Impact of Leaf Juice Storage Time on the Yield and Quality of Leaf Protein Concentrate (LPC) from Pea (Pisum Sativum L.)

Abstract: Green Crop Fractionation (GCF) produces Leaf Protein Concentrate (LPC), but rapid autolysis and microbial activity after maceration can reduce nutrient recovery. This study examined how storage time (0?33 hours) affects the chemical composition of pea (Pisum sativum L.) leaf juice and its LPC yield. Significant declines were observed in juice dry matter, nitrogen, and water-soluble reducing sugars, leading to a marked reduction in LPC yield (4.82 to 2.94 g/100 ml) and nutritive value. While DPJ dry matter also decreased, its nitrogen content increased, indicating reduced nitrogen incorporation into LPC. Results demonstrate that pea leaf juice deteriorates rapidly, and storage beyond 3 hours severely diminishes LPC recovery and quality. Immediate processing is therefore essential for efficient GCF.
