The quality of food products is determined by physical properties, chemical composition, the level of contaminants (microbiological and toxic substances) and sensory attributes. Consumers around the world demand consistent supply of quality food products that reflect the value of the price they pay for them. The nature of raw materials and ingredients reflect the quality of food products in the market. Raw materials as well as packaging materials should be purchased based on the quality specifications that suppliers should adhere to. This review aimed at highlighting the importance of using objective assessment tools and consumer/sensory evaluation in determining the quality and acceptability of new food products. Objective tests are used to measure one particular attribute of a food product rather than its overall quality. They are generally rapid, reliable and repeatable. On the other hand sensory methods measure the reaction to stimuli resulting from the consumption of a product. Sensory testing is often used to determine consumer acceptability of a food product and contributes to the design of quality systems hence considered as a technical support for quality assurance during food production. Not only that but also it helps to obtain feedback for making decisions and carrying out proper modification of a particular food product. Therefore objective methods and sensory evaluation are indispensable tools for routine quality control of new food products as well as the existing ones.
