Goat Meat

Today, goats are spread throughout the world. They live in small or large herds and in different areas and environments. Because of its distinctive taste and desired chemical composition, goat meat is increasingly consumed in Serbia. As animal foods, it is rich in protein, vitamins and minerals, but contains very little fat, especially cholesterol. The aim of this review paper is to highlight some health benefits, nutritional values and potential use of goat meat. On the chemical composition of goat meat affect race, gender, productivity and adaptability to stress, environment, management, diet, weight at slaughter and health condition as well as slaughter and procedures with the carcasses after slaughter. Average chemical composition of lean goat meat contains about 75.42% water, 3.55% fat, 19.95 % protein and 1.06% mineral matter. The energy value is about 580 kJ per 100 g. The goat meat has about the same nutritional value as well as sheep meat. Due to low content of saturated fatty acids and cholesterol, goat meat in the human diet is healthier alternative compared to other types of red meat. Polyunsaturated fatty acids prevalent in goatmeat, and the diet rich in unsaturated fatty acids is correlated with a reduced risk of stroke and coronary disease. In addition, in goat meat are present the essential amino acids such as lysine, threonine and tryptophan. Regardless to the nutritional value, goat meat is still less appreciated due to their specific smell and taste, the more if the animal is older.

Despite being highly appreciated and consumed, the nutritional value of Chaceon maritae from Namibe (Angola) had never been studied. In the present work, edible tissues (muscle, ovaries, and hepatopancreas) of boiled female C. maritae caught off Namibe coast in two distinct seasons were analyzed in terms of proximate chemical composition (fat, ash, protein, and moisture), fatty acid and amino acid profiles, cholesterol, essential minerals (macro and trace) and toxic elements. Results showed that, in both seasons, C. maritae muscle was a valuable source of protein, essential amino acids, polyunsaturated fatty acids, and essential elements, especially zinc, selenium, iodine, and copper. Ovaries and hepatopancreas are also good sources of protein, but were richer in fat, particularly when caught in October. Ovarian fat is rich in polyunsaturated fatty acids and that of hepatopancreas has higher values of monounsaturated and saturated fatty acids. Hepatopancreas and ovaries are also good sources of copper and, especially ovaries, of zinc. Moreover, in both seasons, all the edible tissues of C. maritae analyzed presented very low contents of heavy metals (mercury, cadmium, lead, and arsenic).

Pig Carcasses

The chemical composition of pig backfat determines its physical properties of firmness and cohesiveness as well as its nutritional value. The firmness of the tissue depends upon its content of saturated fatty acids, particularly stearic, which make it harder; and unsaturated fatty acids, particularly linoleic, which make it softer. Cohesiveness depends upon the connective tissue and fat content and the compositon of these; soft fat and low cohesiveness frequently being found together. Nutritional value may be judged by the energy content of the tissue, which increases in proportion to its lipid content, or by the ratio of polyunsaturated fatty acids to saturated fatty acids (P:S ratio), used by COMA to indicate the desirability of the fat as a risk factor for cardiovascular disease. There is evidence that as fatness has been reduced in British pigs, composition has changed with consequences for these characteristics.

The aim of the study was to present a comprehensive characterisation of crayfish meat, which is crucial to assess its potential usefulness in the food industry. To this end, we assessed the yield, basic chemical composition (protein, fat, minerals), nutritional value (amino acid and fatty acid profiles, essential amino acid index (EAAI), chemical score of essential amino acids (CS), hypocholesterolaemic/hypercholesterolaemic ratio (h/H), atherogenicity (AI) and thrombogenicity (TI) indices), as well as culinary value (lab colour, texture, sensory characteristics, structure) of the meat of spiny-cheek crayfish (Faxonius limosus) (n = 226) from Lake Sominko (Poland) harvested in May–September 2017. Crayfish meat, especially that from the abdomen, was shown to have high nutritional parameters. It is lean (0.26% of fat), with a favourable fatty acid profile and a very high quality of fat (PUFA (sum of polyunsaturated fatty acids):SFA (sum of saturated fatty acids), n-6/n-3, h/H, AI, TI) and protein (high CS and EAAI). It is also a better source of Ca, K, Mg, Na, P, and Cu than meat from slaughter animals. Hence, crayfish meat can be an alternative to livestock meat in the human diet. Owing to its culinary value (delicateness, weak game flavour, and odour), it meets the requirements of the most demanding consumers, i.e., children and older people.

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.

