This disclosure relates to a method for improving a sensory characteristic of a carotenoid composition including providing a carotenoid composition into a reaction vessel and holding the carotenoid composition at a holding temperature between 50 C. to 180 C. while purging atmosphere from the reaction vessel for a suitable time to remove volatile odor-causing impurities from the carotenoid composition. This disclosure also relates to carotenoid food additive formulations prepared according to the above method.

The present invention relates to a margarine substitute loaded with trans-resveratrol/glycoside and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a peanut protein dispersion, adding a transglutaminase thereto, performing a cross-linking reaction under a water bath condition, and heating up to obtain a monolithic gel; continuing to add water to the monolithic gel, shearing the resultant at a high speed, homogenizing at a high pressure, performing ultrasonication, and adjusting pH to obtain a microgel particle dispersion; (2) adding a trans-resveratrol/glycoside to an edible oil in the dark, stirring well, continuing to add the microgel particle dispersion obtained in step (1), and shearing the resultant at a high speed to obtain a high internal-phase Pickering emulsion, i.e. a margarine substitute loaded with trans-resveratrol/glycoside. The trans-resveratrol/glycoside in the margarine substitute loaded with trans-resveratrol/glycoside of the present invention maintains relatively high activity and can solve a series of industrial problems brought by trans fat.

The present invention relates to a process of compacting a microporous fat powder, notably a microporous fat powder that can suitably be used as an oil structuring agent.

One aspect of the invention relates to a process for compacting a microporous fat powder, said process comprising: feeding the fat powder into the feed zone of an extruder having a forwarding screw and a barrel within which said screw is centrally positioned; rotating said forwarding screw to advance said fat powder feed through a compacting zone of the extruder where the barrel comprises a plurality of venting openings having a shorter dimension that exceeds the volume weighted average diameter of the fat powder feed and that is less than 10 mm; and expelling the compacted fat powder from the extruder;
wherein the temperature of the fat powder during passage through the extruder is maintained below 40 C. and wherein the compaction factor achieved exceeds 1.5

Another aspect of the invention relates to a compacted microporous fat powder having the following characteristics: a freely settled density in the range of 90-600 g/l; a particle size distribution with at least 90 vol. % of the particles having a diameter in the range of 20 to 600 m; a maximum G.sub.i/G.sub.d ratio of more than 2.0, wherein G represents the elastic modulus at 10 C. of a dispersion of 2 wt. % of the compacted fat powder in glycerol, and wherein the maximum ratio is determined by recording G.sub.i whilst increasing the frequency from 0.1 to 15 s.sup.1, by subsequently recording G.sub.d whilst decreasing said frequency from 15 to 0.1 s.sup.1, and by calculating the ratio G.sub.i/G.sub.d at the frequency at which said ratio is highest.
