Let's talk about the ingredients in milk tea!
What is the pearl in milk tea? Is coconut the flesh of coconut? How did Simi come from? Is fairy grass made of grass? In this article, let's talk about the ingredients in milk tea.
Pearl
Many people like to drink pearl milk tea. In fact, they mainly like the "pearls" with Q shells and chewiness. However, there are many sensational rumors about the "pearl" in pearl milk tea: some say it is made of plastic, some say it is made of old tires, and even say it is made of leather soles
In fact, the "pearl" in pearl milk tea is a food made with starch as the main raw material, also known as farina. Cassava starch is the most commonly used. Mix cassava starch, black sugar (or brown sugar) into dough, rub them into small balls, and then put them into boiling water to boil until they are transparent. The smooth "pearls" will be out of the oven. In order to have a better taste and chewiness, you can also add some wheat protein and food additives.
When it comes to pearls, we have to mention a food very similar to them - taro balls. Taro balls are similar to pearls, but the raw materials are different. Pearl is mainly made of cassava starch; The taro balls are mainly made of taro starch, together with sweet potato starch, purple potato starch or cassava starch. Different raw materials can be used to make taro balls of different kinds, and the colors are also rich.
Coconut
Coconut is a very popular tropical fruit. Open the coconut, drink the coconut water inside, and then break the coconut shell. The flesh inside can also be eaten directly. People who have eaten coconut meat know that coconut meat is soft and not as chewy as coconut in milk tea and other desserts. So, what is coconut?
In 1886, British scientist Brown found that a gel like film was formed on the surface of the culture medium when he was cultivating Acetobacter, and it was confirmed by analysis that it was cellulose, so it was called microbial cellulose or bacterial cellulose. In nature, there are many kinds of microorganisms that can produce cellulose, including Acetobacter, Rhizobium, Pseudomonas, Azotobacter, etc. Among them, Acetobacter has received the attention of many researchers because of its high cellulose yield and excellent cellulose characteristics, and is widely used as a template microorganism in the research of microbial cellulose synthesis. Nowadays, microbial cellulose has been prepared in batches and widely used in textile, medical, food and other fields. Because of its high water content and cellulose content, microbial cellulose has a smooth and chewy taste. Besides being used as dietary fiber food, it is also widely used in the food processing industry as a food additive.
Coconut is a kind of microbial cellulose, which is a milky white gel like substance formed on the surface of the culture liquid through the metabolism of bacteria with coconut water as the main raw material, also known as coconut gel. Therefore, coconut is actually a metabolite of bacteria, a kind of dietary fiber food. It is completely different from the natural pulp of coconut, and has little to do with coconut water.
However, it is said that in order to reduce the production cost of coconuts, the raw materials for cultivating bacterial cellulose are no longer coconut water, but artificially prepared culture solution at a lower price. If this is the case, then coconuts and coconuts are completely irrelevant.
Sago
Common rice in life, such as millet, rice, purple rice, black rice and job's tears, is directly harvested by planting crops. What is sago? Is it planted?
Sago, also known as sago rice, is not directly planted rice, but a processed starch product. authentic sago is processed from sago trees. The common sago palm trees in Malay Islands contain a lot of starch. Edible sago starch can be made by processing the core or soft core of sago palm trees, soaking, precipitating, and drying after mechanical treatment (pounding, grinding, milling). The sago starch is further processed into round granules, which are called raw sago. Before eating, boil the raw sago in boiling water for a period of time, and it will become our common crystal clear appearance.
Nowadays, many sago on the market are not authentic sago made from sago starch, but starch extracted from beans and potatoes with low cost, among which cassava starch is the most common.
magic herb
The fairy grass in milk tea and desserts is actually the jelly of fairy grass, which is a kind of black jelly like food. So what is the relationship between immortal jelly and immortal grass? Is there really "fairy grass"? Is the jelly made of grass?
In fact, there is really a kind of plant called Xiancao, also called Xianren Grass, Liangfen Grass and Xianren Jelly. Although it can not be eaten directly, it is a kind of plant used for both medicine and food, from which a variety of effective ingredients can be extracted and used in food, health products, medicine and other fields. One of the important substances is Xiancao gum, which is widely found in the leaves, roots and stems of Xiancao, and the content of Xiancao leaves is the most abundant. Xiancao gum has good gel property and better thermal stability than general food gum. It can be used in the production of jelly to improve the elasticity, toughness and chewiness of the product, making its taste more tender and smooth, and its flavor more unique. Xiancao gum is also the key material for preparing Xiancao jelly.
