An experiment was carried out to evaluate the effects of substituted conjugated linoleic acid (CLA) for fat on qualities, lipid oxidation and residual nitrite contents in emulsion-type sausage (ETS) after different periods of storage. The control sausage contained 20% fat, however, the substituted CLA for fat sausages contained 17.5% fat+2.5% CLA, 15% fat+5% CLA, 12.5% fat+7.5% CLA and 10% fat+10% CLA, respectively. CLA concentration was significantly increased (p<0.05) by substitution of CLA sources for fat, and storage did not affect the CLA concentration. TBARS were significantly increased with the increasing of storage time in all treatments (p<0.05). Significantly higher $L^*$ values were observed in the 10% CLA treatment compared to other treatments during storage. Moreover, $a^*$ values in CLA treatments significantly (p<0.05) increased compared to the control. Again, $b^*$ values were significantly (p<0.05) higher in CLA treatments than those of the control during storage. The concentration of residual nitrite in ETS was significantly (p<0.05) different between the treatments during storage and the results were in the following order: control >2.5% CLA>5% CLA and 7.5% CLA>10% CLA. Overall acceptability of CLA treatments was significantly (p<0.05) lower than the control during storage, whereas no significant differences were found in overall acceptability between the treatments after 28 days of storage.

40 goat kid ribcages were held for 7 days in storage conditions ($4^{\circ}C$) and used to determine the effects of three different packaging methods (atmospheric air, vacuum and modified atmosphere package (MAP) 10:70:20 mixture of $N_2:O_2:CO_2$) on meat quality of the chops. L* was affected by the packaging method being lighter than MAP chops. The coordinate a* significantly increased during storage time. For MAP-packed chops and those kept in atmospheric air, b* increased markedly during storage time whereas it remained unaffected throughout storage when in vacuum packages. Final pH values ranged from 5.6 to 5.8 and no effects were found for either storage time or packaging method. WHC means were lowest for the three packaging methods on day 7 of storage and highest on day 1. Storage time increased water loss in vacuum treatments. Trained panel colour acceptability was lower at 3, 5 and 7 days than on day 1 of storage for atmospheric air treatment and vacuum packaging, while for the MAP treatment average values on days 5 and 7 were lower than those observed on days 1 or 3. Trained panel odour was lower for atmospheric air and vacuum packages at 3, 5, and 7 days storage than at 1 day, while no differences were found in trained panel odour acceptability for MAP packages. With reference to consumers, the MAP proposed in the present study is the chosen method for storing goat meat, rather than vacuum or atmospheric air packaging.

Background: Increasing uptake of human papillomavirus (HPV) vaccine should be a priority in developing countries since they suffer 88% of the world's cervical cancer burden. In many countries studies show that age at vaccination is an important determinate of parental acceptability. This study explores parental preferences on age-to-vaccinate for adolescent school-going girls. Materials and Methods: The sample was selected using a two-stage probability proportional to size cluster sampling methodology. Questionnaires were sent home with a random sample of 800 adolescent girls attending 12 schools in Mysore to be completed by parents. Descriptive statistics including frequencies, percentages and proportions were generated for independent variables and bivariate analyses (Chi square test) were used to assess the relationship between independent and appropriate age-to-vaccinate. Results: HPV vaccination acceptability was high at 71%. While 5.3% of parents felt girls should be vaccinated by 10 years or younger; 38.3% said 11-15 years; 14.8% said 16-18 years; 5.8% suggested over 19 years; and 33% didn't know. Only 2.8% of parents would not vaccinate their daughters. Conclusions: Delaying HPV vaccination until later ages may signifivantly increase uptake of the HPV vaccine in India.

The goal of this study was to develop new functional pear wine using six Asian pears (Pyrus pyrifolia, Nakai), namely Wonhwang, Niitaka, Whangkeumbae, Whasan, Gamcheonbae and Chuwhangbae. To select optimal yeast and pear, we investigated the physicochemical properties of the pear wines from fermentation of musts of six pear cultivars at $25^{\circ}C$ for 7 days by several yeasts. $11.2%{\sim}12.4%$ of ethanol from musts of 'Wonhwang', 'Whangkeumbae' and 'Whasan' were produced by Saccharomyces cerevisiae K-7 and 12.8% of ethanol was also produced from 'Niitaka' by commercial Saccharomyces cerevisiae C-2. 9.9% and 11.4% of ethanol were produced from musts of 'Gamcheonbae' and 'Chuwhangbae' by Saccharomyces cerevisiae KCTC 7904, respectively. Among several pear wines, Niitaka pear wine showed the best acceptability in the sensory evaluation, and Niitaka pear wine and Whangkeumbae pear wine showed 31.1% and 27.8% of antihypertensive angiotensin I-converting enzyme(ACE) inhibitory activity, respectively. However, the other functionalities were not detected or very low. Furthermore, Niitaka-strawberry mixed fermentation wine was showed the excellent acceptability and high antihypertensive ACE inhibitory activity of 64.9%.

The principal objective of this study was to evaluate the quality characteristics of pickled radishes (RP) containing gardenia fruits (RPG), beet (RPB), and spinach (RPS) juice. We have conducted the moisture, salinity, sweetness, pH, titable acidity, Hunter's color values, and mechanical characteristics with a sensory evaluation by elementary, middle, high and university students on the colored radish pickles. The moisture contents of RP, RPG, RPB and RPS are not significantly different. The salinity and pH of RP were significantly higher than that of RPG, RPB, RPS (p<0.05; p<0.01). The sugar contents of RPS are significantly higher than the of RP, RPG and RPB (p<0.001). The titrable acidity of RPB and RPS is significantly higher than that of the RP and RPG (p<0.001). The lightness (L) of RP, the redness (a) of RPB and the yellowness (b) of RPS are the highest in sample group. For changes in texture profile analysis, the hardness level of RPB is higher than that of RP, RPG and RPS (p<0.01), but the chewiness of RPG is higher than those of RP, RPB and RPS (p<0.001). In the sensory evaluation, RPB scores the highest in color, taste, and overall acceptability, whereas RPS scores the lowest in color and overall acceptability. Based on the above results, we expect that radish pickles with beet juice have good characteristics and acceptances within the school food services.

New in vitro anti-diabetes makgeolli was produced from rice by adding various quantities of Laminaria japonica, and the fermentation characteristics of the L. japonica makgeolli during the fermentation process were investigated. The contents of alcohol and reducing sugar, and viable count of yeast, of L. japonica makgeolli were not significantly changed when the proportion of L. japonica was increased. The total acid content decreased with an increase in L. japonica concentration; the pH and total bacterial cell count increased in proportion with the increase in L. japonica concentration. The L. japonica makgeolli contents of free sugars, such as fructose, glucose, and sucrose, and of organic acids, such as acetic acid, citric acid, succinic acid, and lactic acid, were altered during fermentation and showed various patterns. The effects of the quantity of L. japonica added on the acceptability and anti-diabetes activities of L. japonica makgeolli were also investigated. In a sensory evaluation, L. japonica makgeolli brewed by adding 2.5 or 5% L. japonica to the mash showed the best overall acceptability; the 12.5% L. japonica sample was least favored due to its seaweed flavor. L. japonica addition did not increase the peroxynitrite-scavenging activity of makgeolli. L. japonica makgeolli showed potent anti-diabetes activity, particularly that containing >7.5% L. japonica. Therefore, L. japonica makgeolli may represent a new functional makgeolli with anti-diabetes properties.
