Due to thermolability
and photodecomposition of lutein and zeaxanthin , CGM should be pretreated in low energy and at low temperatures, whereas the previous pretreatment technology in particular accounts for most of energy consumption, which can cause degradation and loss of activity of lutein and zeaxanthin .
To explain these variations, two major hypotheses were adopted: (i) the decrease in tocopherols level would be due to their thermolability
; (ii) the increase would result from a better extraction due to the destruction of the tocopherol-retaining cellular structures and rupture of their binding to membrane proteins and/or phospholipids [4, 31, 32].
This drying process protects the compound oxidation and volatilization processes, and it is highly recommended for products that have high thermolability
(Shaikh et al., 2006).
Moreover, percolation methodology does not involve heating, an important aspect taking into account the thermolability
of some phytoconstituents.
Inactivation of G-POD was observed after only 1 min at 65[degrees]C or higher temperatures, showing its great thermolability
and a first-order kinetic, however at times longer than 1 min, there is an obvious deviation from linearity.
Due to their thermolability
, antiviral agents were added through filter sterilization by Millipore filter of 0.22 m upon media autoclaving.
Such [beta]-1,3(4)-glucanase was not initially developed specifically for the use in animal feed and hence may not be ideally suited for this application in terms of their physicochemical properties such as its thermolability
. For example, the endo-[beta]-1,3(4)-glucanase purified from R.
The authors purified and characterized HO isoforms from liver microsomes and reported the differential response of both enzymes to different purification steps, thermolability
, activity and response to cobalt, cadmium, hematin, phenylhydrazine, and bromobenzene.
In addition, to assess thermolability
of the compounds, the plant extracts were boiled before addition to the artificial diet; toxicity was tested at the same concentration and experimental conditions as above.
Further considerations when orthopaedic procedures are done in a patient with OP are the intense heat and thermolability
of the hard and soft tissue caused by a compressed-air drill-bit.
