Descending order
The order of the list indicates proportion. The quantity of ingredients alone does not determine the quality of the product. Compare the composition, the function of the ingredients, and the suitability for the intended use.

The label is the product's first document
Olive oil, canned goods, sausages, and Portuguese cheeses provide regulated information — origin, ingredients, allergens, and deadlines — but visual seals do not always mean official certification.
An informed consumer compares the ingredient list, country of origin, and storage conditions. This guide is editorial: it guides reading critically and does not replace the official information on the label or the rules applicable to the market where the product is sold.
The essential points of a label
Points mentioned in this guide — without inventing mandatory fields beyond the editorial content.
01
Ingredient list
Locate the list — the order indicates proportion (reading in descending order).
02
Allergens
Identify highlighted allergens — in this guide: gluten, milk, nuts.
03
Origin
Check the country of origin and packer. Compare with the objective information on the label.
04
Official vs decorative seals
Compare official DOP/IGP seals with decorative symbols. Not every visual seal is certification.
05
Validity and preservation
Observe the expiration date and preservation conditions indicated on the label.
06
Batch
Keep the label if there is any doubt about the batch. Batch and validity matter in imported products.
07
Olive oil (when applicable)
For olive oil, look for variety, acidity, and extra virgin when applicable.
08
Canned goods (when applicable)
For canned goods, note drained weight versus liquid.
How to interpret the ingredient list
Read ingredients in descending order and compare what is written — not what the packaging visually suggests.
Sugar and salt
Do not ignore hidden sugar or salt in the middle of the list.
Names and translation
Translation in Brazil may use different names — compare the base ingredient.
Vague terms
Be wary of vague terms like “artisanal” without context. Do not assume homemade artisanal in an industrial product.
Allergens and warnings
Check highlighted allergens on the official label. This guide does not invent complete legal lists.
Highlight on the label
Identify highlighted allergens. Examples mentioned in this guide: gluten, milk, nuts.
Canned goods and gluten
To check if a canned good is suitable for those avoiding gluten, do not conclude solely based on the expression “modified starch.” Check the origin of the ingredient, the allergen declaration, and the indication about gluten present on the label applicable to the market.
In case of dietary restrictions, consult the official label of the product and, when necessary, seek professional guidance. Highlighting rules may vary according to the market.
Origin and provenance
Confirm origin in the text of the label — not just in the image of the packaging.
Country of origin and packer
Check the country of origin and packer. The location of the company on the packaging should not be interpreted alone as a guarantee of origin.
Flag ≠ guaranteed origin
Common mistake: confusing the image of a flag with guaranteed origin. The objective information is in the text of the label.
Seals, symbols, and certifications
Differentiate marketing from official DOP/IGP. Visual seals do not always mean official certification.
Official vs decorative
Compare official DOP/IGP seals with decorative symbols. Coats of arms, medals, flags, or landscapes do not alone prove protected origin.
DOP and IGP
DOP and IGP are distinct regimes. In DOP, the raw materials and all stages of production are linked to the defined geographical area. In IGP, at least one stage of production, transformation, or preparation occurs in the region. Not every Portuguese product has these indications.
Information and interpretation
The label provides objective data; interpretation should consider the type of product and the market. Advertising text does not replace the essential information on the label.
Criteria
Read with criteria: do not interpret any visual seal as absolute certification. When in doubt, keep the label and check the full name of the indication.
Validity, batch, preservation, and imported products
Follow the conditions indicated on the manufacturer's label — this guide does not replace them.
1
Validity
Observe the indicated expiration date.
2
Preservation
Observe the preservation conditions on the label.
3
Batch
Keep the label if there is any doubt about the batch.
4
Imported
Batch and validity matter in imported products. Translation in Brazil may use different names — compare the base ingredient.
5
Olive oil
For olive oil, check the declared category, origin, validity, and preservation conditions. Acidity and harvest year should be considered when stated on the label. In virgin and extra virgin olive oils, the harvest year is an optional indication and can only be presented when 100% of the content of the package comes from a single harvest year.
6
Canned goods
Note drained weight versus liquid.
How to compare two products
Editorial checklist based on this guide.
- Compare the ingredient list (order and clarity).
- Check highlighted allergens.
- Confirm country of origin and packer.
- Differentiating official DOP/IGP from decorative symbols.
- Observe validity and preservation.
- For olive oil: variety, acidity, and extra virgin when applicable.
- For canned goods: drained weight versus liquid.
Supports mentioned in the guide
- Barcode reading apps can assist in comparison, but do not replace the official label and may present incomplete or outdated information.
- Direct purchase does not replace the need to check identification, origin, batch, validity, and preservation conditions when applicable.
Signs of attention and common errors
- Confusing the image of a flag with guaranteed origin.
- Ignoring hidden sugar or salt in the middle of the list.
- Assuming homemade artisanal in an industrial product.
- Interpreting a visual seal as absolute certification.
Frequently Asked Questions
Are DOP and IGP the same?
No. DOP and IGP are distinct regimes. In DOP, the raw materials and all stages of production are linked to the defined geographical area. In IGP, at least one stage of production, transformation, or preparation occurs in the region. Not every Portuguese product has these indications.
Extra virgin olive oil in Brazil?
For olive oil, check the declared category, origin, validity, and preservation conditions. Acidity and harvest year should be considered when stated on the label. In virgin and extra virgin olive oils, the harvest year is an optional indication and can only be presented when 100% of the content of the package comes from a single harvest year.
Canned goods without gluten?
Check the allergen declaration and the indication about gluten on the label. The expression “modified starch,” alone, does not allow concluding whether the product contains gluten or not.
Food safety
Adjust ingredients and techniques according to dietary restrictions, allergies, proper preservation, and professional guidance when necessary.
