摘要:
The present invention relates to a process for obtaining lipid from a composition comprising cells and water, said process comprising contacting the composition with a desiccant, and recovering the lipid from the cells. The invention also relates to a lipid obtainable by this process. The process according to then invention enables lipid of high quality to be obtained with a high yield, and does not require a heating step.

摘要:
The present invention relates to a composition comprising a polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA) and cells, which composition has a thermal induction time (T.I.T.) of > 24 hours at 40 °C. The invention also relates to a process for drying a composition comprising cells and a LC-PUFA, the process comprising drying the composition at a temperature of below 40 °C.
摘要:
The present invention describes an edible spray-dried particulate composition comprising a solid non-lipid carrier and an oil phase, wherein (i) said oil phase being capable of being released from the carrier on contact with an aqueous medium to form an oil-in-water emulsion; and (ii) the oil droplets in said oil-in-water emulsion have a D[4,3] of from about 100 nm to about 1000 nm; at least about 75% of the oil droplets in said oil-in-water emulsion have a size of less than about 10 μm; or the d90 by volume of the oil-droplets in said oil-in-water emulsion is greater than that of an oil-in-water emulsion used to prepare the composition by less than about 30%. The invention also relates to a method for the preparation of the composition, to food products and food supplements comprising the composition and to uses of the composition.
摘要:
The present invention describes an improved pasteurisation protocol for pasteurising microbial cells is disclosed. The protocol has three stages, a first heating stage, a second plateau stage at which the cells are held at a (maximum and) constant temperature, and a third cooling stage. Both the heating and the cooling stages are rapid, with the temperature of the cells passing through 40 to 70°C in no more than 30 minutes in the heating stage. The heating rate is at least 0.5°C/minute and during cooling is at least -0.5°C/minute. The plateau maximum temperature is from 70 to 85°C. By plotting the pasteurisation protocol on a time (t, minutes) versus temperature (T, °C) graph, one obtains a trapezium having an area less than 13,000°C.minute. Not only does this result in a smaller energy input (and so a reduction in costs), but a better quality (and less oxidised) oil results having a peroxide value (POV) of less than 1.5 and an anisidine value (AnV) of less than 1.0.
