Main technological and chemical characteristics of small-sized shrimps Pandalus borealis, P. goniurus and krill Euphausia superba are presented. The main processes of this kind of shrimp processing are described, with usage of its own complex of proteinases to produce autoproteolysis products. Lysates of these shrimps have high nutritional value comparable with the value of low-fat cottage cheese, though the shrimp lysate protein is a completely animal protein similar to beef one. As a source of low-fat protein, the shrimp lysates belong to the category of specialized and functional food and food ingredients; they also can de considered as the source of omega-3 fatty acids and astaxanthin. Volatile components of the shrimp lysates contain 30 compounds responsible for taste and aroma properties of crabs and shrimps, as thiran, methylthiran, dimethyldisulfide, thioacetic acid, 2-mercaptopropanoic acid, etc. Safety of shrimps and their lysates is provided by low content of organochlorine compounds, radionuclides, toxic elements and low values of microbiological parameters, below of the maximum permissible levels. The shrimp lysates are suitable for using in manufacture of emulsion and pasty products with high commodity properties, classified as gastronomic products with high taste and nutritional value.

Functional food is a whole ingredient or a part of food that used as food for specific therapeutic purposes. It is divided into two wide categories: Conventional and modified functional foods. Conventional functional Foods are composed of natural or whole-food ingredients that provide functional substances while modified functional is food or food products in which add additional ingredients for specific health purposes. Plant-based food such as fruits, vegetables, herbs, cereals, nuts and beans contain vitamins, minerals, fiber, omega-3 fatty acids, antioxidants and phenolic compounds that play a functional role in the human body against chronic diseases including cancer, cardiovascular and GIT-related disease. Some other foods or food products like juices, dairy products, fortified eggs and seafood are composed of functional components. Fish contain omega-3 fatty acids (EPA and DHA) that are played a functional role in heart health and brain development.

Dyslipidemia leads to atherosclerosis which is a risk factor for cardiovascular diseases. Edamame contains omega-3 fatty acids and phytochemical components such as isoflavones, sterols and saponins, and also high in fiber content. Edamame has been proved to have ability to decrease LDL cholesterol level. This research aims to analyze the comparison of edamame flour based low fat enteral formula with commercial low fat formula. This was a descriptive comparatif research design. Data collection was done by doing calculations on nutrient content and bioavailability protein, also organoleptic quality of low fat enteral formula with edamame flour substitution. The result showed that fat content of modified formula was 26.4% of total energy requirement and the value had met dietary requirement for dyslipidemia diet which is not more than <30% of total energy requirement. Type of fat in this formula largely contans unsaturated fats derived from omega-3 fatty acids of soy edamame and omega-9 fatty acids from olive oil. The value of  protein bioavailability which was shown from Amino Acid Score was 32.18, Theoretical Digestibility was 89.27, Net Protein Utilization was 28.73, Protein Worth of Eggs was 16.77, and Protein Eficiency Ratio was 4.51. The result of hedonic quality test showed that the color of low fat enteral formula with edamame flour substitution was light brown, the taste was sweet, the smell was typical edamame aroma, and had liquid consistency. Based on the comparison of commercial enteral formula with non-commercial enteral formula based on edamame flour, it can be concluded that edamame based flour enteral formula can be recommended as a non-commercial enteral formula for patients with dyslipidemia replacing commercial formula.

<p>With global consumer demand shifting towards the consumption of healthier foods, it is crucial to discover new sources of edible plants with high nutritional value and low cost. Unique weeds such as purslane have the potential to be used as an untapped source of unconventional food with diverse nutrients and beneficial bioactive properties. Inflammation can cause oxidative stress related diseases including cardiovascular disorders, aging and cancer. One key nutrient of purslane is omega-3 with potential of inhibitory properties against inflammatory and estrogenic mediators. Purslane is known to be a rich source of a-linolenic acid, 18:3 ω-3, an essential fatty acid, carotenes, antioxidants and minerals. However, the precise mechanism of action of its individual components in disease prevention is unknown. This review provides a summary on the role of purslane bioactives, particularly omega-3 fatty acids as one of purslane’s main constituents with potential of anti-inflammatory and anti-estrogenic properties. The discovery of new sources of plants rich in omega-3 fatty acids may be a useful strategy in utilizing natural alternative sources of foods that can enhance human health and wellbeing.</p>

Recently, algae have received considerable interest as one of the most promising feedstocks suitable for animal feed production due to their fast growth, less nutrient requirements and their ability to produce primary and secondary metabolites with high-added value. Different strategies were applied to improve both biomass and metabolites productivities aiming to produce highquality biomass with low cost and high nutritional value. Tetraselmis subcoliformis QUCCCM50, a local marine green alga presenting fast growth, high metabolites content and easy to harvest, was selected as a candidate for feed production. Three different stress conditions were applied to enhance its potential to produce high-value products such as Nitrogen or Phosphorus depletion and high salinity of 100ppt. An assessment of the growth properties and biomass productivity was performed during the growth. After 15 days of cultivation using tubular photobioreactors, the biomass was subjected to metabolites characterization and fatty acids methyl ester profiling. Results showed that the three stress conditions present different impacts on biomass productivity and, lipid quantity and quality. Cultivation under 100 ppt led to the highest increase in lipid content. This culture condition led to 25% increase of the omega-3 fatty acids with the appearance of the docosahexaenoic acid (DHA) and a remarkable increase of the alpha-linolenic acid, comparatively to the control. The enrichment of the Tetraselmis subcoliformis’ biomass in terms of omega-3 fatty acids enhance its nutritional value and make it very suitable for animal feed production. The optimized culture conditions obtained from the current study will be applied at large scale to enhance the quality of the biomass towards omega-3 enriched animal feed supplement production, and hence support achieving food security in the State of Qatar.

