A name that was originally registered as a trademark for “Beniharuka Sweet Potato”, which has the same sweetness as Anno Sweet Potato, produced by JA Namegata Sweet Potato Group in Ibaraki Prefecture. It was named for its gentle sweetness and moist taste.
【主な特徴】
As a verification of the measures taken so far, Namegata City in Ibaraki Prefecture has defined areas where it is deemed necessary to promote agriculture based on the Law Concerning the Development of Agricultural Promotion Areas. In relation to the Agricultural Management Base Strengthening Promotion Act, the Namegata City Agricultural Economics Act will take measures such as concentrating the use of agricultural land for motivated farmers and streamlining the management of these farmers. In September 2020, the “Basic Concept for Promoting Strengthening of Business Infrastructure” was formulated. In addition, in order to differentiate from other production areas, to produce agricultural and marine products with high commercial value that are recognized by consumers and actual users, and to establish sales promotion and branding of regional specialties centered on agricultural and marine products. "Namegata City Sixth Industrialization Promotion Plan 2018-2022" was formulated in March 2018 as a guideline to promote the sixth industrialization comprehensively and systematically. Seems to be. In 2016, the JA Namegata Shiosai Sweet Potato Subcommittee Liaison Committee won the Grand Prize at the Japan Agricultural Award, which recognizes organizations that contribute to technological and management reforms in agriculture and the development of local communities. Also, in 2017, he won the Emperor's Cup at the "56th Agriculture, Forestry and Fisheries Festival", which is selected and awarded from nationwide awards, mutual encouragement, competitions, etc. As a production area that sparked the roasted sweet potato boom and provides delicious sweet potatoes 365 days a year (24 hours out of 24), it has been highly evaluated by the market and distributors. , Thailand, Hong Kong, Singapore, Canada, France and Germany. It has also contributed greatly to the increase in demand for Japanese roasted sweet potatoes overseas. Going back to the past, it seems that charcoal was placed in a waist-high jar and the air inside the jar was heated to heat the fried in the conch method, which was introduced from China. Ishiyaki-imo, which is baked on stones heated in a kiln, is said to have been invented by Manzo Minowa, who originally ran a ramen shop called 'Chinrai' in 1951 after the war. From the Edo period to before the Pacific War, most of the sweet potatoes in Edo and Tokyo were used for baked sweet potatoes. Therefore, its distribution was special. It seems that the potatoes from the production area did not go through the fruit and vegetable market, but went directly to the wholesalers scattered in various places. The wholesaler took it down to a roasted sweet potato shop. It seems that he also baked and sold it at his own shop. However, sweet potato wholesalers are disappearing as they gradually become out of step with the times. At that time, there were 73 sweet potato wholesalers in Tokyo. It seems that the husbands were recruited as inspectors for the newly established Sweet Potato Control Company. The reason the control over sweet potatoes was lifted was because the post-war food situation was finally improving. It seems that it has been since 1950. Appear as if you were waiting for it. It seems that it was a stone baked potato. It seems that it was a new method that had never existed before, baking sweet potatoes using pebbles, and loading the tools for that on a cart and moving around the outdoors. I heard that it was so popular that most of the baked sweet potato shops in Tokyo after the war became it. However, the number of sweet potato wholesalers decreased sharply. After 10 years of hiatus, only about 20 restaurants were able to reopen. There is a god of water in Mukojima, Sumida, Tokyo. There was a field next to it, and Minowa's house was said to be next to it. He was the clerk of a group of ramen shops called 'Chinrai'. I don't know why such a person thought of stone-baked potatoes. The cart for it is not ordinary. It was a big, sturdy thing custom-made by an ironworks. At first, he went out into the town and sold it, but eventually he had a salesperson and became a master who had them sell it. Stone-roasted potatoes can cook a large amount in a short time compared to the pot-baked method that was used until then. In addition, Manzo used his experience at a ramen shop in his previous job to sell a set of tools for making stone-baked sweet potatoes on a cart. It seems. Until around the Showa period, it was popular as the last fun of burning dead leaves on a cold winter day. Beniyuka Sweet Potato is a trademark registered by the Patent Office for products produced by the JA Namegata Sweet Potato Group. "Beniharuka sweet potato: Kansho Norin No. 64'', which has the same sweetness as Anno sweet potato. This is a crossbreeding of "Harukogane sweet potato" as the father, and was bred at the Kyushu Okinawa Agricultural Research Center of the National Agriculture and Food Research Organization. The applicant for registration of the variety was selected by the National Agriculture and Food Research Organization. In 2011, the Namegata Agricultural Cooperative applied for registration of "Beniyuka sweet potato'' based on the Patent Office trademark registration system, and it was registered in 2012 (Beniyuka, etc.: registration 5474614). "Vitamin B1" is a chemical compound scientifically named "Thiamine" and is a nutrient necessary for converting glucose into energy. "Vitamin B1" consists of