Food waste is a staggering problem that affects not only our environment but also our wallets and our health. According to the United Nations Food and Agriculture Organization, one-third of all food produced globally is lost or wasted.
This translates to approximately 1.3 billion tonnes of food that could have been consumed by humans. The consequences of food waste are far-reaching, however, there is hope. By embracing natural preservation methods like freeze drying, chemical-free dehydration and bottling, we can significantly reduce food waste while maintaining the nutritional value and flavour of our food. In this article, we take a step back to explore the benefits of these methods and how they can help us create a more sustainable food system.
THE FOOD WASTE REALITY
Food waste occurs at every stage of the food supply chain, from production and processing to distribution and consumption. By reducing food waste, we can help alleviate hunger and poverty, reduce the financial burden on households and businesses, and minimise the environmental impact of food production. Natural preservation methods can play a significant role in reducing food waste by allowing us to preserve seasonal produce and enjoy it year-round.
FREEZE-DRYING: NATURE’S NUTRIENT PRESERVER
Freeze drying is a modern and highly effective method of food preservation. It involves freezing the food and then reducing the surrounding pressure to allow the frozen water in the food to sublimate directly from the solid phase to the gas phase.
The freeze-drying process:
- Retains up to 97% of original nutrients: Freeze drying preserves the vitamins, minerals, and other beneficial compounds in food, making it a highly nutritious option.
- Maintains flavor and texture: The food retains its original taste and texture, ensuring that it remains enjoyable to eat.
- Extends shelf life: Freeze-dried foods can last for years without the need for refrigeration, making them ideal for long-term storage.
DEHYDRATION: AN ANCIENT TECHNIQUE WITH MODERN BENEFITS
Dehydration is a traditional method of food preservation that has been used for centuries. It involves removing moisture from food to prevent the growth of bacteria, yeast, and mould.
Dehydration:
- Preserves nutritional value: While some nutrients may be lost, dehydrated foods still retain a significant portion of their vitamins and minerals.
- Enhances flavour: The concentration of flavours makes dehydrated foods particularly delicious.
- Is energy-efficient: Dehydration uses less energy compared to other preservation methods, making it an eco-friendly choice.
Dehydration is a great way to make healthy snacks like fruit leathers and veggie chips, are also compact and lightweight, making them easy to store and transport.
FERMENTING AND STORING FOOD IN BOTTLES : A TIME-TESTED METHOD
Fermenting food is an ancient technique that not only preserves food but also enhances its nutritional value and flavour. Storing fermented foods in bottles is a practical and safe way to keep them fresh for extended periods.
Fermenting and bottling:
- Enhances nutritional value: Fermentation increases the bioavailability of nutrients and produces beneficial probiotics.
- Preserves freshness: Properly fermented and bottled foods can last for several months without the need for refrigeration.
- Adds flavours: Fermentation imparts unique and complex flavours to foods, making them more enjoyable to eat.
- Promotes gut health: The probiotics in fermented foods support a healthy digestive system.
TIPS AND RECIPES TO GET STARTED
Preserving food naturally can seem daunting, but it's easier than you think.
Here are a few tips and recipes to get you started:
- Start with seasonal produce: Preserving food that's in season is not only cost-effective but also ensures that you're getting the best flavour and nutritional value.
- Invest in a freeze dryer or dehydrator: These appliances can be a significant investment, but they're worth it in the long run. You can also start with smaller, manual preservation methods like sun drying or using a food dehydrator.
- Experiment with different recipes: Preserving food is an art, and there are countless recipes and techniques to try. Experiment with different flavours and ingredients to find what works best for you.
- Join a community: Preserving food naturally is a community-driven effort. Join online forums, attend workshops, and connect with other like-minded individuals to learn new techniques and share recipes.
CONCLUSION
Embracing natural preservation methods through fermentation, bottling, freeze-drying, and dehydration isn't just about reducing waste – it's about reconnecting with traditional food wisdom while utilising modern innovations. These techniques offer practical, healthy solutions for sustainable living while creating nutrient-rich, flavourful foods that can be enjoyed year-round.
