Chlamydomonas reinhardtii is a green microalgae used as a model organism associated with biotechnological applications, yet its nutritional value has not been assessed. This study investigates the nutritional capacity of C. reinhardtii as an additional value for this species beyond its known potential in biofuels and bio-products production. The composition of key nutrients in C. reinhardtii was compared with Chlorella and Spirulina, the species widely regarded as a superfood. The results revealed that the protein content of C. reinhardtii (46.9%) was comparable with that of Chlorella (45.3) and Spirulina (50.4%) on a dry weight basis. C. reinhardtii contained all the essential amino acids with good scores based on FAO/WHO values (0.9–1.9) as in Chlorella and Spirulina. Unsaturated fatty acids predominated the total fatty acids profile of C. reinhardtii were ~74 of which ~48% are n-3 fatty acids. Alpha-linolenic acid (ALA) content in C. reinhardtii (42.4%) was significantly higher than that of Chlorella (23.4) and Spirulina (0.12%). For minerals, Spirulina was rich in iron (3.73 mg/g DW) followed by Chlorella (1.34 mg/g DW) and C. reinhardtii (0.96 mg/g DW). C. reinhardtii, unlike the other two species, consisted of selenium (10 µg/g DW), and had a remarkably lower heavy metal load. Moreover, C. reinhardtii contained relatively high concentrations of chlorophyll (a + b) and total carotenoids (28.6 mg/g DW and 6.9 mg/g DW, respectively) compared with Chlorella (12.0 mg/g DW and 1.8 mg/g DW, respectively) and Spirulina (8.6 mg/g DW and 0.8 mg/g DW, respectively). This study confirms that, based on its nutrient credentials, C. reinhardtii has great potential as a new superfood or ingredient for a food supplement.

Armoured crickets are an important food source in some parts of Zimbabwe. These insects are abundant in some regions but however, they are under utilised and not much is known about their nutritional value. The aim of this study was to determine the nutritional profile of the armoured cricket (Acanthoplus discoidalis). Armoured crickets were collected from a structured sampling framework in Mbire district Mashonaland Central province of Zimbabwe. Removal of the head and thorax, degutting and boiling were done. A proximate analysis was carried out followed by mineral, amino acid and fatty acid profiling of the prepared insects. Analyses were done on a dry basis. A. discoidalis contained 69.2% protein, 16.8% fat, 8.6% ash, 1.2% carbohydrate, 4.2% chitin and 454.3 Kcal/100 g energy. A 100 g dry weight quantity of insect contains 11.48 mg iron which is enough to meet the required daily intake of 10.0-20 mg/day for an adult. The zinc (4.37 mg/100 g dry weight) and phosphorus (491.4 mg/100 g dry weight) content in A. discoidalis almost meets the reference nutrient intake for adults. Essential amino acids, leucine (60.7 mg/g protein) had the highest concentration followed by phenylalanine+tyrosine (59.3 mg/g protein), valine (48.4 mg/g protein), lysine (46.7 mg/g protein), threonine (37.4 mg/g protein), isoleucine (26.4 mg/g protein), methionine+cysteine (20.9 mg/g protein) and histidine (16.5 mg/g protein) the least concentration. In total, 9 saturated fatty acids were determined of which stearic acid and palmitic acid had the highest concentrations of 2,034.5 mg/100 g and 2,005.3 mg/100 g respectively. Four mono unsaturated fatty acids were determined of which oleic acid and palmitoleic acid had the highest concentrations of 361.4 mg/100 g and 305.2 mg/100 g respectively. Four poly-unsaturated fatty acids were determined of which eicosapentaenoic and α-linolenic acid had the highest concentrations of 1,598.0 mg/100 g and 185.6 mg/100 g respectively. A. discoidalis is good source of protein, the minerals iron, zinc and phosphorus, some essential amino acids and poly-unsaturated fatty acids.

