Application of whey protein hydrolysate as a technological additive in the sour cream production
In the context of economic sanctions, the problem of supplying food additives, including stabilizers and thickeners, which are important in the production of fermented milk products, remains relevant for many enterprises; the development of a fermented milk product – sour cream, using whey protein hydrolysate as a technological additive is relevant. The purpose of the research was to study the effect of whey protein hydrolysate on the technological process of manufacturing a fermented milk product, sour cream, and the quality indicators of the final product. The results of the acidity study showed that in the experimental samples, the ripening process occurred faster than in the control sample. Based on the results of the research, it can be concluded that whey protein hydrolysate can be used as a technological additive in the production of fermented milk products to improve quality indicators
The effect of protein hydrolysate on the functional and technological indicators of pate
It is advisable to study the effect of new protein additives on the functional and technological properties of food systems, taking into account a wide range of food and technological additives used in the production of meat products. The purpose of the research is to determine the effect of protein hydrolysate on the functional and technological indicators of pate. Optipep protein hydrolysate was used. Research methods. The functional and technological indicators of the protein hydrolysate were determined; the physico-chemical indicators of the pate samples were determined, and the obtained values were compared with the requirements of the state standard. The yield of the product after heat treatment was also determined. Results. It has been established that protein hydrolysate has high functional and technological indicators, which affect the increase in the yield of the product, as well as the increase in moisture, which contributes to a more spreadable consistency of the product. Samples of pate with the introduction of protein hydrolysate have a higher nutritional value. Based on the results, concluded that it is advisable to use protein hydrolysate in the pate recipe to improve its quality indicators
Adaptive Adjustment in Taraxacum Officinale Wigg. in the Conditions of Overburden Dump
Morphological and anatomical features of the leaves and roots of Taraxacum officinale Wigg., growing under the conditions of the rocky dump of the Kedrovsky coal mine of the Kemerovo region, were studied. It was revealed that the specific environmental conditions of the dump cause morphological and anatomical changes in the leaves and roots of the dandelion. At the level of morphology, a decrease in the average leaf area, a thickening of leaf blades, a tendency to decrease the number of leaves in the rosette, a significant decrease in the mass and length of the roots. At the level of the anatomical structure of the leaves, there is a significant increase in the thickness of the mesophyll, a tendency to decrease the thickness of the tissues of the upper and lower epidermis, a decrease in the number of cells in 1 mm2 and an increase in the size of stomata in the tissues of the lower and upper epidermis, a decrease in the number of stomata by 1 mm2 and a stomatal index on the upper epidermis. At the level of the anatomical structure of the roots, the radius of the root decreases, the radius of the cortex and phloem, the diameter of the xylem
The influence of soil microorganisms on heavy metal content in the substrate of waste rock dumps
The environmental effects of mining and its impact on natural resources are of a holistic nature. One of the modern methods employed for the remediation of technogenically disturbed soils is the application of microorganisms. This paper studies the impact made by soil microorganisms on the accumulation rate of heavy metals in the substrate of waste rock dumps in the process of soil reclamation. Suspensions of soil microorganisms (microorganisms utilising mineral nitrogen forms / MUMN; microorganisms decomposing silicates / MDS; microscopic fungi / MF) were applied to the rock dump surface. Separate groups as well as their combinations were applied. The heavy metal content analysis did not indicate a significant exceedance of the maximum allowable concentration limits (MACL) in the soil of the waste rock. The only metal whose content exceeded the maximum admissible concentration limits was nickel. It has found that the application of microorganisms influences the concentration of several heavy metals due to pH level changes of the rock dump soil
Ecosystem of Medicinal Plants Species and Potential of Growing on the Dumps of Kedrovsky Surface Mine (Kemerovo Region)
The medicinal flora of phytocenosis “Yuzhny” waste dump Kedrovsky coal mine pit in Kemerovo region was studied. It has been established that 51 species of medicinal plants belonging to 46 genus and 27 families grow on the waste dump. They are permitted for use in official medicine and included in the Medicines State Register in the territory of the Russian Federation. The most of medicinal plants species are represented by forest (39.22%), ruderal (27.45%) and meadow (23.53%) vegetation, which in general is 90.2% of the identified medicinal plants number. The share of semi-aquatic and steppe vegetation accounts for 7.84% and 1.96%, respectively. It has been established that perennial herbaceous plants (25 species) predominate in the life forms composition; shrubs and trees account for 7 and 9 species, respectively. Researches were established a group of medicinal plants with resource potential and interest in raw materials procurement. This group include 13 herbaceous plants (Achillea millefolium L., Viola arvensis Murr., Polygonum aviculare L., Melilotus officinalis (L.) Pall., Fragaria vesca L., Verbascum thapsus L., Urtica dioica L., Filipendula ulmaria (L.) Maxim., Tussilago farfara L., Taraxacum officinale Web., Tanacetum vulgare L., Plantago major L., Artemisia absinthium L.), 5 shurbs (Crataеgus sanguĂnea Pall., HippophaĂ« rhamnoides L., Rosa accicularis Lindl., Rosa majalis Herm., Viburnum opulus L.) and 5 trees ( Betula pendula Roth., Betula pubesccens Ehrh., Padus avium Mill., Sorbus sibirica Hedl., Pinus sylbestris L.)
The Research of Low-Molecular Protectors in Taraxacum Officinale Wigg. in Connection with Mining Waste Utilization
This paper presents a research on the content of low-molecular metabolites possessing protecting properties (free proline, reducing sugars, succinic acid) in Taraxacum officinale Wigg. which grows on the mining wastes of Kedrovsky open pit in Kemerovo region. The paper also researches the topic of relation between the content of the above substances and morphometric characteristics of the plant such as weight of leaves and roots, length of roots and surface area of leaves. In the course of the research in was established that adverse edaphic effects of mining waste cause adaptive changes of Taraxacum, which affect the plant on biochemical and organ level. As for biochemical level the increase in content of low-molecular protectors in leaves and roots was revealed. As for organ level the evident reduction of morphometric characteristics (weight of leaves and roots, length of root, surface area of leaf) was revealed which can be interpreted as an evidence of xerophytesation increasing the plant’s survivability in hostile environment. The revealed adaptive changes described above form the plant’s resistance to the extreme environmental factors and present an evidence of plant’s ability to fully conduct its vital functions in the conditions of the mining waste
