Reduced Salt

Consumers in Czech Republic have high income of salt from food, therefore, there are efforts to reduce its content in meat products. The subject of this work was to examine differences in sensory evaluation of sliced cooked salami (Gothajský salami), manufactured according to various recipes. This type of meat product is well known primarily to the older generation of consumers, so the aim was to find out the differences in the perception of various samples between generations. The monitoring factors were salt content (1.6% or 2.0%), presence of monosodium glutamate (PG = presence or AG = absence) and group of evaluators (YC = 18 – 26 years old or OC = more than 60 years old). Older sensory panellists (OC; against YC) significantly (p ˂0.05) evaluated all samples more positively, especially in the taste and odour descriptors. Samples with monosodium glutamate (PG1.6 and PG2.0) were rated in the taste significantly better (p ˂0.05), regardless of the age of the assessors (YC and OC). Samples with reduced salt, without glutamate (AG1.6) were significantly worst evaluated (p ˂0.05) by both the groups (YC and OC) than PG2.0 samples.

High sodium and fat contents are cause of concerns for industries and consumers of meat products. Direct reduction of NaCl and fat is a useful strategy to understand how these ingredients interfere with the quality parameters of an emulsified meat product and how to reduce them without significant changes from the original product. The aim of this work was to understand salt reduction in fat-reduced (10 g fat/100 g product) hot dog sausages. Five NaCl concentrations were tested: 1% (F1), 1.25% (F1.25), 1.50% (F1.50), 1.75% (F1.75) and 2% (F2 – control). Proximate composition, sodium content, water activity, pH, emulsion stability, color, texture, scanning electron microscopy results and sensory attributes (just-about-right and acceptance tests) were assessed. Emulsion stability decreased ( P < 0.05) with salt reduction. Salt reduction increased water activity. Microscopic images showed a more compact matrix with the decrease in salt content. Sausages with the minimum (F1) and maximum (F2) amounts of salt were less accepted by consumers. A reduction of 26.8% of sodium can be obtained (with the formulation F1.25), allowing the labeling of sodium-reduced sausage and with acceptance by consumers.

Fat Reduction

The aim of this study was to analyse the occurrence and specific composition of meat products (MPs) bearing nutrition/health claims marketed in the Czech Republic. MPs were analysed for fat content, fatty acids (FA) composition and sodium (Na) content. The compliance with legal requirements (Regulation EC No 1924/2006) and information stated on the product was checked.This study is the first one in the Czech Republic dealing with this issue. Among hundreds of marketed MPs, we observed only a limited number of MPs bearing claims. We analysed and compared chemical composition of 12 MPs bearing nutrition claims to 5 identical brand products without any claim. None of the claims dealt with reduced amount of Na/salt content and none was evaluated as an explicit health claim. Most of the mentioned nutrition claims were declared as “Fit, Fitness, Light, Wellness, With low/reduced fat”. Only one claim mentioned “ω3 FA addition”. All analytical results, except one product with claim “Low/reduced fat” or “Light” (if connected with fat reduction), corresponded to the legal requirements and information stated on the product. Three statements on the products associated with Na/salt content did not correspond to the amount measured in the sample. When comparing MPs “with” and “without” nutrition claim, lightly reduced fat or added amount of ω3 FA was recognized only in one product with claim. Other indicators, such as Na/salt content, better FA profile or more evident fat reduction were not found. The results of our study show that claims such as “Healthier, Fit, Fitness or Wellness” may be considered as somewhat misleading for consumers.

Emulsification Capacity

In recent years, consumer concerns regarding high levels of sodium chloride (NaCl) intake have increased, given the associated risk of cardiovascular disease. This has led food industries to consider lowering the use of sodium in food products. However, it is well known that the addition of NaCl to meat products enhances their quality, including water-holding capacity, emulsification capacity, juiciness, and texture. Thus, it is difficult to completely remove salt from meat products; however, it is possible to reduce the salt content using salt substitutes, flavor enhancers, textural enhancers, or other processing technologies. Several recent studies have also suggested that processing technologies, including hot-boning, high pressure, radiation, and pulsed electric fields, can be used to manufacture meat products with reduced salt content. In conclusion, as the complete removal of NaCl from food products is not possible, combined technologies can be used to reduce the NaCl content of meat products, and the appropriate technology should be chosen and studied according to its effects on the quality of the specific meat product.

The article presents the results of the study of changes in flavour characteristics when using corrective additives. Monosodium glutamate, ribotide, yeast extract and hydrolysate of vegetable soy protein were used as flavoring additives (FA). To assess the effect of composition of meat product recipe, as well as the method of FA‑introduction on taste intensity, the recipes of model meat systems with partial replacement of meat raw materials were used. Pork fat, soy protein and potato starch were used as meat substitutes. The effect of recipe composition on the content of non-volatile substances of aroma was accessed. It is shown that replacement of pork by pork fat in the recipe by 20–40% led to a sharp decrease in the concentration of aromatic substances and a decrease in intensity of taste of the finished product several times. The ways for taste correction using FA was studied. For this, a chopped semi-finished product — minced meat was prepared from chilled whole-muscle pork and 0.05% of each FA was added. It is shown that the dynamics of changes in the content of free amino acids is the most pronounced when using monosodium glutamate not as a mono-additive, but in compositions: monosodium glutamate with yeast extract and monosodium glutamate with ribotide. A pool of chemical compounds involved in the formation of taste and aroma of products was detected. The main components were derivatives of C6–C24 fatty acids, as well as a significant number of other biochemical compounds, mainly substituted amines, amides, alcohols and ketones, with a content ranging from 0.001 to 0.2 mg/kg. The results of organoleptic analysis showed that the most delicious and attractive samples were those containing monosodium glutamate with yeast extract and monosodium glutamate with ribotide.

