^^^ What's been said above ^^^
Your keyword strategy is just one element of your overall product page presentation.
Over the years, 25 of SEO now and yes SEO existed from the very start, I have created a standardised template for my widgets. The layout is identical for every page so that anyone visiting will always see the pertinent information in the same position, obviously all the keywords, descriptions and images are unique.
Therein lies getting the balance correct and keeping it totally natural and flowing.
I have absolutely no idea if my layouts would work for other global industries however I cannot see why not.
Title: XYZ (Brand Name) Green Fruit Juice
This is always an argued point!
Some favour as you show, some say:
1. Green Fruit Juice | Brand Name
some say:
2. Green Fruit Juice | Light Green Fruit Juice | Dark Green Fruit Juice | Brand Name.
I have used all methods successfully, the big advantage of 2 is that it may be more helpful to some purchasers.
