Pre-filing checks

• [ x ] I have searched for open issues that report the same problem
• [ x ] I have checked that the bug affects the latest version of the library

The URL of the recipe(s) that are not being scraped correctly

• https://ricette.giallozafferano.it/Spaghetti-aglio-olio-e-peperoncino.html
  All giallozafferano recipes.

The nutritional value contained in scraper.nutrients() is missing the protein, for example

{'calories': '462 kcal', 'carbohydrateContent': '66.7 g', 'sugarContent': '2.4 g', 'fatContent': '17.8 g', 'saturatedFatContent': '2.59 g', 'fiberContent': '2.2 g', 'cholesterolContent': '0 mg', 'sodiumContent': '497 mg'}

missing 'proteinContent': '8.7 g'.

I checked that this behaviour works on other websites. I tested with https://www.allrecipes.com/recipe/269004/one-pot-spaghetti-with-meat-sauce/ which returns for nutrients

{'calories': '606 kcal', 'carbohydrateContent': '66 g', 'cholesterolContent': '53 mg', 'fiberContent': '2 g', 'proteinContent': '30 g', 'saturatedFatContent': '10 g', 'sodiumContent': '1651 mg', 'sugarContent': '9 g', 'fatContent': '27 g', 'unsaturatedFatContent': '0 g'}

containing the proteins.

Hi @NicolasChagnet, unfortunately this is not a bug but rather how the website structures the information. This sites information is extracted via schema located within the JSON-LD which contains the following nutrition info

"nutrition":{"@type":"NutritionInformation","calories":"462 kcal","carbohydrateContent":"66.7 g","sugarContent":"2.4 g","fatContent":"17.8 g","saturatedFatContent":"2.59 g","fiberContent":"2.2 g","cholesterolContent":"0 mg","sodiumContent":"497 mg"}

which does not contain the protein info. It does appear that information is available elsewhere on the page...

<li>
<span class="gz-list-macros-name">Proteine</span>
<span class="gz-list-macros-unit">g</span>
<span class="gz-list-macros-value">8.7</span>
</li>  

but it is not included in the schema and therefore not gathered by the scraper class.
