Product overview
A biscuit with product, packaging and story aligned
ΦSALIAS is positioned not only as a bakery product, but as an integrated concept where taste, natural formulation, responsible design and smart packaging communication support the same promise.
Smart
The packaging includes a bio-based experimental colorimetric label based on red cabbage anthocyanins, visible through the transparent pouch and supported by QR-code explanation.
Artisanal
The product is designed as a crispy handmade-style square biscuit with visible cereal texture, balanced sweet-sour notes and a clean-label-oriented formulation.
Ingredients
Built around physalis, balanced by cereals and warm aromatics
The selected formulation uses 18% physalis powder together with oat flakes, whole wheat flour, butter, egg, vanilla and tonka to create a crisp and memorable sensory profile.
Physalis powder
Provides the natural golden-orange color, fruity aroma, mild acidity and key value-added identity of ΦSALIAS.
Oat flakes
Bring cereal notes, visible texture and a more rustic artisanal appearance.
Whole wheat flour
Supports the cereal matrix, shaping stability and natural positioning of the biscuit.
Butter & egg
Contribute tenderness, crispiness, mouthfeel, binding and the final baked structure.
Vanilla
Softens the slightly acidic physalis notes and makes the flavor more familiar and approachable.
Tonka
Adds a refined premium aromatic note used in controlled low quantity for a gourmet finish.
Validation
Selected, tested and characterized
The 18% physalis powder formulation was selected after sensory comparison because it offered the best balance between identity, taste, texture and overall acceptability.

Smart Label — Color Guide
How to read the leaf label
The leaf-shaped label inside every ΦSALIAS pack is made from red cabbage extract. Its anthocyanins shift color depending on the pH of the package environment — each shade tells a different story.
Pink / reddish
pH < 5 — Acidic
Anthocyanins responding to an acidic environment — may indicate higher CO₂ or acidic volatile compounds in the pack.
Violet / purple
pH ≈ 6–7 — Neutral
The reference color of the fresh extract. A violet label means the package microenvironment is close to neutral.
Blue / greenish
pH ≈ 8–9 — Slightly alkaline
A visible shift toward blue or green-blue — anthocyanins reacting to a more alkaline environment inside the pouch.
Green / yellowish
pH > 10 — Strongly alkaline
A deeper structural transformation of the anthocyanin molecule in response to a strongly alkaline pack environment.
Note: The leaf label is an experimental visual indicator — not a freshness guarantee and not a safety decision. It is not edible, has no direct contact with the biscuits and does not replace laboratory analyses or shelf-life validation.
Safety & allergens
Clear handling logic for a controlled prototype
ΦSALIAS is presented as a safe and controlled food prototype when raw material control, correct baking, hygienic handling, cooling and label separation are properly managed.
Main allergens
The product contains gluten, milk and egg, and may contain traces of nuts or soy depending on the production environment.
Critical control point
Baking is the main critical control point because it contributes to product safety, moisture reduction and texture stabilization.
Packaging control point
The colorimetric label must remain visibly separated from the biscuits to prevent direct contact and consumer misunderstanding.
Visual identity
The world of ΦSALIAS
Warm honey tones, botanical forms and transparent presentation build the premium visual character of the product.
