It is often a challenge to identify Salmonella species in samples heavily contaminated with competing microbiological flora. The new Xylose Lysine Tergitol-4 (XLT4) agar is a highly selective and very cost-effective medium for the specific detection and enhanced recovery of non-typhi Salmonella spp. from food (and other) samples. It enables labs to rapidly determine whether or not these pathogenic organisms are present, for effective monitoring even when faced with difficult materials. This agar is part of the company’s comprehensive and proven range of media for the isolation and culture of salmonellae from a variety of sample materials.

Novel application possibilities are now available for the bone health and nutrition market, including gummies, tablets and drinks. With bone mineral density declining from the age of 40, bone health and nutrition are of growing importance to both men and women. Dietary changes like the consumption of collagen peptides can delay the onset of agerelated conditions such as osteopenia, a precursor to osteoporosis. Rousselot’s range of natural Peptan collagen peptides have been proven, in many scientific studies, to support bone health. Clinical trials have shown that Peptan significantly improves bone mineral density and reduces bone loss. Peptan has also been recognized in supporting joint and muscle health as well as having skin health benefits. Easily digestible, Peptan can be used in varied applications, including inventive BonePlus gummies containing 20% Peptan enriched with calcium, chewy tablets and a mobility drink.

Pure™
Beta-Elemene is a natural ingredient which is used in the food, beverage and flavour & fragrance industries and is now available on a commercial scale. Compared to conventional Beta-Elemene, which is produced from herbs, it offers the advantages of a purity that exceeds 95%, a quality that is consistent and a 10-fold reduction in cost. The bio-based, natural Beta-Elemene Pure™ is produced using a proprietary fermentation process. Isobionics has succeeded in isolating the building block Beta-Elemene Pure™ with a purity exceeding 95%. Normally the purity of conventional Beta-Elemene is around 80%. The sustainable production process ensures consistent quality and provides the possibility to deliver large quantities. It is a process based on renewable resources that enables the company to realize a considerable cost reduction which is reflected in the sales price. Beta-Elemene is a constituent that occurs in citrus fruit as well as in 50 plants and herbs. It is mainly extracted from Curcuma Wenyujin (Ginger root). The traditional process for the isolation of Beta-Elemene is very labour intensive and additionally requires a lot of processing. Further, the original product is harvest-dependent and therefore quality is not consistent.

Ingredients
An advanced brain-support ingredient, phosphatidylserine with conjugated DHA for better brain function is available. The new Lipogen DPS can be served in softgels, capsules and tablets. Phosphatidylserine (PS), a phospholipid, and DHA, an omega-3 fatty acid, are major components of the brain’s cell membranes. The healthy structure of the cell’s membrane facilitates the signals of neuron communication, supporting brain functions. Lipogen PS received affirmed GRAS status (FDA “no questions”) in 2006 and is a clinically-proven nutritional supplement designed to help adults whose cognitive function is slowing down by improving age-related decline in memory and other cognitive capabilities, as described in two qualified, FDA-approved health claims. All Lipogen products are vegetarian, solvent-free and kosher-certified.
