    Notes: Abstract At a pilot-plant scale, various patented processes for preparation of sunflower isolates were examined. The objectives of these processes are to improve the quality of the isolates (particularly their protein content), to reduce their content of glucidic substances (which obstruct spinning) and to improve their color. A correlation exists between these parameters and isolate yields. Our results, obtained with industrial meals, should be largely improved with respect to yield and color with meals obtained from dehulled kernels which have not been subjected to as much heat-treatment as the industrial meals.

    Notes: Abstract The use of various water-alcohol mixtures to remove antinutritional and technologically inconvenient factors from rapeseed and sunflower defatted meal is described. Meals obtained from dehulled seeds were repeatedly extracted with methanol, ethanol, propanol, isopropanol or isobutanol and water (50 or 60% V/V), at pH 6 at room temperature. Use of methanol, ethanol and isopropanol led to protein concentrates with very high nitrogen yields. These products exhibited low residual contents of soluble carbohydrates, and polyphenols and, for rapeseed, glucosinolates. Moreover, they were bland flavoured and white coloured.

    Notes: Acetylation, which acts on the amino groups of proteins, allows to increase the solubility and the emulsifying properties of pea isolate. Acetylation by acetic anhydride was carried out in a torus microreactor in semibatch and continuous conditions. The mixing characteristics, obtained by a residence time distribution (RTD) method, are the same in batch and continuous processes. The maximum acetylation degree reached by the torus reactor is higher than with the stirred reactor. Torus reactors are more efficient than stirred ones as shown by a conversion efficiency, defined by the quantity of modified lysine groups by consumed acetic anhydride. © 1997 John Wiley & Sons, Inc.
