[求助] 乳化活性EAI计算公式已有1人参与

EAI=4.606×A×dilution factor/(C×F×10000),请问这个公式里的dilution factor是怎么算的,是蛋白溶液的稀释倍数吗还是要加上油的体积?

dilution factor是整个乳液体系的稀释倍数,如下陈述:
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.
因此此时的稀释倍速应该是500
