It is a vegetable rich in umami and richness, rich in the ingredient C4H7NO4 found in asparagus, which is an excellent agricultural product. Hakama (triangular part on the stem) and the skin near the hard root can be peeled off with a peeler to make it beautiful and palatable. The part that snaps by holding the root of the stem is a guideline for the part with few streaks. When boiling, you can reduce the outflow of umami and nutrients by boiling it for a long time without cutting it. You can enjoy the refreshing aroma and natural sweetness by adding salt to a little hot water and steaming for several tens of seconds. Asparagus grows on rhizomes like japanese ginger, not plants that sow seeds and grow seedlings every year like japanese white radish and spinach. In the spring, the buds grow squishy, and every year, you can enjoy these young buds. After harvesting, the rhizomes are allowed to overwinter as they are, and it is customary to harvest and eat new shoots that will grow again in the spring of the following year. In recent years, the number of domestic products whose harvest period has been significantly extended is increasing due to green house cultivation.
This excellent produce grown in the sun is rich in vitamins. In particular, it contains a large amount of folic acid, so I recommend it to people who are anemic. At the tip of the ear, there are amino acids such as aspartic acid and C10H17N3O6S (a tripeptide consisting of three amino acids, which has an amide bond between the amino group of cysteine, which is rarely seen, and the carboxy group on the side chain side of glutamate). A kind is included. Aspartic acid seems to be effective in increasing metabolism and relieving fatigue. It also has the effect of excreting NH3 as urine, and can be expected to have the effect of preventing irritation and insomnia. In addition, it dilates peripheral blood vessels and lowers blood pressure, which will be very effective in improving hypertension and preventing arteriosclerosis. Glutathione has strong antioxidant power, and it seems that it can be expected to have a great effect of preventing aging such as wrinkles and sagging. Asparagus is said to have originated in Ukraine from Southern Europe. It has been cultivated since ancient Greek times and seems to have spread to Europe. It seems that it was introduced to Japan by the Dutch during the Edo period, mainly for viewing the leaves. As for food, I heard that cultivation began in Hokkaido during the Taisho era. Before the war, white asparagus for canning was the mainstream. Nowadays, with increasing health consciousness, green asparagus for raw consumption, which has high nutritional value, occupies most of the distribution.
Iwanai Town, Iwanai District, west of Hokkaido, is said to be the birthplace of asparagus. On the east side of Iwanai Welfare Hospital along Route 66, to the southwest of the intersection, there is a monument that says “The birthplace of Japanese asparagus.” Dr. Kikuzo Shimoda (1895-1970) will be very successful. In Iwanai at that time, the herring economy was booming, and he was the third son of a rice miscellaneous goods dealer. He entered the current Tokyo University of Pharmacy (Horinouchi, Hachioji City) with a false age of three, so he seems to have been a precocious person. After returning home, he gave instructions to farmers about chemical fertilizers, but it seems that he was often cried for the damage caused by cold weather. Without abandoning his ambition to produce crops that can withstand the frigid cold of Hokkaido, he searched for crops that are resistant to cold damage, discovered the native asparagus called “firefly grass”, and started cultivating asparagus. After many years of trial production, in 1922, it seems that the cultivation of this excellent agricultural product began in earnest in Japan for the first time in the sand dunes of 40 towns. Two years later, he established Japan Asparagus Co., Ltd. with the support of influential people. It seems that the canned white asparagus made in Iwanai eventually received higher praise than the imported canned food. In response to his desire to make asparagus, he gave guidance on cultivation to Kimobetsu, Abuta-gun in the early Showa period, and to Furano City after the war, and it seems that the asparagus fields have spread to various places.
