2.1. Experimental design
The study was conducted in a 3 × 3 × 4 factorial experiment. Three
batches of goat milk ice creams were manufactured using three
different levels of low fat goat milk as skim (0.71% fat), 2% fat, and whole
milk (3.64% fat). The three levels of low fat goat milk ice creams were
manufactured and stored at −18 ◦C for four different storage periods as 0,
2, 4 and 8 weeks. The effects of two main factors and their interactions on
nutritional, textural, and sensory characteristics of the experimental goat
milk ice cream were evaluated. All experimental ice cream samples were
packaged in 227 g (8 ozoz) styrofoam cups until further analysis for basic
nutrient contents, lipolysis, textural and sensory characteristics.
