The Tenderized "Flower" Octopus Treatment: What It Is and Who Buys It

What is tenderized "Flower" octopus?

Tenderized Treatment is a mechanical process applied to whole octopus before freezing. The process softens muscle fibers to produce a more supple, ready-to-cook texture, while preserving the full structure of the piece — eight arms, emptied head, no breakage. The tenderization is done at the Maurimar production facility in Nouadhibou, Mauritania, as part of the standard processing sequence, before the octopus enters the freezing step.

The industry alias "Flower" — an English rendering of the French fleur — comes from the visual result: after tenderization, the tentacles splay outward from the mantle in a petal-like radial pattern. The presentation is distinctive and immediately recognizable in a carton. "Flower" is an industry shorthand, not a trademark — the formal name used in purchase orders and documentation is Tenderized Treatment.

Maurimar offers the Tenderized Treatment on both product lines — Fresh Frozen Japan Quality and Iced — across all calibers T1 through T7, in IQF or block format. Buyers who do not specify a treatment receive whole (emptied head) product by default.

Why is octopus tenderized before freezing?

The practical reason is kitchen time. Whole untenderized octopus — particularly larger calibers — requires significant cooking time or a manual pre-tenderizing step (boiling, beating, or pressure cooking) to reach the texture that grill, plancha, and salad applications demand. When the Tenderized Treatment is applied at the production facility before freezing, the buyer's kitchen receives a product that is already prepared for the final heat step. For high-volume food-service operators and processors working under time pressure, this is a meaningful operational advantage.

The second reason is texture consistency. In a carton of Flower octopus, every piece has been through the same tenderization process under the same controlled conditions. The result across the carton is uniform — which matters for restaurant groups and processors who need predictable cooking behavior across large volumes, not variation between individual pieces.

Tenderized Treatment is less suited to raw and sashimi applications. Japanese buyers who source Japan-quality octopus for sashimi bars typically specify whole (emptied head) product — the firm, intact texture of untreated octopus is what that channel requires, and the mechanical treatment is not part of the sashimi-bar preparation workflow.

How does mechanical tenderization work?

The whole octopus passes through a mechanical tenderizing step at Maurimar's Nouadhibou facility. The process physically softens the muscle fibers without disrupting the external structure of the piece — the tentacles, suckers, and mantle remain intact. No chemical additives are used; the tenderization is entirely mechanical. The step is performed under ONISPA-certified procedures, at the same point in the production sequence as other treatment routing decisions — after cleaning and sizing, before freezing. For the full six-step process, see Maurimar's process page.

The Flower presentation — splayed tentacles radiating from the mantle — is a direct result of the mechanical process, not a separate shaping or trimming step. After tenderization, the octopus freezes with the tentacles in the Flower configuration. When the carton is opened, the pieces are visually distinct from whole product and immediately recognizable by buyers familiar with the format.

What buyers typically order Flower octopus?

Mediterranean food service — France, Spain, Italy, Portugal: The highest-volume Flower market. Grilled octopus, octopus on the plancha, and pulpo a la gallega (Galician-style boiled octopus with olive oil and paprika) are preparation formats where the tender texture of Flower product cuts kitchen time substantially. Spanish and Portuguese distributors supplying tapas restaurants routinely specify Tenderized Treatment as the default.

United States: Ethnic food distributors, food-service processors, and operations making octopus salad or octopus cocktail frequently import Flower product. US buyers are often working with chilled or frozen ready-to-plate products where speed of preparation is built into the supply chain. Tenderized Treatment reduces the processing step at the US facility.

Whole (untenderized) buyers: Sashimi bars and premium EU retail buyers specifying whole-piece display typically order untreated whole (emptied head) product. Hotel groups in the UAE and Saudi Arabia that serve octopus as a whole-piece visual centerpiece also tend to specify untreated product. For these channels, the firm bite of untreated octopus and the intact, unaltered presentation are part of the product's value.

Tenderized vs whole — which treatment fits your channel?

The table below compares both treatments across the criteria that matter in a procurement decision. For the full specifications including treatment options and packaging, see Maurimar's specifications page.

Which product lines and calibers are available with Flower treatment?

Maurimar applies the Tenderized Treatment across both product lines and all seven calibers. Fresh Frozen Japan Quality with Flower treatment is available for buyers who want the same-day-freeze quality of the Japan grade combined with the pre-tenderized texture for grill or plancha applications. Iced grade with Flower treatment is the standard choice for food-service operators and processors where the same-day-freeze premium is not required. For the caliber chart and weight ranges, see the octopus caliber guide.

Both IQF and block-frozen formats are available with Tenderized Treatment. IQF is the default for food-service buyers who want to portion from a loose carton; block is available for processors who handle full-block defrost in their production line. Treatment preference — Flower or whole — is specified on the quote request form along with grade, caliber, format, quantity, and destination port.

Frequently asked questions

Whether the right treatment is Flower or whole depends entirely on the end application — if the answer is clear from your channel, specify it on the quote form and Maurimar applies it at the production step before freezing.
