At the very least, avocados should comply with the general quality requirements (see Table 1). At a minimum, Europe almost exclusively requires Class I avocados. Avocados in this class need to be good quality and any defects within the permissible tolerance levels. In no case may the defects affect the fruit flesh, the general appearance of the produce, the quality, the keeping quality and presentation in the avocado packaging.
1. Intact: Avocados must not have any damage or injury affecting the integrity of the produce
2. Produce affected by rotting or deterioration such as to make it unfit for consumption is excluded such as:
3. Clean, practically free of any visible foreign matter: Avocados must be practically free of visible soil, dust, chemical residue
or other visible foreign matter
4. Free from pests
5. Free from damage caused by pests affecting the flesh
6. Free from damage caused by low temperature
7. Have a stalk no longer than 10 mm in length
8. Free of abnormal external moisture
9. Free of any foreign smell and/or taste
10. The development and condition of the avocados must be such as to enable them to withstand transportation and
handling and to arrive in satisfactory condition at the place of destination
The development and state of maturity of avocados must be such as to enable them to continue their ripening process and to reach
a satisfactory degree of ripeness. The fruit should have a minimum dry matter content, measured by drying to constant weight:
- 21% for the variety Hass;
- 20% for the varieties Fuerte, Pinkerton, Reed and Edranol;
- 19% for other varieties, except for Antillean varieties that may show a lower dry matter content.
For importers that ripen avocados, 23% of dry matter for Hass avocados is often a minimum. Maturity must be uniform throughout
the parcel.
The ripe fruit should be free from bitterness.
Avocados are classified in three classes, as defined below:
I. “Extra” Class
Avocados in this class must be of superior quality. They must be characteristic of the variety. They must be free from defects, with the exception of very slight superficial defects. These defects should not affect the general appearance of the produce, the quality, the keeping quality and presentation in the package. If present, the stalk must be intact.
II. Class I
Avocados in this class must be of good quality. They must be characteristic of the variety. The following slight defects, however, are allowed provided these do not affect the general appearance of the produce, the quality, the keeping quality and presentation in the package:
- slight defect in shape;
- slight defects in coloring;
- slight skin defects (corkiness, healed lenticels) and sunburn, provided they are not progressive; the maximum total area should not exceed 4 cm2. In no case may the defects affect the fruit flesh. The stalk, if present, may be slightly damaged.
III. Class II
This class includes avocados that do not qualify for inclusion in the higher classes but satisfy the minimum requirements specified above. Avocados in this class must be of reasonable quality and suitable for human consumption. The following defects may be allowed provided the avocados retain their essential characteristics as regards the quality, the keeping quality and presentation:
- defects in shape;
- defects in coloring;
- skin defects (corkiness, healed lenticels) and sunburn, provided they are not progressive; the maximum total area should not exceed 6 cm2.
In no case may the defects affect the fruit flesh. The stalk, if present, may be damaged.
Additional requirements and permissible tolerances for Class I avocados
- Slight defects in shape
- Slight defects in coloring
- Slight skin defects (corkiness, healed lenticels) and sunburn, provided they are not progressive; the maximum total area should not exceed 4 cm2
- The stalk, if present, may be slightly damaged
- A tolerance of 10% is allowed for fruit that meets Class II standards
- A tolerance of 10% in number or weight is allowed for avocados not meeting the sizing requirements.
The size is determined by the weight or count of the fruit. To ensure uniformity in size between produce in the same package, the following size scale applies:
The difference between the smallest and largest fruit within a package should not be more than 25 g.
In Europe, the preferred sizes for Hass avocados are 16–18, and sometimes 20 per 4 kg box. For the Fuerte variety, 14–16
