About This Book

The bulletin presents practical guidance for producing and controlling tomato pulp, ketchup, and chili sauce, covering sanitary factory practices, raw-material selection, processing steps, and quality considerations. It describes the composition of whole and trimming-stock pulps and provides laboratory procedures — microscopic examination and chemical and physical analyses — to determine total and insoluble solids, sugars, acidity, salt, and specific gravity, with attention to accuracy and evaporation to target concentration. Manufacturing methods and factory controls for ketchup and chili sauce are outlined, supported by tables, figures, and calculation aids for concentration and volume.
