In particular, the taste (sugar content), size, color, shape, etc. are all sorted by an optical sensor so that we can deliver the highest quality peaches. In addition, the peaches that have been thoroughly worked on, such as introducing soil preparation with a production method using low chemical fertilizers and reduced pesticides, and all of them have obtained “Eco Farmer” certification from the Governor of Yamanashi Prefecture, are called “Kasugai brand peaches”. Called and famous.
The optical sensor sorting uses near-infrared spectroscopy. Simply put, it is a method of shining near-infrared rays on a fruit and measuring how the light is absorbed to measure the sugar content and water content of the fruit. Near-infrared spectroscopy (NIRS) is a noninvasive technology that continuously monitors regional tissue oxygenation. Originally used for assessment of oxygen saturation of the brain, its use has now been expanded to evaluation of oxygenation of tissues other than There is also growing evidence for the larger applicability of NIRS as an estimate of systemic venous saturation in correspondence with the adequacy of the circulatory status. New and promising advances may further this technology to become part of our standard armamentarium, in order to optimize patient care in daily anesthesia practice.
Compared to other production areas, the price is 20 to 30% higher, and it is highly evaluated by the market as a brand production area. The history of peach cultivation in the Kasugai district of Fuefuki City, Yamanashi Prefecture is old and dates back to the Taisho era. Even though peach cultivation became popular before World War II, the decree on planting control during the war (in November 1941, just before the start of the Pacific War, the prefecture implemented agricultural land planting control based on national policy, that is, on flat land. The peaches were cut down by cutting down the cultivated mulberry and fruit trees and converting them into major food crops such as wheat and potatoes), and once disappeared. It gradually revived from around 1950, and in 1961, with the introduction of hand-packed boxed fruit selection, which can be called craftsmanship, it gained the trust of the market and suddenly became known as “Japan’s No. 1 peach is Kasugai”. In the old days, it seems that the farmers themselves packed the peaches in boxes using artistic techniques, not only sticking to the shape, but also using a brush to trim the peaches.
