Barriers to adoption of biogenic carbonates in the food, pharmaceutical & supplement sectors

There is an increasing demand for environmentally sustainable sourcing of ingredients for the food, pharmaceutical and supplements industries. In the case of calcium carbonate (E170) as by-products from the egg and shellfish processing industries these have the potential to be sustainably sourced. In addition to their green credentials, biogenic carbonates have intrinsic benefits in terms of their chemical composition, such as a low heavy metal burden. However, their biogenic origin can potentially lead to manufacturing issues such as higher levels of co-mineralising components and the organic templates of their natural production. This contribution identifies the regulatory barriers to the adoption of biogenic eggshell calcium carbonate by assessing materials from biological sources along with commercial precipitated and ground carbonates against current regulatory standards

Evaluation of surface contamination with cyclophosphamide following simulated hazardous drug preparation activities using two closed-system products

Purpose. A preliminary investigation was conducted to evaluate and compare the effectiveness of two closed-system products in preventing contamination of typical pharmacy workplace surfaces with cyclophosphamide during simulated hazardous drug preparation activities in a controlled laboratory setting

Valsartan (Profiles of Drugs Substances, Excipients and Related Methodology)

Valsartan is an antihypertensive drug which selectively inhibits angiotensin receptor type II. This tetrazole derivative was first developed by Novartis and marketed under brand name Diovan® . This compound is orally active and is rapidly absorbed after oral doses, having a bioavailability of approximately 23% . Valsartan appears as a white or almost white hygroscopic powder. This compound must be kept in an air-tight container and should be protected from light and heat. It is available in film-coated tablets containing valsartan 40, 80, 160, or 320 mg, and capsules with dosage of 80 or 160 mg. Tablet combinations of valsartan with hydrochlorothiazide or amlodipine are also availabl

INFOGEST static in vitro simulation of gastrointestinal food digestion

peer-reviewedSupplementary information is available at http://dx.doi.org/10.1038/s41596-018-0119-1 or https://www.nature.com/articles/s41596-018-0119-1#Sec45.Developing a mechanistic understanding of the impact of food structure and composition on human health has increasingly involved simulating digestion in the upper gastrointestinal tract. These simulations have used a wide range of different conditions that often have very little physiological relevance, and this impedes the meaningful comparison of results. The standardized protocol presented here is based on an international consensus developed by the COST INFOGEST network. The method is designed to be used with standard laboratory equipment and requires limited experience to encourage a wide range of researchers to adopt it. It is a static digestion method that uses constant ratios of meal to digestive fluids and a constant pH for each step of digestion. This makes the method simple to use but not suitable for simulating digestion kinetics. Using this method, food samples are subjected to sequential oral, gastric and intestinal digestion while parameters such as electrolytes, enzymes, bile, dilution, pH and time of digestion are based on available physiological data. This amended and improved digestion method (INFOGEST 2.0) avoids challenges associated with the original method, such as the inclusion of the oral phase and the use of gastric lipase. The method can be used to assess the endpoints resulting from digestion of foods by analyzing the digestion products (e.g., peptides/amino acids, fatty acids, simple sugars) and evaluating the release of micronutrients from the food matrix. The whole protocol can be completed in ~7 d, including ~5 d required for the determination of enzyme activities.COST action FA1005 INFOGEST (http://www.cost-infogest.eu/ ) is acknowledged for providing funding for travel, meetings and conferences (2011-2015).
