Study Notes
Food Preservation
- Food preservation prevents food spoilage by preventing microorganisms from multiplying and growing.
- Natural ingredients can preserve food without additives:
- Garlic: antiviral properties, helps fight bacteria.
- Lemon: citric acid, good preservative.
- Salt: excellent preservative, especially Himalayan salt.
- Sugar: prevents water loss, inhibits microorganisms.
- Spices: fight bacteria, maintain freshness.
- Vinegar: acetic acid kills microbes, inhibits spoilage.
Traditional Food Preservation Methods
- Drying/dehydrating: removes moisture to prevent bacterial growth.
- Smoking: uses smoke from burning material to preserve.
- Pickling: preserves food using either salt or vinegar.
- Fermentation: breaks down carbs, produces acids or alcohol, preserves food.
- Salting: draws out water, prevents bacteria growth.
- Curing: adds salt, sugar, nitrites, or nitrates to meat.
Modern Food Preservation Methods
- Pasteurization: heat treatment destroys microorganisms, extends storage time.
- Freezing: easy, convenient, and least time-consuming method.
- Canning: places food in jars, heats to kill microorganisms, extends shelf life.
Tools and Equipment for Food Preservation
- Tools (handheld): knives, peelers, etc.
- Equipment: refrigerators, ovens, etc.
- Mixing tools: wooden spoons, spatulas, tongs.
- Cutting tools: knives, scissors, peelers.
- Measuring tools: measuring spoons, cups, salometer.
- Weighing tools: digital/manual scales.
- Food containers: pots, pans, jars, etc.
- Pressure cookers are for preserving low-acid foods like meat, seafood, poultry, and vegetables.
Food Preservation Process
- Selecting and Preparing Food:
- Fruits & vegetables: sort, wash, peel, and cut.
- Meat, poultry, and seafood: wash, consider additives for preservation.
- Safety in Food Preservation: wash food and utensils thoroughly, use different chopping boards, and clean equipment.
Marketing Preserved Food Products
- Packaging plays a crucial role in marketing products; it attracts attention, communicates brand identity and key product information, and influences customer purchase decisions.
- Different packaging materials like cellophane, cartons, boxes, and wooden boxes are used depending on the product.
- Aluminum is also used for hygiene, keeping aroma, and recyclability, among other factors.
Preserved Food Product Labeling
- Statement of identity (e.g., homemade pickled vegetables).
- Nutrition information (calories, key nutrients).
- Ingredients list (in descending order).
- Manufacturer's name and address.
- Net contents.
- Manufacturing date.
- Expiration date.
