Porcine Hemoglobin

Bovine (meat and heart) and porcine (hemoglobin and plasma) raw materials were hydrolyzed by Protease A (both endo- and exopeptidase activity), with or without glucosamine added during the enzyme inactivation step. Hydrolysates were characterized via peptide analysis (yield, UV- and fluorescence scanning spectroscopy, and peptide size distribution via size exclusion chromatography), sensory evaluation, and volatile compound analysis via gas chromatography mass-spectrometry (GC-MS) to determine if glucosamine-induced Maillard reaction improved taste and flavor. Porcine hemoglobin produced the most flavor-neutral hydrolysate, and could expectedly have the broadest application in food products. Both bovine meat and -heart hydrolysates were high in umami, and thereby good candidates for savory applications. Porcine plasma hydrolysate was high in liver flavor and would be suitable for addition to certain meat products where liver flavor is desirable. All hydrolysates had low perceived bitterness. Glucosamine-induced Maillard reaction had just a minor influence on the sensory profile via an increased perception of sweet taste (p = 0.038), umami taste (p = 0.042), and yolk flavor (p = 0.038) in the hydrolysates, irrespective of raw material. Glucosamine addition had a statistically significant effect on 13 of 69 volatiles detected in the hydrolysates, but the effect was minor and raw material-specific.

Fresh juices from mandarin varieties, from hybrids, and from blends of these raw materials were evaluated by 100 consumers to determine acceptability, and by 10 trained panelists to quantify sensory attributes. Trained panelists found the juice from Clemenules richer in both mandarin and fresh flavor (odor and taste) whereas Nova juice presented minimum scores for these attributes. These aspects obviously affected the evaluation of acceptability by consumers, who preferred the juice from Clemenules (a Clementine variety) either alone or blended in major proportions with less preferred varieties such as Marisol, Hernandina (Clementines), Ortanique or Nova (hybrids). Nova juice was rejected by most consumers, but accepted by a small group of them. These results are of great importance for the European citrus industry since Clemenules is the most abundant variety and will constitute the main source of raw material for processing plants.

Creation of combined meat products combining traditional consumer properties, as well as the possibility of using non-traditional raw materials in their recipes, is aimed at the expansion and rational use of the raw material base of the meat processing complex and solves the problem of reducing nutrient deficiency in the diet of the population. Therefore, the issue of the use of mechanically deboned poultry meat in meat bread technology and its impact on qualitative indicators and functional and technological properties is relevant. The aim of the research was to study the feasibility of the use of mechanically deboned poultry meat in the technology of combined products. Three model recipes based on the formula-meat analogue “Chainyyi” were developed. The possibility of replacing beef and pork meat with duck meat and mechanically deboned poultry meat of turkey was studied in the bread recipes. The total amount of duck meat and mechanically deboned poultry meat was 63%. As a protein ingredient able to bind moisture and relatively inexpensive compared to meat raw material, 20% of the pig's heart was added to the formulation, as well as 2% XB Fiber. Other components of the analogue formulation have not changed. Combination of duck meat with mechanically deboned poultry meat of turkey and pork hearts in the abovementioned ratios as part of meatcontaining bread stuffing systems allowed to improve the nutritional value of the product and its qualitative indices. The research confirmed the possibility of combining regional and relatively cheap raw materials to increase the nutritional value of meatcontaining products, namely breads. The bulk of proteins in the experimental samples increased by 6.57–10.38% and was within the range of 17.96–17.34%. On average, 4.98% decreased the fat content, the product became less calorie relative to the analogue by 15.98–16.76%. The formulations of model minced meat were distinguished by a higher index of the water-holding capacity, the content of binding moisture and the best indicators of plasticity. This affected the quantity of finished products, which amounted to 120.64–117.3% to the mass of raw materials, while in the control sample this figure was lower by 3.49–7.47%.

The article is devoted to the improvement of the recipes of minced meat products with using fish raw materials and the study of organoleptic and functional and technological properties of developed minced meat systems and finished products. The research has been carried out on the rational combining of meat and fish raw materials and the expansion of assortment of minced semi-finished products. The formulations of minced meat systems for the production of meat semi-finished with a partial replacement of the main raw material to fish raw materials have been developed. The organoleptic and functional and technological parameters of minced meat systems and finished products are investigated. According to the results of the organoleptic evaluation, it was found that partial replacement of meat raw material with minced fish does not worsen the sensory characteristics of minced meat products. It is established that in comparison with the control sample there is an improvement of functional and technological indicators. In particular, the moisture content increased by an average of 6.1%, moisture absorption capacity – 5.91%, energy absorption capacity – 2.49%, fat-retaining ability – 2.52%. The obtained results confirmed the expediency of using minced meat with pollack in the technology of minced meat semi-finished products with due observance of the parameters of production cycle of heat treatment of products. It has been theoretically substantiated and experimentally confirmed the technology of meat products using minced meat and developed recipes. It has been established that with careful selection of components that are part of minced meat semi-finished products with the addition of fish raw materials can increase the organoleptic and functional and technological parameters of finished products. The obtained data suggest that the improved recipes of minced meat semi-finished products can be recommended for production by enterprises of the meat industry and restaurants

