This water nourishes the fruit and eventually gets absorbed into the meat of the coconut as it matures. Natural hard ground water samples were collected from … water, pH 10 buffer, HHSNNA indicator (3-Hydroxy-4-(2-hydroxy-4-sulfo-1-naphthylazo) -2-naphthalenecarboxylic acid)/calcium indicator (solid), hardness indicator (solid), 0.01 M standard EDTA (ethylene di-amine tetraacetic acid) were used in the analysis of hardness in water. PATP delivered high phenolic content and retained coconut water original color. As the coconut gets older, it becomes sweeter and contains more meat than water. Ultrafiltration (UF) inhibits the enzymatic activity which is responsible for color changes of coconut water without the need for heat treatment. Raw coconut coir was collected from Rambukkana, Sri Lanka. The effect of pressure assisted thermal processing (PATP) was evaluated on the inactivation kinetics of polyphenol oxidase (PPO) and peroxidase (POD) and selected quality attributes of coconut water. It is a visual component of the product that is often used as an indicator of shelf life acceptability, even though browning by itself may not be indicative of product spoilage.
