![]() ![]() Setsuko says it brings her joy when she hears people say how delicious they are. Each one is handmade because Setsuko takes pride in the work she does and giving customers a taste experience they will always remember. She chooses tempura batter because she adds a bit of sugar to add some sweetness. She, and others who help her gather leaves that have fallen to the ground, packs them with salt and lets them sit for one year. In the summer of 2017 I learned of a woman in Japan who ventures out every autumn to gather hundreds if not thousands of maple leaves.įor over five decades, Setsuko Hisakuni has been making maple leaf tempura using yellow maple leaves because she says the veins are soft.er than other maple leaves. (Always remember that too much of a good thing can be a bad thing as well.) Deep Fried Maple Leaves Tannins from many maple species can be beneficial to our health when consumed in reasonable amounts. In 1922, Perkin isolated the first tannin from the Amur maple, but its structure was not determined until 1980. Early studies have shown that many species of this genus are rich in tannins. TanninsĪ total of forty-one tannins have been identified from this genus. ![]() They exhibit strong inhibitory activity against HIV-1 integrase.Īmong these flavonoids, the anthocyanidins are responsible for the colour change of leaves in spring and in autumn. Many flavonoid glycosides containing galloyl have been isolated from the leaves of: Acer tataricum subsp.ginnala (amur maple), Acer rubrum (red maple), and Acer platanoides (Norway maple). Flavonol, anthocyanidins, and flavones represent the main types of flavonoids in many maple trees, mainly in the form of glycosides. To date, sixty-two flavonoids have been isolated from the leaves and/or the stems of several maple species this accounts for about one-fifth of the total compounds. ![]() The compounds and extracts from these have exhibited a broad spectrum of biological and pharmacological activities, including antioxidant, anti-tumor, antimicrobial, anti-inflammatory, anti-diabetic, and hepatoprotective activities (protects the liver). However, the traditional uses of maples have been recorded primarily in local herbal books or have been orally passed down from one generation to another.Īn incredible 331 compounds have been identified from thirty-four maple species. Over the years, medicinal values of the maple genus have been shown to detoxify, treat rheumatism, bruises, eye disease, and pain. Several maple species have been used in traditional medicine in East Asia (China, Japan, and Korea) and North America, such as Acer negundo, Acer pensylvanicum, Acer rubrum, Acer saccharinum, and Acer tegmentosum. Recently, the seed oil of certain maple species, such as the Norway maple ( Acer platanoides) and the sycamore maple ( Acer pseudoplatanus), was found to be a good source of gamma-linolenic acid, a dietary supplement beneficial in treating a wide variety of human diseases, including cardiovascular diseases and cancer. Many maple varieties have been found to contain a large number of phytochemicals and several beneficial properties such as antioxidant, anti-tumor, and anti-inflammatory activities. The chemical composition and pharmacological activities of this genus have been studied for years by many researchers. The leaves of many maple species are not only edible, but healthy for us. It is obtained from the sap collected from certain Acer species, such as the sugar maple ( Acer saccharum), the black maple ( Acer nigrum), and the red maple ( Acer rubrum). Maple syrup, which is native to North America, has been historically used as a natural sweetener the world over. They are commonly used in commercial products, such as furniture and lumber. Maple trees have many uses from being ornamental to being a valuable source of food and medicine. ![]()
