Purpose Stirred yoghurt made using probiotic bacteria which are usually called Rayeb milk in the Arab countries is one of the most important functional fermented milk products. Tamr (dried dates) is commonly consumed in various parts of the world and is believed to represent a vital component of the diet in the Arab world. Tamr and honey characterize with high nutritional and healthful benefits. The purpose of this paper is to manufacture functional fermented dairy food (Rayeb milk) which has the nutritional and health effects of goat’s milk, Tamr, honey and probiotic. Design/methodology/approach Rayeb milk was made from goat’s milk fortified with Tamr (10 and 15 percent) with or without honey (1, 2, and 3 percent) using ABT culture (S. thermophiles, L. acidophilus, and Bifidobacterium). Samples of Rayeb milk were studied for their chemical composition, starter bacteria populations, and sensory attributes during 14 days of storage period. Findings Supplementation of goat’s milk with Tamr and honey decreased saturated fatty acids concentrations in Rayeb milk. The levels of carbohydrate, total solids, dietary fiber, ash, total protein (TP), unsaturated fatty acids, omega-3, omega-6, omega-9 fatty acids and antioxidants activity were higher in Rayeb milk contained Tamr and honey than those of control. Also, numbers of probiotic bacteria (L. acidophilus and Bifidobacterium) greatly increased in Rayeb milk supplemented with Tamr and honey. The recommended level of 107 cfu.g-1 of bifidobacteria as a probiotic was exceeded for these treatments. Adding Tamr and honey highly improved the sensory attributes of Rayeb milk. Originality/value Adding 10 percent Tamr with 3 percent honey or 15 percent Tamr with 1 or 2 percent honey to goat’s milk highly improved the nutritional, healthy and sensory properties of Rayeb milk.

Исследованы показатели качества молока, полученного от коз русской породы Поволжского региона, с целью создания на его основе кулинарной продукции для людей с непереносимостью коровьего молока. Содержание массовой доли жира в молоке коз по разным месяцам лактации составило от 3,77 до 4,07%. Максимальные значения по данному показателю отмечены в первые два и последние два месяца лактации, что связано с кормовыми факторами. Содержание в цельном козьем молоке: лактозы 4,45–4,63%; СОМО в пределах нормы; плотность 29°А; титруемая кислотность 16–20°Т; соматических клеток менее 500 тыс./см3; ненасыщенных жирных кислот от 27,918 до 28,590%; коэффициент соотношения ненасыщенных и насыщенных жирных кислот в пределах от 0,414 до 0,437. Исследованное козье молоко использовано для разработки кулинарной продукции – блинов и оладий для диетического питания. В блинах и оладьях на козьем молоке с кукурузной мукой отмечено снижение белков на 22,0 и 24,6%, увеличение в 3,25 раза количества жиров и на 2,0 и 2,3% углеводов соответственно. Разработанные рецептуры диетических кулинарных изделий позволяют расширить ассортимент пищевых продуктов лечебно-профилактического назначения и массового потребления в целом. The indicators of quality of the milk received from goats of the Russian breed of the Volga region for the purpose of creation on its basis of culinary production for the people suffering from intolerance of cow’s milk are investigated. The content of the mass fraction of fat in goat milk for different lactation months ranged from 3,77 to 4,07%. The maximum values on this indicator are noted the first two and last two months of lactation that it is connected with fodder factors. Content in whole goat’s milk: 4,45–4,63% of lactose; SOMO within norm; density of 29°A; titratable acidity 16–20°T; somatic cell count less than 500 thousand/cm3; unsaturated fatty acids from 27,918 to 28,590%; the ratio of unsaturated and saturated fatty acids ranged from 0,414 up to 0,437. The studied goat milk was used to develop culinary products – the pancakes and fritters for dietary nutrition. In pancakes and fritters on goat milk with corn flour there was a decrease in proteins by 22 and 24,6%, an increase of 3,25 times the amount of fat and 2,0 and 2,3% of carbohydrates, respectively. The developed recipes of dietary culinary products will allow expand the range of food products for therapeutic and preventive purposes and mass consumption in general.

