Mukwano uses a dilution process to <strong>in</strong>troduce vitam<strong>in</strong> A <strong>in</strong>to a one-ton, sta<strong>in</strong>less steel,<br />

pre-mix<strong>in</strong>g tank <strong>and</strong> mixes the vitam<strong>in</strong> A for 30 m<strong>in</strong>utes. 11 After mix<strong>in</strong>g, the <strong>oil</strong> is<br />

pumped 12 <strong>in</strong>to a 50-ton hold<strong>in</strong>g tank where it is mixed for another 30 m<strong>in</strong>utes.<br />

In 2005, the MOST project sponsored <strong>oil</strong> fortification pilot trials <strong>in</strong> Mukwano. The<br />

company purchases the vitam<strong>in</strong> A fortificant quarterly <strong>and</strong> ma<strong>in</strong>ta<strong>in</strong>s good daily records<br />

<strong>of</strong> the vitam<strong>in</strong> A usage (Ranum, June 2007).<br />

Mukwano reported that it purchased new chemicals <strong>and</strong> equipment to comply <strong>with</strong> the<br />

UNBS <strong>in</strong>-plant quality control (QC) requirements. Additional tra<strong>in</strong><strong>in</strong>g <strong>in</strong> the new<br />

laboratory methods is also required. The <strong>in</strong>-plant QC consists <strong>of</strong> prepar<strong>in</strong>g composite<br />

samples (mix <strong>of</strong> <strong>in</strong>dividual samples obta<strong>in</strong>ed every hour) per batch (large tanks) that they<br />

process. The company produces approximately seven batches per day.<br />

To meet UNBS QC requirements, Mukwano has assigned one person (per shift) to<br />

oversee the vitam<strong>in</strong> A blend<strong>in</strong>g process.<br />

Mukwano’s other fortification costs <strong>in</strong>clude: advertisements (Sunday section <strong>of</strong> several<br />

papers regularly carries a prom<strong>in</strong>ent advertisement) <strong>and</strong> a j<strong>in</strong>gle used on radio. These<br />

costs are factored <strong>in</strong>to the company’s general market<strong>in</strong>g <strong>and</strong> product differentiation<br />

strategy are not considered unique to fortification <strong>and</strong> thus are not <strong>in</strong>cluded <strong>in</strong> cost<br />

estimates.<br />

b. BIDCO Oil <strong>Fortification</strong> Process<br />

The BIDCO plant, located <strong>in</strong> the town <strong>of</strong> J<strong>in</strong>ja, began operations <strong>in</strong> June 2005. In 2007,<br />

it produced 4,500 MT/month <strong>of</strong> vegetable <strong>oil</strong> <strong>and</strong> 850 MT/month <strong>of</strong> fat. The plant<br />

currently operates at 150 tons per day or 60 percent <strong>of</strong> its capacity. Most fat is sold to<br />

bakeries, although two br<strong>and</strong>s (Kimbo <strong>and</strong> Cowboy) are consumer goods. All vegetable<br />

<strong>oil</strong> is fortified <strong>with</strong> both vitam<strong>in</strong> A <strong>and</strong> D; the <strong>oil</strong> is added directly to a mix<strong>in</strong>g tank <strong>and</strong><br />

mixed for 30 to 60 m<strong>in</strong>utes. The <strong>oil</strong> is then pumped <strong>in</strong>to a hold<strong>in</strong>g tank for an additional<br />

30 m<strong>in</strong>utes <strong>of</strong> mix<strong>in</strong>g <strong>and</strong> then packaged. No pre-dilution is prepared. The premix is<br />

weighed out for each batch <strong>in</strong> the lab <strong>and</strong> a log book is ma<strong>in</strong>ta<strong>in</strong>ed to document the<br />

vitam<strong>in</strong> A addition. Samples are sent to UIRI monthly for quantitative vitam<strong>in</strong> A test<strong>in</strong>g.<br />

c. Plans for Introduc<strong>in</strong>g <strong>Fortification</strong> <strong>in</strong> Other <strong>Vegetable</strong> Oil Plants<br />

The Muddu Oil Company, located just outside <strong>of</strong> Kampala <strong>in</strong> Mukona, is another<br />

recently constructed plant that will rely on imported palm <strong>oil</strong>. Although fortification<br />

discussions were held, its output level has been about one-third that <strong>of</strong> BIDCO <strong>and</strong><br />

Mukwano. The company is currently reported to be bankrupt <strong>and</strong> <strong>in</strong> receivership.<br />

E. The Cost <strong>of</strong> Fortify<strong>in</strong>g <strong>Vegetable</strong> Oil<br />

11 The $15,000 tank was donated by the MOST Project <strong>in</strong> 2004. It has an estimated lifespan <strong>of</strong> 20 years.<br />

12 The pump was also donated by the MOST Project.<br />
