VITAMIN A FORTIFIed PEANUT BUTTER - The Official Website of ...

Trials at the Industry Collaborator’s Plant
Fortified peanut butter was prepared at the industry collaborator’s plant following the same twostep
fortification process used in the laboratory trials at FDC with modifications on the mixing procedure
and type of equipment used.
In the premix preparation, the modification consisted of the continuous mixing of the fortificantplain
peanut butter mixture for 10 min. The Hobart planetary mixer and the locally fabricated horizontal
mixer of the industry collaborator were used for mixing. For the preparation of the final fortified product,
the same mixing procedure as above was followed to mix the premix with plain peanut butter mixture.
The same horizontal mixer of the industry collaborator was used for mixing. The schematic diagrams of
the procedure for the preparation of premix and fortified peanut butter are shown in Figures 2.6 and 2.7,
respectively.
Pre-heat vitamin A palmitate in a water bath
maintained at 40 o C for 15 min
Weigh required amount of vitamin A palmitate
and plain peanut butter in separate containers
Add pre-weighed vitamin A palmitate to the
center of pre-weighed plain peanut butter
Manually mix vitamin A palmitate to plain peanut butter
with a plastic spatula until no trace of the fortificant is
visible from the surface of the peanut butter mixture
Transfer the mixture of vitamin A palmitate
and plain peanut butter to a mixer
Mix for 10 min
Manually fill the premix in plastic containers
Seal containers and store in a cool dark place
