Banana leaf

The banana leaf is the leaf of the banana plant, which may produce up to 40 leaves in a growing cycle. The leaves have a wide range of applications because they are large, flexible, waterproof and decorative. They are used for cooking, wrapping, and food-serving in a wide range of cuisines in tropical and subtropical areas. They are used for decorative and symbolic purposes in numerous Hindu and Buddhist ceremonies. In traditional home building in tropical areas, roofs and fences are made with dry banana-leaf thatch. Bananas and palm leaves were historically the primary writing surfaces in many nations of South and Southeast Asia.
Banana leaves are large, flexible, and waterproof. They impart an aroma to food that is cooked in or served on them; steaming with banana leaves imparts a subtle sweet flavor and aroma to the dish. The leaves are not themselves eaten and are discarded after the contents are consumed.
Besides adding flavor, the leaves keep juices in and protect food from burning, much as foil does. In Tamil Nadu (India) leaves are fully dried and used as packing material for foodstuffs, and are also made into cups to hold liquids. The dried leaves are called vāḻaic caruku (வாழைச் சருகு) in Tamil. Some South Indian, Filipino and Khmer recipes use banana leaves as a wrapper for frying. The leaves are later removed.

It also functions as a traditional disposable take-away food container. The cleaned banana leaf is often used as a placemat; cut banana-leaf sheets placed on rattan, bamboo or clay plates are used to serve food.

In India, white rice (or parboiled rice in authentic South Indian restaurants) is served on a banana leaf with an assortment of vegetables, pickles, appalam and other regional condiments (usually sour, salty or spicy). The banana leaf acts as a disposable plate and it in itself is not consumed. The choice of banana leaves is mainly due to the broad leaves as well as to the ubiquity of the plant in South India. Typically, only vegetarian gravy (e.g. sambar) will be served on the rice as it is meant to be a traditional vegetarian dish. However, sometimes boiled eggs, curried or fried meat or seafood are served as well. Traditionally, there will be two servings of rice with the first being served with gravy, side dishes and condiments whilst the second serving will be just rice with curd as a palate cleanser. Banana leaf meals are eaten by hand. Traditionally only the right hand is used, and only the tips of the fingers should touch the food. Any part of the finger beyond the first knuckle or the palm must not touch the food. Parts of the Banana leaf meal etiquette also dictates that, after the meal, the guest must always fold the banana leaf inwards as a sign of gratitude to the host, even when the host is the proprietor of an eatery. However, when meals are served at funeral wakes, the leaf is folded outwards as a sign of condolence to the family of the deceased. Due to this, folding the leaf outwards is considered rude in any other circumstance.

People believed that krathongs will carry their wickedness and bad luck, and after that happiness will come to them. It is a time joy and merrymaking, dancing, singing, and activities with other people. People use banana leaves to make krathongs because it is an organic and natural material, and would decompose easily in the water.
Banana and palm leaves were historically the primary writing surface in many nations of South and Southeast Asia. This has influenced the evolution of their scripts. The rounded letters of many of the scripts of southern India, Sri Lanka and Southeast Asia such as Oriya and Sinhala, Burmese, Baybayin, and Javanese, for example, are thought to have been influenced by this. Sharp angles and tracing straight lines along the vein of the leaf with a sharp writing implement would risk splitting the leaf and ruining the surface, so rounded letters, or letters with straight lines only in the vertical or diagonal direction, were required for practical daily use.
In such situations, the ribs of the leaves function as the dividing lines of ruled paper, separating lines of text. It is believed that this was so influential in the development of the still-undeciphered rongorongo script of Easter Island that the more elaborate wood tablets developed later were fluted to imitate the surface of a banana leaf.
The leaves contain apiin which is used to make nanoparticle products.
