Use of non-conventional methods for the extraction of value-added products from citrus waste

Oranges, grapefruit, lemons, limes, and mandarins are just a few of the citrus fruits that are grown most frequently worldwide. Nearly half of the weight of fresh fruit is wasted in the citrus processing business, which generates enormous amounts of trash. Orange juice results in a significant quantity of waste generation. The bioactive chemicals are typically extracted from orange peel using traditional extraction methods. carotenoids are hydrophobic and unstable at higher temperatures, under the influence of light and oxygen, and under other external conditions, their usage in food, cosmetic, and pharmaceutical goods is restricted. The use of safer and less harmful substitutes has begun to be addressed, and it has been a priority to reduce the negative effects that solvents routinely used in industry have on the environment and human health. The major classes of carotenoids, chlorophyll, anthocyanin, and betalains are represented by the pigments that the UAE is stated to have extracted from by-products. Conventional techniques that use organic solvents have a same negative environmental impact as citrus waste because they demand lengthy extraction times, a lot of energy, and other resources.
