  • The anti-obesity effects of yeast hydrolysate (YH) supplementation (1.0 g/d) have already been demonstrated. We investigated whether a low dose of YH (0.5 g/d, YH-500) also has the anti-obesity effects. Thirty obese women were randomly assigned to the control or YH-500 groups. After 8 weeks, weight and body mass index were significantly reduced by the YH treatment (0.5 g/d) (P<0.05). The YH-500 group lost a significant amount of body fat after the 8-week treatment: fat mass 25.9 kg (baseline) versus 23.8 kg (8th week), P<0.01; fat mass ratio 38.8% (baseline) versus 36.5% (8th week), P<0.05. The YH-500 group showed a significant reduction in calorie intake during the 8-week treatment (P<0.001). The control group wanted to eat much more food (P<0.05) and sometimes thought about eating more often compared with the YH-500 group (P<0.05). Whereas the control group showed a slightly increased sweet preference, the YH-500 group showed a significant reduction in sweet preference (P<0.05). In conclusion, low dose YH supplementation (0.5 g/d) may induce a reductions in weight and body fat in obese women via the reduction of calorie intake.

  • Product quality and shelf-life effect of sodium lactate (SL) in combined with chitosans with various molecular weights (MW) in low-fat sausages (LFSs) stored at $10^{\circ}C$ were evaluated. LFSs with SL and chitosans had 75-76% moisture, 1-2% fat, and 15.8-17.1% protein with a pH range of 6.3-6.6. Water holding capacity was decreased, but most textural properties were increased with the addition of chitosan with MW of 30-40 kDa. Hunter a (redness) values were also increased with the addition of sodium lactate and chitosans in combination with laccaic acid at the level of 0.05%, resulting in similar Hunter a value of 150 ppm of sodium nitrite. The combination of SL and chitosans slightly extended the shelf-life of LFSs approximately 3-6 days at $10^{\circ}C$, resulting in inhibition the growth of L. monocytogenes and E. coli O157:H7, as compared to the control. However, the inhibition of microbial growth at $10^{\circ}C$ was not as strong as that at $4^{\circ}C$. Thus, the storage temperature should be as low ($<4^{\circ}C$) as possible to have a maximum antimicrobial activity in LFS containing SL and various chitosans.

  • Objective : The purpose of this study is to evaluate the effect of Yuebijiashu-tang with Low-Glycemic Diet on the obesity and to improve the oriental medical methods of treatment in obesity patients. Methods : Forty one patients were classified into four groups(Normal, Overweight, 1st Obesity, 2nd Obesity) by Body Mass Index(BMI). Weight, Body Fat Mass, Body Fat Rate, Waist Hip Rate, BMI and Obesity Index were compared in each group by t-test. Results : In distribution of sex, male was 7(17.1%), female was 34(82.9%). Mean age was 37${\pm}$11 and the patients in twenties were the most. Among four groups, the number of 1st obesity groups was the most. In the change of body composition, the reduction of weight was 6.82${\pm}$2.67kg, the reduction of body fat mass was 5.53${\pm}$2.30kg, the reduction of BMI was $2.51{\pm}0.85kg/m^2$, the reduction of body fat rate was 4.61${\pm}$2.17%, the reduction of waist hip rate was 0.019${\pm}$0.013. Conclusion : This study shows that Yu$\'{e}$biji$\~{a}$sh$\`{u}$-t$\~{a}$ng with low-glycemic diet is effective on weight reduction.

  • The sodium amuounts of 35 food items and of the city supplied tap water in Seoul area were analyzed ay the Atomic Absorption Spectrophotometry. The Korean food exchange lists for the sodium resricted diets were developed from the available data and the ones newly obtained in this research. The food exchange lists provided in this research is compiled from (1) Milk group (2) Vegetable groups : A with the carbhydrate content of 0-4.9% and -B with that of 5.0-14.9% (3) Fruit group (4 ) Grains and starch food group (5) Meat groups : -Low fat meat and protein foods with the fat content of 0-3.0gm ; -Medium fat meat and protein foods with that of 5.0gm and : -High fat meat and protein foods with that of 8.0gm and (6) Fat group. Lists of sweets, alcoholic and nonalcoholic beverages and seasonings and condiments were also provided with the amount of sodium they contain in portions commonly used. The research described in this report was supported by the Grant from the Department of Education.

  • We manufactured the sausages replaced part (8%) of the pork fat (20.8%) with pepper seed powder (1%) and pepper seed oil (7%). The treatment of pepper seed did not affect pH and microbial quality, but decreased TBARS and VBN of sausages. Although the addition of pepper seed hardly changed textural properties of sausages except for increasing cohesiveness, it enhanced sensory characteristics such as taste, appearance, and overall acceptability. As expected, significant reductions were observed in the content of calorie, total fat, saturated fat, and sodium by replacing pork fat with pepper seed oil and pepper seed powder in sausages. Therefore, pepper seed is good enough to improve the sensory and nutritional quality of sausages.

  • The aim of this study was to develop muffins with whey protein concentrate (WPC) substituted for fat at the content of 10%, 20%, 40% or 80%. The quality characteristics were compared with those of a full-fat counterpart. With increasing WPC content, moisture, protein, and ash contents increased, fat content decreased, volume and specific volume of muffin decreased, but weight was unaffected. Crust lightness and yellowness of muffins increased, but redness decreased with increasing amount of WPC. Hardness, cohesiveness, springiness, gumminess and brittleness were the highest in muffin substituted with 80% WPC. Results of sensory evaluation indicated that muffin with up to 40% of the butter substituted by WPC was considered to be as acceptable as the control muffin prepared without WPC.

  • This study was conducted to find out the effect of fermented milk on lowering of serum and liver cholesterol in high diet. Sprague-Dawley male rats of 200g initial average weight were assigned to four experimental group : (1) high fat diet + milk (2) high fat diet + bifidobacteria (3) high fat diet + microcapsulated bifidobacteria (4) high fat diet + fermented milk by bifidobacteria. Milk, bifidobacteria, microcapsulated bifidobacteria and fermented milk by bifidobacteria were given 2ml per day. According to the result, there was lowering effect of serum and liver total cholesterol in fermented milk feeding group, Serum LDL-cholesterol was also low tendency in fermented milk by bifidobacteria feeding group. Accordingly, it was confirmed that the material that caused hypocholesteremic effect was not the bifidobacteria itself in fermented milk but the metabolic material produced in the fermentation, and it inhibited cholesterol synthesis in liver.

  • Pork is known as one of the preferred part of meat worldwide. Especially, the belly, known as 'Samgyeopsal' in South Korea, has been preferred by consumers in South Korea. Pork belly contained various component muscles, intermuscular and subcutaneous fat. The high-fat belly cut (containing 50%-60% fat ratio) has a low preference in South Korea whereas, the standard belly cut (20%-40% fat ratio) of the consumer preference was different. In addition, the evaluation system focused on lean meat production, represented by loin eye area and back fat thickness. In this review, we discussed the pork belly structure, phenotypic correlation with lean meat production ability and meat quality, and genetic potential to confirm to possibility of application to pig breeding. Moreover, the confirmed possibilities considered that could be a base on the evaluation of standard for the pork belly as an economic trait.
