Introduction

Worldwide food production has expanded dramatically, yet according to the UN Food and Agriculture Organization, each year, one-third of the goods intended for human use are wasted. Additionally, it is predicted that the human population will grow by 2050, necessitating the establishment of a sufficient food supply in order to ensure our ability to prepare food in the future. Population growth will, in this case, result in a rise in food waste, which will be made worse by environmental problems related to its efficient management and disposal. When it comes to waste disposal, food manufacturers confront significant cost problems. Additionally, by emitting CO₂ and other greenhouse gases, the produced wastes have the potential to have a negative impact on the environment.

By 2025, the production of municipal organic wastes is projected to exceed 1000 million tonnes annually due to Europe discarding 50% of its produced food. About 30% of the world's agricultural land is wasted on food. The Food Garbage Index Report estimates that 931 million tonnes of byproducts were produced in 2019; 61% of these wastes were categorised as domestic waste, 26% as waste from the food service industry, and the remaining 13% as waste from retail. Depending on the country, the output of food waste, especially that which is categorised as domestic trash, is correlated with consumer spending power [1].

Description

All leftover food products, including those with improved nutritional profiles, are considered to be food waste. These wastes are a desirable and affordable supply, and depending on where they come from, they have a wide range of nutritional composition. They contain essential ingredients including lipids, proteins, and carbs. They become raw materials with an improved nutritional composition that can be employed in many different sectors. Food by-products may be worth more thanks to the market's growing need for affordable natural products, according to the fragrance industry.

Waste valorization is linked to practical and long-lasting techniques that make recycling and reusing processes easier. By using garbage as alternative sources for the creation of brand-new, high-value products, waste valorization strategies seek to raise the value of a product. These produced items may be adopted by the global economy and help reduce the environmental footprint because they uphold environmental criteria [2].

The fortified bread by whole pomace showed a volume drop, and the results showed a higher moisture content in the crust. Additionally, baking loss was measured, especially for the enriched bread with a 5% w/w content. The fortified bread with whole pomace at 5% w/w was the most consumeracceptable due to its qualities, and whole pomace integration also produced a better phenolic profile. The sensory qualities of French bread might be enhanced by the addition of 1% weight/weight apple pomace. Masoodi and Chauhan studied the inclusion of apple pomace at 2%, 5%, 8%, and 11% in wheat bread compositions [3,4].

The cookies created with the addition of black carrot pomace at different amounts ranging from 0-15% w/w in the flour showed an enhanced fibre profile, which may be connected to the enriched polyphenolic content and antioxidant potential. The largest levels of polyphenols and antioxidant activity were produced by the cookie fortification with 15% weight-for-weight pomace, making it the most efficient.

According to studies, the usage of by-products from the food industry has been extensively used to produce brittle baked goods such cookies, crackers, and biscuits, and their impacts on the finished goods have been assessed. In different amounts, the created byproducts were added into the recipe for cookies. The incorporation of apple by-products in particular is an interesting topic since the various incorporation rates (0 to 30% w/w) had an impact on many aspects of the prepared products. Additionally, the effects of adding apples, potatoes, and carrots to cookies were comparable for the latter. All of the by-products that were added in the cookies affected their colour parameters, regardless of the rate of incorporation, and adding apple and carrot waste also enhanced their antioxidant profile [5].

Conclusion

The creation of novel, workable, and sustainable technologies targeted at the utilisation of by-products produced in many industries is required due to the rising environmental contamination (livestock, food and pharmaceutical industries, etc.). This assessment emphasises the food industry's wastes' rich nutritional makeup and their potential to be transformed into new goods that benefit from their nutritional and functional qualities. This analysis summarised the use of fruit and vegetable byproducts as food additives in the dairy, confectionery, meat, pasta, and pastry industries as well as their usage in livestock and found highly encouraging results. This study also showed the potential for the pharmaceutical and cosmetic industries to utilise agrifood waste, Agri-food wastes should be looked into by the biotechnology and food sectors as an alternative source for the creation of high-value products. In order to evaluate the effectiveness of agri-food by-products as potential sources of bioactive compounds, future perspectives include the use of lowcost and appropriate strategies, the optimization of particular methodologies, the development of novel food and pharmaceutical products enriched with bioactive compounds, and the management of consumer awareness.
