The percentage weight loss from the cooking of satay samples
varied among treatment of local spices as shown in Table 4. The
percentage weight loss during cooking increased with degree of
doneness. The percentage weight loss for satay samples treated
with local spices was significantly (p < 0.05) different. This is
probably due to water loss during grilling. The weight loss of present
study is comparable to previous study conducted by Jinap et al.
(2013), in which they have observed that the percentage weight
loss during cooking increased with degree of doneness for chicken
(21.0 ± 0.25 to 33.2 ± 0.65 g/100 g) and beef (25.4 ± 0.35 to
39.3 ± 0.31 g/100 g). The weight loss during cooking is probably due
to the loss of water suggested by Skog and Solyakov (2002). In their
study, they observed that pre-treatment with microwaves before
cooking has reduced the formation of heterocyclic amines owing to
the loss of precursors by leakage. Felton, Fultz, Dolbeare, and Knize
(1994), reported that microwave pre-treatment for 0e3 min before
frying at either 200 C or 250 C for 6 min per side of Hamburger
patties reduced heterocyclic aromatic amine precursors (creatine,
creatinine, amino acids, glucose), water, and fat by up to 30 g/100 g.
