Abstract
Type of Study: A cross-sectional study will be conducted in Nsanje among children and
their caregivers to determine their sensory acceptability and consumer preference for new orange fleshed sweet potato (OFSP) varieties bred in Malawi.
Problem Statement: OFSP are some of the bio-fortified crops bred in Malawi. However,
bio-fortification results into different visual phenotypes and taste changes than pre-existing varieties of the crops. Due to these changes, sensory attributes are also affected and acceptability of these newly introduced varieties is a challenge.
Main Objective: To assess consumer preference and sensory acceptability of new biofortified orange fleshed sweet potato varieties bred in Malawi by International Potato
Centre (CIP) among children aged 12-59 months and their caregivers in Nsanje Malawi.
Specific Objectives: i) To assess sensory acceptability of new OFSP varieties among
children aged 12-59 months. ii) To determine consumer preference for new OFSP varieties among caregivers of children aged 12-59 months. iii) To assess sensory acceptability of new OFSP varieties among caregivers of children aged 12–59 months.
Methodology: New OFSP varieties that will be assessed in this study are Anaakwanire,
Kaphulira, Mathuthu, Royal Choice, Mthetsanjala and Msungabanja. These varieties will
be assessed against local sweet potato varieties grown in Malawi. Plate waste and hedonic
Likert scale sensory techniques will be used to assess acceptability of the sweet potatoes among children aged 12-59 years. Paired preference test and preference ranking sensory procedures will be used to assess consumer preference for the sweet potatoes among caregivers of children aged 12–59 months. Pearson correlation co-efficient will be used to measure likeness, preference and levels of satisfaction of the sweet potatoes among children and caregivers.
Expected results: The study expects to find acceptability of new OFSP among children
and caregivers to reduce Vitamin A Deficiency which is a public health concern in Malawi
and drivers of consumers preference for new OFSP varieties.
Dissemination: The findings will be disseminated through conference presentation to
KUHEs-COM, CIP, UNICEF, DNHA, The Hunger Project, Nsanje District Council, others
nutritional stakeholders and journal publication for utilization. For academic purpose, a
copy of the dissertation will be sent to Kamuzu University of Health Sciences, COMREC
and KUHES libraries for reference.
