* high uptake of sorbate
)/kg(sorbent) [lb(sor-bate)/lb(sorbent)]; if water is the sorbate
, a high selectivity for water;
There were five preservatives most added in product samples: sorbic acid (E200), potassium sorbate
(E202), sodium nitrite (E250), sodium nitrate (E251) and calcium propionate (E282).
Cd is concentration of sorbate
onto the solution (mgL-1)
The diffusion coefficient (D) is easily obtained from the sorbate
uptake by the blend versus time from the slope of the initial linear sorption curve, according to Eq.
In the range of pyrene concentrations in sorbate
[10.sup.-6]-[10.sup.-8] M an SSF signal was observed only for the laboratory films.
Binding nature is based on type of sorbent and sorbate
, but mostly physisorption or chemisorption takes place .
These adjustments included the elimination of acetic acid from the brine formulation, addition of 6 mM potassium sorbate
, and introduction of a minimal air-purging routine .
Citric acid (E330) also increases the acidity of the food product thus increasing the effectiveness of sodium benzoate and potassium sorbate
since a greater proportion of the acids is in undissociated form .
Marzipan comes as a dough-like compound made from (depending on the brand) a mixture of almonds, sugar, water, bitter almond oil (synthetic), and potassium sorbate
"If you go for the ones which have not got that much sugar in them they've then got aspartame, they've got potassium sorbate
The composition contains a combination of zinc oxide, titanium dioxide and butyloctyl salicylate sufficient to impart the SPF of at least 20 to the composition (wherein the composition does not include any additional physical or chemical UV absorption agents); cyclopentasiloxane; neopentyl glycol diheptanoate; butylene glycol; caprylyl methicone; PEG-9 polydimethylsiloxyethyl dimethicone; glycerin; polyglyceryl-6 polyricinoleate; lauric acid; aluminum hydroxide; potassium sorbate
; and citric acid.
, which is extracted from the berries of mountain ash, is used as a preservative.
There are other anti-contaminants with lower toxicity, such as the sodium benzoate (L[D.sub.50] for rats> 1940 mg.[kg.sup.-1]) (Ma, 2009); potassium sorbate
(L[D.sub.50] for rats of 3800 to 4300 mg.[kg.sup.-1]) (Reckitt Benckiser, 2010); and 2-phenylphenol (L[D.sub.50] for rats of 3200 to 3500 mg.[kg.sup.-1]) (Tayama et al., 1983), all with lower toxicity than formaldehyde (L[D.sub.50] for rats of 100 mg.[kg.sup.-1]) (Deng et al., 2014).
enzymes, vital wheat gluten, cellulose gum, wheat starch, calcium carbonate), calcium propionate, sorbic acid, and/or potassium sorbate
The chromatographic peak at 23.2 min (Figure 3) which corresponds to potassium sorbate
is very intriguing.
