이 총설의 목적은 도포 숙성 치즈와 곰팡이 숙성 치즈의 제조 공정의 차이를 살펴보고 이들의 관능적 특성 차이에 관하여 비교 분석 하는 것이다. 도포 숙성 치즈와 곰팡이 숙성 치즈의 관능적 특성은 치즈의 품질 평가에서 가장 중요한 요소이다. 도포 숙성 치즈는 부드럽고 잘 부스러지는 질감을 가지고 있다. 그리고 블루 치즈와 비교하여 짠맛과 신맛이 강한 편이다. 반면에 블루 치즈 (곰팡이 숙성 치즈)는 산양유로 만들었을 때 더 부드럽고 크림과 같은 질감이 나며 냄새가 좀 더 강한 편이다. 블루 치즈는 좀더 산도와 짠맛, 쓴맛이 도포 숙성 치즈에 배하여 강한 편이며 좀 더 신선한 맛이 나는 것이 특징이다. 또한 도포 숙성 치즈와 곰팡이 숙성 치즈의 관능적 특성, 예를 들면 냄새, 맛, 질감 등은 치즈의 품질 평가에 아주 중요한 요소로 작용할 것이라 사료된다.

Objective: This study aimed to evaluate the effect of dietary integration with extruded linseed (EL) on fatty acid (FA) and aromatic profile of goat cheese after 60 (T₆₀) days of ripening. Methods: Thirty goats were divided in two groups. The control group (CG) was fed with conventional diet, whereas the experimental group (EL+) was fed with conventional diet supplemented with 10% of EL. Milk samples were collected on 30 and 60 days of trial to determinate chemical-nutritional composition and FA profile. At the end of experiment, six cheese-making sessions (3 for each group) were carried out using a pooled milk sample obtained from the 15 goats of each group. At 60 days of ripening, cheeses were analyzed for chemical-nutritional composition, FA and aromatic profile. Results: An increase in the milk production, protein, fat and lactose were evidenced in the EL+ goats. Conversely, a reduction of somatic cells was observed in the EL+ compared with the CG. However, no variation was observed for urea and casein levels content in milk samples, and no changes in protein and lipid content were found for cheeses in the two experimental groups. Dietary supplementation with EL modified the FA profile of milk. There was a decrease in saturated FAs and an increase in polyunsaturated FAs. Chemical composition of T₆₀ cheese did not differ between the two groups but a different FA profile was observed. In T₆₀ cheese obtained from EL+ milk, an increase in short-chain FA and a decrease in medium and long-chain FA were observed. The EL diet led to cheeses with butanoic acid 2 times higher compared to CG cheeses. Moreover, a greater presence of aldehyde compounds and alcohols were observed in the cheeses of experimental group. Conclusion: The present study pointed out that EL supplementation may improve the chemical and physical qualities of goat milk and cheeses.
