Nagaimo is a type of yam belonging to the Dioscoreaceae family. Due to its high water content, it is less sticky, and when grated, it becomes a smooth, grated yam that mixes well with other ingredients. This excellent produce is characterized by two seasons between autumn and early spring. From early November to December, the fresh autumn harvest is harvested, and from March to April, the richly flavored spring harvest is harvested, making our hearts dance.
The obligation to indicate the best-before date is determined by whether the food is “produced food” or “processed food”. An important item that consumers check when purchasing food is the use-by date and expiration date of the food. Japan’s Ministry of Health, Labor and Welfare and Ministry of Agriculture, Forestry and Fisheries have formulated “Guidelines for Setting Food Expiration Dates (Expiration Dates and Expiration Dates)”, stating that it is necessary to set deadlines based on objective items (indicators). there is I’ve heard that even if the yam is vacuum-packed, it’s treated as a vegetable, so you don’t have to put an expiration date on it. Since it is a root vegetable, it can be kept for a relatively long time, and it seems that it can be kept fresh for about two weeks after purchase whether it is a single stalk, packed in a normal pack, or vacuum packed.
There are many types of yamanoimo, and they all seem to be a kind of taro, which is considered a sacred food by the people of Southeast Asia and Polynesia. It is a traditional vegetable that has been cultivated in the Japanese archipelago since the Jomon period, and is an excellent ingredient suitable for nourishment and tonic. In English, yamanoimo in general is called “Yam”, but it is also pronounced “Yummy”, which means “delicious!” It is also said that Yum is the sacred corn god that was the foundation of the Mayan civilization. Almost 3,000 years ago, the ancient Maya created a great civilization that still shows little influence. As you all know, the Maya civilization flourished in the Mesoamerican region centering on the Yucatan Peninsula, such as Mexico, Guatemala, and Belize. Why did the highly developed and glorious ancient Maya civilization suddenly disappear in such a short period of time 1,200 years ago? At the same time, it reminds us that humans are completely powerless against the wrath of nature. Around 2000 BC, urban development occurred in the Maya region, and it seems that the earthenware culture, which had been local until then, spread rapidly. This was the beginning of the Mayan civilization, which prospered in various forms until the 1500s. By the way, Japan’s advanced civilization began to develop in the 700s BC in the Jomon period, so it must have developed quite early. The Maya region is divided into three regions: the tropical rainforest lowlands in the south, the savannah lowlands in the north, and the cold Maya highlands. Although each was placed in a different harsh environment, many small cities existed and formed a civilization, and it is strange that a unified nation like Asia was not born.
