All three types of the experimental low-fat soft-serve
goat milk ice creams showed substantial increases in
textural properties especially in firmness and consistency
after 8 weeks frozen-storage. High variations in
elevation of the textural characteristics of the frozenstored
ice cream samples appeared to be attributed to
the hardening of the products during the frozen-storage,
as well as the difference in sensitivity of the texture
analyzer between soft serve and hardened ice cream samples.
The flavors of the low-fat goat ice creams were signifi-
cantly influenced by storage period in cooked, sweetness,
freshness, rancidity, whey and oxidized flavors, but not in
acid flavor. Among body and texture properties, sogginess
and fluffiness were the only two properties affected by the
storage periods. Although there was a slight decrease in
overall acceptability ofthe three experimental low-fat goat
ice creams during 8 weeks storage, textural and sensory
qualities of the three types of low-fat goat milk ice creams
were acceptable.
Even though the commercial ice cream pre-mix contains
minor ingredient (sodium caseinate) derived from
cow milk, their effects were expected to be identical and
equally canceled out from all three different goat milkbased
experimental ice creams, whereby the comparison of
textural and sensory qualities between the products would
be valid. However, further studies may be necessary to
determine textural and sensory qualities using the premix
containing only goat milk ingredients, when it becomes
available.
