1. When was instant coffee invented?

The origin place of coffee is Ethiopia, before being introduced to Europe in the 17th century, it has been used as a beverage in North Africa and West Asia for hundreds of years. There are various coffee plantations in all hot and humid regions of the world, and coffee has become a popular beverage. But if you want to make a pot of delicious coffee, the making process is very complicated. Coffee beans must be ground into a fine powder, then use a filter to keep the coffee grounds out of the cup.

Coffee Plantation

The complicated steps of making coffee inspire inventors to find an easy way to make a cup of coffee. The concept of “coffee compound material” first appeared not in the United States, but in the United Kingdom around 1771. However, due to the difficulty of its storage, the aroma will soon deteriorate, and the coffee can no longer be drunk. Therefore, its instant production method is only short-lived in history. As a result, there was no patent application and commercialization at that time.

The First Person To Apply For A Patent For The Production Method Of Instant Coffee-Japanese Satori Kato

Until 1853, before the Civil War, the Americans once again challenged the production of instant coffee, turning powdered coffee into solids, but the problem of coffee preservation still could not be solved, so the market for instant coffee was not good. Japanese chemist Kato Satori, who worked as a chemistry expert in Chicago, USA, once studied instant green tea, so some coffee importers and roasters found him, asked him to find a way to remove the moisture in the coffee.

Kato worked with some American chemists to develop a feasible method, the brewed liquid coffee is made as a dry powder after vacuum-dried, and the coffee concentrate is made. On April 17, 1901, Sato submitted a patent application to the United States, the application has elaborated on the problem of coffee preservation and the solution. On August 11, 1903, Kato obtained the “No. 735777” patent for “Coffee Concentrate and Its Making Process”. When he got the patent, Satori Kato didn’t realize that instant coffee could be commercialized.

Coffee Making Process

The First Person To Obtain A Patent For The Large-Scale Production Process Of Instant Coffee-American George Constant Louis Washington

In 1909, George Washington invented the technology for mass production of instant coffee and began the mass production of “Red E Coffee” and sold it to the market. Soon after, the First World War broke out in 1914, U.S. Secretary of the Navy Josephs Daniels gave the navy an order to ban alcohol. Although instant coffee did not taste very good at that time, due to the convenience of instant coffee, coffee became a substitute for alcohol, and soon occupied the mainstream beverage status in the navy, coffee became one of the armaments purchased by the U.S. military. But the technology at that time was backward and could not be preserved well, so instant coffee has not been spread all over the world.

The Company That Truly Spreads and Commercializes Instant Coffee All Over The World – Nestlé

By 1930, the Brazilian Coffee Association and the Swiss “Nescafe” company negotiated and asked them to try to produce a soluble coffee beverage to help solve the problem of overcapacity of Brazilian coffee beans, Nestlé spent 8 years make the research. In 1937, Nestlé successfully invented instant coffee with higher quality and better taste through the spray drying method. In 1938, instant coffee made by spray drying was named after “Nescafé” and sold. During the Second World War, “Nescafé coffee” was used as a munition for the U.S. Army, and spread all over the world after the war, letting people all over the world know about the existence of instant coffee.

2. Is instant coffee bad for you?

More than half of the coffee beans in the world are used to produce instant coffee. Fast-paced life makes instant coffee beverages more and more popular. But some people are unfamiliar with the recipe and production process of instant coffee, they think that instant coffee is harmful to their health. But for food, it is meaningful to evaluate whether a beverage is healthy only through scientific analysis of nutrition and ingredients. Not all instant coffee is unhealthy, it mainly depends on what ingredients are in the coffee ingredient list.

In order to retain the flavor of coffee beans as much as possible, low-temperature extraction, freeze-drying, and instant soluble coffee production processes are more popular nowadays. But in the mass production process, from baking to extraction to drying, the aromatic substances contained in coffee beans are still unavoidably lost. Some coffee manufacturers add creamer, flavor, acrylamide, sugar, etc. to enrich the taste of instant coffee. Instant coffee containing non-dairy creamer, flavor, acrylamide, sugar, and other chemical ingredients is harmful to the health.

3. Specialty instant coffee is a new growth point in the instant coffee market

There are two types of instant coffee on the market, one is pure black coffee, the other is two-in-one or three-in-one coffee with coffee-mate or sugar added. Black coffee has a mellow taste, low caffeine content, natural formula, but a slightly bitter taste.

