  • This study examined the anti-diabetic effect of onion (Allium cepa. Linn) in the streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal rats fed control diet or supplemented with onion powder (7% w/w) and diabetic rats fed control diet or supplemented with onion powder. Diabetes was induced by a single injection of STZ (60 mg/kg, ip) in citrate buffer. The animals were fed each of the experimental diet for 5 weeks. Blood glucose levels of rats supplemented with onion were lower than those of rats fed control diet in the diabetic rats. Onion also decreased the total serum lipid, triglyceride, and atherogenic index and increased HDL-cholesterol/total cholesterol ratio in the diabetic rats. Glutathione peroxidase, glutathione reductase and glutathione S-transferase activities were high in the diabetic rats compared to normal rats and reverted to near-control values by onion. These results indicate that onion decreased blood glucose, serum lipid levels and reduced renal oxidative stress in STZ-induced diabetic rats and this effect might exert the anti-diabetic effect of onion.

  • This study was performed to examine the effects of onion powder supplementation on lipid metabolism in male SD rats fed a high fat and high cholesterol diet. Experimental groups were control (C), high fat fed group (HF), high fat+onion powder intake (OP), high fat+quercetin intake (Q). The HF diet contained 1% cholesterol, 4% lard, 0.3% Na-taurocholate, and quercetin supplementation level was 0.1 g/kg diet. The OP group showed lower body weight gains compared to the control, while there was no significant difference in food efficiency ratio efficiency. When the proportion of fecal bile acids per total lipids was calculated, there was a significant decrease in the HF group compared to the control group, while the levels of the control group was same as that of the OP group. There was no significant difference between the HF and Q groups in bile acid/total lipid in feces. The amount of total cholesterol in liver increased significantly in HF group compared to the control group, while total cholesterol decreased significantly in the OP group compared to the HF group. There was a significant decrease in GOT (glutamic oxaloacetic transaminase) activity in OP and Q groups compared to the HF group. In conclusion, feeding onion powder to hyperlipidemic rates appeared to control weight gain, significantly lower the level of total cholesterol in the liver, and recover GOT activity. We also demonstrated that onion powder intake was more effective than quercetin intake.

  • In this study, various kind of onion herb kimchi differing in herb contents were prepared. Sensory evaluation indicated that rosemary was best of all for the tested herbs. By the sensory analysis, it seemed that 0.5% addition of fresh herb powder for onion kimchi was most preferable and 2% addition was not acceptable. Hot spice of onion was remained when kimchi was prepared but it disappeared as storage time elapsed. According to texture analysis, hardness decreased as storage time elapsed for onion kimchi without herb, but the degree was mitigated for onion herb kimchi.

  • This study was conducted to develop a topping formula for pizza containing Chungkukjang and onion as the main ingredients. The maximum amount of onion was limited to 10.5%, since the pizza crust and toppings would separate if too much water dispelled from the onion tissue during baking. The Chungkukjang was substituted for Bulgoggi, a meat topping. The sensory acceptability scores for the pizza topping decreased as the amount of Chungkukjang increased from 3.6% to 7.3%, due to its unpleasant odor, but scores increased when 1.6% Kimchi powder was added to the Chungkukjang without a significant difference from the control. Thus favorable sensory quality was obtained with a topping formula containing 8.7% Chungkukjang, 10.5% onion, and 1.6% Kimchi powder. The nutrient values of the final pizza products were assessed as follows. By adding the Chungkukjang and onion, crude protein, crude lipid, crude ash, and total dietary fiber contents increased. Moreover, the calorie level of the Chungkukjang-onion pizza was 3.8% higher than that of the control pizza. The amounts of compound amino acids including lysine increased. The free amino acids also increased from 143.3 to 188.6 mg/100 g. The ratio of saturated fatty acids to unsaturated fatty acids changed from 1:0.71 to 1:0.81. For the consumer test, the age groups of the participants were classified as 15-29 years old, 30-39 years old, and 40-62 years old. A positive result on acceptability of the developed pizza was obtained from most of the panelists in all age groups. Over 93% of the 119 responding subjects had purchasing intentions. An, especially, strong purchaging intention was shown in the younger age group of 15-29 year-olds, even though they had a lower preference for the Chungkukjang. Finally, an attribute of satisfaction was induced based on 'health' (79.5%) and 'flavor' (15.7%).

