The quality of fried batter of Tempura (Koromo) was studied by sensory evaluation and moisture measurement using eight different oils (safflower, grapeseed, sunflower, cottonseed, corn, soybean, sesame and rapeseed oils) and then the effect of sesame oil added to soybean oil was investigated. Batters were prepared with 50g of distilled water and 25g of flour and fried into flakes in 400g oil at 175°C.
The three samples fried in safflower, grapeseed and sunflower oils were judged organoleptically to be worse than those fried in the other five oils. The sample fried in sesame oil was evaluated to have the best flavor. It was found by multiple regression analysis that the taste and mouthf eel of the samples fried in the four oils, safflower, grapeseed, sunflower and cottonseed oils contributed more strongly to the total acceptance than the flavor. All the flavor, taste and mouthfeel of the sample fried in sesame oil was found also to contribute to the total acceptance.
Two mixtures of 30 and 50% sesame oil and soybean oil contributed more strongly than a mixture of 0,10, and 100% to the quality of the fried batter. lt was found by multiple regression analysis that the taste of the sample fried in 30% of sesame oil mixture contributed to the total acceptance, and all the flavor, taste and mouthf eel of the samples fried in 50 and 100% sesame oil mixture contributed to the total acceptance. Negative higher correlation was obtained between the moisture content and the value of mouthfeel than between the moisture content and the flavor, and also between the moisture content and taste.
From these results, we conclude that addition of sesame oil of 30-50% in sesame oil/soybean oil mixture improves the quality of fried batter of Tempura (Koromo).