n the current paper, we aimed to analyze the way in which packing (different polyethylene types) influence the quality of pasteurized melange during storage, packing being realized in units of 1 kg (Tetra Pak) (batch Lexp-1) and units of 5 kg (Bag in box) (batch Lexp-2). Products were stored during a period of 28 days at a temperature of +4�C, qualitative determinations being realized in first day (day 0), at 7 days, at 14 days, 21 days and in day 28 of storage. Were effectuated a sensorial examination and chemical analysis were was established the content in dry matter (%), water (%), proteins (%), content in essential amino acids (isoleucine, methionine, tryptophan, phenylalanine) and non-essential amino acids (alanine, histidine, glycine, serine) (mg/100g) as well as the content in lipids (%) establishing their profile by identification of some saturated fatty acids (16:0 mg/100g and 18:0 mg/100g) and unsaturated fatty acids (16:1 mg/100g and 18:1 mg/100g). After sensorial examinations, the first modifications were observed at the checking effectuated in day 21 for batch Lexp-2, the obtained score being of 18 points, and at checking effectuated in day 28 was given a score of 18 points for melange belonging to batch Lexp-1 and only 14 points for melange from batch Lexp-2. Differences were recorded also in case of chemical composition of products, so for protein content at batch Lexp-1 in first checking day was obtained a mean of 12.730�0.24% and at batch Lexp-2 12.614�0.22%. Differences between those two batches were insignificant (p[0.05). In case of fat content, at the end of storage period was obtained a mean of 11.256�0.06% for batch Lexp-1 and 11.244�0.11% for batch Lexp-2, differences being insignificant (p [ 0.05). Regarding the profile of amino acids and fatty acids, the mean values obtained during whole storage period oscillated from one stage to another, but the differences between those two batches were insignificant (p [ 0.05). Pasteurized egg melange suffers certain sensorial modifications during storage, especially on consistency and colouring, modifications which are accentuated mainly by storage conditions. Type of polyethylene utilized for this product hadn�t influenced the nutritive qualities of product.

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.

Penaeus japonicus is an important marine shrimps resource in China. In order to evaluate the nutritional value, the contents of general nutritional compositions, amino acids and fatty acids in muscle were compared between wild and farmed P. japonicus. The contents of muscle moisture and crude protein, fat and ash in wild P. japonicus were 77.16%, 17.74%, 2.08% and 1.79%, and those in farmed P. japonicus were 78.02%, 17.26%, 2.04% and 1.63%, respectively. The essential amino acids (EAA) in wild and farmed P. japonicus were 23.25% and 22.43%, respectively. The amino acid score of essential amino acids were higher than 100 except Leu and Trp, so the protein of P. japonicus has a well-balanced amino acid composition. Wild P. japonicus has more unsaturated fatty acids (64.05%) than farmed group (60.34%). Higher n-3 polyunsaturated fatty acids (PUFAs), eicosapentainoic acids (EPA, 20:5 n-3), docosahexaenoic acids (DHA, 22:6 n-3) contents and lower C16:0, C20:0, C18:1, C18:2, C18:3 levels were detected in the wild group. Values of n-6/n-3 in muscle of farmed and wild P. japonicus were 0.30 and 0.23 respectively, which were both significantly lower than the maximum value (4.0) recommended by UK Department of Health (HMSO, 1994), while Values of the PUFA/SFA ratio of two groups were 0.60 and 0.74 higher than the minimum value (0.45) recommended by HMSO. Thus the muscle of farmed and wild P. japonicus are both healthy and safe, and the the muscle of wild P. japonicus is more beneficial to human health.