If you have the conditions or time, we suggest you drink freshly ground coffee with fresh coffee beans, this is the healthiest way to drink coffee. But if you don’t have the time and energy to make a cup of coffee every day, you can choose the more popular high-quality specialty instant black coffee. The ingredient list of this kind of coffee only contains coffee beans.

The specialty instant black coffee is a new type of instant coffee that has become popular in recent years, this kind of coffee is made by the freeze-drying method and no longer uses a high-temperature extraction method. Instead, use a low temperature to remove the water, which can better maintain the aroma of the coffee itself, and there is no need to add other chemical spices.

At present, most specialty instant coffees use Arabica beans as raw materials. Compared with Robusta, Arabica has better quality, better aroma, and flavor, and lower caffeine content, which makes it easier to accept black coffee for people.

High Quality Granular Black Instant Coffee

According to statistics from the International Coffee Organization, China’s coffee consumption is growing at an annual rate of about 15%, which is much higher than the global average growth rate of 2%. It is estimated that China will become a trillion-level coffee consumption superpower by 2025.

Compared with other types of coffee consumed at home, instant coffee still occupies an important position in the Chinese coffee market. However, instant coffee is losing consumer’s interest and its market share, because consumption has been upgraded to higher-quality coffee types, the consumption upgrade problem faced by instant coffee is inevitable.

In view of the slow growth of instant coffee, coffee companies and manufacturers are turning their focus to other coffee categories, such as ready-to-drink coffee or capsule coffee. However, the instant coffee category still has a chance to regain consumer attention.

The image of fresh coffee in the minds of consumers is higher quality and more fashionable, while instant coffee is considered a cheap, low-quality choice, and at the same time, it is also considered unhealthy because of its additives. In order to get rid of the image of no quality and only a convenient coffee choice, the instant coffee category needs to incorporate high-end factors in the promotion of new products.

Companies and manufacturers can focus on promoting the use of high-quality coffee beans, more details about the coffee beans’ growth environment or production process, not just their origin places. Instant coffee producers can associate products with more fashionable concepts, such as cold brew or micro-ground coffee. These strategies have been adopted by some instant coffee brands around the world, such as Nescafe’s Gold series and the AZERA series.

4. Why is freeze-dried instant black coffee often packaged in glass bottles?

In the early days, most instant coffees used steam-drying technology to evaporate water and process it into fine particles through distillation. As the moisture evaporates, part of the aroma of the coffee is taken away, therefore, sugar or other additives are usually added to increase the taste of coffee.

Freeze-drying technology is to make coffee freeze into ice rapidly in a low-temperature environment of tens of degrees below zero, then the ice is converted into vapor to remove under a higher vacuum, finally, it becomes the form of large particles. Since the drying process is carried out under low temperature and high vacuum, the aromatic substances with strong heat sensitivity are retained.

Therefore, freeze-dried instant coffee can retain more of the original coffee flavor, with a strong aroma and pure taste, most of them will not add sugar, non-dairy creamer, and other additives. Due to the cumbersome production process, the price of freeze-dried coffee is slightly higher than ordinary instant coffee, but the original flavor of coffee is better retained.

Freeze-Dried Instant Coffee

Instant coffee particles are hygroscopic, in other words, they will absorb moisture in the air. Therefore, they must be packaged in moisture-proof containers under low humidity conditions to keep the products dry until consumers buy and open them. In addition, in order to prevent the loss of aroma and flavor, the coffee packaging process should be carried out in a low-oxygen atmosphere (usually carbon dioxide or nitrogen).

At present, the packaging of instant coffee shows a diversified trend, including glass, plastic, and metal. However, glass packaging is the first choice for many manufacturers to pack bigger specification specialty instant coffee. Glass packaging was first used in Egypt in 1500 BC, and it has a longer history of use than metal packaging and plastic packaging.

As more and more high-end instant coffee products seek differentiated packaging in their products, glass bottle packaging has become the first choice. Because glass bottles are selected for creating differentiated packaging, which determines that glass bottle packaging corresponds to a Niche market.

5. What kind of machine is used to package specialty instant coffee in glass bottle?

The premium instant coffee made by the freeze-dried method is in the form of granules, not powder. Therefore, this type of coffee must be filled by the granule filling machine. The granule packaging machine is used to pack granular materials with better fluidity into the packaging container according to the specific measurement requirements. The granular instant coffee in the glass bottle can be filled with a semi-automatic or automatic instant coffee packaging machine according to the different degrees of automation.
