Consuming the fruit and vegetable juices are considered as a simple and easy method to gain maximum health benefits. Preserving the nutritive value of these juices is important during their storage. So, preservatives and additives are used to increase their shelf life, along with ensuring the product safety. In this study, three kinds of natural preservatives were used to preserve a juice blend obtained from apple, carrot and beetroot under ambient room temperature and refrigerated conditions. The samples were examined every day for any changes in physical parameters and after 7 days, an aliquot of juice was studied for its chemical properties. The sample with lemon juice as preservative and stored under ambient room temperature had no contamination with least amount of reducing sugars and total proteins. Hence, the results observed in this preliminary study corroborate the usage of lemon juice as an effective natural preservative for preserving juice blend of apple, beetroot and carrot.
