The highest mean overrun percentage was determined in the ice cream sample containing 1.0% WGOE, followed by that containing 0.5% WGOE and control sample, but the differences among them were not significant statistically (p>0.05). It is usually made from dairy products, such as skimmed milk powder or butter, often combined with sucrose, stabilisers, emulsifiers, colourings and flavourings (Shanmugam & Marimuthu, 2017), and assembled in a solid foam, which is made by the dispersion of gas bubbles in a solid continuous phase (Rizzo, 2016). = (82 - 40)/40 x 100% = 105%, (Note : The pecans do not incorporate air.

A non-dairy product often referred to as water ice and is a blend of corn syrup, fruit, and citrus juice. Other machines use peristaltic tube which don't need to be lubricated & have less parts, which makes it easier to clean.
