Rice is one of the most important food crops in the world. Its biggest flaw is the low content of protein and essential amino acids, which severely limits its nutritional value. In order to produce high-quality rice with rich Se, we sprayed different concentrations of compound nutrient solution (containing Se (selenium), amino acid compound, zinc and boron) on the rice at different growth stages; and then determined the main nutrient content of their polished rice. The results showed that spraying low concentration compound nutrient solution (Each liter contained 20 mg of Se, 333 mg of complex amino acids, 33 mg of zinc and 33 mg of boron) to rice in the heading stage produced rice with the highest total starch and fat content and lower amylose content. Spraying high concentration compound nutrient solution to rice during the filling stage produced rice with the highest Se content. Multiple sprays of compound nutrient solution produced rice with low protein and low starch. Spraying low concentration compound nutrient solution on rice in milky stage significantly increased the content of protein, total starch, fat, all essential amino acids (Lysine increased by more than 57%), amylopectin and Se in rice; significantly reduced amylose content; significantly improved the nutritional value and taste quality of rice. The conclusion is that spraying low concentration compound nutrient solution on rice in the milky stage can produce rice with the highest content of protein and essential amino acids, higher content of total starch, fat and Se, and the lowest amylose content; significantly improve the nutritional value and taste quality of rice. The technical solution can comprehensively and effectively improve the nutritional value and flavor quality of rice, and has great development and application value.

Relevance. The article provides a justification for the use of sheep selection taking into account the intra-breed type of Prekos ewes in purebred breeding and crossing with producers of semi-fine wool breeds Romney-Marsh and Kuibyshevskaya to improve the biological usefulness of meat in offspring.Methods: scientific and economic experiment in the use of different selection options, taking into account the productive type of sheep of the Precos breed.Results. The article presents the results of a study on the influence of the selection of sheep on the composition of lambmeat, increasing the usefulness and quality of meat and, thus, the efficiency of its production. It was found that the content of water in the meat of crossbred animalswas lower compared to purebred Precos. There is a lower water content in the meat of rams obtained from sheep of the Precos meat-wool type, both in purebred and crossbred animals. In terms of the protein content in meat, there is an advantage in rams with purebred breeding and crossing compared to meat obtained from the wool-meat type of queens. In the hip bran of purebred animals and crossbreeds with the Kuibyshev breed, this superiority was 1.1% (Р > 0.95), and in the lumbar bran of Romney-Marsh crossbreeds, this difference was 1.6% (Р > 0.95). Mutton from the offspring of the sheep of meat-wool type is characterized by a significantly high content of the essential amino acids threanine, lysine, leucine, phenylanin and isoleucine in comparison with meat from the offspring of the wool-meat type of sheep. A significant superiority was also established in the content of interchangeable amino acids — oxyproline, serine, tyrosine, proline, glycine, aspartic and glutamic acid, cystine and analin.

Poultry Diets

The price-to-quality ratio of broiler chicken meat is one of the reasons why consumers use these products in their daily diet. The quality of poultry products such as meat is closely associated with the nutritional value and quality of feed fed to broilers. In composing broiler diets, the main focus is turned on crude protein (CP). Because of the trend for the poultry industry to reduce its dependence on soybean meal as a source of protein, the role of pulses in the supply of protein and energy, which could partly replace the soybean meal in poultry diets, increases. Due to considerable progress in plant breeding, the present research study used peas (Pisum sativum) of the var. ‘Bruno’ and var. ‘Pinochio’ as well as faba beans (Vicia faba minora) of the var. ‘Lielplatone’ was developed in Latvia. Higher protein diets induce a higher meat protein content, accordingly, feed proteins are hydrolyzed in the digestive system into amino acids (AA) that, after absorption, are used to form proteins and to build different body tissues. The most important AA was twofold lower in peas and faba beans than in soybean meal. Although the amount of AA in feed is not directly proportional to the content of AA in broiler chicken meat, the amount of AA in poultry feed can significantly affect an important meat quality criterion for consumers – the nutritional value of protein. Therefore, the research aimed to identify changes in AA composition and chemical composition – a qualitative property of poultry meat – as a result of adding pulses (peas and beans) to poultry diets. The research results showed that the diets with an addition of faba beans and peas had a positive effect on the level of essential amino acids (EAA) and non-essential amino acids (NEAA) in broiler meat, decreased cholesterol concentration in meat, and increased energy value of meat.

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.

Effect of storage time on the quality of smoked heteroclarias was studied. 108 samples of heteroclarias (average weight 210 + 15g) was used. Analysis carried out include: proximate, mineral composition (Ca, Na, Fe and Mg), biochemical, amino acid and sensory evaluation. Data obtained was subjected to Analysis of Variance (ANOVA) while the sensory data was subjected to nonparametric test (Kruskal Wallis test). Smoked heteroclarias have good nutritional quality in terms of proximate, mineral and amino acids all of which decrease with increase in duration of storage at ambient temperatures. Glutamic acid  was the most predominant amino acid and the highest non-essential amino acid (NEEA), lysine was the most predominant EAA. There was higher concentration of non-essential amino acids than essential amino acids, EAA/NEAA ratio (0.86 – 0.93) recorded indicates that the fish have excellent protein quality; its the predicted protein efficiency ratio (P-PER) ranged between 3.44-3.61 and its biological value ranged between 79.84 -75.04. Its chemical score and TEAA decrease with increase in storage time. Its texture quality reduced significantly (χ2 = 12.207, p<0.01) with increased storage period. It is therefore recommended that smoked heteroclarias be consumed as soon as it is smoked and regularly for good healthy conditions especially among children, aged and other vulnerable groups.

Soft rice is a kind of high-quality rice between glutinous rice and sticky rice. It has low amylose content, crystal clear grains, sweet taste, soft glutinous, and is suitable for cooking and porridge. Chalkiness in soft rice is a white opaque part formed by loose endosperm. It is an important character that affects the appearance quality, processing, and cooking quality of rice, and also an important limiting factor that restricts the standard rate of high-quality rice in China. The combination of scanning electron microscope and energy dispersive spectrometer (SEM-EDS) can be used for in-depth analysis of rice, visualization, and quantitative analysis of element distribution in rice. The results showed that there were many kinds of mineral elements in soft rice seeds, among which C and O were the most abundant, followed by N and P, and Mg, Al, P, S, K, Ca, Mn, and Zn were less. The contents of C, N, P, and S in the non-chalky area were significantly higher than those in the chalky area. Especially N and S were the best indicators of protein, and the contents in the chalky area were higher than those in the non-chalky area. It means that the protein content in the chalky part of soft rice seed is less than that in the non-chalky part, which affects the nutritional quality of soft rice. Therefore, the results of this study laid a solid foundation for the in-depth analysis of the distribution of mineral elements and protein in soft rice and their effects on the quality of soft rice, which also provided important information for the cultivation of new high-quality rice varieties in the future.

The effect on the protein quality of meat meals of processing them under commercial conditions in a continuous dry renderer at maximum temperatures ranging from 116 to 160°C for a running time of 115 min was studied. Although the total levels of amino acids were little affected by processing temperatures, the biological availability of all essential amino acids, as determined by the protozoan Tetrahymena pyriformis, was reduced as the processing temperature increased. At 140 and 160°C the availability of certain amino acids was reduced by 37-56%, lysine, histidine, and methionine being the most severely affected. The availability of essential amino acids in meals produced at temperatures from 121 to c. 138° was not significantly different. The growth-promoting ability of the meat meals for chickens was closely related to the availability of the essential amino acids. __________________ *Part VI, Aust. J. Agric. Res., 19: 171 (1968).
