Maturity Monitoring Results
Based on consumer sensory research, the Avocados Australia mandated standard for Hass avocado maturity is 23% Dry Matter (DM) at time of harvesting. The Shepard standard is 21% DM. These levels have been shown to be the minimum levels to achieve satisfactory eating quality.
Applied Horticultural Research (AHR) is conducting monthly maturity monitoring from February 2022 to March 2023. The aim of this is to monitor the current level of compliance with DM standards and make comparisons with previously collected data (AV11015).
Random samples of avocados are taken monthly from the Sydney wholesale market and tested for DM percentage as a measure of maturity. DM is assessed using the Hofshi Coring and oven drying method. Click here to view the full sampling and assessment methodology.
AHR provides timely feedback to the supplying packhouse, the results of which remain confidential. Deidentified data is averaged for the wider industry and is presented below.
Figure 1. Average Hass DM content by growing region:

Figure 1 shows the average percentage DM of each 10-fruit sample collected this month. Each bar includes a range of DM values, where for example, 21% includes all values from 21.0 – 21.99. The bars are stacked with a different colour for each growing region.

The Monitoring avocado quality in retail (AV19003) project has been funded by Hort Innovation, using the avocado research and development levy, and contributions from the Australian Government.

The Avocado industry development and extension (AV17005) project team conducted a major study into avocado irrigation in 2021. A summit was held in Brisbane in May 2021 with experienced avocado growers, agronomists and irrigation consultants to review current practices, share experiences, examine global advances, identify knowledge gaps, propose changes and develop best practice adoption strategies.
While the summit had restricted numbers, all of the materials developed and the keynote presentation are available right here in the BPR.

Monitoring critical for fruit quality through the chain
Monitoring is one of the key tools helping the Australian avocado industry meet its target of supplying top-quality fruit to consumers. The Avo Update webinar on 12 May 2021 was a chance for those in the supply chain to learn more about the results of the industry’s retail monitoring, and the latest insights into fruit quality and supply chain temperature management.

The speakers
Noel Ainsworth (Queensland Department of Agriculture and Fisheries) provided valuable insights into fruit quality and supply chain temperatures from grower to ripening/wholesale. Noel explored reasons for poor quality and the recommended best practice to prevent and manage identified issues.
Adam Goldwater (Applied Horticultural Research) followed on with an update on fruit quality trends over the past year. He discussed the key fruit quality issues and the impact of supply chain and retail practices on fruit quality.
Where can I find more information?
The retail quality monitoring results are updated monthly in the Retail module of the BPR: click here. You can also learn more about the avocado supply chain project in the BPR. Five videos from the project exploring the best practice of handling avocados from farm to ripening can be found here (external link), and these are also embedded in the Packhouse and Ripening modules.

The speakers
Noel Ainsworth (Queensland Department of Agriculture and Fisheries) provided valuable insights into fruit quality and supply chain temperatures from grower to ripening/wholesale after sampling five regions for a two-year period for the Avocado supply chain project (AV18000). Noel explored reasons for poor quality and the recommended best practice to prevent and manage identified issues.
Adam Goldwater (Applied Horticultural Research) followed on with an update on the retail performance of avocados after sampling carried out in metropolitan stores during the last 12 months as part of project AV19003. Here, attendees were provided with valuable insights into how quality is tracking at retail and explore trends by retail market city, retail display formats and further quality attributes such as age, ripeness and internal defect levels.
