It looks like you had an interesting and educational conversation with Pete Hansen.
Although Catherine may have sent you a non-specific spec sheet, I note that the Nutrition Facts in what she sent you, as noted at Reply 1605 at http://www.pizzamaking.com/forum/index.php/topic,9068.msg241739.html#msg241739
, are the same as in the specific spec sheet that Pete sent you for the Gangi Supreme Super Heavy Pizza Sauce.
Pete is correct that there is no Standard of Identity for pizza sauce. As you can see from the document at http://www.nfsmi.org/documentlibraryfiles/PDF/20080211094017.pdf
, there are standards of identity for canned vegetables including tomatoes, tomato concentrates and catsup, and also for canned tomato juices. But not pizza sauces. Yet, interestingly, Gangi calls the Gangi tomato product you purchased today a "pizza sauce", and that pizza sauce has an NTSS value, which represents a standard of identity. Maybe they can add dried basil and still assign an NTSS value to the combined puree and dried basil.
It is interesting that Stanislaus and Gangi appear to be processing the same type of tomatoes grown in the same general region. However, that does not necessarily mean that they process the tomatoes the same way. For example, take a look at the Nutrition Facts for the Stanislaus Saporito Super Heavy Puree at http://www.stanislausfoodproducts.com/_pdfs/Saporito-Puree.pdf
. You will note that for the same serving size (1/4 cup, or about 60 grams), the Stanislaus product has a higher calorie count and more Carbohydrates and Sugars. I believe the higher Carbohydrates number is because of more Sugars in the Stanislaus product. Note also how much more Vitamin A and Vitamin C are in the Stanislaus product per serving size compared with the Gangi product. Vitamin C is susceptible to destruction by heat, so maybe Stanislaus uses a lower temperature processing for its tomatoes. It is perhaps also noteworthy that of the 28 tomato products shown at the Stanislaus website, only two products have lower Vitamin C contributions than the Gangi product for a 1/4-cup serving size (they are the 7/11 Ground Unpeeled Tomatoes and the Full Red Chunky Tomato Sauce). If you end up talking with Stanislaus and you mention the Gangi product, you might hear their side of the story.
All of the above is moot, I suppose, since you have the Gangi Supreme product that you were after. In my case, I am only trying to understand what is going on.
