Nutritional and biochemical attributes of present juice and Gur produced from date palm trees

Abstract

Investigation of\r\nnutritional, biochemical analysis and mineral contents of Phoenix sylvestris\r\nL. juice and gur is an important issue. Five different protectors;\r\ncontrol (No protection), bamboo net, nylon net, nylon & bamboo net and\r\nplastic chot were used during juice collect from pate palm plant. Gur\r\nsamples were collected from a variety of sources, including gur prepared\r\nby SAU machines, contact growers by traditional method, and Jashore and Khulna\r\nlocal markets. The results revealed that juice collected from plants using\r\nprotector showed better performance compared to plant using no protectors. The\r\nmaximum juice quantity was recorded in the plants protected with bamboo + nylon\r\nnet, which also had the highest levels of total soluble solids, potassium,\r\nphosphorus, pH, and phenol and the least amount of bacterial contamination. The\r\ngur collected from local market of Jashore and Khulna had more sugar and\r\nbacterial contamination. However, gur produced from SAU-machine had\r\nsubstantially higher total soluble solids, vitamin C, titratable acidity and\r\ntotal phenol. Gur generated by the SAU-machine contains a significant\r\nlevel of K (756.33 mg/100 g), Ca (262.06 mg/100 g), and P (231.69 mg/100 g),\r\nindicating that high-quality gur produced by controlled condition can be a rich\r\nsource of minerals.