thiamine and one phosphoric acid. There are "thiamine monophosphate: TMP'' that is linked, "thiamine diphosphate: TDP'' that is linked with two, and "thiamine triphosphate: TTP'' that is linked three. , It seems that a lot of vitamin B1 is required because energy consumption is thriving. The amount of "maltose'' produced in steamed "sweet potato'' increases with the "β-amylase'' activity of tuberous roots, but the increase is suppressed when the activity exceeds a certain value. It seems. Beniyuka sweet potato and Beniharuka sweet potato both boast a high sugar content of around 40% compared to other sweet potatoes. It is said that this sugar content is further increased by making roasted sweet potato, reaching over 50-55 degrees. Even Anno sweet potato, whose sweetness has been a hot topic for a while, has a sugar content of about 40 degrees when it is roasted sweet potato. I can understand that it is a plant. Traditional Anno sweet potatoes are cultivated on Tanegashima Island, Kagoshima Prefecture mainly in the Anno area. The surprising sweetness and the sticky texture are very popular. In 1989, he started to select and cultivate excellent varieties at the Kagoshima Prefecture Agriculture Development Center Kumage branch. The variety will be registered in 1998. One sweet potato brought back by a soldier from the area of Seldan in the northern part of Sumatra after World War II is cultivated on the island. It has a sweet, moist and smooth taste, and contains more C12H22O11（sucrose: 蔗糖）than others. From the taste, I hear that it contains a lot of polysaccharides contained in okra（Abelmoschus esculentus）and yam（Dioscorea japonica）. Suitable temperature for storage is 13 ℃ ~ 15 ℃. It may be damaged at low temperatures, so be careful not to dry it too much. For long-term storage, it is recommended to roast sweet potatoes before freezing. Going back in time, it is said that after trial and error, the cultivation was successful for the first time in Japan. It will spread all over Japan as a savior of food shortages. Did my ancestors also cultivate the fields and endure the food shortage? Seven years ago, it was cultivated by Riemon Maeda of Ibusuki City Yamakawa. 37 years ago, it was cultivated by Konyo Aoki at the herb garden in Koishikawa, Edo. 1698 19th island owner Hisamoto Tanegashima-鶴袈裟丸; Afforestation, salt production, newly reclaimed rice field development, iron making, etc., as well as education, etc., Natural elements sagacity a rarely seen great material, devoted himself to island politics as his father's name from early on, and endured wisdom. Merged on February 1, 2019. The jurisdiction is located in the southeastern part of the prefecture, sandwiched between Kasumigaura, Kitaura, and Kashima Nada, and has a peninsular topography. Fertile upland fields are called "water towns" on the whereabouts plateau and Kashima plateau, and paddy fields spread on the shores of both lakes. Namegata City is a city that was born by the merger of Aso Town, Kitaura Town, and Tamatsukuri Town in 2005. The reading of the city name "Namegata (whereabouts)" was solicited from the citizens, "I have a history and culture that I have become accustomed to as a county name, and I want to pass it on to the future." It was selected for reasons such as "there is a traditional weight such as" and "the reading of the name (whereabouts) is based on the name of the current county name". It is said that the origin of Namegata is that "Yamato Takeru no Mikoto" used the expression "NAMEKUWASHI" to describe the intricate state of the waterside and plateau of Namegata City. I will explain the details later, but first I will briefly explain the product. "Benikogane sweet potato", It will change moistly during the year by storing it for a long time. “Ferment Benikogane sweet potato”, Especially as sweet potatoes that have been stored for a long time, they are very sweet and have a rich flavor that is soft even when cooled. “Curing low temperature storage”, The temperature is 13 degrees and the humidity is close to 90%, so it does not give stress as much as possible. Connect to consumers with this thorough management. According to a survey, you can enjoy it from May to August. "Nameri Micotto" is a mascot character that was born in 2013 (March 2013) by public recruitment nationwide. "Namegata" and "Yuri" have the surname "Nameri", an ancient noble image. The name is "Mikot" because the traditions of "Noble" and "Yamato Takeru no Mikoto" are also preserved. In 2021, Namegata City, which is full of history, received a total of 247.73 million yen for the Hometown tax (The concept of hometown tax donation program is actually to support the development of small or less-funded municipalities.). It seems. It was successful to increase the registration of the site dealing with this tax to four. There are eight registered sites in 2022, and it seems that they want to increase the number of registrations in the future. Kashima City has also indicated its policy of aiming to increase revenues by accepting hometown tax donations, and efforts to increase the amount of donations received are expected to become more active in various places. Hometown tax started in May 2008 due to the revision of the local tax law in April 2008. Although "Hometown" is used in the name, taxpayers actually donate to prefectures and municipalities they want to support, and local governments send gifts according to the amount. Although it varies depending on conditions such as income and family composition, the portion of the donation amount exceeding 2,000 yen can be deducted from income tax and resident tax. According to a survey by Japan's Ministry of Internal Affairs and Communications, the amount