Introduction:

Sugar maple, Acer saccharum Marsh, belongs to Acer of Aceraceae. Deciduous trees. Also known as sugar maple. Native to North America. The stem is more than ten meters high, the leaves are three-pronged or five-pronged, white hairs are born below, the flowers are yellow-green, and there are no petals. The fruit is similar to that of ordinary maple trees. The sap flowing from the trunk can be used to make sugar. The juice is concentrated into syrup for eating or re-cooked into granulated sugar. Every liter of juice can be made into 1. 1kg syrup, which has special flavor and is often used to make candied fruit, candy or tobacco for seasoning. The juice is a colorless and flowable solution, containing sugar and various acids and salts. The syrup is yellow-brown, the lightest is high-grade, and the thicker the color, the lower the grade.

Morphological characteristics:

Sugar maple is a deciduous tree, with a height of 25 to 35 meters and a maximum height of 45 meters. A ten-year-old sugar maple is about 5 meters high. The sap used to make maple syrup is transparent (non-turbid milky white), which can be compared with Norwegian maple with similar appearance. (Acer? platanoides,? Norway? maple)? Identify). The leaves are about equal in length and width, 8 to 15 cm long, and are five-lobed. When the central lobe is quite large and the lobe is extremely deep, the lobe near the base will become quite small. Autumn leaves are very conspicuous, with colors ranging from bright yellow and orange to bright orange. And the color change in autumn often presents uneven color distribution. Mature old trees often change color earlier than other plants, while young trees often change from green to brown and then lose their leaves. About 5 to 10 flowers form a corymb, and the flowers have no petals. Bloom in early spring. The fruit is samara (a detached fruit with two wings), the seeds are spherical, the diameter is about 7 to 10 mm, the film-like wings are about 2 to 3 cm long and mature in autumn. Sugar maple and Black maple (black? maple,? Acer? Black maple is closely related, and some taxonomists will classify black maple into this species. Bigtooth maple (bigtooth? Maple,? Acer? Grandidentatum) is also often classified into this species by some taxonomists and becomes a variety of this species.

Classification:

Maple syrup can be divided into several kinds with different sugar content, so its uses are different: some are suitable for making hard candy and cream, some are suitable for direct consumption, and some are suitable for cooking. In fact, maple syrup has many uses in cooking, but it is not well known. Foie gras with maple syrup is a favorite food of experts. There are many maple syrup products, such as maple syrup butter, maple syrup jelly (it smells fragrant and is very suitable for baking bread, and a little cheese is better), hard candy, sugar, mustard sauce with maple syrup, maple syrup jam, cotton candy and so on.
