Injecting meatballs with collagen can help the meat to retain the important nutrients iodine and thiamine, a new study by researchers from the Agricultural University of Poznan in Poland shows.
During the processes of storing and cooking, pork meatballs tend to lose a percentage of iodine and thiamine. Adding collagen fibre or collagen hydrolysate saturated with potassium iodide to meat makes it more stable than potassium iodide introduced using iodized table salt. The collagen enhancement works on fresh meat before cooking, but the effect also lasts during cold- or freezer-storage (SCI’s Journal of the Science of Food and Agriculture, doi 10.1002/jsfa.2844).
In this study, collagen was injected into meatballs to act as a carrier of iodine salts. After storage and cooking of the meatballs, levels of iodine and thiamine were measured and they were shown to have maintained within the meat.
Thiamine (vitamin B1) helps the body’s cells to convert carbohydrates into energy. It is found in many foods, like lean meats, but especially pork. Insufficient amounts of thiamine can lead to nerve damage, weakness, fatigue and psychosis.
A lack of iodine in a diet can lead to iodine deficiency disorders (IDD), such as goiter or impeded mental development, which are a considerable problem in many countries. This study could help countries suffering from a great percentage of IDD to increase the iodine in their diets.
Professor Hans Burgi of the International Council for Control of Iodine Deficiency Disorders (ICCIDD) in Switzerland agrees iodide in food can be unstable. While he doesn’t think that it is necessary to inject all meats with collagen, he believes there can be some benefits. “Since in iodine deficient areas, iodine is supplemented by salt as a carrier, improving its stability with collagen is of interest,” he said.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
