APPENDIX A PROCEDURAL GUIDELINE FOR THE VITAMIN A FORTIFICATION OF THE SWEET AND CREAMY PEANUT BUTTER 165

Procedural Guideline for the Vitamin A Fortification of the Sweet and Creamy Peanut Butter A. Procedure for the preparation of fortificant 1. Remove the fortificant from the cold storage area and let stand at ambient condition to allow the fortificant to return to its original state. 2. Weigh the required amount of fortificant, i.e. 2.3286 g vitamin A palmitate in a wide mouth opaque bottle with cover. (Note: Weighing of the fortificant should be done as fast as possible to prevent exposure of the fortificant to light and atmospheric oxygen as these factors contribute to the loss of vitamin A. A calibrated analytical balance is likewise recommended for weighing the fortificant to ensure the accurate measurement of the fortificant) 3. Cover the container immediately and set aside until intended use. B. Procedure for the vitamin A fortification of about 155.24 kg of sweet and creamy peanut butter 1. Prepare the peanut butter matrix for receiving the fortificant. This is done by preparing four (4) volumes of sweet and creamy peanut butter according to the established formulation and process flow of the company up to the point in the process where the product has been subjected to a 2 nd grinding step in a colloid mill. 2. Mechanically transfer one (1) volume of ~38.81 kg peanut butter from the stainless steel vessel to the cooling tank. While the peanut butter is being transferred to the cooling tank, slowly pour 2.3286 g vitamin A palmitate to the peanut butter matrix taking care not to splatter the fortificant on the blades of the cooling tank mixer. Pour a small amount of peanut butter into the container of the fortificant and scrape off adhering fortificant with the aid of a rubber spatula and add to the rest of peanut butter in the cooling tank. 3. Manually mix the fortificant with the peanut butter matrix with the aid of a stainless steel ladle until no sign of the fortificant is visible at the surface of the peanut butter matrix. 4. After manual mixing, mix the fortificant-peanut butter mixture mechanically for ten (10) minutes. Stop mixing after the required mixing time. (Note: Since the fortificant is sensitive to heat, oxygen and light, it is recommended that the cooling tank should be covered during the cooling step. It is important that the recommended mixing time of ten (10) minutes per addition of fortificant is followed as excessive mixing may cause incorporation of too much air in the product which could result in the fast degradation of the added fortificant.) 5. Repeat Steps 2 to 4 on another volume of ~38.81 kg peanut butter until all four (4) volumes of peanut butter has been transferred to the cooling tank and fortified. 166