The effects of yeast extract addition, with varied quantities of salt and sugar, on the chemical and mineral composition, colour and sensory properties of spelt bread, in order to obtain new products were investigated. The addition of 5 % yeast extract positively influenced the mineral characteristics and increased protein content by 30.77 %. As a salt substitution, addition of yeast extract improved appearance without deteriorating texture descriptors and breadcrumb quality, while the taste became more complex, but without increasing salty taste. Addition of sugar in samples with yeast extract, improved most sensory characteristics. The developed mathematical models of bread with yeast extract quality parameters were statistically significant, indicating the satisfactory approximation of the bread quality parameters within the varied formula. Bread samples with addition of 5 % yeast extract, 1.5 % of salt and 0 % sugar were determined as the best from the aspect of overall quality. A new product was obtained with good total quality, higher level of nutritional value and reduced salt content.

Indirect competitive ELISA method for the detection of soya proteins in meat products was developed. The detection limit of the method is 0.5% of the weight of added soya protein. A total of 131 meat product samples such as salamis or sausages from the Czech Republic market were investigated for the presence of soya proteins. Soya proteins were detected in 84% of the investigated samples without any declaration on the package of the product. The use of vegetable additives, namely soya in meat products in the market of the Czech Republic is very frequent and the restriction of its usage by legislation relates only to some kinds of durable products and ham (Act 264/2003 Coll.). The need for sensitive inspecting methods for soya protein detection is not only associated with the economic aspect (adulteration), but mainly with consumer health protection in case of allergy to soya proteins.

This study aimed at understanding how the presence or absence of NaCl influences dough rheological performance of soft wheat cvs. currently used in the Italian bread manufacturing industry as a scientific support to national health strategies to reduce the use of NaCl in bread. For this reason 176 flour samples belonging to 41 soft wheat cvs. currently cultivated in Italy, were analyzed for their protein content, Zeleny sedimentation value, and by means of the Chopin Alveograph and Brabender Farinograph, with no salt and with 1.5% salt addition (average salt content in Italian bread). Three selected cvs. (Aubusson, Bolero, and Blasco) were additionally studied by means of the Rapid Visco Analyzer (RVA) at three levels of salt addition (0%, 1.5% and 3.0%). The fermentation behaviour of the cvs. Aubusson and Blasco was also studied by means of a Rheofermentometer under the same conditions. The results of our study confirmed the role of salt in strengthening the wheat gluten network (up to 86%), and thus the gas retention of dough and in affecting yeast activity. However, it also definitely proved that careful cultivar selection can help in overcoming technical challenges in reduced-salt bread manufacturing and eventually, it opens the path to wheat breeding for reduced-salt bread baking.

The quality, safety, and suitability of animal fat for processing of a specific meat product is a critical issue. Increasing the human awareness about the health aspects associated with increased intake of animal fat, makes camel fat a suitable raw material for meat processing due to its excellent nutritional contribution. Therefore, the target of this study is examination of the sensory, physicochemical, fat oxidation, fatty acid profile, and other quality parameters of camel fat to evaluate the feasibility for processing of different meat products. To achieve this goal, 30 fat samples each from the hump, renal, and mesentery of Arabian male camels were investigated. The results showed that both the renal and mesenteric fat had honey color and medium-soft texture, while the hump had greyish-white color and hard texture. The sensory panel scores were significantly different between the hump and other fats. Hump fat had significantly (P<0.05) higher moisture, protein, and collagen content, while higher fat content was recorded in mesenteric fat. The fatty acid analysis showed that hump had high SFA and very low PUFA in comparison with both renal and mesenteric fat. Camel fat had high oxidation stability, and the mean values were very low in comparison with the levels of quality and acceptability. The ultrastructural analysis showed that hump fat had high elastin fibers which increase its hardness. The results indicated that both renal and mesenteric fat were more suitable for the production of various meat products than the hump.

Abstract Objective: The objective is to analyze Danish consumers’ attitudes to buying food with reduced salt content. Design: The study is based on a comprehensive store intervention that included 114 stores belonging to the same supermarket chain. Three different salt claims were tested for eight weeks on six test products within the categories bread, cornflakes and frozen pizzas. Scanner data were supplemented with 134 brief interviews with consumers in nine selected stores. Setting: Stores spread across Denmark. Participants: Consumers who buy food in the stores. Results: Statistical regression analyses of the scanner data indicated that none of the three claims significantly affected demand for any of the test products. The interviews confirmed that many consumers were more focused on other elements of the official dietary advice than reduced salt consumption, such as eating plenty of vegetables, choosing products with whole grains and reducing their intake of sugar and fat. Conclusions: Overall, both the scanner data and the interviews pointed in the same direction, toward the conclusion that salt content is often a secondary factor when Danish consumers make dietary choices.
