Why does food taste bland in space

So to improve the quality of airline food, airlines are beginning to experiment with testing meals in pressurised environments or aboard actual aircraft to replicate what passengers will experience. Our executive chefs have mastered the art and science of adapting recipes to changes in how food tastes at high altitudes. So far, this proves true mostly for meals in first and business class, though.

For First and Business class, Sky Chefs employ a team of executive chefs who work with airline customers — and use state-of-the-art kitchens, similar to those in a restaurant. Most meals are then placed in special carts and kept chilled until they are re-heated during the flight. Airlines keep finding better ways to research food preparation at altitude.

Singapore Airlines, for instance, works closely with their in-flight catering provider, SATS, which has a simulated aircraft cabin at their in-flight catering centre at Singapore Changi Airport, where meals are cooked and tested under low-pressure conditions.

Some of our senses, however, are unaffected by altitude, especially the so-called fifth taste, umami. It is the pleasantly savoury taste imparted by foods such as sardines, seaweed, mushrooms, tomatoes, and soy sauce. In a more radical approach, British celebrity chef Heston Blumenthal hoped to help British Airways deliver better in-flight food, by distributing nasal spray to passengers to clear their sinuses before they ate. That approach proved unpopular, though. So Blumenthal resorted to umami, for example with a recipe for shepherd's pie that featured seaweed in the crust.

History of Space Food In the early days of space flight, Mercury astronauts would consume puree squeezed from tubes and cubes of dry goods.

By Alaina On October 25, By Alaina On October 19, Due to lack of moisture, our sense of smell reduces and this affects our judgement on food taste.

At the same time, lower air pressure will also affect the sensitivity of our taste buds. As a result, our perception of saltiness and sweetness of food also drops. All these make food taste blander inside the cabin of a flying aircraft. Of course, caterers of in-flight meals would endeavour to enrich the flavour of their food served aloft in response.

When an astronaut chooses their meal, they scan a barcode found on the back of the meal's package. This allows their mission team to keep track of what they are eating. Aboard the ISS, a dining room with tables and chairs fixed to the floor allow for a more normalised dining experience. Astronauts strap themselves into chairs with thigh and foot supports and eat from magnetised trays using forks, knives and spoon.

Antimicrobial materials line the walls in the room, preventing the spread of bacteria. Historically, space food was mainly dehydrated or provided in pastes and eaten from tubes.

As science and technology have provided us with new forms of food processing, packaging and ingredients, the foods have also improved to now resemble many meals we have on Earth. When planning which foods to send into space, they are divided into the following groups:. Fresh foods - produce with a two-day shelf life such as fruit and vegetables are refrigerated onboard the spacecraft and consumed quickly to avoid spoilage. As vitamins and nutrients can generally be satisfied by other means, this produce is sent to keep morale high.

Irradiated foods - meat and dairy produce have ionising radiation applied to them before packaging. Intermediate moisture - these foods contain a small quantity of water low enough to limit microbial growth and are often soft in texture. Processes such as salting or sun-drying are used in the creation of these items and require no further preparation.

Natural form foods - foods such as nuts, biscuits and chocolate bars are simply packaged and ready to eat. Rehydratable foods and drinks - for a long time, this was the standard method of preparing food for space. These products have water returned to them when the astronauts are ready to eat.

Every two months, an automated spacecraft, such as the European Space Agency's 'Automated Transfer Vehicle' or the Russian's 'Progress' spacecraft, dock with the ISS loaded with fresh fruit, water and pre-packaged meals. To build comradeship between the different nationalities aboard the ISS, astronauts choose from a broad menu of foods from their country which are shared with their teammates.
