Quality Assurance

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Measurement of Bioavailability: Pharmacokinetic Methods

Measurement of Bioavailability: Pharmacokinetic Methods

Pharmacokinetics is a vital branch of pharmacology that examines how drugs are absorbed, distributed, metabolized, and excreted by the body. Two key methodologies in pharmacokinetics are plasma drug concentration studies and urinary drug excretion analyses, both of which provide critical insights into a drug's therapeutic efficacy and bioavailability.Plasma Drug Concentration-Time StudiesPlasma drug concentration-time studies involve analyzing blood samples at specific intervals to quantify...

Measurement of Bioavailability: Pharmacodynamic Methods

Measurement of Bioavailability: Pharmacodynamic Methods

Pharmacodynamic methods provide insights into a drug's effects on physiological processes over time and play a crucial role in understanding bioavailability and therapeutic efficacy. These methods can be broadly classified into acute pharmacological and therapeutic response approaches, each with distinct mechanisms and applications.The acute pharmacological response method directly correlates a drug's physiological effects, such as ECG or pupil diameter changes, to its time course in the body.

Summary

Objective instruments like the fibre optic probe and reflectometer accurately estimate pork quality in chilled cuts. These methods offer reliable, non-subjective assessments for meat quality evaluation.

Background:

Objective assessment of pork quality is crucial for the meat industry.
Traditional methods rely on subjective panel scores, which can be inconsistent.
Instrumental measurements offer a more standardized approach to evaluating meat quality.

Purpose of the Study:

To evaluate several objective instrumental methods for estimating pork quality.
To compare the accuracy of these methods against experienced panel visual scores.
To determine the best instruments for assessing pork quality in both chilled cuts and hot carcasses.

Main Methods:

Correlating instrument values (reflectance, fibre optic probe, pH, drip, Kapillarvolumeter) with expert panel visual scores.
Measurements were taken on intact carcasses and after cutting at various points (shoulder, mid-loin, ham).
Evaluated methods on both chilled pork cuts and hot carcasses.

Main Results:

In chilled pork, the fibre optic probe (FOP(u)) and reflectometer showed strong agreement with panel scores (r=0.71 and 0.78).
The fibre optic probe also provided a useful indication of meat quality in uncut carcasses.
For hot carcasses, the fibre optic probe (FOP(l)) outperformed pH(l) in predicting panel score and reflectance.

Conclusions:

Fibre optic probe and reflectometer are effective objective tools for assessing pork quality in chilled cuts.
The fibre optic probe is advantageous for evaluating uncut carcasses.
Different instruments show varying predictive power for panel scores and drip loss depending on whether the carcass is hot or chilled.
