Launched by the Society of Biomaterials together with international journals including Biomaterials and Materials Today, the award recognises and encourages early career researchers in biomaterials science with outstanding contributions to the field. An award ceremony will be held at the 12th World Biomaterials Congress on 26–31 May 2024 in Daegu, South Area. Dr Zhao will receive the award in person and share on her innovative research.

PolyU-led novel food waste-derived 3D printing materials to be showcased at InnoCarnival 2023

The novel food waste-derived 3D printing materials developed by the Research Institute for Future Food (RiFood) will be showcased at the InnoCarnival 2023 to be held from 28 October to 5 November 2023 at Hong Kong Science Park. Prof. WONG Ka Hing, Director of RiFood, said that food waste can be simply divided into two types. “The first type is kitchen waste, which mainly comes from households or restaurants. The second type is food/agro-waste generated by food processing plants. As these food/agro-wastes come from food factories, waste production is concentrated and the waste composition is relatively homogenous. Examples include spent coffee grounds, spent tea leaves, potato peels, etc. The innovative green technology we showcase is upcycling the spent coffee grounds and tea leaves into novel 3D printing materials,” he explained. 3D printing has become very popular in recent years, and Fused Deposition Modelling (FDM) is the one of the most commonly used 3D printing methods. FDM can print various tools with plastic as the main printing material. Prof. Wong said that their innovative green technology can combine spent coffee grounds/tea leaves with polylactic acid (PLA) to produce a novel 3D printing material. “This novel food waste-derived 3D printing material (up to 50% of food waste) can be used in FDM 3D printers without affecting its printing performance. With a strong tensile strength (10-40 MPa), the novel 3D printing material can be used for a wide range of applications, such as production of modular furniture and display goods,” he elaborated. This novel sustainable 3D printing material exhibits excellent ductility and can be used for printing shock-absorbing structures. To ensure compliance with the low-carbon policy, the novel 3D printing material is customisable, scalable, does not require any chemical additives during the mass production process, and its carbon footprint is about 36% lower than that of commercial PLA 3D printing material. The team is going to collaborate with a local coffee chain to produce eco-friendly 3D-printed furniture and display goods using their spent coffee grounds. Various 3D printed products made from spent coffee grounds will also be showcased at the Carnival.

RiFood develops functional selenium nanoparticles for managing postmenopausal osteoporosis

  October 20 2023 marks this year’s World Osteoporosis Day. On the same day, Prof. WONG Ka-hing, Director of the Research Institute for Future Food (RiFood) and Professor in the Department of Food Science and Nutrition (FSN), shared with the media his team’s latest research on the development of novel Cs4-selenium nanocomposites (Cs4-SeNPs) for managing postmenopausal osteoporosis.    Selenium is an essential trace mineral to human health, playing important roles in many physiological functions. In the past decades, substantial evidences have demonstrated that Se deficiency is detrimental to bone microarchitecture and associated with osteoporosis, suggesting its crucial role in bone metabolism. Recently, selenium nanoparticles (SeNPs) have become a new research target, since they were found to possess remarkable bioactivity and lower toxicity compared to those selenocompounds commomly found in foods. Nevertheless, scientific research concerning their effects on bone health is currently very limited.   By using the polysaccharide-protein complex isolated from Cordyceps sinensis, Prof. Wong has successfully prepared novel selenium nanoparticles (entitled “Cs4-SeNPs”), with well-characterized structure and high stability. Interestingly, Cs4-SeNPs (10μM) were found to markedly induce proliferation, differentiation, and mineralization of the pre-osteoblast murine MC3T3-E1 cells. More importantly, Cs4-SeNPs (25-500μg/kg BW/d) exhibited promising in vivo bone protective efficacy against OVX-induced osteoporosis by promoting bone formation, inhibiting bone resorption, and improving bone microarchitecture after oral gavage for 6 weeks. This patented nanotechnology has gained wide recognition with various international awards, while the research findings have been recently published in Journal of Functional Foods.   Further investigation on Cs4-SeNPs’ gastrointestinal stability, intestinal absorption and metabolism is now underway. The team look forward to collaborating with the industry in further development of related health food products and drugs.   Online coverage: CRHK - https://polyu.me/3RZVpj4 Oriental Daily News - https://polyu.me/3twkkjV am730 - https://polyu.me/46UdmUm Ta Kung Pao - https://polyu.me/46XUy6Q Wen Wei Po - https://polyu.me/48XfxIx Read the full research paper: https://doi.org/10.1016/j.jff.2023.105832   

