The southern coast of Peru presents a wide diversity of seaweed, which could be used as a new sustainable source of nutritional and bioactive compounds. For the first time, we chemically characterized two species of brown (Macrocystis pyrifera) and red (Chondracanthus chamissoi) Peruvian seaweed. Both species contained significant amounts of proteins (5–12%), lipids (0.16–0.74%), carbohydrates (43.29–62.65%) and minerals (1300–1800 mg kg−1 dw: dry weight). However, the profiles of amino acids, fatty acids and minerals were highly dependent on species type. C. chamissoi had a higher content of essential amino acids and minerals than M. pyrifera (170% and 45%, respectively), while the presence of polyunsaturated fatty acids (ω 6) as well as the content of tocopherols was higher in M. pyrifera (15.77 g 100 g−1 and 2.37 μg 100 g−1, respectively). Additionally, both species presented significant concentrations of total polyphenols (39–59 mg GAE g−1) and a high antioxidant capacity (67–98 µM TE g−1). Although M. pyrifera and C. chamissoi seem to be excellent raw materials for the food and nutraceutical industry, both species contained toxic heavy metals (cadmium: Cd and nickel: Ni) which could affect the safety of their direct use. Therefore, new separation strategies that allow the selective recovery of nutrients and bioactive compounds from Peruvian seaweed are required.

Routine Identification

A total of 327 yeast strains from seawater, sediments, mud of salterns, guts of the marine fish and marine algae were obtained. After crude protein of the yeasts was estimated by the method of Kjehldahl, we found that eight strains of the marine yeasts grown in the medium with 20 g l−1 glucose contained more than 30.4 g protein per 100 g of cell dry weight. The results of routine identification and molecular methods show that they belong to Metschnikowa reukaui, Cryptococcus aureus, Aureobasidium pullulan, Yarrowia lipolytica and Hanseniaspora uvarum, respectively. With the exception of Aureobasidium pullulans 4#2 with nucleic acid of 7.7% (w/w), all other yeast strains contained less than 5.0% (w/w) of nucleic acid. Analysis of fatty acids shows that all the yeast strains tested had a large amount of C18:0 and C18:1 fatty acids while analysis of amino acids indicates that the yeast strains tested had a large amount of essential amino acids, especially lysine and leucine which are very important nutritive components for marine animals.

Pleurogrammus Monopterygius

Исследованы технохимические свойства скумбрии японской (Scomber japonicas) и терпуга северного одноперого (Pleurogrammus monopterygius). Установлено, что скумбрия и терпуг являются ценным пищевым сырьем, богатым биологически ценным белком, в котором содержатся все незаменимые аминокислоты. Аминокислотные составы мышечных тканей скумбрии японской и терпуга северного одноперого существенно не отличаются, однако в скумбрии выше содержание гистидина и изолейцина. Общее количество моно- и полиненасыщенных жирных кислот (ЖК) в скумбрии составило 63,99%, а в терпуге их содержание выше – 75,56%. Из мононенасыщенных ЖК липидов скумбрии и терпуга преобладает олеиновая, которой в терпуге почти в два раза больше, чем в скумбрии. Терпуг более богат полиненасыщенными ЖК, содержание которых составляет 35,45%. В скумбрии их содержание ниже – 25,60%. Липиды скумбрии и терпуга имеют достаточно высокие коэффициенты метаболизации – 1,57 и 1,50 соответственно. Соотношение ω-6 : ω-3 ЖК у скумбрии составляет 1 : 5, у терпуга 1 : 3, т. е. содержание ω-3 ЖК по отношению к ω-6 завышено, что необходимо учитывать при производстве пищевых продуктов из данного сырья, комбинируя его с другим для сбалансированности жирнокислотного состава. Результаты исследования показывают перспективность использования скумбрии и терпуга при производстве широкого спектра рыбопродукции, в том числе полуфабрикатов. Technochemical properties of Japanese mackerel (Scomber japonicas) and Atka mackerel (Pleurogrammus monopterygius) were investigated. It is established that Japanese mackerel and Atka mackerel (terpug) are valuable food raw materials rich in biologically valuable protein, which contains all the essential amino acids. Amino acid compositions of the muscle tissue of mackerel Japanese and the terpug not differ significantly, however, mackerel higher content of histidine and isoleucine. The total amount of mono-and polyunsaturated fatty acids (FA) in mackerel was 63,99%, and in terpug their content is higher – 75,56%. Among monounsaturated FA of lipids mackerel and terpug dominated by oleic, which in terpug is almost two times more than in mackerel. Terpug is more rich in polyunsaturated FA, the content of which is 35,45%. In mackerel their content below – 25,60%. Lipids mackerel and Atka mackerel have relatively high coefficients of metabolization and 1,57 and 1,50 respectively. The ratio of ω-6 : ω-3 FA from mackerel is 1 : 5, the Atka mackerel 1 : 3, i. e., the content of ω-3 FA in relation to ω-6 are too high, it is necessary to consider in the production of food products from this raw material, combining it with others to balance the fatty acid composition. The results of the study show the prospects of using mackerel and terpug in the production of a wide range of fish products, including semi-finished products.

The nutrient composition of 15 commercially available microalgae powders of Arthrospira platensis, Chlorella pyrenoidosa and vulgaris, Dunaliella salina, Haematococcus pluvialis, Tetraselmis chuii, and Aphanizomenon flos-aquae was analyzed. The Dunaliella salina powders were characterized by a high content of carbohydrates, saturated fatty acids (SFAs), omega-6-polyunsaturated fatty acids (n6-PUFAs), heavy metals, and α-tocopherol, whereas the protein amounts, essential amino acids (EAAs), omega-3-PUFAs (n3-PUFAs), vitamins, and minerals were low. In the powder of Haematococcus pluvialis, ten times higher amounts of carotenoids compared to all other analyzed powders were determined, yet it was low in vitamins D and E, protein, and EAAs, and the n6/n3-PUFAs ratio was comparably high. Vitamin B12, quantified as cobalamin, was below 0.02 mg/100 g dry weight (d.w.) in all studied powders. Based on our analysis, microalgae such as Aphanizomenon and Chlorella may contribute to an adequate intake of critical nutrients such as protein with a high content of EAAs, dietary fibers, n3-PUFAs, Ca, Fe, Mg, and Zn, as well as vitamin D and E. Yet, the nutritional value of Aphanizomenon flos-aquae was slightly decreased by high contents of SFAs. The present data show that microalgae are rich in valuable nutrients, but the macro- and micronutrient profiles differ strongly between and within species.
