Take a certain amount of aronia powder, add appropriate amount of hydrochloric acid solution, soak in a constant temperature water bath, gauze filter and wash with water. The obtained starch emulsion is left in the beaker for several hours. Drain the supernatant liquid, stir with water and continue standing. At the same time, the washing was repeated several times and suction filtration under reduced pressure in a Buchner funnel gave wet starch. The wet starch was air-dried and placed in an oven to dry to constant weight. Soak the banana pod powder with hydrochloric acid solution of pH 3.0. The ratio of material to liquid is 1B10 and 45e, soak for 1, 2, 3, 4, and 5 hours, respectively. The extraction results showed that with the extension of the soaking time, the yield of the arachis starch first increased and then decreased. If the soaking time is too short, the binding force between starch and protein is still very strong, and the starch extraction is not enough, resulting in low yield; if the soaking time is too long, the starch will be degraded into glucose, thereby reducing the yield. Therefore, the best soaking time is 4h.
Through the scientific experiments of amylose measuring instruments and other related instruments, it can be concluded that the effect of soaking temperature on the yield of banana pods is achieved by using state 30 hydrochloric acid solution to soak aronia powder. The ratio of solid to liquid is 1B1Q under 4Q4}5Q5}60e respectively. Soaking for 2h, the extraction results showed that when the temperature is lower than 45e, the expansion and softening degree of arachis is not so large, so that the yield of starch is not high (}4); when the temperature is higher than 45e, the yield begins to decline, It is due to the fact that when the soaking temperature is too high, the protein in the arachis will be denatured and the starch will be difficult to separate from the denatured protein, resulting in a decrease in the yield of the starch. When the temperature is 45e, the starch yield is the highest.
Determination of Amylose by Amylose Measuring Instrument
The esculent is widely distributed in Sichuan, Yunnan, Guangxi and other regions. Its tubers are rich in starch, reaching 12% to 18%, of which the content of amylose is 18% to 19%. Between, is a very good quality starch plant. The research on the further development and utilization of turaco is still not very thorough. The market for comprehensive development and utilization is still very large. To be further researched, it is possible that turaco will become the main source of new starch. For the content of amylose can be effectively measured using amylose measuring instrument to provide a reliable basis for development and utilization.