  • 본 연구에서는 강내한성 강원양파의 건조방법을 달리하여 건조방법에 따른 이화학적 특성을 비교하였다. FD, HD 40 및 HD 60의 세 가지 분말에 대해 일반성분 분석, 색도, 갈색도, 총 페놀 함량 및 DPPH free radical 소거능을 측정하였다. 일반성분 분석의 결과 FD의 조단백질 및 조지방의 함량이 각각 10.99%, 0.84%로 HD 40 및 HD 60 보다 유의적으로 높게 나타났다. 색도의 경우, Hunter's value로 L값(lightness), a값(redness), b값(yellowness)으로 나타내었다. FD의 L값이 $77.19{\pm}0.01$로 가장 높게 나왔으며, 나머지 a값 및 b값은 각각 $6.09{\pm}0.01$$6.09{\pm}0.01$으로 HD 60이 높게 나왔다. 갈변도의 경우에도 HD 60이 0.200으로 제일 높은 값으로 나타나 건조 온도가 높아질수록 양파의 갈변정도가 커진 다는 것으로 사료된다. 총 페놀 함량의 경우에 HD 40과 HD 60이 FD 보다 더 높은 함량을 나타내었다. DPPH radical 소거능은 시료의 농도를 0.1, 0.5, 1 mg/mL로 처리하여 측정한 결과 농도에 따라 유의적으로 항산화 활성이 증가되었으며, FD 보다 HD 40 및 HD 60에서 유의적으로 더 높은 항산화 활성을 나타내었다.

  • Drying process was applied to increase the antioxidant activity of onion powder: freeze-drying or air-drying at 50, 70, and $90^{\circ}C$ and onion extracts were obtained from each powder using water or aqueous ethanol (50%) at $25^{\circ}C$ and $60^{\circ}C$. In the color analysis, the freeze-dried powders showed higher $L^*$ and lower $a^*$ and $b^*$ values than did the air-dried ones. The browning index of powders air-dried at $90^{\circ}C$ was significantly higher than that of freeze-dried powders or those air-dried at temperatures below $90^{\circ}C$. Phenolic content in the extracts was 4.02-23.12 mg gallic acid equivalent/g sample, and was the highest in the extract from the sample air-dried at $90^{\circ}C$, regardless of the extraction condition. The highest antioxidant activity, measured by 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid and 1,1-diphenyl-2-picrylhydrazyl methods, was found in the powder air-dried at $90^{\circ}C$, which induced browning. These findings indicate that antioxidant activity depends more on browning during drying than on extraction conditions.

  • The purpose of this study was to test the overall preference of Saury fishmeat nuggets. In order to remove off-flavor of Saury and to improve the sensory properties of Saury fishmeat nuggets, different concentrations of vegetables (onion, 0-20%), different types of spices (ginger powder, white pepper powder, garlic powder) and different types of vegetables (onion & hot pepper, onion & pimento, mushroom & hot pepper, and mushroom & pimento) were added and the sensory properties were evaluated. Different types of herbs (Anthemis nobillis, Rosemarinus offcinalis L) and oriental herb (Angelica gigas Nakai, Acanthopanax sessiliflorus Seed) extracts were included as well to preserve the antioxidants in the nuggets after reheating. The main ingredients included saury mince, mild pizza cheese, hydrated textured soy protein, and egg white powder. The samples were molded (dia. 4.5 cm, thickness 1.5 cm, 20 g), lightly battered and fried for 2 min (2 time) at $160^{\circ}C$. The samples were then frozen, reheated ($150^{\circ}C$, 20 min) and subjected to a sensory evaluation. In the sensory evaluation, Saury nuggets made with a vegetable concentration of 15% had the highest flavor, taste, and overall preference (V5). In addition, Saury nuggets made with 1 g of ginger powder and garlic powder scored the highest in the preference test (S2). Saury nuggets made with onion and pepper had the highest score in the preference test relative to all the other tested vegetables (SV1). Finally, in terms of the herb and oriental herb extracts, the nuggets made with the condensed extracts at a 1/20 ratio of Acanthopanax sessiliflorus Seed (AS) scored the highest in the preference test, since AS had the lowest off-flavor taste.
