Guacamole Cup Packaging: Color, Chunks & MAP
Preserve the texture, colour, and freshness of avocado-based products. The SDH-R fills chunky guacamole without crushing while MAP nitrogen flushing prevents browning.
Guacamole and avocado-based dips are among the most challenging products to package automatically. The product is delicate — chunks of avocado must not be crushed during filling — and extremely sensitive to oxidation, turning brown within hours without proper atmosphere control. The SDH-R addresses both challenges: the low-shear servo piston fills gently while integrated MAP nitrogen flushing removes oxygen to preserve the signature green colour and extend shelf life.
Why the SDH-R Protects Avocado Products
Low-Shear Gentle Filling
The servo-driven piston moves at controlled speed to fill chunky guacamole without crushing avocado pieces. Adjustable stroke rate preserves product texture.
MAP Prevents Browning
Nitrogen flushing displaces oxygen in the headspace before sealing. Guacamole maintains green colour and fresh flavour for 30–45 days vs. 3–5 days without MAP.
High-Speed Retail Packaging
Package guacamole into 4oz, 8oz, 12oz, or 16oz retail cups at 30 per minute — fast enough for co-packers supplying major grocery chains.
Easy Batch Changeover
Switch between mild, spicy, chunky, smooth, or flavoured guacamole variants in under 15 minutes with PLC-stored recipe parameters.

How the SDH-R Fills Guacamole
Fully automatic process from empty cup to sealed product — no manual labour required
Cup Denesting
Empty cups are automatically separated from a nested stack and placed into the rotary table carriers. The pneumatic denester handles round, square, and rectangular cups from 2oz to 32oz — ideal for the standard guacamole cup formats your customers expect.
Servo-Driven Filling
The volumetric piston filler draws a precise dose of guacamole and dispenses it into the cup. Servo control adjusts stroke length and speed per recipe, maintaining ±0.5% fill-weight accuracy across production runs. The PLC stores recipes for quick changeovers between product variants.
Membrane Heat Sealing
Roll-stock film is drawn across the filled cup and heat-sealed to create a tamper-evident, airtight membrane. Sealing temperature, pressure, and dwell time are individually controlled to match your specific film and cup material combination.
Snap-On Lid (Optional)
A pick-and-place mechanism applies a consumer-friendly snap-on plastic lid over the membrane seal. This two-barrier system provides both tamper evidence and reclosability — the standard expected by grocery retailers and foodservice distributors.
MAP Nitrogen Flush (Optional)
Modified Atmosphere Packaging replaces oxygen in the headspace with food-grade nitrogen immediately before sealing. For guacamole, this typically extends refrigerated shelf life from 7–10 days to 30–45+ days — a requirement for most retail distribution channels.
Guacamole Cup Packaging: Controlling Oxygen, Texture and Seal Quality
Guacamole browning is enzymatic. Once avocado flesh is cut, polyphenol oxidase reacts with oxygen and the surface darkens, which means the clock starts at the cutting table, not at the sealing station. Packaging guacamole well is therefore about limiting oxygen exposure along the whole route: batch mixing, time in the hopper, the fill itself and the headspace under the film. Nitrogen MAP deals with the last of these by bringing residual oxygen down to 0.3-0.4% before the seal, but it cannot remove oxygen that was mixed into the product earlier.
A low-oxygen filling routine
- Keep batches small and refill the hopper often so product does not sit exposed.
- Fill cold, at a pumpable temperature confirmed with our engineers for your recipe.
- Use a slow, gentle piston stroke and large-bore valving on chunky styles so avocado pieces are not sheared into paste.
- Fill to a level surface with modest headspace, then nitrogen flush and seal without delay.
- Specify oxygen-barrier cups and film; MAP only holds when the packaging blocks oxygen ingress.
- Check seals at every start-up and recipe change, because a single channel leak lets air back in.
Cup formats for guacamole programs
Common guacamole cup formats on the SDH-R
| Format | Typical use | SDH-R notes |
|---|---|---|
| 2 oz portion cup | Snack packs, meal kits, quick-service sides | Low end of the 50-500 g fill range; fill weight confirmed with our engineers |
| 4 oz cup | Single-serve retail and grab-and-go | Standard size |
| 8 oz tub | Core retail SKU | Standard size |
| 16 oz tub | Family and club packs | Standard size |
| Square or rectangular tub | Differentiated shelf presence | Custom tooling for the cup shape |
Closure choice follows from the atmosphere. The heat-sealed membrane is what holds the nitrogen in, so it has to be continuous around the whole flange; a snap-on plastic lid applied after it protects the membrane in transit and lets the shopper reclose the cup once it is opened. Because guacamole is usually eaten over a day or two after opening, that reclosable lid matters more here than on single-use portion cups.
Many retail guacamole programs also use high-pressure processing (HPP) after sealing. HPP is a separate process that the SDH-R does not perform, but the machine fills and seals cups that can go on to an HPP vessel. If HPP is in your plan, choose a cup and membrane film rated for it with your HPP processor and film supplier, and tell us early so we tool for that cup.
Allergen planning matters because guacamole often shares equipment with hummus. Plain guacamole typically carries no major allergens, while hummus contains sesame and avocado-ranch styles may contain milk or egg. Run plain guacamole first and complete a validated clean before it runs again. Product-by-product handling for avocado dips and salsas is compared in our salsa, sauce and guacamole cup filling article, and flushing options are explained on the MAP cup filling machine page.

Guacamole Cup Packaging — Frequently Asked Questions
It slows browning rather than stopping it. Nitrogen MAP on the Hummus Pack SDH-R reduces residual oxygen in the cup headspace to 0.3-0.4% just before sealing, which limits the oxygen available to the browning reaction. Results also depend on how long the product was exposed before filling, how much air was mixed in, the acidity of the recipe and whether the cup and film are oxygen barriers.
Not if it is set up for chunky product. The SDH-R's servo-driven piston can run a slower, gentler stroke profile, and large-bore valving lets avocado pieces pass without being forced through a narrow opening. Very large or very soft chunks still need checking, so our engineering team reviews your chunk size and recipe before quoting and stores the agreed stroke settings as a recipe on the PLC.
The SDH-R does not perform high-pressure processing (HPP), but it fills and seals pre-formed cups that can be sent to an HPP vessel afterward. Success depends on choosing a cup and membrane film rated for HPP and validating the sealed pack with your HPP processor. Tell Hummus Pack at the quoting stage if HPP is planned so the cup tooling and film are specified accordingly.
There is no single number, because guacamole is more oxygen-sensitive than most dips. For refrigerated dips, nitrogen MAP that lowers residual oxygen to 0.3-0.4% typically extends shelf life from roughly 7-10 days to 30-45+ days, and the SDH-R offers that flush as an option. Guacamole results vary with recipe, acidity, processing and cold chain, so confirm your target with a shelf-life study before setting retail dates.
The Hummus Pack SDH-R runs 4, 8, 10 and 16 oz cups as standard and custom cups from 2 to 32 oz with matching change parts, in round, square or rectangular shapes. Its standard fill range is 50-500 g, so 2 oz portion cups for meal kits and quick-service sides sit at the low end of what it handles, and fills above 500 g fall outside the standard range.
Yes. Guacamole and hummus can share one SDH-R, with recipe changeover in under about 15 minutes. The constraint is allergens rather than mechanics: hummus contains sesame, a major US allergen since 2023, while plain guacamole usually contains none. Run guacamole first, then hummus, and complete a validated clean before guacamole runs again. Our hummus packaging guide covers the sesame side.
