Hi

Snack foods are quite varied, from potato chips to roasted nuts and pretzels, and from crackers to candy and peanut butter. They range in flavors that include sweet, sour, bitter, salty, savoury, metallic and even pungent. Measurement techniques will vary depending on the snack food type, which often include coarse, non-homogeneous and irregularly shaped food products.

Most snack foods will be opaque in nature so are best measured using a Directional 45°/0° reflectance instrument. This is the measurement mode and geometry that most closely matches the way the human eye 'sees' colour. It is also important to ensure the instrument has a large area view since the snack food will typically be contained in a sample holder like a petri dish or bowl.
