The purpose of the present study was to investigate the effect of ethanol extracts from red pepper seeds on the antioxidative defense system and oxidative stress in rats fed a high fat high cholesterol diet. Rats were divided into four experimental groups which were composed of high fat high cholesterol diet group (HF), high fat high cholesterol diet with 0.1% ethanol extracts from red pepper seeds supplemented group (HEA), high fat high cholesterol diet with 0.2% ethanol extracts from red pepper seeds supplemented group (HEB) and high fat high cholesterol diet with 0.5% ethanol extracts from red pepper seeds supplemented group (HEC). Supplementation of ethanol extracts from red pepper seeds groups (HEA, HEB and HEC) resulted in significantly increased activities of hepatic glutathione peroxidase and catalase. Hepatic superoxide radical contents in microsome and mitochondria were significantly reduced in the groups supplemented with red pepper seeds ethanol extracts. Hepatic hydrogen peroxide content in the mitochondria was reduced in ethanol extracts from red pepper seeds supplemented groups. TBARS values in the liver were reduced in red pepper seeds ethanol extracts supplemented groups. Especially, HEB and HEC groups were significantly decreased compared to the HF group. Hepatic carbonyl values were significantly reduced in mitochondria in these supplemented groups. These results suggest that red pepper seeds ethanol extracts may reduce oxidative damage, by activation of antioxidative defense system in rats fed high fat high cholesterol diets.

This study produced instant Gochujang(red pepper paste) with enhanced convenience by increasing nutritional value and palatability, and by reducing production period, adding in the red pepper seed in the red pepper paste production in order to increase the use of the red pepper seed that is not used often as a food ingredient even though its nutrition value when producing red pepper paste was proven. Moisture content, pH, L-value, a-value, b-value, sugar contents, and salinity of instant Gochujang tended to increase as the amount of red pepper seed increased, while viscosity manifested the opposite trend. Sensory evaluations were conducted on instant Gochujang to assess differences in characteristics, which demonstrated that as the amount of red pepper seeds powder increased, the intensity of redness for the red pepper paste's external appearance, luster, spicy flavor and taste, and savory taste were evaluated strong. Meanwhile, fermentation value, which is red pepper paste's foremost weakness was evaluated as weak. Moreover, there was no difference in the size of the grain when compared to the contrast group consisting of regular red pepper paste. The results of preference test demonstrated that the RG3 with 30% of red pepper seed is optimal in terms of the external appearance, taste, texture and overall preference.

The purpose of the present study was to evaluate the effects of red pepper seeds powder on lipid metabolism in rats fed high fat high cholesterol diet. Rats were divided into five experimental groups: normal diet group, high fat high cholesterol diet group, high fat high cholesterol diet with 5% red pepper seeds powder supplemented group (SA group), high fat high cholesterol diet with 10% red pepper seeds powder supplemented group (SB group) and high fat high cholesterol diet with 15% red peeper seeds powder supplemented group (SC group). The serum triglyceride (TG) and cholesterol contents, and LDL-cholesterol and atherogenic index (AI) of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The serum HDL-cholesterol contents of the red pepper seed powder supplemented groups were increased compared to the HF group. However, there was no significant difference in the serum HDL-cholesterol among all experimental groups. The hepatic TG and cholesterol contents of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The fecal total cholesterol and triglyceride contents of the red pepper seeds powder supplemented groups were significantly increased compared to the HF group. These results suggest that supplementation of red pepper seed powder may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat high cholesterol diets.

Some Physico-chemical properties of korean red pepper seed oil were evaluated to find available method to utilize red pepper seeds used as useful cooking oil resources. Samples of red pepper seeds used as oil meterials were native, improved species and they were named such as NS (native spicies dried under sunlight), IS (improved spicies dried under sunlight), NF (native spicies dried by heating), and IF(improved spicies dried by heating), respectively. Moisture, ash, crude protein and crude fat contents of all red pepper seeds were 6.6%∼7.7%, 3.3∼3.5%, 18.25∼19.4% and 26.8∼27.5% in all samples, showing the specially high crude fat and crude protein content in NS. Capsaicin contents in crude red pepper seed oils were shown from 0.06 to 0.08% but after refining process, capsaicin contents were mostly tossed as 0∼0.006%. The types of tocopherol found in crude and refined red pepper seed oils were ${\gamma}$-, ${\alpha}$-, $\delta$-analogues, the amount of total tocopherol in IF was 2.10 mg/g oil which were the highest value of all red pepper seeds. In all red pepper seeds oils main fatty acids were linoleic acid (68∼70%), palmitic acid (14∼16%), oleic acid (10∼11%), and linolenic acid were extemely small amounts. The specific gravity (SG) 0.916∼0.919, refractive index (RI) 1.4724, acid value (AV) 0.26∼0.36, peroxide value (POV) 0.73∼1.19 and Iodine value (IV) 134.35∼134.92 were measured in all red pepper seed oils.

The purpose of the present study was to examine the effects of water extracts from red pepper seeds powder on antioxidative enzyme activities and oxidative damage in groups of rrats fed high-fat and high-cholesterol diets group (HFC). The Rrats were divided into the following five experimental groups which are : composed of a normal diet group, a high fat high cholesterol diet group, and a high fat high cholesterol diet group supplemented with different amounts contents (1%, 2% and 4%) of red pepper seeds powder water extracts supplemented groups (HFCW1, HFCW2 and HFCW4, respectively). Body weight gains and food intake were lower ofin the red pepper seed water extracts groups were lower than those inof the HFC group. Hepartic xanthine oxidase (XOD) activity was decreased in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic glutathione peroxidase (GSH-px) activitiyactivity was increased in the HFCW4 group compared to the HFC group. Hepatic superoxide radicals within the mitochondria and microsomes of cells were significantly reduced in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic hydrogen peroxide in the cytosol was significantly reduced in the HFCW3 and HFCW4 groups compared to the HFC group. Hepatic carbonyl values in the microsomes and mitochondria were significantly reduced in the HFCW4 group compared to the HFC group. Hepartic thiobarbituric acid reaction substance (TBARS) activity was decreased in the HFCW2 group compared to the HFC group. These results suggest that water extracts of red pepper seeds powder may reduce oxidative damage by activation of antioxidative defense systems in rats fed high fat-high cholesterol diets.

Four seed vetch (Vicia tetrasperma), a biennial native leguminous plant, was used for a cover crop with different quantity of sowed seeds. Weed suppression and yield were evaluated for the red pepper cultivation in the following year of the vetch seeding. Seeding of 1.0, 2.0, 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ suppressed weed occurrences until late in the growing season of the red pepper. Consequently, red pepper in the cover cropping system with seeding of 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ had a similar yield to the conventional red pepper. The ideal seed rate in four seed vetch was 3.0 and 4.5 kg 10 $a^{-1}$ in terms of reducing weed occurrence as well as increasing growth and yield in red pepper.
