Are all proteins alike? Nestlé researchers seek answers

March 2011. Not all proteins are alike. Some are digested and absorbed rapidly, while others may impact metabolism and glucose control. Scientists at the Nestlé Research Center, Lausanne, Switzerland, compared the effects of various protein sources on energy metabolism, satiety and glucose control in humans. Protein is a beneficial nutrient for weight control not only because it takes more energy to digest and absorb proteins, but also because protein may influence appetite and satiety (the feeling of fullness after a meal). Since little is known about the magnitude of these effects among different protein sources (milk, vegetable or animal proteins), Nestlé researchers conducted a clinical trial to find answers.
Three meals of equal calorie content consisting of 50% protein from whey, casein and soy protein respectively (with 40% carbohydrate and 10% fat), and a fourth, high-carbohydrate (95% carbohydrate) meal were given to healthy adults. Researchers measured the energy expenditure, thermic effect, glycemic response and appetite sensations before and after the four different meals. Results showed that the protein-rich meals led to a greater energy expenditure and thermic effect than the high-carbohydrate meal, that the effects of whey were significantly greater than those of casein and soy and were accompanied by a trend for greater fat oxidation. All three proteins (in the presence of glucose) significantly lowered peak glycemia after the meal. Furthermore, casein and soy protein lowered glycemia with little, if any, increase in insulin secretion above that of the glucose component of the meal. “Our study confirmed that protein-rich meals promote greater energy expenditure than carbohydrate-rich meals of equal calorie content.” says Dr. Kevin Acheson, Nestlé scientist leading the study. “These findings strengthen the evidence that increased protein content in the diet promotes weight control. Different protein sources could be used for personalized nutrition needs.”
Nestlé researchers will extend the investigation of these results to the acute and long-term health benefits of proprietary protein sources.

life'sDHA™ Adds Tremendous Marketing Value - DHA for Dietary Supplements

Docosahexaenoic acid, DHA, is a long-chain omega-3 fatty acid that provides health benefits for people of all ages. DHA omega-3 is found throughout the body. Specifically, it is a major structural fat in the brain and retina accounting for up to 97% of the omega-3 fats in the brain and up to 93% of the omega-3 fats in the retina. DHA is also a key component of the heart. While it has been shown that DHA is important for health and development, it’s difficult for most people to get enough through diet alone. This is because the primary dietary sources of DHA are limited to organ meat and fatty fish. And, although expert bodies such as the American Heart Association and the USDA (through its Dietary Guidelines for Americans) recommend eating fish regularly, other agencies including the Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) caution against eating certain types of fish because of contaminant concerns.
Fortunately, as the interest in improving health through nutrition continues to grow, and research continues to demonstrate just how important DHA is to our health, the demand for DHA supplements and foods fortified with DHA will continue to increase. Now is the time to capitalize on this DHA marketing opportunity. Whether you are looking to enhance a custom blend or differentiate yourself in the DHA omega-3 market, life'sDHA™ from algae is the smart choice.
Customers respond to high quality ingredients, such as life'sDHA™.
·    life'sDHA™, produced from algae, is a vegetarian source of DHA compatible with many foods or beverages. Algae is the only vegetarian source that provides a meaningful amount of DHA. Other vegetarian sources of omega-3s, such as flax seeds, walnuts and certain vegetable oils, contain ALA (alpha-linolenic acid), not DHA. As a vegetarian source of DHA, life'sDHA™ is suitable for use in traditionally vegetarian foods and beverages, such as breads, cereals, yogurts, cheeses, milks and juices. In addition, life'sDHA™ is both Kosher and Halal.
·    DHA is the only omega-3 shown to provide brain, eye and heart health benefits. EPA, found in fish oil, has been shown to support cardiovascular health but has not been proven to play a role in brain or eye health. ALA, found in flaxseed oil, has no known independent benefits on brain or eye health and there are insufficient data to support its role in cardiovascular health.
·    life'sDHA™ is produced in a controlled environment, eliminating the risk of oceanic contamination. From start to finish, life'sDHA™ is produced in an FDA-inspected facility, under current Good Manufacturing Practice (cGMP) regulations with controls in place to ensure the highest quality product. Because the algae is grown outside of the ocean, there is no risk of ocean-borne contaminants such as PCBs and dioxins.
·    In March of 2004, the U.S. Food and Drug Administration (FDA) completed a favorable review of the Company's generally recognized as safe (GRAS) notification regarding the use of its DHA oil as an ingredient in foods and beverages.
·    life'sDHA™ also has Novel Foods approval for use in supplements and a variety of foods in Europe as well as Australia/New Zealand.
·    life'sDHA™ is a high quality product with excellent sensory characteristics and shelf life. Made from a patented vegetarian source and production process, life'sDHA™ will not adversely affect your product’s sensory characteristics. In addition, life'sDHA™ is highly concentrated so less is needed. Foods and beverages fortified with life'sDHA™, including cereal bars, yogurts, bread, cheese and soymilk, have demonstrated excellent shelf life and taste performance.

Extraction of Nutraceutical Components from Algae Using Supercritical CO2

Nadine Igl-Schmid, Josef Schulmeyr, Andreas Wuzik

Supercritical CO2 extraction pressuresDuring food processing organic or inorganic liquids are conventionally used for separation purposes. While supercritical CO2 extraction is increasingly applied as an alternative at industrial scale, details of processing  are critically important to preserve functional properties of the ingredients, for example carotenoids in nutritional products or dietary supplements. The authors describe algae species which they find best suited for carotenoid extraction and their experience with extraction from sensitive biomass at different pressures with varying outcomes of  supercritical CO2 extraction.
