Ready to drink Calamansi juice is an all-natural juice drink made from the fruit of Citrus microcarpa Bunge, a fruit indigenous to the Philippines and South East Asia. The fruits are available throughout the year and the peak season of harvest is in mid-August through October.
The fruit is a good source of Vitamin C and a fair source of provitamin A. It is commonly used as an ingredient as an acidulant in various food products such as condiments, jams, and jellies. The process of making ready-to-drink calamansi juice includes the following steps: 1) selection and washing of fruits; 2) cutting of fruits and juice extraction; 3) preparation or mixing of ingredients according to the desired formulation; 4) pasteurization; and 5) hot filling and bottling. Pasteurization and bottling will give the juice a longer shelf-life.
The product can be stored at room temperature or better at refrigerated temperature to keep its flavor and freshness for a longer period of time.