理大研究：逾七成半剖腹產母親遇到哺乳困難 剖腹產嬰兒益菌量近乎零 不同配方奶粉建立腸道益菌效果差異超過40倍

香港，2023年6月27日 - 香港大約每五個初生嬰兒便有兩個經剖腹分娩。香港理工大學（理大）就剖腹產嬰兒建立早期腸道益菌情況進行研究，發現逾七成半（77%）採用剖腹分娩的母親曾遇到哺乳困難，包括較遲上奶及乳汁不足，當中近七成（69%）對此感到壓力，而需要選擇配方奶粉餵哺嬰兒。然而，調查發現就補足剖腹產嬰兒腸道益菌效果方面，不同配方奶粉差異高達 40 倍。 理大去年就不同分娩方式對腸道微生物發展進行本地首項專門研究，發現剖腹產嬰兒腸道內雙歧桿菌水平近乎零；雙歧桿菌是一種可協助嬰幼兒建立良好免疫力以及保持腸道健康的關鍵益菌，可透過餵哺補足。因此，理大今年進行第二階段研究，冀了解剖腹產嬰兒建立腸道益菌的有效方法。 母乳是最好且最適合為嬰兒提供包括益生菌等所需營養的來源。然而，研究發現採用剖腹分娩的母親往往遇到哺乳困難，需要選擇配方奶粉補足嬰兒的營養需要。配方奶粉即使未能完全取代母乳中的分泌型免疫球蛋白A、益生元和益生菌，以及賀爾蒙等營養，但仍可提供嬰兒成長的元素。 理大研究人員收集了75個分別接受15款配方奶粉餵哺的本地剖腹產初生嬰兒的糞便樣本，比較當中雙歧桿菌的數量。研究發現，不同樣本在一周後腸道內雙歧桿菌的數量可出現高達 40 倍差異。當中為剖腹產嬰兒專研的益生致親組合配方可最快補足益菌數量，在首周後已追至貼近接受母乳餵哺的順產嬰兒腸道益菌之水平，並一直持續至四周後。在十二周後，雖然不同樣本中的雙歧桿菌水平已大致相若，不過剖腹產益生致親組別的短雙歧桿菌的數量仍然處於明顯較高水平。 第2頁 理大食品科學與營養學系副系主任、未來食品研究院副院長邱家琪博士表示：「香港是亞洲區內剖腹分娩率最高的地方之一。因此，我們希望透過科研，了解剖腹產嬰兒的特別營養需要。我們的研究發現腸道益菌數量與餵哺方式息息相關，不同配方產品的效用會有明顯差異。雖然母乳是初生嬰兒最好的營養來源，但如因不同理由而需要餵哺配方奶粉，父母應了解不同餵哺方式所提供的營養成分，幫助剖腹產嬰兒及早建立良好的腸道微生物組成。」 兒科專科徐梓筠醫生指出，剖腹產嬰兒及早提升腸道益菌，可以增強剖腹產嬰兒的免疫力。徐醫生認為：「剖腹產嬰兒在出生過程中未有接觸母親產道，較少接觸媽媽的產道益菌，尤其是雙歧桿菌。雙歧桿菌是母乳、母乳餵養的嬰兒腸道和產道中最常見的有益細菌，有助嬰兒建立免疫力。剖腹產嬰兒的腸道微生態容易出現失衡，害菌比例較高，而益菌比例較少，嬰兒較多機會出現敏感及腸道問題，如腹瀉﹑便秘等，所以剖腹產嬰兒有特定的營養需要，需要及早補足益生菌。雖然母乳能提供最好及最適合嬰兒的營養和益生菌，但若然母乳不足，父母可以考慮選用為剖腹產嬰兒專研的配方。這類專研配方含有產道同類益菌種及益生元，能為嬰兒補充益菌來源，及早打好免疫基礎，科研實證可減少將來出現過敏、腹瀉及上呼吸道感染的機會 。研究亦指出，即使是一歲以上的剖腹產嬰兒，補充益生菌及益生元也有助他們建立長遠的免疫保護。如要需要，最好詢問醫生的意見。 」
