Offal, such as liver, heart, tongue, kidneys, blood, skin, bone, etc., represents an essential source of protein, vitamin and mineral elements. The present study is an attempt at determining the amino acid composition of horse and beef liver and blood. In general, horse liver was to be a good source of protein (25.06%) compared with beef liver (17.4%). The moisture (74.9%) and fat (3.8) contents were significantly higher (p<0.05) in beef liver, while the ash content of the horse liver was 1.42% compared to 1.30% in beef liver. Total essential amino acid content was higher in beef liver (40.63%) than in horse liver (37.31%).

Cesium-137 (Cs-137) activity concentration in cow milk samples, collected near the former Semipalatinsk nuclear test site (SNTS) in Kazakhstan were measured. Milk samples were obtained from 7 different locations within 2 administrative regions (Abai and Ayaguz). Abai and Ayaguz regions belong to different zones of radiation risk: zone of maximum radiation risk and zone of heightened radiation risk, respectively. Radionuclide activities concentrations were determined using a gamma-ray spectrometer with pure germanium detector. The highest activity concentration values in milk were found in Karaul of Abai region 8.60±0.16 Bq/l. In Zhidebai, Kaskabulak, Kokbai and Medeu the Cs-137 activity concentration were 5.30±0.21 Bq/l, 4.10±0.12 Bq/l, 7.10±0.22 Bq/l and 3.70±0.14 Bq/l, respectively. In Ayaguz region the average value was 3.60 Bq/L. In this zone, the highest activity concentration was measured in Akshatau 6.60±0.27 Bq/l. In Ayaguz Cs-137 content was lower 2.60±0.09 Bq/l.

This study aimed to determine the effect of technological parameters of the production of horse meat minces with the addition of protein-oil emulsion from chicken combs on the functional, technological and physicochemical indicators. Chicken combs were pre-treated with bacterial concentrate to improve their properties. Experimental approach: The ultimate shear stress and technological indicators – water holding capacity and oil holding capacity – were determined to set the optimal time for cutting raw materials. Physicochemical analyses of the meat minces were conducted. Results and conclusions: The research results have shown that the cutting time significantly affects the meat minces' rheological, functional and technological indicators. The optimum mixing time for meat minces is 6 min. Adding a protein-oil emulsion from biotechnologically processed chicken combs, cottonseed oil, and water into the minced horse meat does not significantly affect the nutritional value. Adding 15 – 20% protein-oil emulsion (POE) is recommended to get minced meat with optimal rheological parameters. Novelty and scientific contribution: The research results allow the rational use of poultry by-products.

Medicinal plants are one of the main sources of vitamins, minerals salts, macro-and microelements, and other biologically active substances that have a health and protective effect on the human body. The current study was aimed to appraise the heavy metals contents in the powder materials of two medicinally important plants Echinacea purpurea (L.)  and Rhapónticum carthamoídes collected from the Semipalatinsk nuclear test site using atomic absorption spectrophotometer. Flavonoids, saponins, amino acid contents quantification were done both in raw materials as well as tincture prepared from both plants via GCMS-QP 2010 Ultra chromatomass spectrometer. Further, tannins concentrations and organoleptic properties of the tincture were elucidated using previously reported standard procedures. In the current study, the concentrations of heavy metals were within the permitted range i.e. lead (0.0027 mg.100g-1), cadmium (0.00012 mg.100g-1), arsenic (ND), mercury (ND). In the crude powder, flavonoids were observed to be in the highest concentration in E. purpurea (L.) (5.5 ±0.20 mg.100g-1), whereas, its concentration was 3.1 ±0.346 mg.100g-1 in R. carthamoídes powder. Tannin concentration was higher in R. carthamoídes (5.5 ±0.115 mg.100g-1) and 3.1 ±0.46 mg.100g-1 in E. purpurea. Likewise, saponins concentrations were 4.1 ±0.40 mg.100g-1 and 5.6 ±0.17 mg.100g-1 in E. purpurea and R. carthamoídes powder respectively. Concentrations of these active metabolites in the resultant tincture were flavonoids (7.6 ±0.23), tannins (7.5  ±0.28), and saponins (8.5 ±0.16) mg.100g-1. In the current study, we observed highest concentrations of these essential amino acids in the tincture including leucine/isoleucine (78.00 ±1.15 mg.100g-1), histidine (14.00 ±1.44 mg.100g-1), lysine (49.33 ±2.02 mg.100g-1), methionine (18.66 ±2.90 mg.100g-1), cystine (29.00 ±0.57 mg.100g-1), phenylalanine (24.16 ±1.87 mg.100g-1) and threonine (32.50 ±1.22 mg.100g-1) respectively. The resultant tincture has a pleasant agreeable taste coupled with acceptable herbal flavor which are important organoleptic properties for any product.
