Based on the sensory analysis results, especially those for
texture, two samples were selected for further analysis (T5 and T8).
As seen in Table 4, the higher the WPC (up to 40 g WPC/100 g) and
margarine (up to 33.4 g margarine/100 g) contents, the higher the
moisture content. According to Chung, Cho, and Lim (2014), cookie
moisture should be between 2 and 8 g/100 g. Therefore, by this
recommendation, the cookies made with WPC are suitable. Treatment
8 (40 g WPC/100 g and 33.4 g margarine/100 g) exhibited a
higher protein content (45.2 g/100 g), with four times the protein
content of the cookies made with whey protein by Sarabhai and
Prabhasankar (2015). Based on a serving size of 30 g, treatments
8 and 5 can be classified as having a high protein content (WHO,
2007, p. 41), with 13 and 11 g of protein per serving, respectively.
This designation does not apply to the control treatment (6 g of
protein per serving).
