Sorghum-Soy Blend (SSB) and Sorghum-Cowpea Blend (SCB) fortified blended food aid porridge products were developed as alternatives to Corn-Soy Blend Plus (CSB+) and Super Cereal Plus (SC+), the most widely used fortified blended food aid products. However, the cost and nutrient cost-effectiveness of these products procured from different geographical areas have not been determined.
The objective of this study is to determine the nutrient cost-effectiveness of SSB and SCB compared to existing fortified blended foods.
Nutritional data as well as ingredient, processing, and transportation cost for SSB, SCB, and existing fortified blended foods were compiled. Using the omega value, the ratio of the fortified blended food's Nutrient Value Score to the total cost of the fortified blended food divided by an identical ratio of a different fortified blended food or the same fortified blended food produced in a different country and the nutrient cost-effectiveness of each of the fortified blended foods procured in the United States and several African countries were determined.
Both CSB+ and SC+ are less expensive than SSB and SCB, but they also have lower Nutrient Value Scores of 7.7 and 8.6, respectively. However, the omega values of CSB+ and SC+ are all above 1 when compared to SSB and SCB, suggesting that the existing fortified blended foods are more nutrient cost-effective.
Comparing the nutrient cost-effectiveness of various food aid products could provide valuable information to food aid agencies prior to making procurement decisions.
高粱-大豆混合粉（SSB）和高粱-豇豆混合粉（SCB）强化混合食品援助粥类产品是作为玉米-大豆混合粉升级版（CSB+）和超级谷物升级版（SC+）的替代品开发的，CSB+和SC+是使用最广泛的强化混合食品援助产品。然而，从不同地理区域采购的这些产品的成本和营养成本效益尚未确定。
本研究的目的是确定与现有的强化混合食品相比，SSB和SCB的营养成本效益。
汇编了SSB、SCB和现有强化混合食品的营养数据以及成分、加工和运输成本。使用欧米伽值，即强化混合食品的营养价值得分与强化混合食品总成本的比率除以不同强化混合食品或在不同国家生产的相同强化混合食品的相同比率，确定了在美国和几个非洲国家采购的每种强化混合食品的营养成本效益。
CSB+和SC+都比SSB和SCB便宜，但它们的营养价值得分也较低，分别为7.7和8.6。然而，与SSB和SCB相比，CSB+和SC+的欧米伽值均高于1，这表明现有的强化混合食品在营养成本效益方面更高。
比较各种食品援助产品的营养成本效益可以在采购决策前为食品援助机构提供有价值的信息。
