Citrus fruits are a widespread fruit crop and belong to the Rutaceae family. Citrus fruits include orange, tangerine, lime, lemon, sour orange and grapefruit. Citrus fruits are not only used for table purposes, but also in processing industries to make value added products such as marmalade, jams, juice, jellies, etc. which leads to the generation of waste into peel (rind) and seeds. The main fruit waste i.e. peels and seeds. The peel (skin) can be used for the preparation of sweets (candies). The use of citrus peel will not only improve the utility, but also serve to reduce the pollution load on the environment. It is nutritionally fortified with ascorbic acid, vitamin B, calcium, phosphorus, and other beneficial compounds essential for overall health. Citrus peels are enriched with pectin, cellulose and hemicelluloses, bioactive compounds and other compounds beneficial to health. The moisture content of the fresh citrus peels was 89.49% and the acidity in terms of citric acid was 0.40%. The ascorbic acid content was 87.49 mg / 100 g. The bitterness that prevails in citrus peels has limited its added value, demand and relevance. Limited work has been done on the processing and post-harvest management of citrus. In this article, we have presented and discussed the efforts of researchers around the world regarding waste use and value addition. In this review, we have tried to compile previous research information in an accurate way to improvise the benefits and full use of citrus waste.
