For the pork flavors, PH10YE gave the best
sensory evaluation score, although this was not
significantly different from those of PH-R and
PH20YE. Thus, any of the three tested methods for
these would be suitable for preparing a good flavor.
The yeast extract studied was prepared from low cost
spent brewery yeast. Thus, the higher the quantity
of yeast extract that could be used to replace meat,
the lower would be the production cost of the flavor.
Thus, in the case of pork flavor, more yeast extract
could be used (up to 20% w/w) than that used to
prepare beef flavor (ie, 10% in BH10YE was best)
without obtaining too strong a yeast extract odor.
