    [Egg White Protein Powder] Why does my egg white protein powder becomes brown?

    Hi guys xD

    if you know someone who might help me with this, please tag the user.


    So I'm doing this because of the avidin issue. I just want to heat up this crap and put it in my yogurt to eat.
    I'll be eating 60g of egg white protein powder, its like eating 15 eggs per day.
    This **** blocks the avidin absorption, I dont want this effect, so I have to burn this thing.

    ht tps:/ /ifst. onlinelibrary.wiley. com/doi/abs/10.1111/jfpp. 12154

    Apparently, to neutralize avidin almost completely, one must submit the egg white to a temperature of 100C for 10min. There is an even older study that says 4min. This for avidin in egg whites.

    My oven is old and I don't know the temperature. I did some tests and it looks like it heats up to 200-250C. From what I've researched on microbiology, at this temperature it would probably(I need the Z value for this, and its not shown in the study preview, but it probably is not very high from what I've seen in other study) take about 1 minute to neutralize all avidin. The problem is that the egg white protein quickly turns brown as in the photo (I took it). If I leave it for too long like 10min, it turns black, carbonizes, turns into charcoal. Does anyone know why it turns brown? Maiilard Reaction? My fear is the amino acids are being destroyed and charred quickly.

    Tbh I'll test tomorrow to see what happend under only 1min, But I'm sure that under like 3minutes it becomes brown..

    I could just make a recipe that goes in the oven, like a protein bar. I believe this does not happen with the powder in the case of the recipe because the thermostability of the protein in the mixture is different.

    it is pasteurized, but pasteurization is at 65C for 2 minutes. this neutralizes very little of the avidin.

    3min:
    ht tps: //i.imgur. com/RlXPt0I. png

    10min:
    ht tps: //i.imgur. com/KsLoPlH. png

    am I crazy? Something says to me its obvious that the brown is still ok to eat.. something else says it can be a transient phase that is already turning to coal and partially destroyed

    When I put my white sneakers in the oven, they turn brown. If I leave them too long, they turn black. Does anyone know why this is? Maiilard Reaction?

    I put my college room mates rubber sneakers in the freezer one evening. He had to make the 1.5 mile walk to class in frozen rubber sneakers the next morning. Did some other mean things to him that I will save for another post which is appropriate for the context of the thread.

    I was pretty big at the time and he was a vegetarian. The threat of violence was not an issue for me.

    I always say that if you are going to make fun of someone, that you should first walk a mile in their shoes. That way you are a mile away from them, and you have their shoes.

    I make fun of people all the time that are living out of a motel room. I tell them that they can pay less money and stay in a place where they can cook food, do their laundry and have more space than a motel room.

    Punchline I tell these people is that they have low standards and no value of money. It goes right over their head.
