How do food manufacturers of sauces and dressings distinguish their premium brand products? Taste comes first and foremost. Not far behind is the handling property—namely, visual appearance in the bottle and flow behavior when poured on salad. Consumers judge “thickness” and “creaminess” in the supermarket by holding the bottle and moving it gently from one side to another. Perception of how the dressing is likely to pour comes from this simple action. In general, careful application of dressing requires controlled flow from the bottle so that just the right amount comes out. Customer dissatisfaction arises when too much dressing gushes suddenly from the bottle or the squeezing action cannot get sufficient quantity to expel within a short time frame.
