บทคัดย่อ ( Abstract )
This research project aims to development of concentrates banana blossom ready to drink. The extraction conditions were studied at 70 and 90°C for 3, 4 and 5 hours for physical composition analysis and the chemistry of the concentrated banana blossom juice. The extraction conditions at 70 °C for 4 hours is the optimal conditions for extracting banana blossom juice. Total soluble solids were 1.0 °Brix, pH were 5.38, The L*, a* and b* were 23.44, 0.34 and 0.81 respectively. The antioxidant activity, phenolic compounds and tannin acid were 48.5599%, 248.8521 gallic acid/g and 11.8789 mg of tannic acid/g respectively. Then concentrated at a temperature of 40 °C a pressure of 20 mbar concentrated banana blossom juice with total soluble solids of 4 °Brix, pH was 5.79, L* value were 30.89, 0.70 and 1.87 respectively. While the antioxidant content was 217.4873%, the total phenolic compound content was 797.3147 mg gallic acid/g and the tannin content was 19.0408 mg tannic acid/g. In developing the right recipe for a drink with concentrated banana blossom juice product, sensory preference was tested using a 9-point hedonic scale. scale. It was found that the formula containing concentrated banana blossom juice 90:10 of dates was the formula that was accepted by the most tasters. With an overall liking score of 6.57 and to study shelf life by bringing water banana blossom extract packaged in a glass bottle sealing locks 75 ml pasteurized at 70 °C for 15 minutes and stored at refrigeration (4 ± 2 °C) for a time. 0, 4, 7 and 10 days. Total soluble solids were found to be in the range of 9.80–9.97 °Brix, pH in the range of 5.67–5.69, L*, a* and b* in the range of 33.87–34.09, 2.51–2.65 and 5.43–5.66 respectively. The amount of antioxidant activity in the range 269.4649–283.7051% The phenolic compounds was in the range. 739.5729–847.7324 mg gallic acid/g and tannin acid was in the range of 12.6214–17.1210 mg tannic acid/g and total microbial content was in the range of 1.3667–1.5000 CFU/mL.