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.

Yogurt was prepared from goat's milk, supplemented with aronia juice and blueberry juice. The dynamics of acidification, number of lactic acid bacteria, and fatty acids composition were investigated. Yogurt from goat's milk, supplemented with aronia juice and blueberry juice, coagulated at a lower acidity and faster than natural yogurt. The numbers of lactic acid bacteria in supplemented yogurts were higher compared to control samples. The addition of aronia and blueberry juices increased the amount of unsaturated fatty acids in yogurt by 6.9% and 8.5%, respectively. Polyunsaturated fatty acids increased by 11.2% in yogurt with aronia juice in comparison with natural yogurt.

Purpose Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls. Design/methodology/approach This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD. Findings According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively. Originality/value PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.

ABSTRACTHuman fungal infections represent a therapeutic challenge. Although effective strategies for treatment are available, resistance is spreading, and many therapies have unacceptable side effects. A clear need for novel antifungal targets and molecules is thus emerging. Here, we present the identification and characterization of the plant-derived diyne-furan fatty acid EV-086 as a novel antifungal compound. EV-086 has potent and broad-spectrum activityin vitroagainstCandida,Aspergillus, andTrichophytonspp., whereas activities against bacteria and human cell lines are very low. Chemical-genetic profiling ofSaccharomyces cerevisiaedeletion mutants identified lipid metabolic processes and organelle organization and biogenesis as targets of EV-086. Pathway modeling suggested that EV-086 inhibits delta-9 fatty acid desaturation, an essential process inS. cerevisiae, depending on the delta-9 fatty acid desaturaseOLE1. Delta-9 unsaturated fatty acids—but not saturated fatty acids—antagonized the EV-086-mediated growth inhibition, and transcription of theOLE1gene was strongly upregulated in the presence of EV-086. EV-086 increased the ratio of saturated to unsaturated free fatty acids and phosphatidylethanolamine fatty acyl chains, respectively. Furthermore, EV-086 was rapidly taken up into the lipid fraction of the cell and incorporated into phospholipids. Together, these findings demonstrate that EV-086 is an inhibitor of delta-9 fatty acid desaturation and that the mechanism of inhibition might involve an EV-086–phospholipid. Finally, EV-086 showed efficacy in a guinea pig skin dermatophytosis model of topicalTrichophytoninfection, which demonstrates that delta-9 fatty acid desaturation is a valid antifungal target, at least for dermatophytoses.

ABSTRACTToxoplasma gondii, an obligate intracellular parasite replicating in mammalian cells within a parasitophorous vacuole (PV), is an avid scavenger of lipids retrieved from the host cell. Following lipid uptake, this parasite stores excess lipids in lipid droplets (LD). Here, we examined the lipid storage capacities ofToxoplasmaupon supplementation of the culture medium with various fatty acids at physiological concentrations. Supplemental unsaturated fatty acids (oleate [OA], palmitoleate, linoleate) accumulate in large LD and impair parasite replication, whereas saturated fatty acids (palmitate, stearate) neither stimulate LD formation nor impact growth. Examination of parasite growth defects with 0.4 mM OA revealed massive lipid deposits outside LD, indicating enzymatic inadequacies for storing neutral lipids in LD in response to the copious salvage of OA.Toxoplasmaexposure to 0.5 mM OA led to irreversible growth arrest and lipid-induced damage, confirming a major disconnect between fatty acid uptake and the parasite's cellular lipid requirements. The importance of neutral lipid synthesis and storage to avoid lipotoxicity was further highlighted by the selective vulnerability ofToxoplasma, both the proliferative and the encysted forms, to subtoxic concentrations of the acyl coenzyme A:diacylglycerol acyltransferase 1 (DGAT1) pharmacological inhibitor T863. T863-treated parasites did not form LD but instead built up large membranous structures within the cytoplasm, which suggests improper channeling and management of the excess lipid. Dual addition of OA and T863 to infected cells intensified the deterioration of the parasite. Overall, our data pinpointToxoplasmaDGAT as a promising drug target for the treatment of toxoplasmosis that would not incur the risk of toxicity for mammalian cells.

