Qualitative Changes during Storage of Different Ginger-Based Spice Sauces

Ready-to-eat sauces have become a trend in all kinds of meals. Five ginger-based sauces viz., ginger, ginger-black pepper, ginger-nutmeg, ginger-kokum and ginger-nutmeg-kokum were prepared as per standard procedures. Physical, biochemical, microbiological and rheological properties of the sauces were recorded at regular intervals for 135 days. There was no significant variation in physical properties (total soluble solids) during storage but colour value varied significantly. Variation in chemical parameters like pH, content of moisture, proteins, carbohydrates and total sugars was non-significant, but variation in titratable acidity and reducing sugars was significant. Storage period did not affect total plate count, consistency index and flow behavior index of the sauces, which remained constant during the entire storage period. Sensory score of the sauces showed that acceptability was high for ginger sauce, followed by ginger-black pepper and ginger-nutmeg sauce.