Primary hyperlipidaemia in Schnauzer is characterized by increased plasma triglycerides (TG) and/or total cholesterol (TC) concentration and is associated with an increased risk of developing pancreatitis, insulin resistance and seizures. In humans, omega-3 fatty acids in addition to a low-fat diet can be used to reduce TG and TC. This study evaluated the therapeutic efficacy of omega-3 fatty acids associated to a diet management with two different fat content in Schnauzer with primary hyperlipidaemia. Eighteen dogs with primary hyperlipidaemia were divided into two groups: group 1, n = 10, 8 females, 2 males, age (mean ± standard deviation) of 7.13 ± 2.70 years and body weight (BW) (mean ± standard deviation) of 7.25 ± 1.22 kg were treated with fish oil (approximately 730 mg/day of omega-3) associated with a low-fat and low-calorie diet (approximately 24g of fat/1000 kcal) for 90 days (T90); and group 2, n = 8 dogs, 6 females, 2 males, with 7.0 ± 1.77 years old and average BW of 8.36 ± 1.51 kg, treated with fish oil (approximately 730 mg/day of omega-3) and maintenance diet with moderate amount of fat (approximately 33g of fat/1000 kcal) for 90 days. Plasma TG and TC concentrations and lipoprotein (LP) profile (VLDL, LDL, HDL) were evaluated before and after treatment. TG and TC serum concentrations, expressed in mg/dL (mean ± standard deviation), before and after treatment in group 1 were: TG = 391.30 ± 487.86 (T0) and 118.7 ± 135.21 (T90); TC = 308.2 ± 63.06 (T0) and 139 ± 36.91 (T90). As for group 2, TG = 391.63 ± 336.89 (T0) and 250.75 ± 211.56 (T90); TC = 257.25 ± 92.88 (T0) and 207.25 ± 63.79 (T90). A reduction (p<0.05) of TG and TC was observed in both groups. The distribution of TG and TC among LP was not different between the pre (T0) and post treatment (T90) periods. After 90 days of treatment, the administration of omega-3 fatty acids, associated with a low-fat or maintenance diet reduced triglyceridemia and cholesterolemia without altering LP profile. The current investigation shows that both therapies were effective in reducing plasma TC and TG concentrations without altering LP profile.

Purslane (Portulaca oleraceae L.) is a widespread weed, which is highly appreciated for its high nutritional value with particular reference to the content in omega-3 fatty acids. In the present study, the nutritional value and chemical composition of purslane plants in relation to plant part and harvesting stage were evaluated. Plants were harvested at three growth stages (29, 43 and 52 days after sowing (DAS)), while the edible aerial parts were separated into stems and leaves. Leaves contained higher amounts of macronutrients than stems, especially at 52 DAS. α-tocopherol was the main isoform, which increased at 52 DAS, as well total tocopherols (values were in the ranges of 197–327 μg/100 g fresh weight (fw) and 302–481 μg/100 g fw, for α-tocopherol and total tocopherols, respectively). Glucose and fructose were the main free sugars in stems and leaves, respectively, whereas stems contained higher amounts of total sugars (values were ranged between 0.83 g and 1.28 g/100 g fw). Oxalic and total organic acid content was higher in leaves, especially at the last harvesting stage (52 DAS; 8.6 g and 30.3 g/100 g fw for oxalic acid and total organic acids, respectively). Regarding the fatty acid content, stems contained mainly palmitic (20.2–21.8%) and linoleic acid (23.02–27.11%), while leaves were abundant in α-linolenic acid (35.4–54.92%). Oleracein A and C were the major oleracein derivatives in leaves, regardless of the harvesting stage (values were in the ranges of 8.2–103.0 mg and 21.2–143 mg/100 g dried weight (dw) for oleraceins A and C, respectively). Cytotoxicity assays showed no hepatotoxicity, with GI50 values being higher than 400 μg/mL for all the harvesting stages and plant parts. In conclusion, early harvesting and the separation of plant parts could increase the nutritional value of the final product through increasing the content of valuable compounds, such as omega-3 fatty acids, phenolic compounds and oleracein derivatives, while at the same time, the contents of anti-nutritional compounds such as oxalic acid are reduced.

The interactive potential of three known peroxisome proliferators, omega-3 fatty acids, clofibrate and di(2-ethylhexylphthalate (DEHP), was evaluated in male weanling Wistar rats for the effect on peroxisomal beta-oxidation. Omega-3 fatty acids were supplied by menhaden oil which was fed in six regimens: low fat (5% w/w), low fat and clofibrate (0.3% w/w) or DEHP (0.25% w/w), high fat (20% w/w), high fat and clofibrate or DEHP in the aforementioned concentrations. Induction of peroxisomal beta-oxidation was measured by changes in liver-to-body weight ratio, fatty acyl-CoA oxidase (FAO) activity, and peroxisomal bifunctional enzyme (PBE) quantity. Analysis of transformed data indicated a less than additive response in FAO activity with no deviation from additivity seen with liver-to-body ratios and PBE.
