식용 돼지췌장 리파제가 체다치즈에서 중성 휘발성 성분의 생산에 미치는 영향에 대하여 고찰하였다. 치즈 제조시 이 효소를 두 가지 함량으로 혼합하여 여러 온도에서 숙성시켰다. 2-butanone의 생산은 효소의 양과 숙성온도를 높였을 때 증가했으나, 2-pentanone의 생산은 숙성기간 중에 일관성이 없었다. Acetaldehyde는 aldehyde 중에서 가장 많이 생성되었고 일관성 있게 증가하였다. Alcohol 생산에서는 ethanol이 가장 높았지만 숙성 6주 후에는 일관성 있는 증가가 없었다. Ethylbutyrate는 ester중에서 가장 많이 생성되었고 리파제의 활성도와 숙성온도에 연관이 있었다. Dimethyl sulfide는 유일한 유황 성분이었지만 리파제의 첨가와 숙성온도에 영향이 없는 것으로 나타났다. 통계분석결과 치즈 숙성 중에 ethyl butyrate와 체다풍미가 유의성 있는 상호관계가 있었다.

Effects of commercial food grade porcine pancreatic lipase on the neutral volatile compounds in Cheddar cheese were studied The enzyme was incorporated into the cheese at two different levels of concentration and ripened at various temperatures. The production of 2-butanone increased at higher amount of lipase and higher temperature, but the production of 2-pentanone was inconsistent trends during ripening periods. The concentration of acetaldehyde was the highest among aldehydes and was increased consistently during ripening Periods. In alcohol production ethanol was the most abundant but no further consistent trend was observed after 6 wk. The production of ethyl butyrate was the most abundant ester and related io lipase activities as well as ripening temperatures. Dimethyl sulfide was the only sulfur compound and appeared not to be related to the addition of lipase or ripening temperatures . Statistical analysis suggested that ethyl butyrate was most correlated to aged Cheddar flavor during cheese ripening.