Dairy Processing

Consumption of dairy and meat products rich in valuable and essential nutrients holds a special place in the diet of the population of all ages. Along with sufficient and balanced consumption of meat and dairy products the issue of their security and quality is no less important. There is a trend of reducing the production volumes of beef and veal, caused by the decrease in demand for this type of meat, which is more expensive than pork and poultry. Industrial enterprises, producing finished meat products on the basis of cattle meat, should choose one of two strategies of resource provision: creation of the own raw material zone due to the local producers and transport links or formation of long-term import contracts. The production of pork and poultry is growing. Production of sausages and similar products from meat is reducing, which is caused by the fact that a part of households refuses to consume finished meat products with added preservation agents, coloring agents, color stabilizers, flavor intensifiers, soy, protein, etc. Taking this into account, national producers of finished meat products should review the approaches to security and quality of their produce. Otherwise, their main threats will be a further reduction of supply and loss of a market niche. An acute problem of the national dairy processing industry is the growing deficit of milk raw material. The main reason for insufficient production volumes of milk by agricultural producers is a low purchasing price offered them by national dairy processing enterprises. Therefore, it is necessary to stimulate domestic demand for the finished dairy products in order to revitalize investment activity of milk processing enterprises and to increase purchasing prices of milk raw products, in the first place, at the cost of special social care programs for low-income people. Key words: dairy-and-meat industry, beef and veal, pork, poultry meat, sausages and similar products from meat, gastronomic culture, milk raw materials, deficit, dairy products, milk products, SCSU, purchase prices, food aid.

Abstract As one of the three main components in woody biomass, lignin is an abundant but underused renewable raw material and carbon source. Owing to its aromatic structure and large availability as a by-product of pulping, its conversion into chemicals is highly attractive. In the present work, the oxidation of a softwood kraft lignin in acidic media was investigated in the presence of a homogeneous catalyst. The objective was to find a cheap but efficient catalyst for the depolymerization of kraft lignin into aromatic monomers. Different transition metal salts were screened and compared to phosphomolybdic acid, which was investigated in previous studies, and to experiments in sulfuric acid without additional catalyst. Vanillin and methyl vanillate were the main monomeric products detected by gas chromatography/mass spectrometry but their formation was only slightly increased by using transition metal salts (up to 6.28 wt% yield). However, the presence of iron or copper chloride resulted in fast formation kinetics and significant amounts of other monomeric products. In addition, an efficient fragmentation of the lignin molecule from a weight-average molecular weight of 3500 g mol-1 down to 500 g mol-1 was observed by size-exclusion chromatography. The enhanced incorporation of oxygen into the reaction products in the presence of those catalysts was proven by Fourier transform infrared spectroscopy and the influence of the catalyst concentration was studied.

This paper presents the results of an experimental study of the component composition of essential oil samples obtained from various vegetable raw materials of Schisandra chinensis (Schisandra chinensis (Turcz.) Baill.): branches (woody stems), rhizomes with roots and leaves. The extraction of essential oils was carried out by distillation with water vapor followed by extraction from the distillate with ethoxyethane. The largest yield of essential oil in terms of completely dry raw material is registered from rhizomes with roots – 0.99%; the yield from leaves and branches was approximately the same: 0.51% and 0.52%, respectively. A comparative analysis of the component composition of the obtained essential oils was carried out using the gas chromatography / mass spectrometry method. In the essential oil of the leaves 29 detected compounds (identified by 21 connection; dominant components: Cyclohexylmethyl ether sulphurous acid, (+)-trans-nerolidol, δ-cadinene, Tridec-(2E)-EN-1-ol), woody stems 80 connections (identified 65 compounds; dominant components: ß-pinene, Camphene, Bornylacetate, (+)-trans-nerolidol, p-tsimen, Tridecan-2-it, δ-cadinene), rhizomes with roots 78 of the compounds (60 compounds identified; dominant components: δ-cadinene, Bornylacetate, β-pinene, Camphene, Nerolidol-(E), Tridecan-2-it, γ-cadinene, Borneol). For each sample of the studied essential oils selectivity and marker substances were established.

This study considers the development of combined meat products containing, along with meat raw materials, other types of raw materials of animal and vegetable origin. The aim of the research is to substantiate the advantages of combining duck meat of regional origin with other types of raw materials in meat-containing cooked smoked sausages. A model for studying of the feasibility of combining duck meat of regional origin with other raw materials was a recipe for cooked smoked sausage containing meat of the Muscovy duck and also including pork hearts, salted pork side-fat, soybean isolates, pork skin protein, edible albumin “Aprored.” In the model samples of forcemeat for meat-containing cooked smoked sausages, functional and technological properties have been determined according to standard methods. The biological food value of the finished products has been determined as well. The analysis of the results confirms that the combination of Muscovy duck meat and protein-containing secondary raw materials improves the moisture content, water-holding capacity, emulsifying ability, and stability of the emulsion. The study of the microbiological parameters of the sausages developed has indicated that the number of mesophilic aerobic and facultative anaerobic microorganisms (MAFAM) in all the samples studied was within the normal limits. The study of the number of bacteria of the E. coli group has not detected these microorganisms in any of the samples. For the ω-6 and ω-3 family, its high biological value as for the content of essential amino acids and its biological effectiveness as for the fatty acids have been confirmed. It has been proved that duck meat can be combined with traditional types of meat and vegetable raw materials to increase the biological effectiveness of meat-containing cooked smoked sausages. It has been determined that when Muscovy duck meat is combined with non-meat kinds of protein-containing raw material (pork skin protein, soybean isolate) as part of meat-containing cooked smoked sausage, it allows producing nutritious food with high quality characteristics.
