The young rice juice obtained after grinding the sample is dried through a spray dryer at 160oC until it has a powder form (moisture reaches 7-8%).<\/p>\n\n\n\n
Harvest time: evaluate the criteria as 8 days, 10 days and 12 days after sowing.<\/p>\n\n\n\n
The treatments were arranged in a completely randomized design with 2 treatments (wheat and high yielding rice) and 3 replicates.<\/p>\n\n\n\n
Monitoring criteria: yield (HSTH) and chlorophyll content on rice leaves (chlorophyll a, chlorophyll b, total chlorophyll).<\/p>\n\n\n\n

The results of analysis of the recovery efficiency of wheat flour at 8 days, 10 days, 12 days after sowing showed that the product recovery efficiency at day 12 was the highest (2.59%) than 95% The yield on day 8 (1.33%) and was 23% higher than that on day 10 (1.64%).<\/p>\n\n\n\n

The results of the analysis of the yield of high yielding rice flour at 8 days, 10 days, and 12 days after sowing showed the highest yield of young rice flour at day 10 (1.58%), higher than 42% performance on day 8 (1.11%) and 14% higher performance on day 8 (1.11%).<\/p>\n\n\n\n

Through the analysis data of the yield of wheat flour and high yielding rice flour, it was found that the yield of wheat was higher than that of high yielding rice. At day 8, the yield of wheat was 1.2 times higher than that of high yielding rice, and the yield of wheat was 1.04 times higher than that of high yielding rice at day 10 and 2.04 times that of day 12.<\/p>\n\n\n\n
High yielding wheat and rice flour
Results of analysis of chlorophyll a content on rice leaves<\/p>\n\n\n\n
Through analysis of chlorophyll a content on rice leaves, we found that chlorophyll a content of wheat was much higher than that of high yielding rice: 4.67 times higher at day 8, 4.50 times higher at day 10, however in On the 12th day, the chlorophyll a content of wheat was only 0.80 times that of high yielding rice.<\/p>\n\n\n\n
In high-yielding rice, chlorophyll a content increased steadily over the period, however, from day 10 to day 12, chlorophyll content decreased sharply from 4.01 (mg\/g) to 1.31 (mg\/g).<\/p>\n\n\n\n

For chlorophyll b content, the content in wheat over the 8 days, 10 days and 12 days after sowing was higher than in high yielding rice and was stable across the measurements, not changing much with the time of sampling. .<\/p>\n\n\n\n

*In general, the chlorophyll a, chlorophyll b and total chlorophyll contents of wheat were higher than those of high yielding rice. The chlorophyll a content varied greatly over the sampling period, but the chlorophyll b and total chlorophyll content in both rice varieties did not change much over time.<\/p>\n\n\n\n
The research was conducted in order to improve the economic value of value-added products and exploit the nutritional value of rice, make use of the waste products of rice leaves to contribute to reducing the impact on the environment. Accordingly, building a process to produce young rice flour based on spray drying technique and without drying the raw materials before grinding will minimize the oxidation and loss of chlorophyll content in rice flour.<\/p>\n\n\n\n
