Improvement of the Nutritional Value of Rice Biscuits with Some Vitamins and Minerals Using Soy Flour and Strawberry Powder

Abstract

Aims:  The purpose of this paper is to develop a biscuit incorporated with defatted soy flour and strawberry powder to enhance its nutritional value of it. Methodology: The proportion of rice flour and defatted soy four were 25% and the level of strawberry powder used for making biscuit samples was 0, 5, 10 and 15% respectively. The biscuits were evaluated for their quality based on proximate analysis, physical properties and sensory evaluation. Results:  Based on chemical analysis protein, fiber content and β-carotene level increased with increasing the amount of strawberry powder. The most preferred products were that with 25% defatted soy flour and 10 per cent strawberry powder. It is noticed that 100gm of biscuits with 20% defatted soy flour and 10% strawberry powder provide 4-8 years-old children with 44% of their needs of protein, 20.23% of their needs of iron, 19.06% of zinc and 48.01% of folate. Conclusion: The addition of both defatted soy flour and strawberry powder as a flour replacer in gluten-free biscuits improves its nutritional value without affecting its physical properties and consumer acceptance.
