrio
cholerae and so on.

The oxidation resistance of rosemary extract is 2 ~ 4 times
stronger than BHT and BHA
The oxidation resistance of rosemary extract is better than VE.
Rosemary extract can inhibit the oxidation of epidermal
lipids, helping anti-aging agents keep our skin firm and
glossy. The performance can be as good as SOD, but
without the instability of enzymes.
As carnosic acid is able
to retain hyaluronic acid
on skin for longer time,
it’s an excellent addi-
tive.
Rosemary extract can
stimulate the blood
circulation of scalp and the growth of hair, reduce dan-
druff, so thus relieving hair loss. For this reason, the
