Evaluation and utilization of guava seed meal (<i>Psidium guajava L.</i>) in cookies preparation as wheat flour substitute

Abstract

Abstract Guava seeds were chemically evaluated for their moisture, fat, protein, ash, fibre and minerals content. The fatty and amino acids composition was also studied. Guava seed meal was used in the preparation of cookies. Chemical composition, dough characteristics as well as cookies baking quality were studied to evaluate its possible utilization. The water absorption, dough development time and stability were decreased and dough weakening was increased as the level of guava seed meal in the dough increased. Adding guava seed meal to wheat flour improved volume, specific volume, diameter and thickness of the cookies after baking. Using 9% guava seed meal gave an acceptable, but comparatively inferior product.
