IsoLife publication:’No de novo sulforaphane biosynthesis in broccoli seedlings’.

December 17, 2010

The isothiocyanate sulforaphane, present in significant amounts in broccoli (Brassica oleracea L.) seedlings in the form of its precursor glucoraphanin, has been identified as an inducer of quinine reductase, a phase-II detoxification enzyme known for its anticarcinogenic properties. Here, we unambiguously demonstrate in that sulforaphane is not biosynthesised de novo during the first week of seedling development. Both 12C (99 atom%12C) and 13C (98 atom% 13C) broccoli seeds were produced and subsequently germinated and grown either in a 13CO2 or a 12CO2environment. Afterwards, the labelling degree of sulforaphane in seeds and in seedlings was analysed by HPLC–MS. We conclude that sulforaphane exclusively originates from seed reserves and that de novo biosynthesis is not detectable in broccoli seedlings. Our findings have been published in Food Chemistry (for further details see Applications). Ask a reprint.

Healthy food: Potato products with low caloric values and high dietary fiber contents.

March 1, 2009

Potatoes are a good, natural source of carbohydrates, energy, dietary fiber, minerals, and vitamins.13C-labeled potatoes are extremely helpful to investigate the caloric properties and the behavior of functional components of specific potato varieties in a normal daily diet. For this purpose, IsoLife has produced several stable isotope labelled potato varieties during recent years. One of the projects – co-financed by ‘Samenwerkingsverband Noord-Nederland’ and performed by IsoLife in co-operation with the partners HZPC, Aviko and the University Medical Center Groningen – investigated whether the caloric value of potatoes and potato products could be (further) decreased by specific procedures in potato breeding or product processing.

HZPC Holland BV is a breeding company and a trade company for the development and sales of innovative potato varieties in the potato supply chain with focus on potatoes for consumption and potatoes for French fries, chips and the food chain.
AVIKO BV is the largest Dutch producer of potato products with focus on health aspects.
The ‘Center for Medical Biomics’ (UMCG), the department of professor Roel Vonk, has contributed in areas like digestion, fermentation, and metabolism of potato components in relation to human health. The UMCG has co-ordinated the large EU-research project EUROSTARCH

The results, based on detailed experiments with 13C-labelled potato products, show that the caloric value of potato products can indeed be (further) decreased through changes in their composition.

Methane emission from plants: Yes they do! No they don’t!

April 27, 2007

In 2006, Nature published a sensational article by Keppler et al, who claimed that plants would be able to emit methane under aerobic conditions. A Dutch consortium consisting of IsoLife, Plant Research International, Plant Dynamics, Nijmegen Radboud University, Utrecht University tried to reproduce their results using a novel technique with uniformly 13C-labelled plants. We found methane emissions that were between 0.1% and 0.3% of the rates reported by Nature. Apparently, the textbooks do not have to be rewritten. Our findings have been published in New Phytologist (for further details see Applications; for more news read the News commentaries).Ask a reprint.
