| dc.description.abstract | Utilization of plant sap-derived sugars and syrups, such as palm sugar, birch syrup, maple syrup, and agave syrup, provides versatile alternatives to conventional sweeteners like cane sugar and high-fructose corn syrup, thereby enriching culinary options and catering to diverse consumer preferences. One noteworthy product derived from coconut palm sap is neera, a traditional beverage celebrated for its natural sugars, vitamins, minerals, and bioactive compounds. Its nutritional value and cultural significance make it a cherished component of local diets. It is nutritionally important due to its natural sugars (sucrose, glucose, and fructose), rich in vitamins and minerals (potassium, magnesium, zinc, and iron). The focus of this study is to comprehend the biochemical changes that occur during the conversion of neera into sugar using an open double-jacket cooker. The process entails meticulous monitoring of various parameters, including total soluble solids (TSS), pH levels, total sugar content, reducing sugar content, total phenol content (TPC), antioxidant activity (measured by DPPH and FRAP assays), and ascorbic acid concentration. Throughout the 3 h heating process, samples are collected at 30 min intervals to track the changes in biochemical composition. Continuous stirring and precise temperature control ensure uniform heat transfer and accurate results. The findings reveal significant alterations in biochemical composition, with notable increases observed in TPC and antioxidant activity, possibly attributed to the Maillard reaction. The conversion from neera to coconut sugar yields a range of compositions suitable for various culinary applications, presenting opportunities for entrepreneurship and the development of value-added products. This not only enhances market competitiveness but also fosters economic growth in the food sector. | |
