This study aimed to develop instant tomato sauce powder (ITSP) using whole tomatoes (ITSP-P1) and tomato puree (ITSP-P2). Both were coated with maltodextrin and xanthan gum before being dried with hot air. Reconstituted tomato sauces, RTS-ITSP-P1 and RTS-ITSP-P2, were prepared from ITSP-P1 and ITSP-P2, respectively. ITSP-P2 exhibited lower moisture content, water activity, and wettability while demonstrating higher solubility and flow properties than ITSP-P1. Both reconstituted tomato sauces (RTS-ITSP-P1 and RTS-ITSP-P2) showed non-Newtonian and pseudo-plastic behavior and had closely aligned color, pH, acidity, and total soluble solids. Total carotenoid, lycopene content, total phenolic content, and vitamin C, were higher in reconstituted tomato sauce than in commercial sauce. Neither powder nor sauce exhibited any total bacterial count, yeast, or mold during the storage period. Both samples of reconstituted tomato sauce were well-accepted by consumers. Results demonstrate that quick tomato sauce powder and reconstituted sauce can serve as substitutes for commercial tomato sauce.
