PROTEIN AND AMINO ACIDS PROFILE OF LIMA BEAN (PHASEOLUS LUNATUS) FOODS IN KADUNA STATE

Abstract

This study was conducted to determine the amino acids content of some lima beans (Phaseolus lunatus) foods in Kaduna State. The foods include lima bean porridge, lima bean-benniseed and lima bean-hungry rice. These foods were subjected to amino acids and proximate analysis using standard procedures and analytical methods. Amino acid composition of lima bean-benniseed recorded higher content of essential amino acids leucine (6.97g/100g), lysine (7.10g/100g), methionine (2.60g/100g), threonine (3.81g/100g), and also had higher content of non-essential amino acids, tyrosine (3.45g/100g), alanine (4.54g/100g), serine (3.94g/100g), glutamic acid (12.94g/100g) and aspartic acid (8.68g/100g). Lima bean-hungryrice food had higher content of isoleucine (4.04g/100g), phenylalanine (4.13g/100g), tryptophan (1.26g/100g). Proximate composition shows that the protein content of lima bean-benniseed food (8.33%) and lima bean porridge (8.30%) were significantly (P<0.05) higher than lima bean-hungry rice foodwhile lima bean-benniseed food had higher content of crude fat (13.46%), ash (2.28%) and crude fibre (4.09%) compared to other foods. The carbohydrate content (24.58%) of lima bean porridge was significantly (P<0.05) higher than other foods. The study shows that lima bean foods have a good nutritional profile therefore; increase in the consumption of foods prepared with lima beans could serve as an addition to food-based strategies used in decreasing malnutrition and its effects.