AbstractMany invertebrates have an unexpected nutraceutical potential and are of nutritional or ethnomedicinal significance to many tribals throughout the world. The giant pill-millipedes of the genus Arthrosphaera are traditionally used as natural medicines by tribals in the Western Ghats of India. In this study, two species of pill-millipedes (Arthrosphaera fumosa and A. magna) were subjected to proximate and biochemical analysis to ascertain their nutritional potential. Bodies of A. fumosa and A. magna (after removal of their intestines) had a low protein content (8-15%) and high quantity of carbohydrates (40-41%). They were rich in many essential elements, especially in calcium. The essential amino acids of pillmillipedes were in high quantities. The level of glycine was the highest, followed by lysine and serine. The fatty acid methyl esters (FAMEs) of males and females consist of high quantities of unsaturated fatty acids. The mono-unsaturated fatty acids were more abundant than poly-unsaturated fatty acids. Palmitic and oleic acids were dominant saturated and unsaturated fatty acids, respectively. The study has revealed for the first time that pill-millipedes of the Western Ghats of India constitute a good source of essential minerals, essential fatty acids, and essential amino acids. Being valuable contributors of organic manure by processing recalcitrant plant lignocellulosic wastes, pill-millipedes become part and parcel of organic farming as well as future nutraceutical sources.

Bee pollen is a nutrient-rich food that meets the nutritional requirements of honey bees and supports human health. This study aimed to provide nutritive composition data for 11 popular bee pollen samples (Brassica napus (Bn), Bidens pilosa var. radiata (Bp), Camellia sinensis (Cs), Fraxinus griffithii (Fg), Prunus mume (Pm), Rhus chinensis var. roxburghii (Rc), Bombax ceiba (Bc), Hylocereus costaricensis (Hc), Liquidambar formosana (Lf), Nelumbo nucifera (Nn), and Zea mays (Zm)) in Taiwan for the global bee pollen database. Macronutrients, such as carbohydrates, proteins, and lipids, were analyzed, which revealed that Bp had the highest carbohydrate content of 78.8 g/ 100 g dry mass, Bc had the highest protein content of 32.2 g/ 100 g dry mass, and Hc had the highest lipid content of 8.8 g/ 100 g dry mass. Only the bee pollen Hc completely met the minimum requirements of essential amino acids for bees and humans, and the other bee pollen samples contained at least 1–3 different limiting essential amino acids, i.e., methionine, tryptophan, histidine, valine, and isoleucine. Regarding the fatty acid profile of bee pollen samples, palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic acid (C18:3) were predominant fatty acids that accounted for 66.0–97.4 % of total fatty acids. These data serve as an indicator of the nutritional quality and value of the 11 bee pollen samples.

Soy is one of the most valuable agricultural crops, the protein composition of which includes essential amino acids, similar in composition to animal proteins, and fat in its composition predominates sunflower and olive. Comparative study of biochemical composition of soybean seeds of the Northern ecotype depending on varietal characteristics and meteorological conditions of the growing season. Perennial field experiments (2002-2019) were carried out on the experimental field of the plant growing laboratory of RSAU–MSHA named after K. A. Timiryazev. The objects of study were soybean varieties of the Northern ecotype – Svitlaya, Mageva, and Okskaya. Biochemical analysis of seeds was performed in the laboratory of research of technological properties of agricultural materials FSBSI FSAC VIM. The seeds of Northern ecotype soybean varieties contain 40.6-41.2 % protein and 19.4-19.9 % fat. Protein is characterized by a high content of sum of essential amino acids (63.10-63.98 %), including – histidine (7.2–7.7 %), lysine (7.7–7.8 %), tryptophan (by 4.6–4.9 %), arginine (8.4–8.8%), threonine (more than 4.0 %), phenylalanine (to 3.5 %). It was established that in comparison with traditional (southern) varieties, the seed fat of soybean varieties of the Northern ecotype is characterized by a higher content of palmitic acid (11.0–11.3 %) and significantly lower content of oleic acid (10.0–12.0 %). At the same time, according to the content and ratio of polyunsaturated fatty acids (linoleic and linolenic), it is close to the fat of food grades. Under conditions of excessive moisture, a high content of saturated palmitic fatty acid was observed, and in arid conditions – unsaturated fatty acids – oleic, linoleic and linolenic. Analysis of the quantitative and qualitative components of protein and fat of soybean varieties of Northern ecotype gives grounds to recommend their use not only for feed, technical, but also for food purposes.
