Fish and Marine Oils
Fish- and marine-based oils are accepted by consumers as healthy oils because of their omega-3 fatty acid profiles. In a meta-analysis, Miller et al. (2014) showed that available evidence from 70 randomized controlled trials indicated that provision of EPA+DHA reduced systolic blood pressure. The strongest effects of EPA+DHA were observed among untreated hypertensive subjects, although blood pressure also was lowered among normotensive subjects.

At this year’s SupplySide West show, several suppliers showcased the versatility of fish- and marine-based oils. For example, DSM showcased its omega-3 offerings in beverages, including mango peach, lemon zest, piña colada, and key lime. The beverages provided between 720–1,500 mg of EPA and DHA. DSM offers life’sDHA, a vegetarian source of DHA omega-3 from algae. MEG-3 fish oil is a source of EPA and DHA omega-3 without the fishy taste or smell. life’sOMEGA is also an algal source of EPA and DHA omega-3. Maki et al. (2014) demonstrated that life’sOMEGA lowered triacylglycerol levels to a degree that was not different from that of a standard fish oil product, and that was significantly more than for a corn oil/soy oil control.

Stepan Lipid Nutrition offered a pink grapefruit omega-3-fortified water. The company offers Marinol, which is available in the form of a highly concentrated oil and a high-stability powder that offer different EPA and DHA ratios to provide specific health benefits.

Algarithm served algal DHA Omega Breakfast with Bacon Smoothies as well as burgers and s’more-flavored smoothies. There were also samples of the company’s DHA algal oil. Algarithm offers a 40% algae DHA oil, alphamega, which is vegetarian and non-GM.

Rimfrost discussed recent research on krill oil, a source of omega-3 fatty acids and protein. RIMFROST Antarctic krill oil provides omega-3s bound to phospholipids. Parolini et al. (2017) looked to evaluate the effect of Antarctic krill components on plasma lipids and atherosclerosis development in 60 apoEKO mice (a model of dyslipidemia and atherosclerosis). The krill oil diet was shown to reduce cholesterol levels, inhibit plaque development, and prevent liver damage. Krill proteins also reduced atherosclerosis development through mechanisms not involving lipid metabolism.

In June of this year, PLT Health Solutions introduced élantria Algal DHA, an ultra-stable algal DHA produced from non-GM microalgae Schizochytrium sp. élantria Algal DHA delivers 40% DHA by weight in an ultra-stable, nonconcentrated form. From a product developer’s standpoint, one of the features of élantria Algal DHA that stands out is its stability and shelf life.

In April, ADM introduced Onavita DHA Algal Oil. The new DHA oil is produced from a high-quality, reliable U.S. algae supply. Onavita DHA Algal Oil can be used in a wide variety of dietary supplements and fortified food products and provides vegan and allergen-free labeling options for food, beverage, and supplement developers.

Flaxseed Oil
Flaxseed’s nutritional profile includes being high in fiber, omega-3 fatty acids, and lignans. More than 70% of fat in flax is of the healthful polyunsaturated type. What makes flax oil unique is its high ratio of alpha-linolenic acid (an omega-3 fatty acid) to linoleic (omega-6 fatty acids). Last year, ADM also launched Onavita Flaxseed Oil. The oil features non-GM plant-sourced omega-3s. The FDA considers products containing at least 160 mg of alpha linolenic acid/serving, like what is found in Onavita flaxseed oil, to be a good source of omega-3s.

Chia Oil
The chia seed is popular in the health arena because it is high in omega-3 fatty acids, fiber, and calcium. At SupplySide West, Benexia showcased a plant-based ultra-high temperature pasteurized chia milk. The company also offers cold-pressed and filtered chia oil. It has a high concentration of alpha-linolenic acid. The most important antioxidants found in Benexia Chia Oil are chlorogenic acid and caffeic acid. Both components contribute in a significant proportion to the strong antioxidant activity of Benexia Chia Oil. Chia oil naturally contains tocopherols and phytosterols, which in addition to contributing to high oxidative activity, have beneficial effects for the prevention of cardiovascular conditions.

Cranberry Seed Oil
Fruit d’Or cranberry seed oil is approved by Health Canada for maintenance of good health. Fruit d’Or Nutraceuticals has received Natural Product Number (NPN #80079040) from Health Canada’s Natural and Non-prescription Health Products Directorate, for both Cran Naturelle and Cran d’Or cranberry seed oil. Fruit d’Or cranberry seed oil is registered with an NPN claim as a “source of omega-3 and omega-6 fatty acids for the maintenance of good health.” Each tablespoon (15 ml) contains 34.8% of alpha-linolenic, 36.6% of linoleic, and 19.9% oleic acid.

Next month’s Nutraceuticals column will give an update on nutritional innovations in beverages.