accepted by Namegata City in fiscal 2021 will increase by 56.03 million yen compared to fiscal 2020. It seems that the amount of increase was the top among the five deer cities. The other four cities received 283.29 million yen (up 29.62 million yen) in Kashima City, 180.86 million yen (up 30.10 million yen) in Itako City, and 113.05 million yen (up 30.10 million yen) in Kamisu City. 28.12 million yen decrease), Hokota city: 176.89 million yen (41.71 million yen increase). The Business Promotion Division of Namegata City plans to increase the number of registered sites to 12 by the end of this year. Kashima City also indicated its intention to work on measures to increase the amount of acceptance at the regular meeting of the city council that opened on August 31 of the same year. In the Rokko5 cities, rice, dried sweet potatoes, pork, vegetables, and other foodstuffs are popular, probably because the demand for stay-at-home has increased after the spread of the new coronavirus. In the city, for farmers, "Pleunodomus destruens (a fungus (a type of mold)) is a disease that mainly infects sweet potatoes (convolvulaceae only). When infected, the stems at the ground part of the sweet potato turn black, As the symptoms progress, the leaves and stems wither and die, and then the tubers (potatoes) rot. Compared to other diseases, the infectivity is stronger, and the damage spreads in a short period of time. Infected tubers (seed potatoes) and infected seedlings invade fields, and spores formed on infected plants spread to healthy surroundings due to rainfall and stagnant water in fields. It seems that the sweet potato is infected and the disease spreads. In the field where the disease occurred in the previous sweet potato cultivation, if the infected residue remains without being decomposed, it will become a source of infection for the next crop." In order to prevent the intrusion of pests, detect suspicious strains at an early stage, and prevent the spread of pests, it is important to thoroughly implement prompt control measures. For this reason, it is recommended to check whether the stems are dead or yellowed or whether the stems at the ground are blackened before harvesting. Also, when harvesting, check to see if the sweet potato vines have turned black, if the tubers have sprouted, or if they have rotted. If you find a strain that is suspected of having this disease, do not remove it, mark it so that you can see where it was found, and leave it as it is so that the pathogen does not spread to the surroundings. In addition, if a tuber suspected of having this disease is found after harvesting, store it in a plastic bag and separate the container containing the tuber from the container containing healthy tubes. Also, if you find a plant or tuber suspected of this disease, we recommend that you contact the management and extension department of the Rokko Agricultural and Forestry Office (or the Namegata Regional Agricultural Improvement and Extension Center) immediately.
It contains a lot of maltose, and the sweetness of starch syrup is impressive. At the JA Namegata Sweet Potato Section, 3 varieties of sweet potatoes are being shipped in relay, Beniyuka Sweet Potatoes from August, Benimasari Sweet Potatoes from November, and Benikogane Sweet Potatoes from April. It seems that each type of sweet potato is cultivated and shipped considering the best season for it, but it is this excellent agricultural product that takes the top spot.
According to the Namegata Brand Strategy Council, the namegata plateau is a sweet potato field of about 1,000 hectares. In summer, the landscape of lush potato leaves seems to spread. In the past, it was cultivated as a raw material for starch, but it seems that around 1976, it began to be cultivated for raw consumption. The namegata plateau is a sloping field of red soil, and the well-drained and low-nitrogen soil is said to be suitable conditions for growing delicious sweet potatoes. When cultivation for eating raw began, Kintoki was the mainstream, but in the latter half of the 1975s, the Beniazuma sweet potato (Benikogane sweet potato), which has a good taste, a large yield, and grows well, began to be cultivated, and the number of farmers increased. seems to have increased dramatically. Currently, there are more than 350 farms producing sweet potatoes, most of which grow sweet potatoes in fields of about 5 to 10 hectares. It is said that about 20 tons of sweet potatoes are harvested per hectare, and some farmers produce more than 100 tons per year.
Sweet potatoes are a crop that requires quality control in winter. After harvesting, the sweet potatoes are heat-treated at around 32°C to seal the damage at the time of harvesting, and are rapidly refrigerated for curing (after harvesting, sweet potatoes with soil attached are placed in an environment of 35°C and humidity of 95% or more for about 50 hours. , A cork layer is formed in the subcutaneous tissue, which naturally heals the wounds made during harvesting. This is called curing treatment, which prevents the invasion of pathogenic bacteria and locks in optimal moisture and taste. After that, the temperature is lowered to 12°C at once and the humidity is By storing at 85%, the best condition can be maintained for a long time), and by constant temperature storage at about 12°C, shipment throughout the year is possible. Distribution to distant places from Japan to Canada and Thailand is also realized. It seems that local farmers are actively working to improve the quality and taste of their products, such as by constructing these facilities through joint ventures. The sales method is also considered by the farmers, the shipping companies, and the market.
