It is also used in medicinal preparations. Because coconut water kefir is fermented, beneficial bacteria and yeast transform the natural sugars found in coconut water — releasing powerful metabolites that can benefit the human body. During germination, water completely disappears. It acts as a natural energy or a sports drink, as it is rich in mineral contents (sodium, potassium, phosphorus, chloride, magnesium), vitamins, sugars, proteins, free amino acids, antioxidants (catechin and salicylic acid), and growth promoting factors (Yong et al., 2009). TCW agar medium therefore incorporates all the nutrients present in TCW. At the same time, recovery of TAA was 87%. Coconut producers and vendors in Guyana and other Caribbean Community (Caricom) member states will soon have to abide by new food safety standards for coconut water after scientists found a high percentage of bacteria though no one has been sickened by coconut water… Glucose and fructose content in nanofiltered permeate were completely recovered, while the concentration of total polyphenols, TAA, and many bioactive components in the retentate of NF increased many folds. According to these authors, the inactivation of S. cerevisiae was increased from 0.3 to more than 5 log reductions when the treatment temperature was raised from 25 °C to 50–60 °C. Thakur and DasGupta (2006) carried out clarification and concentration of beetroot juice by an integrated process comprising of ET, centrifugation, UF, RO, and thermovacuum evaporation. Like coconut water, coconut milk is also prone to microbiological damage. 1. Gabriel et al. The composition of coconut water changes during the course of ripening of the fruits and in germination. All water has bacteria and protozoans to some extent, most of them completely harmless. After that, the permeate from UF was passed through RO using composite PA membrane packed in spiral wound module and operating pressure range of 1–69 bar. The production of coconut sugar from unfermented sap is a profitable on-farm activity and is encouraged in many coconut growing countries for local consumption as well as for export marketing.
