| Summary: | Suitability of polysulfone ultrafiltration membranes (UFM) commercial
designed for water treatment have been investigated for separation of protein
(PR) from sweet whey. Ultrafiltration (UF) of whey originated from dairy has
been realized by self-made pilot plant which has been in service about one
year. Influence of two whey temperatures (9 oC and 30 oC) on efficiency of
protein concentration has been examined. Application of investigated UF
elements has given whey protein concentrate (WPC) with 5 to 6 times excess
amount of protein content in regard to starting one. In the same time the
prevalent content of lactose has been removed to permeate. Better results
have been occurred during the cold whey filtration. Besides the fact that
molecular weight cut-off (MWCO) of investigated membranes were 50-100 kDa,
results showed very successful concentrating of whey proteins of dominantly
lower molar weights than 50-100 kDa. Investigated membranes are beneficial
for design and construction of UF plants for exploitation in small dairies. |
