Researchers from Nanyang Technological College, Singapore (NTU Singapore), Singapore College of Expertise and Design (SUTD) and Khoo Teck Puat Hospital (KTPH) have developed a brand new strategy to create “meals inks” from recent and frozen greens, that preserves their vitamin and flavour higher than present strategies.
Meals inks are often constituted of pureed meals in liquid or semi-solid kind, then 3D-printed by extrusion from a nozzle, and assembled layer by layer.
Pureed meals are often served to sufferers affected by swallowing difficulties often called dysphagia. To current the meals in a extra visually appetising means, healthcare professionals have used silicone moulds to form pureed meals, which is labour and time intensive, and requires storage.
Whereas 3D meals printing means meals could be simply produced in a desired form and texture in a shorter time, the dehydrated meals and freeze-dried powders used as meals inks often comprise a excessive share of meals components akin to hydrocolloids (HCs) to stabilise the ink and allow a smoother printing course of. Excessive focus of HCs often modifications the style, texture and aroma of the printed meals, making it unappetising to sufferers with dysphagia. This will likely result in diminished meals consumption and malnutrition amongst sufferers.
To beat this problem, the analysis workforce explored varied combos of recent and frozen greens to make the meals inks steady.
Not solely had been they in a position to higher protect the vitamin of the printed meals, additionally they made it extra palatable. This new technique of creating meals inks ought to result in elevated meal consumption by sufferers, contributing positively to their bodily well being and psychological mind-set.
Moreover, the workforce found that greens might be broadly labeled into three classes with every requiring a unique hydrocolloid therapy to be able to grow to be printable. For example, backyard pea, carrot and bok choy had been chosen as representatives in every class, requiring no HCs, one kind of HC and two sorts of HCs, respectively (refer to photographs).
Prof Yi Zhang, the principal investigator from the NTU workforce mentioned, “Our expertise helps to supply dysphagic sufferers with enough nutrient-rich and protected diets. Their feeding is extra dignified, enabling them to socialize and eat meals that look, really feel and style like common meals. Our technique of 3D printing recent greens can be utilized simply in hospitals, nursing properties, day care centres for the ageing inhabitants with dysphagia and different swallowing problems. Our analysis can also be one other step ahead in digital gastronomy, the place we will cater to particular necessities prescribed by dieticians, akin to vitamin customisation and visible enchantment.”
Prof Chua Chee Kai, corresponding writer and the Head of Pillar, Engineering Product Growth at SUTD, added: “The subsequent frontier of additive manufacturing is 3D meals printing. Because the 3D meals printing panorama is more and more evolving, we’re excited to proceed pushing the boundaries of this business to seek out progressive options for world points akin to meals safety and sustainability.”
Gladys Wong, co-principal investigator and Senior Principal Dietitian from KTPH mentioned: “3D Meals Printing is greater than a novelty. I consider it is going to be a viable method within the close to future in offering sustenance and nourishment to our rising ageing inhabitants. Our frail, aged sufferers in addition to these with swallowing difficulties will be capable of get pleasure from a visually presentable and pleasurable eating expertise even with a restrictive food plan of easy pureed dishes.”
