Raised in the great land of Miyazaki — a brand pork where the sweetness of satsumaimo melts into every single bite.
Hyuga Osatsu Pork is a brand pork carefully raised at a company-owned farm in the mountains of Miyakonojo City, Miyazaki Prefecture. The defining characteristic is blending kansho meal derived from domestically-produced sweet potato into the feed in the finishing fattening period. A feed carefully dried and processed from sweet potato trimmings born in the manufacturing process of southern Kyushu’s imo-shochu and karinto confections — given to the pigs for 60 or more days before shipping. The high-quality starch and dietary fiber richly contained in sweet potato — while appropriately suppressing excessive fat accumulation — slowly draws out the inherent sweetness and umami of the meat. The breed is a three-breed cross pig of Landrace, Large Yorkshire, and Duroc. While thoroughly maintaining strict hygiene management — raised spaciously and without stress — healthy, stable-quality pork is born. Also in component analysis — confirmed to be soft pork richly containing umami components and high-quality fat compared to standard domestic pork. The elegant sweetness spreading from the moment it enters the mouth and the clean aftertaste woven with the faint sweetness derived from sweet potato captivates those who eat it. The non-gamey, unaffected flavor demonstrates true value not only in simple salt-grilling and stir-fry but also in slowly braised preparations. In pork kakuni (braised pork belly) and hamburger steak — the sweetness and umami unique to the ingredient produces an exceptional flavor. Managing entity Nangoku Kosan Co., Ltd. practices resource-circulating agriculture re-utilizing food manufacturing by-products as feed — the stance of sustainable livestock farming with environmental consideration is highly evaluated.
