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

premix to plain peanut butter proportion of ∼1:50. At this weight ratio, the final product was calculated to
have a vitamin A content that meets at least one third of the RENI. The dyed peanut butter-plain peanut
butter mixture was then transferred to a Hobart vertical mixer Model HCM 300 (Hobart Corporation,
Troy, Ohio, U.S.A.) and mixed for a total of 10 min, stopping every 5 min interval to allow retrieval of
adhering peanut butter that splattered at the sides of the mixer. The schematic diagram of the dye test
procedure for the dilution of dyed peanut butter with plain peanut butter is shown in Fig. 2.3. The results
are shown in Table 2.1.
