Abstract

The quality of commercial milk was evaluated by sensory testing. The results were summarized as follows; 1. A significant difference on the quality and preference was not recognized at 5 percent level among the sample of commercial milk produced by five companies according to the result of rank test for commercial milk. 2. According to a scoring test for determination of shelf life of commercial milk A, the sensory quality of the sample milk was maintained for three days at $0^{\circ}C$ to $5^{\circ}C$ and $10^{\circ}C$ for one day at $20^{\circ}C$ and $30^{\circ}C$. 3. According to the result of profile test for commercial dried milk C, dilution number was 20.0 and sensory quality of the dried milk was comparatively satisfactory. 4. According to the result of profile test for commercial milk, the synthetics flavor of each milk was generally evaluated as excellent and the intensity of flavor was somewhat different among the samples of commercial milk produced by five companies. 5. A significant difference on the flavor of milk was recognized among five sample of commercial milk by both difference test and profile test but not recognized by rank test.

시판(市販) 우유 및 분유를 시료(試料)로 하여 관능(官能) 검사법(檢査法)에 의한 품질(品質) 평가(評價)를 실시하여 다음과 같은 결과(結果)를 얻었다. 1. 시판(市販) 우유에 대한 순위(順位) 시험(試驗) 결과(結果), 5개(個) 회사(會社) 제품별(製品別) 시료(試料)의 품질(品質) 및 기호도(嗜好度)에 있어서 5% 수준(水準)에서 유의적(有意的)인 차이(差異)가 인정(認定)되지 않았다. 2. 채점(採點) 시험(試驗)에 의한 시판(市販) A우유의 shelf life 검사(檢査) 결과(結果), $0{\sim}5^{\circ}C$$10^{\circ}C$에서는 3일간(日間), $20^{\circ}C$, $30^{\circ}C$에서는 1일(日) 정도 품질(品質)이 유지되었다. 3. 시판(市販) C분유(粉乳)에 대한 희석(稀釋) 검사(檢査) 결과(結果), 희석(稀釋) 계수(係數)가 20.0으로 시료(試料) 분유(粉乳)의 품질(品質)은 비교적 양호(良好)하였다. 4. 시판(市販) 우유에 대한 풍미(風味) 묘사(描寫) 시험(試驗) 결과(結果), 각 우유의 풍미(風味)는 종합적으로 우수하게 평가(評價)되었으며, 구성(構成) 풍미(風味)의 강도(强度)는 회사(會社) 제품(製品) 별(別)로 다소(多少)의 차이(差異)를 나태내었다. 5. 시판(市販) 5개(個) 회사(會社) 제품(製品) 별(別) 우유의 풍미(風味)에 대한 차이(差異) 식별(識別) 시험(試驗)이나 묘사(描寫) 시험(試驗)에서는 뚜렷한 차이(差異)를 나타내었으나 순위(順位) 시험(試驗)에서는 유의적(有意的)인 차이(差異)가 인정(認定)되지 않았다.
