In a world where the demand for healthier diets is on the rise, a new review published in Engineering explores how innovative food processing technologies can enhance the utilization of nutrients in staple food crops. The study, titled "Innovative Food Processing Technologies Promoting Efficient Utilization of Nutrients in Staple Food Crops," delves into the challenges of traditional food processing methods and highlights the potential of modern techniques to improve nutritional profiles and reduce waste.
The review, led by researchers from Fuzhou University, South China University of Technology, National University of Singapore, ETH Zurich, University of Alberta, and the University of Arkansas, examines the common nutritional challenges faced during the processing of grains, legumes, and tubers. Traditional methods often result in nutrient losses, reduced utilization efficiency, and the formation of potentially harmful substances. To address these issues, the authors explore a range of innovative processing technologies, including microwave (MW), pulsed electric field (PEF), ultrasound, modern fermentation, and enzyme technology.
One of the key findings is that these innovative technologies can significantly enhance nutrient utilization efficiency. For example, microwave treatment has been shown to improve food quality by retaining more nutrients, such as vitamins and bioactive compounds, compared to conventional methods. It also reduces anti-nutritional factors like phytic acid and trypsin inhibitors in grains, thereby enhancing food safety and quality. Similarly, pulsed electric field technology can modify starches, making them more digestible and improving the overall nutritional value of food products.
The study also highlights the potential of modern fermentation and enzyme technologies. Fermentation, a process that uses microorganisms to convert carbohydrates into acids, gases, or alcohol, can enhance the nutritional value and digestibility of food. Advances in synthetic biology and gene editing have further optimized fermentation processes, making them more efficient and specific. Enzyme technology can break down complex molecules, improve dough properties, and reduce allergenicity in foods.
The review emphasizes the importance of integrating these technologies to achieve optimal results. For instance, combining microwave and ultrasound technologies can improve the efficiency of frying processes, reducing oil absorption and energy consumption. Similarly, integrating fermentation with enzyme treatment can enhance the extraction of bioactive compounds and improve the nutritional profile of food products.
The authors also discuss the challenges associated with these innovative technologies, such as high energy consumption and equipment costs. However, they argue that advancements in artificial intelligence, big data, and the Internet of Things could help overcome these limitations by optimizing processing operations and improving resource utilization.
The review underscores the potential of innovative food processing technologies to address the global food crisis by improving the nutritional quality and sustainability of staple food crops. As the food industry continues to evolve, the integration of these advanced technologies could play a crucial role in meeting the growing demand for healthier diets and reducing food waste.

Hilde Storrøsæter is worried about the teaching of geography in schools.
Geography as a school subject is under pressure. There aren't enough qualified teachers and it loses out to other subjects in school. In many countries, important aspects are left out of the geography curricula.
"Alarm bells should be ringing, both in the field and among teachers in schools. The development we are seeing in geography as a subject is critical. This failure affects the students' ability to understand how things are connected in a troubled and confusing world," she said.
Storrøsæter is a geographer and assistant professor at the Norwegian University ...
The brains of politically extreme individuals, whether left- or right-leaning, appear to respond to and process political information in surprisingly similar ways, according to research published by the American Psychological Association.
“Both extreme liberals and extreme conservatives consumed the same political content, and even though they held vastly different beliefs, their brains appeared to process the information in a very similar manner,” said Oriel FeldmanHall, PhD, a professor of cognitive and psychological sciences at Brown University and co-author of the study, published in the Journal of Personality and Social Psychology. “In contrast, ...

Researchers at McGill University and the Douglas Institute have identified two specific types of brain cells that are altered in people with depression.
The study, published in Nature Genetics, opens the door to developing new treatments that target these cells and deepens our understanding of depression, a leading cause of disability worldwide that affects more than 264 million people.
“This is the first time we’ve been able to identify what specific brain cell types are affected in depression by mapping gene activity together ...
FRANKFURT. When a tree dies, it forms the foundation for new life: In a slow, invisible process, leaves, wood and roots are gradually decomposed – not by wind or weather but by millions and millions of tiny organisms. Fungi thread their way through the dead wood and degrade cell walls. Tiny animals such as insect larvae and mites gnaw through the tissue. And something very important happens in the process: The carbon stored in the plant is released, ultimately placing it at the disposal of plants again for the purpose of photosynthesis. But what exactly is responsible for performing this task in the global ...
Miami (August 28, 2025) – Using a care pathway focused on chronic obstructive pulmonary disease (COPD) can lead to shorter hospital stays, increased referrals to pulmonary rehabilitation, and improved standardization of care, according to a new study. The study is published in the July 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open-access journal.
COPD is an inflammatory lung disease, comprising several conditions, including chronic ...
For women with inflammatory bowel disease (IBD), pregnancy can be an uncertain time due to limited clinical data about how IBD medications impact pregnancy outcomes and infants who have been exposed to IBD medications in utero.
As a matter of policy, pregnant women are excluded from clinical trials of experimental therapies for IBD and when a new therapy achieves regulatory approval, there is only animal safety data, but no human pregnancy safety data.
For patients with IBD, stopping medication ...
One of our most popular summer soft fruits could last longer in the fridge thanks to pioneering new research conducted at Cranfield University. Researchers have recently published a new method to edit the DNA of raspberries, with the goal of creating more sustainable raspberry production and less food waste.
A first for gene editing in raspberry
The new study details a novel method for the isolation of single cells (protoplasts) from the leaf tissue of raspberry microplants grown in sterile tissue culture.
The protoplasts were then gene edited with CRISPR-Cas9, a revolutionary biotechnology ...
Wearable sensors can help prevent critical health issues by continuously monitoring physiological factors in real time. Specifically, sweat monitoring can provide valuable insights into electrolyte balance and overall health. Sodium concentration in sweat is a key indicator of hydration and muscle performance. Thin film materials, such as carbon nanotubes (CNTs) and ion-selective membranes (ISMs), have become central to the development of wearable sweat sensors. CNTs offer high mechanical flexibility and electrical conductivity, and ISMs enable non-invasive detection of specific ions in sweat.
Unfortunately, ...
Nanoparticles have diverse applications in modern science and industry, powering technologies like quantum-dot displays, nanocatalysts and drug delivery. Their unique physicochemical properties, which can be tuned by changing their size and shape, make them highly attractive. However, despite extensive research, the exact mechanisms and dynamics of monodisperse, or uniformly sized, nanoparticle formation and growth remain poorly understood.
The classical nucleation theory (CNT), based on the Gibbs-Thomson equation, has been the primary framework for understanding nanoparticle ...
