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

Procedural Guideline for the Vitamin A Fortification of Peanut Butter
using Collaborator's Horizontal Mixer
A. PREPARATION OF FORTIFICANT
Per recommendation of the supplier (BASF Philippines, Inc. Emerald Building, Emerald Avenue,
Pasig City), pre-heat the vitamin A palmitate prior to use to 40ºC in its container using a water bath
for 15 minutes.
B. PREPARATION OF PEANUT BUTTER PREMIX USING COLLABORATOR’S
HORIZONTAL MIXER
1. Prepare plain peanut butter using the procedure of the industry collaborator, as shown in Fig. 2.8.
After the homogenization step, ensure that the prepared peanut butter is cooled to a temperature
of 65ºC or lower prior to use.
2. Weigh 40 kg of the plain peanut butter prepared in Step B.1 in a stainless steel container using a
platform balance.
3. Weigh the require amount of fortificant with the aid of a medicine dropper in a beaker using a
balance. For every 40 kg of plain peanut butter, 40 g of vitamin A palmitate (Assay: 1.0 – 1.1
Million IU) will be needed.
4. Pour the pre-weighed fortificant (40g) contained in a beaker directly at the center of the 40 Kg preweighed
peanut butter contained in a stainless steel container. Store the remaining fortificant at
refrigerated conditions in an aluminum container with cover.
5. Ensure that all of the fortificant in the beaker is transferred by adding a little amount of the preweighed
peanut butter into the beaker in areas where adhering fortificant id present. Scrape off
the peanut butter from the beaker making sure that no fortificant is left adhering on the container.
Add the scrapings back to the container of the pre-weighed peanut butter.
6. Manually mix the fortificant with plain peanut butter contained in the stainless steel container from
Step B.4. Mix using circular strokes with the aid of a spatula until no sign of the fortificant is
visible at the surface of the peanut butter mixture. Mix for approximately one minute.
7. Pour the fortificant-plain peanut butter mixture in the stainless steel container into the horizontal
mixer. Make sure that all adhering peanut butter in the stainless steel container is totally scraped
off with the aid of a spatula and added into the horizontal mixer.
8. Switch on the horizontal mixer to start mixing the fortificant-peanut butter mixture. Mix for ten
minutes.
(Note: Recommended mixing time of ten minutes should be strictly followed. Excessive mixing of the
premix causes the incorporation of too much aire in the premix that could lead to degradation of the added
fortificant.)
