  • The ripening durations and ingredients for the Salchichon sausages were modified to increase pork rear leg consumption by Korean consumers. The salchichon, a ripened pork sausage, was produced to evaluate the efficacy of two different ripening durations with and without rosemary powder on salchichon sausage quality, and the treatments were: i) 45 days of ripening without rosemary, ii) 60 days of ripening without rosemary, iii) 45 days of ripening with 0.05% rosemary, and iv) 60 days of ripening with 0.05% rosemary. Significant differences were observed in both moisture and fat content for ripening durations, with the highest moisture and least fat content observed in salchichon modified sausage (SMS) ripened for 45 days. Ripening duration and rosemary addition appeared to influence water activity ($a_w$) of salchichon sausages. The $a_w$ of SMS ripened for 45 days was 0.80, whereas the other had $a_w$ values <0.80. Lactic acid bacteria were predominant, as Korean traditional fermented red pepper paste was added to sausages; however, the Bacillus cereus population was significantly affected by rosemary powder addition. Chewiness and gumminess decreased significantly due to the addition of rosemary powder compared to SMS without rosemary powder, and both 45 days of ripening and rosemary powder addition influenced the hardness of SMS. In conclusion, ripening duration of SMS for 45 days in the presence of rosemary powder provided superior SMS quality with an economical ripening duration compared to that of ripening with rosemary powder or ripening for 60 days.

  • The objective of this study was to evaluate the effect of dietary rosemary on performance, microflora population in cecum and noxious gas emission from litter of broiler. A total of 216 broiler chicks at 7 days old were fed the commercial diet (control), added 0.5% level of dried rosemary leaves (5 g/kg diet, T1) and 1.0% level of dried rosemary leaves (10 g/kg diet, T2) for 4 weeks. The body weight gain and feed conversion ratio were improved by feeding rosemary at 7 to 35 days of age (P<0.05), but there was no difference between T1 and T2. Amount of feed intake and mortality were not different among the three group. There was an increase in the microflora population of Lactobacillus (P<0.05) and decreased in E. coli and salmonella (P<0.05) in the cecum contents at 21 and 35 days of age. Emission of ammonia gas from litter was significantly decreased by supplementary rosemary at 21 to 35 days of age (P<0.05), but there was no difference between T1 and T2. These results indicated that feeding 0.5 to 1.0% level of dried rosemary leaves during broiler production improved in the body weight gain and feed conversion ratio because of increasing nutrient digestibility from feed, also increase in intestinal beneficial bacteria and decrease in harmful bacteria in the cecum contents, and decreasing emission of ammonia gas from litter.

  • Physicochemical qualities and consumer acceptability of chocolate layer cake were studied with varied levels of rosemary powder at 0, 0.2, 0.4 and 0.6%. The ash content of the cake increased from 2.30 to 3.10%, as the amount of rosemary powder increased from 0 to 0.6%, and the carbohydrate content of the cake decreased as the addition of rosemary powder increased. There were no significant differences in moisture contents and pH values among the samples and the pH values of all samples were within the typical pH range of 7.5-8.0 for chocolate layer cakes. Water loss from the control cake was greater than that from the cakes with rosemary powder supporting the suggestion that the addition of rosemary powder to the chocolate layer cake could increase moisture retention of the cake. Consumer acceptability of all the samples showed higher preferences of more than 7 points. Rosemary aroma, mint flavor and after taste were highly positively correlated with the fat content. Fat and ash content of the cake, which tended to increase in proportion to the rosemary powder content, were negatively correlated with acceptance of herb flavor, sweet taste, moistness, softness and intensity of softness but positively correlated with intensity of herb flavor. With the results above, trials on chocolate layer cake using rosemary powder were successfully performed within the ranges tested.

  • The purpose of our study was to determine the impact of rosemary extract in duck eggs, as determined by in vitro antioxidant capacity, lipid oxidation, fatty acid profiles, and flavor analyses. Three groups of salted duck eggs were compared: A control group and group enriched with 0.1% and 0.5% (w/v) rosemary extracts for 28 days of salting. In a time-dependent manner, the radical scavenging activity and reduction power of eggs with 0.5% (w/v) rosemary extract were significantly higher those of the control at 28 days after salting. The fatty acid profiles of salted egg were significantly affected by rosemary extract and salting time. Palmitic acid was the most abundant fatty acid in salted egg treated with rosemary extract, followed by linoleic acid and arachidonic acid. Furthermore, the treated eggs contained more docosahexaenoic acid than the control ones. And the treated eggs also have a considerable impact on the lipid oxidation process (primary and secondary oxidation). As a result, rosemary extract can be used as a natural antioxidant spice to prevent oxidation and extend the shelf life of eggs during storage. Furthermore, flavor research using solid phase microextraction - gas chromatography - mass spectrometry and an electronic nose demonstrated that adding rosemary extract to salted eggs could give them a distinct flavor.

  • Dyeing properties of rosemary colorants on wool fabrics were investigated. Reosemary colorants were characterized by UV and FT-IR analysis. Effect of dyeing condition on dye uptake and effect of mordanting on dye uptake, color change of colorfastness were explored. Rosemary colorants showed high affinity to wool fiber and its isotherm adsorption curve was Langmuir type. Therefore, it was considered that ionic bonding was involved in the adsorption of rosemary colorants to wool fiber. Rosemary colarants produced mainly yellowish color on wool fabric. The dyed wool fabrics showed generally high colorfastness except fastness to washing and light. Mordanting did not improve any colorfastness except that Sn mordant improved the light fastness. Bacterial reduction rate was increased up to 100% at 5% dye concentration. Therefore, antimicrobial activity of rosemary extract was confirmed.

  • Dyeing properties of rosemary colorants on cotton fabrics were investigated. Effect of dyeing conditions on dye uptake and effect of mordanting and cationizing on dye uptake, color change and colorfastness were explored. Also, antimicrobial activity of rosemary colorants was ascertained and further effect of cationizing on antimicrobial activity was investigated. Affinity of rosemary colorants to cotton fiber was considerably low, and its isotherm adsorption curve was Freundlich type, indicating that hydrogen bonding was involved in the adsorption of rosemary colorants to cotton fiber. The cotton fabrics showed generally high colorfastness except fastness to washing and light. The cationized cotton with Cationon UK(quarterly ammonium salt) showed higher dye uptake and shorter dyeing time, compared with the untreated cotton. The cationized cotton showed good colorfastness to washing, perspiration and rubbing. Antimicrobial activity of rosemary colorfastness was confirmed. The cationized cotton itself showed high bacterial reduction rate. For cationized and dyed samples, as dye uptake increased, bacterial reduction rate was decreased slightly.
