Food Selection and Evaluation
- Food selection is influenced by various criteria.
- These criteria can be categorized into different groups
Nutritional Criteria
- Dietary guidelines provide the basis for federal food programs and nutrition education.
Cultural Criteria
- Culture dictates what foods are acceptable to eat.
- Cultural factors influence the types of foods eaten, frequency of meals, and utensils used.
Budgetary Criteria
- Food availability is impacted by geography.
- Technological advancements and transportation improvements lessen geographical limitations on food access.
- Purchasing power influences food choices.
- People on tighter budgets tend to buy less expensive options, while those with more disposable income often opt for convenience foods and dining out.
Religious Criteria
- Buddhism and Hinduism often promote vegetarianism, viewing consuming another living creature's flesh as uncompassionate.
- Jewish dietary laws, known as Kosher, categorize foods into meat, dairy, or pareve (neither meat nor dairy).
- Islamic dietary laws, outlined in the Koran, share some similarities with Jewish dietary laws.
Sensory Criteria: Sight
- Visual aspects influence food choice, including shapes, colours, consistency, portion size, and defects.
Sensory Criteria: Odor

Sensory Criteria: Touch
- Texture describes the qualities felt via the fingers, tongue, and palate, or teeth.

- It includes descriptions of colour, texture, flavour, aftertaste, aroma, and tactile response.
Sensory/Food Evaluation
- Evaluating food using senses includes taste, smell, sight, touch, and sound.
Subjective Evaluation of Food
- Subjective evaluations of food quality are based on sensory characteristics and personal preferences.
- Analytical tests are used to measure differences.
- Affective tests assess preferences.
Food Evaluation: Taste Panels
