Antimicrobial Food Additives: Characteristics, Uses, Effects
In this case, it is in practice nearly always the undissociated acid constituent that
has an antimicrobial action. It is not the hydrophilic acid anions but only the
undissociated compounds, because of their lipophilic characteristics, that can
migrate ...

Listeria, Listeriosis, and Food Safety, Third Edition
At equal pH and equimolar total acid, growth inhibition of L. monocytogenes was
in the following order: acetic > lactic > citric [344]. However, at equal pH and
equimolar undissociated acid concentration, listeriostatic activity was in the
following ...

Disinfection, Sterilization, and Preservation
For many weak acids, the antimicrobial activity is primarily attributed to the
undissociated molecule (Albert, 1985). The equilibrium between undissociated
acid and the less active anion is a function of pH. The dissociation reaction can
be ...

Physico-Chemical Aspects of Food Processing
As the pH decreases, the amount of undissociated acid increases. Thus at pH 3.0
, >98% of acetic acid present is undissociated. at pH 4.76 (i.e. numerically equal
to the pA"a) 50% is undissociated and at pH 7.0 only 0.6% is undissociated.

Organic Acids and Food Preservation
Organic acids can enter the microbial cell only in their undissociated forms, which
diffuse across the microbial cell membrane. This entrance of the acid molecule
then lowers the intracellular pH (pHi) of the cell (Carrasco et al., 2006).

Abstract 60° dislocations which are undissociated have been found in thin
regions of an ion-thinned, deformed silicon specimen. Computer image matching
is used in an attempt to characterise their core structure. Possible reasons for
their ...

Acetic acid, however, has a partition coefficient of between 0.03 and 0.07 (
Gordon and Reid, 1922; Bodansky, 1928; Leo et al., 1971), and therefore exists
in its antimicrobial undissociated form predominantly in the aqueous phase. If the
pH of ...

Molecular Pharmacology V3: The Model of Action of Biology ...
Shanes (1 7 6) mentioned that if a correction is made for the activity of the
concentration Of undissociated base, the activity of this base is found to be a
constant at the various pH values. As long as the receptors for the local
anesthetics are ...

Thermal Food Processing: New Technologies and Quality ...
It has been shown that both the ionized and the nonionized form of an organic
acid can contribute to its inhibitory effect, although the undissociated form is
generally more inhibitory [21]. Some weak acids (e.g., acetic and lactic acids) are
...

Energetics of Photosynthesis
Deamer er al. (1967) and Deamer and Packer (1969) showed that, under
conditions leading to chloroplast swelling, Cl' is taken up, apparently to balance
proton uptake. The movement of ions and undissociated molecules across the
thylakoid ...