Fat Fraction

On the basis of the high fat content of nuts, they are traditionally considered as foods that provide a high amount of energy. However, epidemiologic and clinical observations do not indicate an association between nut intake and increased BMI. There is a notorious variability in macronutrient composition among nuts, although they have some consistent patterns. Nuts contain all major macronutrients: protein, carbohydrate, and fat. The total protein content is relatively high, which makes them a good source of plant protein (especially for vegetarians). Although nuts contain low amounts of some essential amino acids, this is not a nutritional concern due to the complement of protein. In addition, nuts have a low lysine:arginine ratio, which is inversely associated with the risk of developing hypercholesterolemia and atherosclerosis. Carbohydrates are the second highest macronutrient in nuts in terms of total calories provided. The fat fraction is characterized by a high amount of unsaturated fatty acids and a low content of saturated fatty acids. In conclusion, the high content in unsaturated fatty acids, the low lysine:arginine ratio, and the presence of other bioactive molecules (such as fibre, phytosterols, vitamin and other antioxidants, and minerals) make the addition of nuts to healthy diets a useful tool for the prevention of cardiovascular heart diseases.

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.

The Impact

This paper analyzes the role of meat in human nutrition. Meat and meat products have been one of the main foodstuffs in human nutrition worldwide for centuries. Type and quantity of consumed meat were influenced by different factors (religion, social status, and offer) in the past. Meat and meat products are the foodstuffs, which are the most important for its composition and nutritive value. People who consume meat are provided with proteins which have balanced ratio of essential amino acids, B complex vitamins, micro elements (iron, zinc, copper) and energy. On the other hand, meat contains significant quantity of fats in which dominate saturated fatty acids and cholesterol. During technological process table salt is added to meat, thereby high concentrations of sodium enter the body.Researches in the last 30 years pay more and more attention to the impact that certain type of meats in human nutrition have on heart diseases and cardiovascular diseases, appearance of high blood pressure, stroke and colon cancer and to possibility if processing procedure would be changed, fats content, cholesterol and sodium would decrease, thus lowering the risk of mentioned diseases. The aim of this paper is to review existing literature for both the risks and benefits of meat consumption, focusing on case-control and prospective studies. Researches in the science of meat and meat technology gave results and meat products are obtained with lower sodium content, lower content of saturated fatty acids and higher content of poly-unsaturated fatty acids. Thus, meat and meat products will stay the most important foodstuffs in future centuries due to its nutritive, culinary and sensory traits.

In this article the chemical composition of 2 types of animal fats (cow milk fat and poultry fat) following the variation of saturated and unsaturated fatty acids proportion during freezing storage was studied. Determination of chemical composition of animal fats is important in establishing organoleptic and physico-chemical parameters, the variation of them in time, nature and proportion of fatty acids conferring specific characteristics to them. For milk fat was determined the following chemical composition: saturated fatty acids 68.35%, monounsaturated fatty acids 29.25%, polyunsaturated fatty acids 2.4%. After 4 months of storage under freezing there was a change in fatty acids proportion, saturated fatty acid content increased to 70.41%, monounsaturated fatty acids content decreased to 28.23%, and polyunsaturated fatty acids content decreased to 1.35% due to oxidation process when decreased the degree of unsaturation due to unsaturated fatty acids oxidation. In the case of poultry fat there was also an increase of saturated fatty acids (30.71%) and a decrease for monounsaturated (43.47%) and polyunsaturated (24.81%) fatty acids content.

Amaranthus Hypochondriacus

Amaranth is one of the oldest arable crop in the world. It was brought to Europe around the 17th century, but as an ornamental plant. It was not until the 1970s, after thorough examination of the chemical composition of amaranth seeds, that in effect of which the nutritional value of this plant was rediscovered and recognized. Since then, there has been increased interest in amaranth as a ‘plant with a future’. A great deal of scientific research has been carried out, leading to recognition of its nutritional, ecological, agricultural and health-promoting values (especially for the prevention and treatment of diseases of the cardiovascular, nervous and digestive systems). Among cultivated amaranths species Amaranthus caudatus, Amaranthus cruentus and Amaranthus hypochondriacus have the highest nutritional value. However, differences in the nutrient content are also noticeable between these species. One of the attributes of this plant is the high content of highly digestible complete protein and the presence of all essential amino acids in the seeds. The seeds also contain large amounts of gluten-free starch with a small grain diameter, fibre, vitamins and minerals. Furthermore, they have a high fat content compared to cereal grains. Amaranth oil consists mainly of unsaturated fatty acids (oleic, linoleic and linolenic). Some of the unsaturated fatty acids, such as linolenic acid, are exogenous fatty acids, essential for the human body. Valuable components of the fatty acid fraction include squalene, tocopherols and tocotrienols. These compounds are particularly valuable due to their antioxidant properties.
