the collaborator at Vitachem Industries (44 Zamboanga St., Quezon City). According to the collaborator,
the vitamin A fortificant was opened in January 2006 and stored thereafter at refrigerated conditions
(10 o C). The vitamin A fortificant was described in the Product Data Sheet supplied by the collaborator as
a greenish-yellow to golden-yellow, oily liquid which may crystallize on storage. It consists of pure
vitamin A palmitate in peanut oil, and contains dl-α-tocopherol as an antioxidant (DSM Nutritional
Products, No date). The vitamin A fortificant was assayed for vitamin A content prior to every use to
determine its actual potency at the time of use.

Method of Sampling and Analysis
One sample each of fortified peanut butter was collected at the start, middle and end of the filling
operations in plastic bottles, for vitamin A analysis. A 10 g sample of the vitamin A fortificant was taken
from the 5 Kg capacity aluminum can and transferred to a 100 mL capacity aluminum can, for vitamin A
assay. The vitamin A content of the fortified product and vitamin A fortificant were analyzed at the FDC
Chemistry Laboratory using AOAC (1995) Official Method of Analysis # 974-29.
