비동결 파운드 케이크의 배합비를 반응표면분석법에 의해 여러 가지 동결방지제의 함량을 조절하여 결정하였다. 수분함량만이 동결방지제 함량과 선형관계를 나타내었으나, 다른 반응변수들은 quadratic모형으로 나타났다. 비동결 파운드 케이크에 제조시 함유되는 당류의 최적 배합비는 7736 : 0.0 : 20.4, 60.0 : 32.8 : 16.4, 70.8 : 11.2 : 19.6와 같이 3가지로 제시되었다. 최적배합비로 제조한 파운드 케이크의 냉동
The optimal formula for non-frozen pound cake was sought using a central composite design with a quadratic model, by response surface methodology (RSM). Behavior on supercooling, freezing time, theological properties, and sensory attributes of pound cake were studied by using various concentrations of sugar, sorbitol, and glycerol. The freezing temperature of standard pound cake was . The hardness, freezing point temperature, and sensory properties were shown as a quadratic relationship whereas moisture content was analyzed by a linear model. Optimized formula for non-frozen cake were suggested to include (sugar:sorbitol:glycerol) 77.6:0.0:20.4, 60.0:32.8:16.4, and 70.8:11.2:19.6 (all % of total sugar) by RSM. The freezing tines of optimized non-frozen pound cake were reduced by . The freezing Points of optimized pound cake were depressed below . Sorbitol and glycerol may be used as cryoprotectants and preserve the desired sensory attributes of pound cake at low temperatures.
