Summary
This study reveals how activated brines penetrate meat, improving hydration and protein properties. Ultrasound enhances these effects, leading to better meat structure and faster biochemical changes.
Area of Science:
- Food Science
- Meat Science
- Biophysics
Background:
- Understanding brine diffusion in meat is crucial for processing.
- Traditional methods like jetting have limitations in brine penetration.
- Meat protein hydration impacts texture and quality.
Purpose of the Study:
- To investigate the kinetics of activated brine diffusion in meat.
- To explore the role of microstructure and nuclear magnetic resonance (NMR) relaxation.
- To evaluate the impact of ultrasound on meat hydration properties.
Main Methods:
- Microstructure analysis of meat.
- Nuclear magnetic resonance (NMR) relaxation measurements.
- Kinetics study of activated brine diffusion.
Main Results:
- Activated brines diffuse into both interfibrillar and intracellular spaces of meat.
- Ultrasound treatment positively enhances the hydration properties of pork proteins.
- Significant changes in meat structure and component redistribution were observed.
Conclusions:
- Spray penetration of activated brines, especially with ultrasound, offers superior results compared to jetting.
- Enhanced diffusion leads to accelerated biochemical processes and improved meat quality.
- This research provides novel insights into meat modification mechanisms.

04:08Determining the pH of Salt Solutions
48.2K
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution. In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...

01:11Aryldiazonium Salts to Azo Dyes: Diazo Coupling
3.7K
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para...

01:14Nucleophilic Aromatic Substitution of Aryldiazonium Salts: Aromatic SN1
2.8K
Treating arylamines with nitrous acid gives aryldiazonium salts that are effective substrates in nucleophilic aromatic substitution reactions. The diazonio group in these salts can be easily displaced by different nucleophiles, yielding a wide variety of substituted benzenes. The leaving group departs as nitrogen gas, and this easy elimination is the driving force for the substitution reaction.
In the Sandmeyer reaction, for example, the diazonio group is replaced by a chloro, bromo,...

01:261° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
3.9K
Nitrous acid and nitric acids are two types of acids containing nitrogen, among which nitrous acid is weaker than nitric acid. Nitrous acid with a pKa value of 3.37 ionizes in water to give a nitrite ion and the hydronium ion.
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...

01:371° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Mechanism
4.9K
Nitrous acid is a relatively weak and unstable acid prepared in situ by the reaction of sodium nitrite and cold, dilute hydrochloric acid. In an acidic solution, the nitrous acid undergoes protonation when it loses water to form a nitrosonium ion—an electrophile. Nitrous acid reacts with primary amines to give diazonium salts. The reaction is called diazotization of primary amines.