ABSTRACT Across all kingdoms of life, cells store energy in a specialized organelle, the lipid droplet. In general, it consists of a hydrophobic core of triglycerides and steryl esters surrounded by only one leaflet derived from the endoplasmic reticulum membrane to which a specific set of proteins is bound. We have chosen the unicellular organism Dictyostelium discoideum to establish kinetics of lipid droplet formation and degradation and to further identify the lipid constituents and proteins of lipid droplets. Here, we show that the lipid composition is similar to what is found in mammalian lipid droplets. In addition, phospholipids preferentially consist of mainly saturated fatty acids, whereas neutral lipids are enriched in unsaturated fatty acids. Among the novel protein components are LdpA, a protein specific to Dictyostelium , and Net4, which has strong homologies to mammalian DUF829/Tmem53/NET4 that was previously only known as a constituent of the mammalian nuclear envelope. The proteins analyzed so far appear to move from the endoplasmic reticulum to the lipid droplets, supporting the concept that lipid droplets are formed on this membrane.

AbstractIn this study, varying concentrations of polyunsaturated fatty acids in goat’s milk were obtained by supplementing goat feed rations with maize dried distillers grains with solubles (DDGS). In comparison to the control group, the milk of goats that received DDGS contained about 25% more polyunsaturated fatty acids, 30% more conjugated linoleic acid (CLA), and had more favorable values of the atherogenic and thrombogenic indices. The diverse composition of fatty acids present in the goat’s milk correlated with the olfactory perception of the milk and its volatile compound profile. The level of unsaturated fatty acids significantly affected the odors detected in the processed goat’s milk. The volatile compound profile of the milk was mostly differentiated by the concentrations of aldehydes (hexanal and furfural) and furanones (furaneol), which exceeded their odor threshold values. The total concentration of identified aldehydes was highest in pasteurized milk samples from the goats of the experimental group, as a result of heating. Furfural was found in pasteurized samples of both the control and experimental milk at concentrations exceeding its odor threshold (3 mg·kg−1). Feeding goats with DDGS did not change the animal, cooked, dairy fat, lack of freshness, light-oxidized, or overall dairy flavors of the raw milk. After pasteurization, milk from goats fed with DDGS retained its characteristic animal odor and gained a very intense cooked flavor.

Sunflower seeds are highly popular in food mixes, especially biscuits and are thought to be nutritionally beneficial. These seeds are rich in healthy fats, useful plant compounds and many vitamins and minerals. The present study was conducted to investigate the effect of the incorporation of irradiated sunflower flour on the physico-chemical and sensory properties of biscuits during the storage period. The physical and chemical properties of wheat flour with 72% extraction, nonirradiated sunflower flour and sunflower flour irradiated with 5 kGy and 10 kGy were estimated. Additionally, the physical, chemical and sensory properties of extracted oils from the biscuits were also evaluated during storage periods of two and four months. The refractive index, peroxide value and iodine value decreased as the storage period increased, while acids such as oleic acid and the acid value increased slowly and gradually. Additionally, the fatty acids of the oils extracted from biscuits during storage were high in unsaturated fatty acids at the beginning of storage. After two and four months of storage, an increase in saturated fatty acids and a decrease in unsaturated fatty acids was observed. The results showed that the overall acceptability of sunflower flour biscuits irradiated at a dose of 10 kGy was highest, while the control biscuits had the lowest acceptability after 4 months of storage. It was concluded that the substitution of up to 10% of wheat flour with nonirradiated or irradiated sunflower flour can be a good method for food product development due to the ability of sunflower flour to improve the nutritional value and overall acceptability of biscuits.
