Abstract

Effects of mashed wax gourd (Benincasa hispida) on texture and sensory quality of bread were evaluated. Farinograph results revealed increase in mechanical tolerance index (MTI) and water absorption, and decrease in dough stability with the addition of wax gourd. Addition of wax gourd also decreased loaf weight and volume. L, a, and b values of crust decreased with increasing addition of wax gourd, Whereas no effect on the color of crumb, Firmness of bread crumb increased with the addition of wax gourd at 67%, resulting in significant increase in hardness, gumminess, and chewiness of bread. Sensory evaluation revealed that acceptable quality of bread could be obtained by the addition of wax gourd up to 50%.

동아식빵 제조를 위해 동아를 $10{\sim}67%$까지 첨가하고 farinogram에 의한 반죽 특성을 조사한 결과 동아 첨가량이 증가할수록 반죽의 안정도가 감소하고 MTI가 증가하여 밀가루의 안정성은 감소하였다. Baking 후 빵의 부피는 대조구에 비하여 $3.1{\sim}6.4%$ 감소하였으나 중량은 유의적인 차이를 보이지 않았다. 빵의 crust의 색도는 L, a, b값 모두 동아 첨가량이 증가함에 따라 완만하게 감소하였으며 67% 첨가했을 때 가장 낮았다. Crumb의 색도는 동아 첨가에 의한 영향을 받지 않아 모든 처리에서 유의적인 차이를 보이지 않았다. 동아 첨가 빵의 texture를 측정한 결과 동아 첨가량 50%까지는 texture에 큰 영향을 주지 않았으며 67% 첨가했을 때 경도, 검성, 씹힘성에 있어서 유의적인 증가를 보였다. 동아를 첨가한 빵의 관능검사 결과 동아 첨가량 50%까지는 대조구와 유의적인 차이를 나타내지 않았다. 따라서 식빵 제조에 있어서 동아 적정 첨가량은 50%로 나타났다.
