Influence of the addition of KCl and CaCl2 blends on the physicochemical parameters of salted meat products throughout the processing steps

The objective of this study was to evaluate the effects of different chloride salts (NaCl, KCl, and CaCl2) on the characteristics of salted meat products through the determination of moisture, pH, aw, chloride, ash levels, cooking loss, and instrumental color during the processing steps. Four salted meat treatments were elaborate using the following salts in the wet and dry salting steps: FC1: 100% NaCl; F1: 50% NaCl + 50% KCl; F2: 50% NaCl + 25% CaCl2; F3: 50% NaCl + 25% KCl + 25% CaCl2. The addition of CaCl2 led to the lowest pH and changes in aw, moisture, ash levels, and instrumental color when compared to the other treatments, which was different from the control (100% NaCl) and F1 (50% NaCl + 50% KCl), thus evidencing the great effect of CaCl2 on the characteristics of salted meat products during the whole processing. The partial replacement of NaCl by KCl and/or CaCl2 greatly increased the cooking loss of salted meat products. The replacement of NaCl by KCl promoted similar quality parameters

Substitution Effects of NaCl by KCl and CaCl2 on Lipolysis of Salted Meat

The objective of this study was to investigate the reduction and partial substitution effects of sodium chloride (NaCl) by potassium chloride (KCl) and calcium chloride (CaCl2) on lipolysis and lipid oxidation in salted meat aiming at reducing sodium content. To evaluate the effect of different salts on lipid oxidation thiobarbituric acid-reactive substances (TBARs) assay was performed along 180 days. Furthermore, ESI-MS/MS and GC analysis were conducted to detect and identify oxidized lipids, volatile compounds and free fatty acids profiles during the meat processing time. Lipid profiles from different salted meat demonstrated that CaCl2 salt have inducted more lipid oxidation when compared to the combination of NaCl and KCl salts, highlighting the implication of CaCl2 on increased lipolysis reactions. Moreover, the obtained results from both the analyses suggest that a combination of NaCl and KCl salts can be a good alternative for reducing the sodium content without compromising the quality of the salted meat

Beta vulgaris as a natural nitrate source for meat products: A review

Curing meat products is an ancient strategy to preserve muscle foods for long periods. Nowadays, cured meat products are widely produced using nitrate and nitrite salts. However, the growing of the clean-label movement has been pushing to replace synthetic nitrate/nitrite salts (indicated as E-numbers in food labels) with natural ingredients in the formulation of processed foods. Although no ideal synthetic nitrate/nitrite replacements have yet been found, it is known that certain vegetables contain relevant amounts of nitrate. Beta vulgaris varieties (Swiss chard/chard, beetroot, and spinach beet, for instance) are widely produced for human consumption and have relevant amounts of nitrate that could be explored as a natural ingredient in cured meat product processing. Thus, this paper provides an overview of the main nitrate sources among Beta vulgaris varieties and the strategic use of their liquid and powder extracts in the production of cured meat products.Fil: Munekata, Paulo E.

Physical properties of emulsion gels formulated with sonicated soy protein isolate

This study aimed to determine the effect of high-intensity ultrasound (HIU) on physical properties of soy protein isolate dispersions (SPI) and their addition to emulsion gels (EG) containing soybean oil (SBO), inulin (IN) and carrageenan (CAR). Sonicated and non-sonicated SPI dispersions were mixed with CAR, IN and SBO and heated at 90 degrees C for 30 min to gel the emulsion. An increase in solubility and oil binding capacity was observed in sonicated SPI dispersions (S-SPI) compared to the non-sonicated ones. HIU changed the molecular weight of SPI and decreased apparent viscosity in the dispersions. The use of S-SPI in the EG reduced the droplet size and increased the hardness and G ' values. The use of S-SPI allowed a reduction of 75% of carrageenan in the EG without affecting the hardness of the gel. The results suggest that HIU can be used to improve rheological properties of functional EG542451459COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP88881.135401/2016-012016/19967-

