乳化活性EAI計算公式 已有1人參與

EAI=4.606×A×dilution factor/(C×F×10000),請問這個公式里的dilution factor是怎么算的,是蛋白溶液的稀釋倍數(shù)嗎還是要加上油的體積? @lovibond 發(fā)自小木蟲Android客戶端 |

dilution factor是整個乳液體系的稀釋倍數(shù),如下陳述: The EAI and ESI values of emulsifiers were determined following a method described elsewhere (Pearce and Kinsella, 1978, Tan et al., 2014). Emulsion (100 μL) was prepared using the method described in section 2.8.1 with the emulsifier to oil ratio at 2:1. The emulsion was diluted 500 times with sodium dodecyl sulfate solution (0.1%, w/w), and measured by a UV–Vis spectrophotometer at 500 nm. 因此此時的稀釋倍速應(yīng)該是500 參考文獻(xiàn): Effect of pH and ionic strength on the emulsifying properties of two Octenylsuccinate starches in comparison with gum Arabic |
