Food Storage Guidelines

Proper food storage is crucial for maintaining food safety and preventing spoilage. This section details specific storage requirements for different food types.

Highlight: Refrigerator temperature should be maintained between 0-6 degrees Celsius.

Definition: Ambient foods are those stored at room temperature in a cool, dry place.

Storage methods for preventing microorganism growth include:

Freezing at -18 degrees Celsius for long-term storage
Drying to remove moisture
Sugar preservation
Vacuum packing
Pickling in brine or vinegar

Example: Meat and poultry must be stored on the bottom shelf of the refrigerator and defrosted fully to ensure proper food safety.

Local Produce and Farming Methods

This section examines the advantages of local produce consumption and different farming approaches.

Highlight: Local produce offers multiple benefits including reduced CO2 emissions and support for local economies.

Definition: Sustainable fishing involves maintaining adequate fish populations while protecting marine habitats.

Example: Local caught ingredients include:

Mackerel
Haddock
Mussels
Scallops

Comparison of farming methods:

Organic farming: Uses fewer chemicals but yields lower production
Conventional farming: Higher yields but more intensive use of pesticides

Cooking Methods and Nutrient Preservation

This section details various cooking methods and their effects on nutrient retention.

Highlight: Different cooking methods have varying impacts on nutrient preservation and sensory qualities.

Example: Water-based cooking methods:

Boiling: Greatest nutrient loss
Steaming: Better vitamin retention
Blanching: Helps preserve color and nutrients
Poaching: Can lose up to 50% of vitamin C

Definition: Dry cooking methods like stir-frying can preserve nutrients while improving flavor and color.

Food Safety Principles

This comprehensive section covers essential food safety guidelines and high-risk food management.

Definition: High-risk foods are those prone to bacterial growth if not properly stored, prepared, or cooked.

Vocabulary: Key food safety terms:

Use-by date: Strict consumption deadline
Best-before date: Quality indicator
Enzymic browning: Natural food deterioration process

Example: High-risk foods include:

Cooked meat and fish
Dairy products
Shellfish
Gravies and sauces

View

Kitchen Safety and Hygiene

This section outlines essential kitchen safety practices and proper food handling procedures.

Highlight: Proper use of color-coded chopping boards:

Green: Salads and fruits
Blue: Raw fish
Red: Raw meat
Brown: Vegetables
Yellow: Cooked meats
White: Dairy and bakery

Definition: Raising agents include:

Baking powder
Eggs
Yeast
Steam

Example: Essential kitchen hygiene practices:

Hair restraint
Proper apron use
Regular surface sanitization
Proper hand washing
