The objective of this study was to determine the physicochemical and sensory properties of Appenzeller cheese supplemented with different concentrations (0, 1, 2, 3, and 4%, w/w) of powdered microcapsules of tomato extracts (PMT) during ripening at 14℃ for 6 mon. The particle sizes of PMT ranged from 1 to 10 m diameter with an average particle size of approximately 2 m. Butyric acid (C₄) concentrations of PMT-added Appenzeller cheese were significantly higher than that of the control. Lactic acid bacteria counts in the cheese were not significantly influenced by ripening time from 0 to 6 mon or the concentrations (0-4%, w/w) of PMT. In terms of texture, the hardness of PMT-added Appenzeller cheese was significantly increased compared to the control. The gumminess and chewiness of PMT-added Appenzeller cheese were similar to those of the control. However, both cohesiveness and springiness of PMT-added Appenzeller cheese were slightly decreased. In sensory analysis, bitterness and sourness of Appenzeller cheese were not significantly changed after supplementation of PMT, but sweetness of the cheese was significantly increased after increasing the ripening time from 0 to 6 mon and increasing the concentration from 1 to 4% (w/w). Based on these results, the addition of the concentrations (1-4%, w/w) of PMT to Appenzeller cheese can be used to develop functional Appenzeller cheese.

The effects of adding shrimp (Periclimenes imperator) powder to Appenzeller cheese on quality and characteristics during ripening were investigated. Cheese samples were prepared containing 1.0%, 2.0%, and 3.0% shrimp powder. Changes in the lactic acid bacterial populations, pH, water-soluble nitrogen concentrations, consumer acceptability, colour and texture were monitored during ripening. The addition of shrimp powder did not affect the appearance or consumer sensory characteristics of the cheeses. Likewise, cheese cohesiveness, fracturability, and springiness were not significantly altered. It was concluded that the quality of the Appenzeller cheese was not affected by adding shrimp powder.

The effects of adding fish surimi to Appenzeller cheese on quality characteristics during ripening were investigated. Cheese samples were prepared with 1.0% surimi. Changes in chemical composition, lactic acid bacterial population, pH, non-casein nitrogen, non-protein nitrogen, water-soluble nitrogen, a consumer sensory evaluation test, chromaticity, texture, and proteolysis were monitored during ripening. The electrophoretic patterns of cheese proteins and the functional components originating from the surimi were investigated. Adding surimi did not affect the appearance or consumer sensory characteristics of the cheeses. Significantly higher amounts of crude fat and moisture were observed in the cheese supplemented with surimi than in cheese without added surimi.

Effects of Chlorella powder on the growth of lactic acid bacteria, ripening velocity and organoleptic properties in Appenzeller cheese were investigated. Added levels of Chlorella powder were 0, 0.5, 1.0 and 2.0%. The lactic acid bacteria count was higher in cheese added with Chlorella than those in the control cheese. The pH of cheese increased gradually after 3 weeks, reaching pH $5.4{\sim}6.2$ at 15 weeks of maturation, and the pH was slightly lower in Chlorella added cheese than in control cheese. The soluble nitrogen compounds, non casein nitrogen (NCN) and non protein nitrogen (NPN), in Appenzeller cheese increased during 15 weeks of ripening, and they were higher in Chlorella added cheese than in control cheese. Electrophoresis of cheese proteins revealed that caseins were degraded more rapidly in Chlorella cheese as the level of Chlorella increased so that the cheese with 2% Chlorella could have developed a bitter taste and a stench by an excessive degradation of proteins. Sensory scores of the cheese ripened for 15 weeks were diminished as the level of Chlorella increased especially the cheese added with 2% Chlorella obtained significantly lower values of sensory scores than control cheese. Among the Chlorella cheeses, 0.5% Chlorella added cheese showed the highest score in overall sensory preference. From the results, the adequate level of Chlorella powder being added to produce an Appenzeller cheese product with acceptable quality was suggested to be 0.5%.

This study was performed to develop a Korean natural cheese with traditional medical wine, making it different from foreign natural cheese. The effects of cheese with Sasam(Codonopsis lanceolate) wine(CLW) on the quality properties during the ripening period of natural cheese were investigated. The properties investigated were growth of lactic acid bacteria, characteristics of ripening, and sensory characteristics. Four vats of cheese were made on the same day from the same tank of fresh milk. Cheese samples were prepared with CLW at 2.0%, 4.0% and 6.0% of raw milk. Changes in gross composition, viable cell counts, pH, water soluble nitrogen(WSN), non casein nitrogen(NCN), non protein nitrogen(NPN), and proteolysis during maturation were measured. Polyacrylamide gel electrophoresis(PAGE) patterns were determined with control cheese. Viable cell counts of control and CLW cheese were not significantly different. The pH of CLW cheese increased gradually during maturation, and saponin levels and levels of NPN, NCN, and WSN were higher in CLW cheeses than control cheese. For most compositional data, the 4.0% CLW cheese was most similar to the control cheese. The PAGE pattern of cheese caseins indicated that the CLW cheeses degraded more rapidly than the control cheese. Control and 2.0% CLW cheese had good sensory scores, while scores for 4.0% and 6.0% CLW cheese were lower. However, sensory data depreciated with added levels of CLW, especially at a level of 4.0% or more. Further studies on levels of CLW and processing methods are required to improve sensory quality.

Appenzeller cheese samples were prepared by addition of 0.5, 1.0, and 2.0% green tea (Camellia sinensis, CS) powder and control cheese. We examined various quality characteristics of the novel cheese, such as viable-cell counts, pH, water-soluble nitrogen (WSN), non-casein nitrogen (NCN), non-protein nitrogen (NPN), and catechin level during maturation for 16 weeks at $14^{\circ}C$. To develop a Korean natural cheese containing green tea powder, we also analyzed the changes in the polyacrylamide gel electrophoresis pattern, chemical composition, and sensory qualities. The viable cell counts of the samples were not significantly different. Until the $3^{rd}$ week, the pH of the CS cheese decreased with an increase in the maturation time. However, the pH gradually increased by the $12^{th}$ week, while WSN, NCN, NPN also increased. The WSN, NCN, NPN, and catechin values for the CS cheese samples were significantly higher than the values for the control cheese. The polyacrylamide gel electrophoretic pattern of caseins for the CS cheese indicated that this cheese degraded more rapidly than the control cheese did. In the sensory evaluation, cheese with 1.0% CS powder showed the highest scores in taste and appearance and good scores in flavor and texture. These results indicate that 1.0% CS is the optimal value for addition to cheese, and cheese containing 1.0% CS shows good physiological properties and reasonably high overall sensory acceptability.