Understanding the effect of different chloride salts on the water behavior in the salted meat matrix along 180 days of shelf life

The objective of this study was to evaluate the effects of different chloride salts (NaCl, KCl, and CaCl2) on water behavior in salted meat during 180 days of shelf life by Low Field Nuclear Magnetic Resonance and physicochemical analysis. Four salted meat treatments were made using the following salts in the wet and dry salting steps: FC1: 100% NaCl; F1: 50% NaCl + 50% KCl; F2: 50% NaCl + 50% CaCl2; F3: 50% NaCl + 25% KCl + 25% CaCl2. The analyses performed were: moisture, pH, aw, weight loss and Low Field Nuclear Magnetic Resonance. The use of CaCl2 as a salt substitute to NaCl during the elaboration of salted meat caused a decrease of pH and higher values of aw and weight loss when compared with the treatments containing only NaCl or NaCl + KCl. The morphology of the salted meat changed with the addition of CaCl2, possibly making the matrix structure more open and facilitating dehydration, whereas the NaCI replacement by KCI did not cause significant modifications in salted meat characteristics during 180 days of storage. In general, the results demonstrated that the addition of KCl may be a good alternative to reduce the sodium content in salted meat product, and the Low Field Nuclear Magnetic Resonance method has proved a good tool for obtaining additional information on the changes that salts can cause in the structure of salted meat products125CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQ140533/2015-0, 406671/2016-

Is there a potential consumer market for low-sodium fermented sausages?

The NaCl levels in dry fermented sausages were reduced by 50% or were substituted with KCl, CaCl2, or a blend of KCl and CaCl2 (1: 1). The quality, safety, and the potential consumer market of dry fermented sausages were assessed. Neither 50% reduction of the NaCl content nor the substitution of 50% of the NaCl with KCl influenced the fermentation and maturation process. However, when CaCl2 was used as the substitute salt (50%), there was a significant decrease in pH, an increase in the water activity, and a decrease in lactic acid and micrococcus bacterial counts. Overall, the sensory acceptance decreased in dry fermented sausages with reduced sodium content. However, cluster analysis and internal preference mapping revealed potential for commercialization of samples with 50% of the NaCl content substituted with KCl or with a mixture of KCl and CaCl2 (1:1).805S1093S109

Cheeses with reduced sodium content: Effects on functionality, public health benefits and sensory properties

The development of food products that may contribute to attenuate issues related to public health in a positive way is a challenge for the dairy industry. Due to its negative effects of salt on health, such as increase in blood pressure and decrease in calcium absorption, high intake of salt derived from food in industrialized nations is an important issue for the modern society. Considering that cheese consumption is increasing worldwide, importance should be given to reducing the contribution of salt as a sodium-carrier without affecting its consumption. Various types of cheese have been developed with reduced sodium content by decreasing NaCl or partial/total substitution of this salt with KCl, MgCl2 and CaCl2. The results are mostly positive; most variety of cheeses is acceptable, but at times there is a sour residual taste resulting from the substitution of NaCl. Further knowledge is necessary regarding the quality of cheese and levels of salt that is acceptable in the production of cheeses with reduced sodium content

Impact of sodium chloride replacement by salt substitutes on the proteolysis and rheological properties of dry fermented sausages

The effect of a 50% reduction of NaCl and its replacement by KCl, CaCl2, and a blend of KCl and CaCl2 (1:1) on the proteolysis and rheological properties of dry fermented sausages was investigated. The reduction or replacement of NaCl by KCl did not cause changes in the electrophoretic profile and the addition of CaCl2 decreased the degradation of sarcoplasmic proteins during the manufacturing process. Samples with a 50% reduction of NaCl showed a higher content of the amino acids Arg, Glu, His, Val, Cys, Lys, and Trp, whereas the samples containing CaCl2 had a higher content of the amino acids Asp, Thr, Ala, Met, Leu, Ile, and Phe. The reduction or replacement of NaCl by KCl decreased sample firmness, whereas the addition of CaCl2 increased the hardness of the samples1511624CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçã
