Determination of total phenolic content in different varieties of date / Farhana Rosly

Date is well known among the Malaysian even though its origin is from the Middle Eastern countries. It is rich in simple sugars such as glucose and fructose (65 -80%), and a good source of fibers and some essential minerals, but low in fat and protein with no starch. The purpose of this study is to...
