Cake that can ward off cancer? Noodles that lower the cholesterol level? What sounds like an advertising stunt could soon be a reality.
Research scientists at the Fraunhofer Institute for Process Engineering and Packaging IVV in Freising have isolated valuable components of linseed and lupin seeds and experimentally incorporated them in various foodstuffs: the linseed in cakes, bread, dressings and sauces, the lupins in bread, rolls and pasta. The result is not only delicious, but healthy as well.
“Flax is not only high in soluble fiber, but also contains lignans. These substances are phytoestrogens, so they have a similar effect to that of the isoflavones that we know from soy beans. According to the literature, they protect the organism against hormone-dependent forms of cancer – that is, breast and prostate cancer,” says IVV project manager Dr. Katrin Hasenkopf. “The lupins, on the other hand, contain substances that our studies have found to have a positive impact on the cholesterol level.”
But how do the researchers isolate the valuable components? “We make use of the differing solubility of the various constituents: If the pH value is acidic, the unwanted bitter substances are the first to dissolve. If the pH value is then set back to neutral, you get the valuable proteins – without the bitter taste. We are also able to separate large components from small ones by a series of filtration steps,” explains Hasenkopf.
The scientists are already skilled at isolating the valuable constituents. Now they are preparing to conduct further investigations with the aim of confirming the effects they hope to see. “The healthy effects of linseed and lupin seeds are already known from literature, but so far there is a lack of conclusive scientific investigations on the subject. These substances undoubtedly have very high potential,” says Hasenkopf.
The researchers will be presenting the linseed and lupin foods at the Biotechnica trade fair in Hannover on October 7 through 9 (Hall 9, Stand E29). In about three years’ time, the expert hopes, the new cholesterol-lowering foodstuffs will be available on supermarket shelves – maybe even including cakes, bread rolls and sauces enriched with the valuable substances obtained from flax seeds.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
