ABSTRACT Coconut sap is consumed as a juice or used as raw material for fermentation to produce beverages with various health benefits. Coconut sugar, a brownish crystalline powder obtained by the evaporation of the unopened coconut inflorescence sap (Cocos nucifera L), is a traditional sweetener in Asian countries and is considered globally as a ‘nutritious’ and ‘low glycemic’ natural sweetener (Alexandru Grumezescu, 2019, pp. main rachis with branches bearing flowers on pedicels). Flowers are … Stage 1 - The inflorescence, which was situated just above the freshly open inflorescence in the palm (the inflorescence which is to open next) Fig 2: Schematic diagram of different maturity stages of inflorescences within the coconut palm. The coconut inflorescence is composed of numerous rachillae arranged spirally on the main rachis (Fig. Spathe and inflorescence. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate).
