  • This study was conducted to investigate the effects of cranberry power on antioxidant defense system in rats fed an atherogenic diet and injected with lipopolysaccharide (LPS). Sprague-Dawley rats were divided into the following 5 groups: normal diet+saline (NS), atherogenic diet+saline (AS), atherogenic diet+LPS (AL), atherogenic diet with 5% cranberry powder+LPS (AL-C5), and atherogenic diet with 10% cranberry powder+LPS (AL-C10). Total antioxidant status measured by ferric reducing ability of plasma (FRAP) was significantly reduced by LPS injection (24%) and was restored by the cranberry powder treatment (P<0.05). In addition, the mean level of plasma total phenolics was significantly decreased by LPS injection (P<0.05) and tended to be increased when cranberry powder was incorporated in to the diet. Activity of serum superoxide dismutase (SOD) tended to be lowered by LPS injection and declined further in cranberry powder fortified groups. Overall results indicate that dietary cranberry powder may provide appropriate antioxidants to counter the diminished antioxidant status induced by exposing hypercholesterolemic rats to LPS.

  • This study investigated that the antioxidative effect of freeze-dried cranberry powder against protein and lipid oxidation and ameliorative effect of serum lipid profile in rat fed atherogenic diet. Six weeks old male Sprague-Dawley rats were divided into the following four groups: normal diet group with 5% com oil(control), atherogenic diet group with 5% com oil, 10% lard, 1% cholesterol, and 0.5% sodium cholate(HFC), atherogenic plus 2% cranberry powder diet group(HFC+C2), and atherogenic plus 5% cranberry powder diet group(HFC+C5), and respective diet and water were fed daily for 6 weeks. After the experimental period, the serum lipid profile, such as total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride, ferric reducing ability of plasma(FRAP), plasma phenolics content, superoxide dismutase(SOD) activity, serum protein carbonyl and thiobarbituric acid reactive substances(TBARS) levels were examined. Total phenolic compound and total flavonoid levels in freeze-dried cranberry powder were 9.94 mg/g and 8.12 mg/g, respectively. Serum total cholesterol and LDL-cholesterol levels were not significantly different for cranberry powder treatment, but serum HDL-cholesterol level was significantly increased in HFC+C5 group compared with HFC group. Plasma FRAP value tended to be increased by cranberry powder treatment though there was no significant difference. Plasma total phenol concentrations and SOD activities were not significantly different among all groups. Serum protein carbonyl and TBARS levels were significantly decreased in HFC+C5 group compared with HFC group. Overall results suggested that freeze-dried cranberry powder might have the serum lipid improving effect, as well as anti oxidative effect demonstrated by its protective effect against protein and lipid oxidation.

  • This study was designed to investigate the effect of cranberry powder making pan bread. Cranberry powder at the level of 1 % (CP1), 3% (CP3), and 5% (CP5) was mixed with flour to make the breads. According to mixograph, the control, CP1 and CP3 except CP5 were found to bo proper between 3 and 5 min. in tenn of peak time (min). All samples for peak value were at the level of over 60% It meant that all samples were proper to make bread. By increasing the ratio of cranberry powder, pH, dough fermentation rate, volume and specific volume were decreased, and adhesiveness, springiness, cohesiveness and resilience except hardness were decreased in texture profile analysis. In crumbScan analysis, the addition of cranberry powder decreased the volume and increased crumb fineness of pan bread. In sensory evaluation, CP1 and CP3 showed good preference in aspect of flavor, taste, and overall acceptance.

  • This study investigated the effects of freeze-dried cranberry powder on anti-inflammation and lipid profiles of lipopolysaccharide (LPS)-treated rats fed an atherogenic diet for 6 weeks. Forty Sprague-Dawley male rats (6-weeks-old) were equally divided into the following five groups: 1) normal diet group+saline (NC); 2) atherogenic diet+saline (HFC); 3) atherogenic diet+LPS (HL); 4) atherogenic diet with 5% cranberry power+LPS (C5); 5) atherogenic diet with 10% cranberry power+LPS (C10). LPS (0.5 mg/kg) was injected into the abdominal cavities of rats 18 hours prior to sacrifice. At the end of the experimental period, we measured serum lipid profiles as well as levels of serum C-reactive protein (CRP), nitric oxide (NO), and pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-1${\beta}$, IL-6, and IL-10 as an anti-inflammatory cytokine. The mean serum high density lipoprotein (HDL)-cholesterol level in C5 rats was significantly higher than that in NC and HL rats (P<0.05). The mean serum levels of CRP and IL-1${\beta}$ were significantly lower (P<0.05) in the cranberry powder groups compared to those in HL rats. Additionally, mean serum IL-6 levels tended to be lower in the cranberry groups than that in the HL group, whereas serum IL-10 and NO showed 29% and 88% higher mean values in the C5 group and 49% and 24% higher in the C10 group than those in the HL group, respectively. These results suggest that freeze-dried cranberry powder may have beneficial effects on cardiovascular diseases by modifying serum lipids and the early inflammatory response.

  • The objective of this study was to determine antioxidant properties of polyphenol fractions of cranberry powder employing lipopolysaccharides (LPS)-stimulated RAW264.7 macrophage cells. Ethyl acetate fraction (EF) and methanol fraction (MF) of cranberry powder were prepared using a C18 Sep-Pak cartridge. When cells were treated with LPS for 20 h, intracellular reactive oxygen species (ROS) and DNA damage significantly increased. In cells pre-treated with EF, MF, and total fraction (TF: combining EF and MF), significant reductions of intracellular ROS were observed. The tested fractions reduced LPS-induced DNA damage measured by Hoechst staining. In addition, LPS-induced DNA oxidation was attenuated when cells were pre-treated with TF and MF. However, there was no significant difference in LPS-induced superoxide dismutase activity.

  • Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.

  • The feasibility of incorporating cranberry powder (CP) as a value-added food ingredient in cookies was investigated. The moisture content and spread ratio of cookies increased significantly with increasing levels of CP (p<0.05). Lightness and yellowness decreased, whereas redness increased significantly with higher amount of CP. The use of CP significantly decreased the hardness of cookies while 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity was significantly elevated. The consumer acceptance test indicated that the addition of CP up to 4% had a favorable effect on the consumer preferences in most attributes. Based on the overall observations, cookies with 4% CP can take advantage of the functional properties of CP without sacrificing consumer acceptability.
