It was already cultivated for commercial purposes in the latter half of the Meiji era.In the Taisho era, pickled plums are indispensable as a regular food for the military. The cultivation area was increased at a quick pace, and the production volume also increased. Furthermore, in the early Showa period, demand from the military increased. However, at the same time as the end of war in 1945, actual demand plummeted. Most of the Ume trees are cut down, and sweet potatoes are planted and wheat fields are used. Thus, the area's ume cultivation is gradually forgotten and only slightly done. On the other hand, because there are few paddy fields and many slopes in the villages in the valley : 1955s Cultivation of persimmon and pears is flourishing, centering on mandarin orange. Most of the farmer's income has been supported by mandarin orange cultivation. Daylight hours per day-It is shorter and the temperature is lower than the plains-It could not be said that the conditions were favorable compared to other production areas in terms of cultivation. From there, we got on the nationwide production Boom. 1965s The prefecture's production has risen from 2 million tons to 3 million tons. However, in 1967, a price plunge occurred. Because of this, it was judged that it would be difficult to survive in the competition between production areas. Then, from this time, the conversion to plum cultivation was carried out. “Nanaore Koume”, From light green to yellowish and clear shine as it matures. The feature is that there is no variation in maturity. “Blue diamond” also go by the name of because of its high quality-It has been cultivated since around 1900 and used to be traded at high prices. We worked on the cultivation of high quality plums while consulting with the Tokushima Agricultural Experiment Station. Currently, various processed products such as plum wine are also on sale. “Dried plum” regulates the action of angiotensin II(Asp - Arg - Val - Tyr - Ile - His - Pro - Phe - OH), a hormone with a vasoconstrictive effect. Expected to have the effect of suppressing the rise in blood pressure and suppressing the occurrence of arteriosclerosis. “Kreb's Cycle”, Energy sources such as sugars and lipids ingested as food : It is digested in the body and converted to charcoal glucose. Citric acid → aconitic acid → isocitric acid, Ogizaro succinic acid → alpha keto-glutaric acid → succinic acid, Converted from furic acid → malic acid → Oxaloacetate. Also, to citric acid again. Oxidatively decomposes fever glucose while changing to several acids and releases it as energy.
