Macro- and microelements in some species of marine life from the Sea of Okhotsk

Abstract

Introduction. Residents of northern regions have a diet low in essential macro- and microelements. The Sea of Okhotsk is an enormous source of fish and non-fish products. We aimed to determine mineral contents in marine fish, shellfish, and algae in order to assess if they could satisfy the daily requirement for these elements through fish and non-fish consumption.
 Study objects and methods. Our study objects were saffron cod (Eleginus gracilis L.), blue-headed halibut (Reinhardtius hippoglossoides L.), commander squid (Berryteuthis magister L.), northern shrimp (Pandalus borealis L.), salted pink salmon caviar (Oncorhynchus gorbuscham L.), and kelp (Laminaria L.). The contents of 25 macro- and microelements were determined by atomic emission spectrometry and mass spectrometry with inductively coupled argon plasma.
 Results and discussion. The absolute contents of macro- and microelements in the marine species were used to assess the proportion of the recommended daily requirement that they account for. Also, we performed a thorough comparative analysis of mineral quantities in the studied species of marine fish, pink salmon caviar, shellfish, and algae from the Sea of Okhotsk. Finally, we examined the elemental status of the coastal residents belonging to the “northern type” and identified their deficiencies of vital chemical elements. 
 Conclusion. Some chemical elements in the studied marine species from the Sea of Okhotsk (Magadan Region) satisfy over 100% of the daily human requirement for these minerals. Therefore, their products can be recommended as part of a northern diet in order to compensate for the deficiencies of certain minerals.

Algae: Study of Edible and Biologically Active Fractions, Their Properties and Applications

“…The active components of algae can remove harmful elements from the human body and also have ulcer- and wound-healing properties. Microalgae extracts can increase hemoglobin concentration, reduce the level of sugar in the blood, and exhibit analgesic, bronchodilatory, and hypotensive activities [ 17 ]. As a result, more and more attention is being paid to applying algae in the pharmaceutical, cosmetic, and food industries [ 16 ].…”

Review of Studies on Joint Recovery of Macroalgae and Marine Debris by Hydrothermal Liquefaction

“…At the same time, the biomass of macroalgae has significant resource potential [3,4]. There are some articles on macroalgae processing with the production of bioethanol [5], biogas [6,7], biofuels [2,8,9] nutrients [10], and biologically active substances [11].…”

Isolation of Valuable Biological Substances from Microalgae Culture

“…Active research has identified a wide range of bioactive compounds in microalgae. It demonstrated that microalgae can be used to produce protein, polyunsaturated fatty acids, vitamins, minerals, and carbohydrates [ 5 , 6 ]. Through antioxidant properties, anti-inflammatory, antimicrobial, and antiviral effects, these compounds may play an important role in cattle, poultry, shellfish, and fish feed, as well as human functional foods, contributing to the prevention of stomach ulcers, constipation, anemia, diabetes, and hypertension [ 7 , 8 ].…”
