Study on the Production of Cookies from Black Gram Compare with Cookies from Mungbean and Pigeon Pea

Abstract

Cookies made from either wheat flour, wheat flour containing 10, 20, 25, and 30% by weight of black gram flour or mungbean flour, or pigeon pea flour were evaluated. It was shown that cookies prepared from wheat flour, wheat flour containing 10% of black gram flour or 10 and 20% of mungbean flour or 10% of pigeon pea flour by weight were the best accepted by the panelists in term of color, flavor, texture and acceptability when compared with the other samples in each group (p< 0.05). The protein contents of the best accepted cookies prepared from wheat flour containing 10% of black gram flour or 20% of mungbean flour or 10% of pigeon pea flour by weight were 7.45, 8.49, and 7.56% on dry weight basis , respectively. The fat contents were 32.84, 26.82, and 28.47% on dry weight basis, respectively while the protein and fat contents of cookies made from wheat flour alone were 6.90 and 31.41% on dry weight basis, respectively. The protein quality of the best accepted cookies made from 10% of black gram flour or 20% of mungbean flour or 10% of pigeon pea flour by weight showed higher chemical score of lysine at 60-69% comparing to 49% of cookies made from wheat flour alone. These were due to the added flours such as black gram flour, mungbean flour and pigeon pea flour whose proteins were rich in essential amino acid lysine content.
