Using the water bath technique for low-acid foods (foods with pH greater than 4.6). [15] Otherwise correct water bath or pressure canning but processing for too little time, the wrong pressure, or not considering variations in time/pressure due to altitude. Re-using one-use seals; Using cracked or chipped jars
Wash and drain the tomatoes, then score a shallow X in the bottom of each tomato. Blanch the tomatoes in a pot of boiling water — just long enough for the skins to soften and loosen, about 30 ...
An enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors .
Canned tomatoes, or tinned tomatoes, are tomatoes, usually peeled, that are sealed into a can after having been processed by heat. [1] Economic aspects.
To sell juice wholesale, the juice must undergo a process that achieves a "5 log reduction in bacterial plate count." [ 11 ] The process must reduce the amount of microorganisms by 100,000 times. There are several processes available that can achieve a 5- log reduction , including heat pasteurization and ultraviolet light filtering, but the ...
in what is known as the Horeau effect [3] the relationship between mole based ee and optical rotation based ee can be non-linear i.d. in the succinic acid example the optical activity at 50% ee is lower than expected. the specific rotation of enantiopure 1-phenylethanol can be enhanced by the addition of achiral acetophenone as an impurity. [4]
Enantiopure compounds consist of only one of the two enantiomers. Enantiopurity is of practical importance since such compositions have improved therapeutic efficacy. [ 26 ] The switch from a racemic drug to an enantiopure drug is called a chiral switch .
A frigorific mixture may be used to obtain a liquid medium that has a reproducible temperature below ambient temperature. Such mixtures were used to calibrate thermometers. In chemistry a cooling bath may be used to control the temperature of a strongly exothermic reaction. A frigorific mixture may be used as an alternative to mechanical ...
