양파의 이용성 증대를 위해서 양파김치 분말을 첨가하여 풍미와 물리적 특성을 개선한 쌀 압출스낵의 제조조건에 따른 팽화물의 수분흡수율, 경도, 팽창률, 색도변화 및 관능검사 등의 품질특성을 조사하였다. 양파김치 분말 3~10%를 쌀가루에 첨가한 후 수분함량 20~26%로 조절하여 바렐온도 100~130℃, 스크루 속도 250 rpm에서 7 x 2 mm 압출구로 압출성형 한 다음 건조하여 양파김치 분말을 첨가한 쌀 압출팽화물을 제조하였다. 이들 중에서 양파김치 분말과 쌀가루 혼합물의 수분함량 24%, 바렐온도 130℃, 스크루 속도 250 rpm에서 제조한 압출성형물의 특성이 우수하였다. 쌀가루에 첨가한 양파김치 분말의 양이 증가할수록 압출물의 수분흡수율은 증가하였고, 경도와 팽창률은 감소하였으며 색차 △E 값은 증가하여 어두운 색깔을 보였다. 양파김치 분말 첨가량이 많은 10% 첨가구에서 수분흡수율은 가장 컸으나 경도는 가장 낮았다. 이같이 쌀 압출팽화물에 양파김치 분말을 첨가함으로써 팽화물의 물리적 특성을 개선하고 나아가 관능적 기호성을 향상시킬 수 있는 가능성을 보여 주었다.
Abstract
An extrusion process was used to make an onion kimchi snack from rice grit and onion kimchi powder, in an effort to enhance the nutritional value, flavor, and physicochemical properties of the extrudate. This study investigated optimum conditions (moisture content, barrel temperature, and the content of onion kimchi powder) for the production of high-quality rice extrudate products, and measured quality properties (water absorption index, texture, expansion ratio, and color) of rice extrudate to which onion kimchi powder had been added. Onion kimchi powder at 3%, 5%, 7%, and 10% (all w/w) was mixed with rice grit, and the mixture then extruded in a twin-screw extruder. The texture of onion kimchi snack became softer as onion kimchi powder level rose, and water absorption ability increased. The expansion ratio and the lightness of extrudates decreased with increases in onion kimchi powder levels. The maximum water absorption index and the minimum hardness were obtained with 10% onion kimchi powder. Rice extrudate with 10% onion kimchi powder was suitable for extrusion cooking and obtained the highest score for overall acceptability by sensory evaluation.
