Hydrocolloids로 arabic gum, carboxymethylcellulose, pectin 등을 밀가루 대비 각각 0.2와 0.5% 첨가하여 제조한 par baked 바게트를 냉동저장(-18oC)하면서 1주일 간격으로 해동 후 구워 비용적, 수분함량, 경도 및 관능검사 등을 분석하였다. 비용적은 3주 저장 시 CMC을 0.2% 첨가한 것이 3.20 cc/g로 가장 높았고, 수분함량은 대조구와 시험구간에 변화가 거의 없었으며, 경도는 3주 저장 시 pectin을 0.2% 첨가한 것이 가장 낮아 부드러운 것으로 나타났다. 관능검사에서 저장 3주에 pectin을 0.2% 첨가한 것의 전체적인 기호도가 가장 높은 점수를 얻었다. 이상의 연구에서 par baked바게트를 냉동저장 시 pectin을 0.2% 첨가한 제품의 특성이 가장 좋은 것으로 나타났다.
This study was carried out to evaluate the effects of hydrocolloids such as arabic gum, carboxymethylcellulose (CMC), and pectin on the quality and sensory properties of frozen-par baked baguettes according to frozen storage periods. Exactly 0.2 and 0.5% hydrocolloids were added to the baguettes based on flour. Specific loaf volume, hardness, moisture content, and sensory evaluation of baguettes were analyzed. Specific loaf volume of baguette with added 0.2% CMC was the highest after 3 weeks of storage at $-18^{circ}C$. Moisture contents were not significantly different between control and experimental baguettes. In terms of hardness, baguette with added 0.2% pectin had the lowest value after 3 weeks of storage at $-18^{circ}C$. In sensory evaluation, baguette with 0.2% pectin among hydrocolloids had the highest score for external and internal properties, as well as total acceptance. Consequently, 0.2% pectin increased the quality of baguette.
