hydrolyzed protein

lately alot of stuff has been popping up about hydrolyzed collagen being in proten bars and how it is a useless source of protein for humans ....... i recently saw a name brand protein powder that lists 100% Hydrolyzed whey peptides as its main source of protein... i was wondering what value this protein source has and if its considered the same as hydrolyzed collagen..... any answers welcome .
 
A lot of the bars use different fillers, you have to watch out for that. I havent read too much about hydrolyzed collagen but I will do a little research. A lot of them say something like "this product contains **** which pretty much does nothing, but is 4 calories per g" in small print at the bottem.
 
Alright, I'll take a stab.

Hydrolysis is simply a process of decomposing a compound. In this case, presumably for ease of digestion/bioavailability. Collagen is collagen, whey is whey. Just because either is hydrolyzed doesn't magically switch it into an entirely different compound.

Now, collagen, it is not of use to skeletal muscles, but your body does put it to use for joints, tendons, ligaments, skin, hair, nails, etc. If you're looking for a muscle-feeding protein source, collagen is not it. But collagen does have its place.

Hydrolyzation, I would think, would seem to cause some denaturing of protein. Whether or not this would damage its amino-acid profile, I don't know. I assume the application that you are looking at is a post-workout drink? Just stick to a nice whey protein isolate (I like CFM); it will be usable quick enough to meet your requirements and will retain it's original amino-acid profile (which is excellent).

P.S. Bars are shit for the most part.
 
Well, w/out all the scientific bullshit, Hydrolyzed means predigested, and it's a perfectly good source of protein if it's whey. Now, no form is collagen is very desireable( hydrolyzed or not) b/c it's missing an essential amino acid, I believe it's L-Histidine or L-Methionine. Thus, it's insufficient to use it by itself, but, since we're talking about a bar that has a blend of protein in it, and since these proteins contain all of the amino's, the make up for the missing one in collagen, and bringing the bioavailibility of the bar back up. Hope that helped.
 
Excerpt from Protein Insider article by TC -- Bars

T: You've also mentioned in previous conversations that the protein bar market has, shall we say, it's own share of problems, too.

PI: Sure. The bars are, for the most part, more deceptive than the protein powders or RTD's.

T: What specifically is the current problem with the bar market?

PI: First of all, Atkins and Balance came out with this position that low-carb bars are possible. They play fakery with the glycerin — they say it's not a carbohydrate when in reality it is, and everybody latched on to that. Glycerin is sweet and it contains calories, so why aren't they considering it a carbohydrate? According to the FDA, it is a carbohydrate. So what if it's metabolized slightly differently? Eat enough of it and you'll get fat.

Anyhow, everyone, including the big guys, are watching Balance and until Balance drops the "low-carb" claims from their labels, it doesn't seem like anybody else is going to be in compliance with the FDA regulations. It's mind-boggling to have what is about a 3 or 4 billion-dollar a year industry lying en masse about carbohydrates.

Listen, there's no such thing as a bar that doesn't contain at least 30 to 40% carbohydrates. I don't care what they say, if you can chew it, it's got 30 to 40 percent carbohydrates. It's not possible not to. If you think your bar of choice is low in carbs, you're deluding yourself.

T: If you hadn't told me this a long time ago, I'd be choking and turning blue right now. Anyhow, onward. Traditionally, what's been the problem in getting large amounts of protein in a bar?

PI: Well, up until very recently, when you put real honest-to-goodness milk protein in a bar as your only protein source, it turned out like shoe leather, literally. You couldn't eat it.

T: What's changed?

PI: Well, there is a new technology that just came out — it took two years to figure this out — to blend everything together and do it in such a way using other novel ingredients to get those high quality proteins in there and get that consistency, texture, moisture, mouth feel, and taste that we all look for.

T: And this technology doesn't rely on using Jell-O, or gelatin, as a protein source?

PI: No, no, zero gelatin and very small amounts of glycerin. What companies often did, and still do, is consider gelatin as part of the protein they claim on the label, and as you probably know, the biological value of gelatin is zero, and so, for example, one of the major protein bars had 40% of its protein coming from gelatin. If they claimed 30 grams of protein, all they really had in there that was worth anything was 18 grams. The other 12 grams aren't worth anything from a bodybuilding standpoint.

T: And these guys aren't in jail?

PI: Ha! And you would never know you were being shorted on protein. If you're eating adequate calories, it's not going to dawn on you that you're shortchanging yourself of protein. What's that feel like if you're eating enough calories and not enough protein? Your brain isn't going to tell you that. So if you're eating two bars a day and you're being short-changed 24 total grams of protein, you're not going to know it, but it might affect your physique or athletic goals over the long term. You'd literally be short one protein meal a day.
