This paper presents the results of complex radioecological monitoring of the territories, which are situated near the Semipalatinsk Nuclear Test Site, East Kazakhstan region. The radiometric measurements showed that the concentration of radon and beta particles are below the permissible levels. EROA values of a radon in rooms fluctuates from 44 Bq/m3 to 195 Bq/ m3. The measured values of fluency of betta-particles in all the studied points are less than 10 freq/ min*cm2. A specific activity of radionuclides, such as Am-241, Cs-137 and Pu – 239/240 in soils, plant, water, meat and milk were evaluated.
Semi-smoked sausages were made with 5%, 10%, 15%, 20%, and 25% replacement of horsemeat by emulsion gel made with offal broth (stomach, kidney, liver, heart, brain, and a miscellaneous trimmings of a horse), pumpkin flour, and egg yolk in a ratio of 5:4:1. The technological, nutritional, oxidative, and rheological (G′ and G″) properties were studied. Sausage water holding capacity (WHC) rose after being incorporated with pumpkin-based emulsion gel (PEG). There was a statistically significant (p < 0.01) improvement in sausage emulsion stability. Lipid oxidation in all samples, especially 5% and 15% addition of emulsion gel samples, was below the rancidity criterion, which is TBARS > 2.0–2.5 mg MDA/kg sample. This really is encouraging because unsaturated fatty acids, such as those found in horsemeat, are easily oxidized. Use of the emulsion gel did not noticeably alter the sausages’ pH. Using emulsion gel considerably reduced the cooking loss (p < 0.05) of sausages and significantly improved texture (p < 0.05). Partial replacement of mixed horsemeat with emulsion gel improved the physicochemical characteristics of semi-smoked sausages. The elasticity modulus (G′) showed that PEG15 (15% of emulsion gel) was the most resilient gel. The least powerful gels (p < 0.05) were PEG20 and PEG25. According to this study, adding a pumpkin-based emulsion gel to the meat matrix could improve the quality of the emulsified meat system and provide important data for related research and companies as strategies to market a healthier and more nutritious product with the necessary quality characteristics.
The consumer preference for ready-to-eat foods is growing rapidly, it provides many benefits to health care because it is very rich source of dietary fiber, minerals, and amino acids. The present study was to prepare and evaluate the quality of turkey meat pâté made with a high nutritional value protein-herbal supplement containing cereal flours (oat, rice, corn, and buckwheat). The physicochemical characteristics (pH, aw, color, texture, chemical composition), amino acid profile, sensory and quality analysis for turkey meat pâté were investigated. The use of the protein-herbal supplement decreased lightness (L*) and redness (a*) values but intensified the yellowness (b*) of cooked pâtés. The amount of essential amino acids significantly increased compared to the control sample. The protein-herbal supplement which was developed was proved to be very rich source of unsaturated fatty acids: the content of monounsaturated fatty acids increased by 27.8% and polyunsaturated acids by 0.7% in the final pâté.
The article presents the results of the study of the nutritional value of meat cutlets from veal with the addition of cedar nut cake. The chemical and mineral composition of the cake obtained from the seeds of Siberian cedar growing on the territory of Eastern Kazakhstan has been determined. Four variants of cutlets with the addition of 0, 5, 10, and 15% of cedar cake are developed. The results of the analysis show that increasing the amount of cedar oil cake in the composition of meat semi-finished products increases the protein content (P<0.01) but at the same time the fat content in the experimental samples decreases (P<0.01) due to lower fat content in the veal meat. In terms of fatty-acid composition, the cutlets are characterized by high PUFA content (48.08%), followed by MUFA (29.46%) and SFA (22.46%). The developed cutlets are enriched with magnesium (100.4 mg/100 g) and calcium (75.3 mg/100 g), and iron content is 2.78 mg/100 g. The analysis of microstructure showed that cedar nut cake is evenly distributed among the muscle fibers in minced meat. The inclusion of cedar nut cake in the recipe for veal cutlets helps to improve the mineral, amino-acid, and fatty-acid composition and allows this product to be classified as a functional dietary product.
This study was specifically designed for a small-scale meat processing enterprise “DARIYA” to set up a specific HACCP plan for the new product (patties) made from mixed horsemeat with vegetable components developed in the Department of Technology of Food Production and Biotechnology, Shakarim University of Semey. Critical control points (CCPs) were identified and applied in the HACCP plan. The different hazards were detected at each processing step, whereas each CCP in the HACCP plan was identified and accompanied with the appropriate significant hazard, critical limit, monitoring of the CCP, and corrective actions, confirming that the enterprise has fully employed the HACCP methodology and ISO 22000:2018. Our results indicate that during almost 1 year following the implementation of ISO 22000:2018, the coliform level of tested patties significantly dropped (p < 0.05) after 6 months of implementation (coliform count dropped from 4.4 MPN/g to 1.8 MPN/g). The rapid screening of the bacterial count, heavy metals, pesticide residue, and physical contamination levels also improved monitoring assertiveness, allowing them to deal with foreseeable issues linking to resources and guarantee product quality. Cesium-137 was recorded as 5.4 ± 2.9627 Bq/kg in horsemeat and 6.7 ± 2.7045 in poultry. The activity of cesium-137 did not exceed the MAC. This result discloses that prompt screening is the foremost and necessary step for small enterprises. According to this study, the “acceptance of raw materials” is the most important CCP, and their control, particularly in small-scale meat processing enterprises, can actually prevent many negative outcomes. The implementation of both standards improved food quality by declining the flaw rates for patties, and the number of flow inconsistencies needed for correction in the process also dropped significantly (p < 0.05), demonstrating that safety and quality points were improving. If the application of the HACCP plan were to continue over an extended period of time, the Food Safety Management System's (FSMS) benefits would be more substantial improvements to a greater number of items being monitored. The process of implementing HACCP principles and ISO 22000:2018 could be arduous but achievable enough to be used in small industries with significant outcomes.
