what are the 4 sensory properties of food?

Beyond taste, sensory properties such as smell, sound, appearance and texture influence what we select to eat. Food must taste delicious, certainly, but mouthfeel, texture, looks and smell are also important to the overall eating experience.

physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.

Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.

The selection of proper packaging materials and systems is an integral part of food process and product design. Robertson (2005) attributes to packaging four functions: containment, protection, convenience and communication.

Taste (gustation) and smell (olfaction) are called chemical senses because both have sensory receptors that respond to molecules in the food we eat or in the air we breathe.

There are four sound qualities: pitch, duration, intensity and timbre.

Most animals share these characteristics: sensory organs, movement, and internal digestion. All of them are illustrated in Figure below. Animals can detect environmental stimuli, such as light, sound, and touch. Stimuli are detected by sensory nerve cells.

The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

Physical properties of food are aspects such as colour, structure, texture, rheology and interfacial properties, and composition. We have a range of instrumental methods for objectively characterising and measuring food structure and physical properties.

In reference to fruits and vegetables, the characteristics that impart distinctive quality may be described by four different attributes—1) color and appearance, 2) flavor (taste and aroma), Address correspondence to: Dr. Diane M. Barrett, Dept.
