Dishing up 3D printed food, one tasty printout at a time

Singapore researchers develop new method for 'printing' fresh vegetables, leading to tastier, more nutritious food for patients with swallowing difficulties

Dishing up 3D printed food, one tasty printout at a time
2021-02-04
(Press-News.org) Researchers from Nanyang Technological University, Singapore (NTU Singapore), Singapore University of Technology and Design (SUTD) and Khoo Teck Puat Hospital (KTPH) have developed a new way to create "food inks" from fresh and frozen vegetables, that preserves their nutrition and flavour better than existing methods.

Food inks are usually made from pureed foods in liquid or semi-solid form, then 3D-printed by extrusion from a nozzle, and assembled layer by layer.

Pureed foods are usually served to patients suffering from swallowing difficulties known as dysphagia. To present the food in a more visually appetising way, healthcare professionals have used silicone moulds to shape pureed foods, which is labour and time intensive, and requires storage.

While 3D food printing means food can be easily produced in a desired shape and texture in a shorter time, the dehydrated food and freeze-dried powders used as food inks usually contain a high percentage of food additives such as hydrocolloids (HCs) to stabilise the ink and enable a smoother printing process. High concentration of HCs usually changes the taste, texture and aroma of the printed food, making it unappetising to patients with dysphagia. This may lead to reduced food consumption and malnutrition among patients.

To overcome this challenge, the research team explored various combinations of fresh and frozen vegetables to make the food inks stable.

Not only were they able to better preserve the nutrition of the printed food, they also made it more palatable. This new method of making food inks should lead to increased meal consumption by patients, contributing positively to their physical health and mental state of mind.

Additionally, the team discovered that vegetables could be broadly classified into three categories with each requiring a different hydrocolloid treatment in order to become printable. For instance, garden pea, carrot and bok choy were chosen as representatives in each category, requiring no HCs, one type of HC and two types of HCs, respectively (refer to images).

Prof Yi Zhang, the principal investigator from the NTU team said, "Our technology helps to provide dysphagic patients with adequate nutrient-rich and safe diets. Their feeding is more dignified, enabling them to socialise and consume meals that look, feel and taste like regular food. Our method of 3D printing fresh vegetables can be used easily in hospitals, nursing homes, day care centres for the ageing population with dysphagia and other swallowing disorders. Our research is also another step forward in digital gastronomy, where we can cater to specific requirements prescribed by dieticians, such as nutrition customisation and visual appeal."

Prof Chua Chee Kai, corresponding author and the Head of Pillar, Engineering Product Development at SUTD, added: "The next frontier of additive manufacturing is 3D food printing. As the 3D food printing landscape is increasingly evolving, we are excited to continue pushing the boundaries of this industry to find innovative solutions for global issues such as food security and sustainability."

Gladys Wong, co-principal investigator and Senior Principal Dietitian from KTPH said: "3D Food Printing is more than a novelty. I believe it will be a viable approach in the near future in providing sustenance and nourishment to our increasing ageing population. Our frail, elderly patients as well as those with swallowing difficulties will be able to enjoy a visually presentable and pleasurable dining experience even with a restrictive diet of smooth pureed dishes."

Politicians must be held to account for mishandling the pandemic

2021-02-04
Politicians around the world must be held to account for mishandling the covid-19 pandemic, argues a senior editor at The BMJ today. Executive editor, Dr Kamran Abbasi, argues that at the very least, covid-19 might be classified as 'social murder' that requires redress. Today 'social murder' may describe a lack of political attention to the conditions in which people are born, grow, live, work and age that exacerbate the pandemic. When politicians and experts say that they are willing to allow tens of thousands of premature deaths, for the sake of population immunity or in the hope of propping up the economy, is that not premeditated ...

New clues to how muscle wasting occurs in people with cancer

2021-02-03
UNIVERSITY PARK, Pa. -- Muscle wasting, or the loss of muscle tissue, is a common problem for people with cancer, but the precise mechanisms have long eluded doctors and scientists. Now, a new study led by Penn State researchers gives new clues to how muscle wasting happens on a cellular level. Using a mouse model of ovarian cancer, the researchers found that cancer progression led to fewer skeletal muscle ribosomes -- particles in the cell that make proteins. Because muscle mass is mainly determined by protein synthesis, having less ribosomes likely explains why muscles waste away in cancer. Gustavo Nader, associate professor of kinesiology and physiology at Penn State, said the findings suggest a mechanism for muscle wasting that could be relevant ...

Heightened immigration enforcement has troubling impact on US citizen children

Heightened immigration enforcement has troubling impact on US citizen children
2021-02-03
DURHAM, N.C. -- Harsher immigration law enforcement by U.S. Immigration and Customs Enforcement leads to decreased use of prenatal care for immigrant mothers and declines in birth weight, according to new Duke University research. In the study, published in PLOS ONE, researchers examine the effects of the federal 287(g) immigration program after it was introduced in North Carolina in 2006. Under 287(g) programs, which are still in effect, local law officers are deputized to act as Immigration and Customs Enforcement (ICE) agents, with authority to question individuals about immigration status, detain them, and if necessary, begin deportation proceedings. According to the study findings, the 2006 policy change reduced birth weight ...

Hypoxia, a feature inside solid cancer tumors, reprograms methylation of ribosomal RNAs

Hypoxia, a feature inside solid cancer tumors, reprograms methylation of ribosomal RNAs
2021-02-03
BIRMINGHAM, Ala. - Hypoxia -- where a tissue is deprived of an adequate supply of oxygen -- is a feature inside solid cancer tumors that renders them highly invasive and resistant to treatment. Study of how cells adapt to this critical stressor, by altering their metabolism to survive in a low-oxygen environment, is important to better understand tumor growth and spread. Researchers led by Rajeev Samant, Ph.D., professor of pathology at the University of Alabama at Birmingham, now report that chronic hypoxia, surprisingly, upregulates RNA polymerase I activity and alters the methylation patterns on ribosomal RNAs. These altered epigenetic marks on the ribosomal RNAs appear to create a pool of specialized ribosomes that can differentially ...

Kangaroo overgrazing could be jeopardising land conservation, study finds

Kangaroo overgrazing could be jeopardising land conservation, study finds
2021-02-03
As a native animal, kangaroos aren't typically considered a threat to Australian vegetation. While seen as a pest on farmland - for example, when competing with livestock for resources - they usually aren't widely seen as a pest in conservation areas. But a new collaborative study led by UNSW Sydney found that conservation reserves are showing signs of kangaroo overgrazing - that is, intensive grazing that negatively impacts the health and biodiversity of the land. Surprisingly, the kangaroos' grazing impacts appeared to be more damaging to the land than rabbits, an introduced species. "The kangaroos had severe impacts on soils and vegetation that were symptomatic of overgrazing," says Professor Michael Letnic, senior author of the paper and ...

Poll shows inequality in older adults' ability to isolate a COVID-positive person at home

Poll shows inequality in older adults ability to isolate a COVID-positive person at home
2021-02-03
One of the most important ways to stop the spread of COVID-19 is for people who have tested positive, or have symptoms, to isolate themselves from the other people they live with. But a new University of Michigan poll suggests that nearly one in five older adults don't have the ability to do this - and that those who are Hispanic or Black, or who have lower incomes or poor health to begin with, are more likely to lack a safe isolation place in their home. The poll also shows significant inequality in another key aspect of staying safe and healthy during the pandemic: the ability to get outside for fresh air and exercise, and to engage safely with friends, ...
