aggregation, and various cardiovascular diseases. Ozkal and Dinc (1994)
reported the presence of tannins, anthocyanins, and flavonoids in pome-
granate rind. Pomegranate peel is a rich source of tannins and other phenolic
compounds. The utilization of pomegranate fruits for meat processing and
its potential health benefits are not well understood. The meat industry can
use these fruits or fruit byproducts as a potential source of phenolics as they
have immense nutraceutical value and can be used to produce functional
meat products of commercial interest (Naveena et al., 2008; Vaithiyanathan
et al., 2011).

5.3.1.30 POTATO PEEL EXTRACT (PPE)

The effective utilization of potato peel, a waste generated in large quantities
by the food industry, as an antioxidant in radiation processed lamb meat
was investigated by Kanatt et al. (2005). PPE has a high phenolic content
(70.82 mg, catechin equivalent/100 g), chlorogenic acid (27.56 mg/100 g
of sample) is the major component. The yield of total phenolics and chlo-
rogenic acid increased by 26 and 60%, respectively, when the extract was
prepared from γ irradiated (150 Gy) potatoes. The AOA of PPE was found
to be comparable to BHT.

5.3.1.31 RAPESEED MEAL

Rapeseed meal contains α-tocopherol (52 μg/g) and phenolic hydroxycin-
namic acid derivatives including sinapine (2400–2900 μg/g) and sinapic
acid (280 μg/g) which inhibit hexanal formation (≥85%). It is also used in
combination with commercial CO extract of rosemary (0.04 g/100 g meat)
2
and was excellent in prevention of oxidation of meat lipids (Salminen et al.,
2006).

5.3.1.32 RICE HULL EXTRACT

Rice hull can be an attractive protective source because it contains many
easily extractable antioxidant compounds. Furthermore, radiation of rice
hull with far infrared (FIR) for 2 h increased the content of phenolic
compounds in extract. FIR radiation onto rice hull is reported to liberate
