Abstract

LEGUMES ARE ECONOMIC SOURCES OF PROTEIN, ENERGY, VITAMINS AND MINERALS. DESPITE THEIR GOOD NUTRITIONAL QUALITIES, LEGUME CONSUMPTION IS DECLINING WORLDWIDE. LEGUMES COOK IN MANY DIFFERENT WAYS THROUGHOUT THE WORLD. HOWEVER, THEY NEED PROLONGED PREPARATION AND MAY CAUSE SOME GASTROINTESTINAL DISTRESS AFTER EATING. SEED SOAKING IN ORDER TO ABSORB MOISTURE AND SOFTEN THE CRUST AND THE CORE IS USUAL. MOISTURE ABSORPTION RATE DURING EMERSION IN WATER IS DIFFERENT. MOISTURE ABSORPTION HAS AFFECTED BY SIZE OF SEED, AND WATER TEMPERATURE. THE MODEL PRESENTED BY PELEG MATCHES WITH THE EXPERIMENTAL RESULTS OF MOISTURE ABSORPTION MATERIAL IN THE IMMERSION IN THE SHORT-TERM PERIOD TO REACH SATURATED MOISTURE. THEREFORE, IN PRESENT STUDY, USE THE MODEL FOR DETERMINING THE INSTANCE MOISTURE CONTENT OF THREE VARIETIES OF BEANS (TALASH, SADRI AND MAHALI KHOMEIN) AND THREE VARIETIES OF CHICKPEA (DESI, SMALL KABULI AND LARGE KABULI) DURING SOAKING. TO ELIMINATE THE EFFECT OF GRAIN SIZE ON THE RATE OF WATER ABSORPTION, SAMPLES OF GRAINS WITH AN AVERAGE SIZE WERE SELECTED. THE EXPERIMENTS WERE CARRIED AT THREE TEMPERATURES (5, 25 AND 45°C) AND THREE REPLICATE BY USING DISTILLED WATER. FOR EACH VARIETY, THE MOISTURE CONTENT VERSUS TIME CURVES WERE PLOTTED AT DIFFERENT TEMPERATURES. THE CORRESPONDING PLOTTED CURVES FOR EACH VARIETY OF BEAN AND CHICKPEA INDICATED THAT MOISTURE ABSORPTION INCREASING WITH INCREASED TEMPERATURE. THE PELEG MODEL CONSTANTS (K1 AND K2) FOR EACH SAMPLE AT EACH TEMPERATURE SETTLE BY DATA FITTING BY USING MATLAB SOFTWARE. THE OBTAINED CONSTANTS WERE INVESTIGATED REGARD TEMPERATURE. FOR BEAN, THE RESULTS SHOWED THAT AFTER TWO HOURS THE COEFFICIENT OF K1 AND K2 DECREASE LINEARLY. ALSO FOR CHICKPEA, THE COEFFICIENT OF K1 DECREASE LINEARLY AND THE EFFECT OF TEMPERATURE ON THE COEFFICIENT OF K2 WAS PARTIAL AND DECREASING.
