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 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.

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.

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.

Background: Research efforts have focused on the evaluation of the bioactive quality of animal products (milk, cheese, meat, and other by-products) contrasting various feeding strategies coming from different ecological zones. The study aimed to describe the fatty acids (FA), polyphenols (P), bioactive compounds (BC), and antioxidant activity (AA) of goat’s milk. Methods: Dairy goats were fed with five systems: (1) Grazing; (2) conventional diet (CD); (3) CD + 10% of Acacia farnesiana (AF) pods; (4) CD + 20% AF; and (5) CD + 30% AF. The fatty acid profile, health promoting and thrombogenic indexes were calculated. Milk extracts were evaluated by HPLC to determent phenolic compounds (gallic, caffeic, chlorogenic, and ferulic acids, catechin, epicatechin, and quercetin). Antioxidant activity of goat’s milk extract was evaluated using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•), oxygen radical absorbance capacity (ORAC), and the ferric reducing antioxidant power (FRAP) assays. Results: Conventional diet showed the highest content of polyunsaturated fatty acids while grazing showed the best n-6:n-3 and the linoleic:alpha linolenic acid ratio. Similarly, grazing and AF boosted the polyphenol content. Conclusions: Acacia farnesiana inclusion in the goats’ diets increased the presence of bioactive compounds and the antioxidant activity while diminishing the cholesterol content of goat’s milk.

Goat's Milk

Goat’s milk is a rich source of bioactive compounds (peptides, conjugated linoleic acid, short chain fatty acids, monounsaturated and polyunsaturated fatty acids, polyphenols such as phytoestrogens and minerals among others) that exert important health benefits. However, goat’s milk composition depends on the type of food provided to the animal and thus, the abundance of bioactive compounds in milk depends on the dietary sources of the goat feed. The metabolic impact of goat milk rich in bioactive compounds during metabolic challenges such as a high-fat (HF) diet has not been explored. Thus, we evaluated the effect of milk from goats fed a conventional diet, a conventional diet supplemented with 30% Acacia farnesiana (AF) pods or grazing on metabolic alterations in mice fed a HF diet. Interestingly, the incorporation of goat’s milk in the diet decreased body weight and body fat mass, improved glucose tolerance, prevented adipose tissue hypertrophy and hepatic steatosis in mice fed a HF diet. These effects were associated with an increase in energy expenditure, augmented oxidative fibers in skeletal muscle, and reduced inflammatory markers. Consequently, goat’s milk can be considered a non-pharmacologic strategy to improve the metabolic alterations induced by a HF diet. Using the body surface area normalization method gave a conversion equivalent daily human intake dose of 1.4 to 2.8 glasses (250 mL per glass/day) of fresh goat milk for an adult of 60 kg, which can be used as reference for future clinical studies.

Cheese Production

The use of small ruminant milk for smoked cheese production makes it possible to incorporate valuable nutrients into the diet, especially as the consumption of unprocessed sheep or goat’s milk is low compared to that from cows. Smoking of food not only prolongs its shelf-life but also improves its flavour. Taking the fact that many consumers do not accept some organoleptic properties of milk from small ruminants into account, the aim of the study was to assess and compare the organoleptic and nutritional properties of traditionally smoked cheeses made from goat, sheep and cow’s milk. The analysed cheeses differed in terms of dry matter content and its components such as protein and fat. Their acidity was comparable, except for the sample made of raw goat’s milk, which was characterised by a relatively high pH value (6.12 ± 0.06). The highest content of CLA (2.30 ± 0.04%), as well as the highest share of unsaturated and polyunsaturated fatty acids, was determined in the cheese made from sheep’s milk. Moreover, the content of butyric and caproic free fatty acids in cheeses made from goat’s milk was found to be several times higher than in the other analysed cheeses. The organoleptic assessment did not reveal any significant differences between the cheeses produced at small, private farms and in industrial conditions, or between different types of cheese, regardless of the type of milk from which they were produced.

Abstract The benefits of human consumption of goat's milk are given by the presence in this milk of short-chain fatty acids (approximately 20% are short-chain fatty acids) and medium-chain fatty acids (55%), this milk being easier to digest. An important qualitative indicator of goat's milk with technological, nutritional and dietary impact is the fat content. Our data show that the percentage of milk fat increases immediately after parturition, then decreases for most of the lactation. This is due to two factors: a diluting effect, by increasing the volume of milk to the maximum level of lactation and a decreasing effect of lipid mobilization, which leads to a decrease in the plasma level of unesterified fatty acids (especially C18:0 and C18:1), with a role in lipid synthesis in the mammary gland. From the third month of lactation, the average daily amount of milking milk undergoes only slight variations. Also, the fat and protein percentage remain relatively constant during June-August. In summer there was an increase in the levels of monounsaturated, polyunsaturated fatty acids and of conjugated linoleic acids in milk, compared to spring. Our results indicate that multiparous Carpathian breed females, whose food comes mostly from grazing, produce milk during the summer with a ratio between omega-6 and omega-3 below 4.
