Chapter 1: The Food Waste Dilemma

Currently, food security is a pressing global concern, with approximately 828 million individuals uncertain about their next meal. This troubling statistic has risen, partly due to the COVID-19 pandemic, alongside issues like climate change and conflicts. Paradoxically, large quantities of food are discarded worldwide, with around 14% wasted between harvest and retail, and another 17% thrown out after retail. In total, nearly one-third of all food produced is lost, which could suffice to nourish 2 billion people—nearly 2.5 times the number currently facing hunger.

A significant factor contributing to this wastage is the disposal of by-products, which are the remnants of food production. While some by-products are intentionally discarded due to undesirable taste, others, such as seeds and hulls, are overlooked simply because their potential uses are unknown.

Interestingly, about 44% of these by-products are derived from fruits and vegetables. This is unfortunate, considering these leftovers possess valuable nutrients and health benefits, such as cancer and diabetes prevention. Fortunately, these by-products can be repurposed effectively.

The first video titled "Compost Solution / Don't Waste Your Leftover Fruit and Vegetables" provides insights into composting techniques that can help reduce food waste.

Chapter 2: Transformative Uses for By-Products

1. Enhancing Bread with By-Products

One effective method to utilize vegetable and fruit by-products is by incorporating them into bread. For instance, flaxseed hulls, a by-product of oil extraction, can be added to wheat bread to enhance its health benefits by combating oxidative stress.

Another valuable addition is pea hulls, which are the remnants after extracting protein-rich pea balls. These hulls can increase the fiber content of bread, as they account for 10-14% of the total pea weight.

Black bean seed coats, a by-product of pulse processing, can also improve bread quality. When added at a rate of 0.5%, they maintain the bread's texture and baking properties.

Additionally, tomato pomace, the pulpy remains from juice production, enriches bread with minerals like potassium and magnesium. An optimal addition is around 6% pomace to ensure both nutrition and texture.

2. Wholesome Cookies and Biscuits

Vegetable and fruit by-products can also enhance the nutritional profile of cookies and biscuits. For example, soybean hulls, a by-product of the soy industry, can be mixed into cookies to increase fiber and protein levels while maintaining their original texture.

Grape pomace, a by-product from winemaking, can be added at 20-30% to cookie recipes, improving their health benefits and altering their color and texture.

Pomegranate peels, another by-product from juice extraction, can also be incorporated into biscuit dough to boost fiber, calcium, and iron content, although they may affect the dough's consistency.

The second video, "5 Ways to Get Rid of Vegetable Scraps," explores various creative strategies for utilizing vegetable remnants effectively.

3. Nutritional Noodles

Incorporating by-products into noodles is another way to enhance their nutritional value. Legume seed coats can be added to noodles, providing extra fiber and lowering the glycemic index, which may assist in managing blood sugar levels.

Apricot kernels, a by-product of fruit processing, can also be included, increasing lipid and protein content while reducing cooking time.

4. Other Creative Uses

Vegetable and fruit by-products can be utilized in numerous other culinary applications. For example:

• Tomato pomace can be transformed into low-calorie jams.
• Apple pomace can enhance cake dough.
• Grape pomace can be added to cheese, yogurt, and salad dressings.
• Tomato peels can provide natural coloring for ice cream.

Conclusion: Taking Action

The potential for reusing vegetable and fruit by-products is vast. By creatively incorporating grape pomace into various recipes or utilizing hulls in baked goods, we can make a significant impact on reducing waste.

Here are some practical suggestions for repurposing leftovers:

• Using tomato pomace in bread.
• Incorporating pomegranate peels into cookies.
• Opting for products containing fruit and vegetable remnants.
• Creating candles from leftover orange peels.
• Brewing tea from avocado pits.
• Transforming overripe bananas into smoothies or spreads.
