Samples of Trout dived into aqueous extract of ginger in different
concentrations (5-15-25)% for one minute and then preserved at 4±1
cº for 13 days. It has studied the effect of aqueous extract of ginger
in bacterial load, including general bacterial census and the census
of pseudomonas. It was also identified the values of the pH and
some organoleptic qualities of meat such as color, smell, texture and
taste.
It was used in this study (15) of the female mice . They were divided into three
groups : control , and two experimental groups (five mice in each group) .The control
group was given distilled water, while the first experimental group was received
only
Paraben daily ( 250 mg / kg of body weight). As the second experimental group was
received daily together of Paraben and aqueous ginger extract ( 250 mg / kg of paraben and
250 mg / aqueous ginger extract ) for (18 ) day .
Decreasing serum lipids is still blocked by chemical drugs which have many
side effects, and to achieve a safe medicine, this study aims to investigate the act of aqueous extracts of
dried and fresh Zingiber officinale roscoe at tow doses on the le
vels of total cholesterol, HDL high-density
cholesterol, LDL low-density cholesterol, and TG triglycerides in rat with hypercholesterolemia, resulting
from hypothyroidism, caused by propyltheouracil PTU.
Some local natural sources of antioxidant such as orange peel extract (Citrus
sinensis), pomegranate peel extract (Punica granatum) and ginger extract
(Zingiber officinale L.) were evaluated during 5 days storage of refined palm oil
at 63°C as com
pared to the synthetic antioxidant such as propyl gallate. The
above extracts were obtained with ethanol and oil (palm oil). Those extracts
were added to the oil at two different levels (100 ppm and 200 ppm).
Antioxidant activity of natural extracts, synthetic antioxidant and the control
treatment without antioxidant under thermal treatment (Schaal test) was
assessed by measuring acid value (AV), peroxide value (PV), iodine value (IV)
and refractive index (RI) during 6 days storage of refined palm oil at
temperature mentioned above. Antioxidant activity also measured by studying
the stability of oil by the use of rancimat method. All treatments exhibited
antioxidant activity. Statistical analysis results were shown that the
pomegranate peel extract treatment was significantly (P<0.05) superior than
the orange peel extract and ginger extract treatments whereas, it was not
significant difference about propyl gallate treatment.
