Valorization of Food Waste: Extracting Bioactive Compounds for Sustainable Health and Environmental Solutions

Area of Science:

• Food Science
• Biochemistry
• Environmental Science

Background:

• Globally, approximately one-third of edible food is wasted, leading to economic losses, food insecurity, resource depletion, and environmental damage.
• Sustainable management of food waste, particularly through upcycling by-products, is crucial for resource optimization and circular economy principles.

Purpose of the Study:

• To review the valorization of food waste for extracting valuable bioactive compounds.
• To highlight the potential of these compounds, especially natural antioxidants and food-derived polysaccharides, as functional ingredients in food, pharmaceutical, and cosmetic industries.
• To bridge the gap between research and practical applications for a sustainable future.

Main Methods:

• Literature review focusing on scientific relevance, methodological quality, and applicability to food, pharmaceutical, or cosmetic sectors.
• Inclusion of studies on the extraction and application of bioactives from food by-products.
• Exclusion of studies lacking empirical data, not addressing bioactives, or published in languages other than English.

Main Results:

• Food waste valorization yields bioactive compounds with potent antioxidant properties, crucial for combating oxidative stress-related diseases.
• Food-derived polysaccharides offer an eco-friendly alternative to synthetic additives in various industries.
• Advanced extraction techniques like enzymatic hydrolysis and ultrasound-assisted methods improve the recovery and efficacy of bioactives.

Conclusions:

• Upcycling food by-products into high-value products is a viable strategy for waste reduction and human health.
• Integrating technological advancements with sustainable practices can transform the food industry towards greater efficiency and environmental responsibility.
• The valorization of food waste supports global sustainability goals by creating valuable products and minimizing environmental impact.
