url rich keyword duplicate

[Alen]

Hi all,
i'm going live with my site with all url rich keyword...something like:
/company-e-snack-solido-company-brandname-power-sport-competition-bar-5-bar-da-40-gr-cad~P1621

Now...I want send to google sitemap all flavors urls for that product, something like look between (...):

/company-e-snack-solido-brandname-(vanilla)-brandname-power-sport-competition-bar-5-bar-da-40-gr-cad~P1621

/company-e-snack-solido-brandname-(cioccolate)-brandname-power-sport-competition-bar-5-bar-da-40-gr-cad~P1621

/company-e-snack-solido-brandname-(orange)-brandname-power-sport-competition-bar-5-bar-da-40-gr-cad~P1621

company-e-snack-solido-brandname-(apple)-brandname-power-sport-competition-bar-5-bar-da-40-gr-cad~P1621

This the question.
All URLS with flavors specific have an permanent redirect 301 to the real URL with no flavor specific...but this tecnique can be penalize?

I want that google indexe all flavors but don't want my product can be an span index.

I must send only one (without flavor) or all but redirect the 5 urls at same product to one of theme.
Thanks, Alen Italy

Hello Alen, and welcome to the forums,

Here's a comment from JohnMu at Google:

...you need to list the final URLs in your Sitemap file. They should not be redirecting elsewhere.

Google Webmaster Forum [google.com]

So my advice is not to take this approach. Keywords in the file path are not a big factor. And unless you are using an automated appraoch that needs to create such a long file-name, I would suggest making your urls much shorter
