Abstract
In Côte d'Ivoire, many varieties of wild beans are frequently consumed. This study was conducted to know the physical parameters (length, width, thickness and weight) and some physicochemical properties of two varieties (white and red) of beans (Phaseolus lunatus). The lengths varied from 11.2±0.2 to 9.6±1.6 mm, widths from 7.9±0.6 to 9.6±1.6, thickness from 4.5±0.3 to 5.0±0.6 and weight from 715±0.03 to 931±0.07g. The capacities and hydration index varied respectively from 0.29±0.00 to 0.40±0.01 g/seed, from 0.40±0.01 to 0.66±0.01. The capacities and solubility index varied respectively from 0.28±0.01 to 0.45±0.02 ml/seed, from 0.65±0.4 to 0.875±0.66. The bean densities are 1.27±0.01 (white) and 1.32±0.01 (Red). Cooking times of bean seeds ranged from 45±2 (White) to 48±2 min (Red). Major physicochemical properties of bean flours are carbohydrates (54.89±0.54-63.03±0.9 mg/100g), protein (23.90±0.43-24.10±0.71 mg/100 g) and fibers (5.35±0.45-5.45±0.45 mg/100 g).The majority minerals in bean flours are potassium (1444.7±4.8-1206.7±2.9 mg/100 g), phosphorus (412±27- 451.91±14.6 mg/100 g) and calcium (268±0.12-297- 84±2.4 mg/100 g). The Ca/P and Na/K ratios of bean varieties flours are less than 1.
Highlights
Lima bean (Phaseolus lunatus L.) is one of the five cultivated Phaseolus bean species, which originated in the Americas [1,2] and have been grown in the New World Tropics for up to ten thousand years [3]
Physic parameters of bean varieties (Phaseolus lunatus) flours are presented in table 1
The length of bean seeds ranged from 11.2 mm to 15.2 mm
Summary
Lima bean (Phaseolus lunatus L.) is one of the five cultivated Phaseolus bean species, which originated in the Americas [1,2] and have been grown in the New World Tropics for up to ten thousand years [3]. Phaseolus lunatus belongs to the family Leguminosae, commonly known as lima bean is one of the important leguminous crops in the genus phaseolus noted for its nutritional and medicinal properties. They are a type of legume native to South American [4]. Lima beans (P. lunatus) are less widely cultivated, they are a very important alternative source of income and food for local populations in regions such a northeastern Brazil [5]. Dry beans are used throughout the world representing 50 % of the grain legumes consumed as a human food source. Lima bean like all other legumes are food resources that offer various optimum nutritional and/ or health benefits [9]
