New biosensor accurately and efficiently determines meat freshness

The freshness of animal meat is an essential property determining its quality and safety. With advanced technology capable of preserving food for extended periods of time, meat can be shipped around the globe and consumed long after an animal dies. As global meat consumption rates increase, so too does the demand for effective measures for its age.

Unique manufacturing method produces more appealing vegan meat

Vegan food is often sidestepped due to its rubbery consistency. Food technology researchers at Lund University in Sweden have now developed a way to make vegan food more appetizing by using new combinations of raw materials. So far, the research field for plant-based meat imitations, known as meat analogs, has been very small—but is now set to "explode." The team at Lund is among those that have published the most research in the world on the topic.

Scientists spin naturalistic silk from artificial spider gland

Researchers have succeeded in creating a device that spins artificial spider silk that closely matches what spiders naturally produce. The artificial silk gland was able to re-create the complex molecular structure of silk by mimicking the various chemical and physical changes that naturally occur in a spider's silk gland.
