szerszy opis obu procesow
"Ion-Exchange (IE) is a process that separates proteins on the basis of their electrical charge. Unlike CFM, ion-exchange requires the use of various solvents to create an attractive charge on the proteins. Once charged, these proteins migrate toward oppositely charged resin beads in the reaction vessel. The protein can be later removed from the resin beads by reversing the charge to result in a highly purified WPI. IE whey protein isolates contain more than 90% protein content with minimal lactose and no fat. This offers an advantage over whey concentrates in terms of pure protein content.
Although the IE process sounds pretty fancy, there are serious drawbacks to this method. As mentioned above, whey protein is a complex protein made up of manysubfractions that have their own unique effects on health, immunity, etc. and some of these subfractions are only found in very small amounts. The subfractions are really what ultimately make whey the unique protein what it is. Due to the nature of the IE process, the most valuable and health promoting components are selectively depleted. Though the protein content is increased, many of the most important subfractions are lost or greatly reduced, resulting in a denaturing of the protein.
This makes ion exchange isolates a poor choice for a true third-generation whey protein supplement, though many companies still use it as their isolate source due to the higher protein content. IE isolates can be as high as 70% or greater of the subfraction b-lactoglobulin, (the least interesting and most allergenic subfraction found in whey) with a loss of the more biologically active and benefical subfractions.
So, the take home message is the pros of an ion exchange whey is for those who simply want the very highest protein contents per gram, but the cons are that the higher protein content comes at cost; a loss of many of the subfractions unique to whey. Is this acceptable? Read on and you can be the judge.
Cross Flow Microfiltration (CFM) was developed to prevent the problems seen with IE proteins. CFM is a process that uses natural non-chemical ceramic filters to separate whey proteins from a variety of undesirables (i.e. fat, cholesterol, lactose, etc.). Advantages to this process include minimal protein denaturation, preserved proteinsubfractions and a better mineral profile. Because there is some indication that these protein fractions may play a role in appetite regulation, immune functioning, neutralizing free radicals and more, many people prefer CFM since it is better at preserving some of these fractions than IE whey protein. CFM is also generally higher in calcium and lower in sodium than IE as a result of differences in processing methods.
The only drawback of CFM is the price. One of the reasons for the high price is because the first company that developed the process patented the technology and now controls the price. It is a bit higher than making a WPC or IE whey
protein isolate, but you get a better concentration of protein that offers all of the benefits of whey, such as enhanced immune function, decrease blood pressure, and increased nitrogen retention."
w skrocie jedyna zaleta wpi otrzymywanego przez w.i. jest ciut wyzsza koncetracja bialka w suchej masie
minusem jest strata wielu waznych czynnikow biologicznych i nadwyzka uczulajacej beta-laktoalbuminy
widzisz wiec ze cena nie jest niczym uzasadniona bo to produkt slaby jesli chodzi o izolaty
jesli sie upierasz zeby kupic izolat to jest np vitalmax (niecale 200zl za 2500g izolatu cfm), olimp (niecale 220zl rowniez za 2500g izolatu cfm) czy mega pyszny nectar od syntraxa (wychodzi podobnie za 2000g)
ja za te pieniazki wole natomiast 2kg dobrego wpc i 1kg bcaa
tak wiec ani produkt wyjatkowy, ani super jakosciowy, jedynie drogi
