Carrot puree (Daucus carota subsp. sativus)
Description
• Vegetable preparation from sound, mature carrots, cooked and milled/refined to a homogeneous texture (smooth or rustic), often deaerated and heat-stabilized.
• Sweet–earthy sensory profile; orange color due to carotenoids (mainly β-carotene).
• Used as a base ingredient in baby foods, soups, sauces, bakery, beverages, and ready meals.
Caloric value (per 100 g)
• “Plain” products with no added sugars: ~30–45 kcal; carbohydrates ~7–10 g (sugars 3–5 g), fiber ~2–3 g, protein ~0.6–1.0 g, fat ~0.1–0.3 g.
• Values depend on °Brix (solids) and any dilution/additions.
Key constituents
• Carotenoids: β-carotene (provitamin A), α-carotene, lutein (stability affected by light/oxygen).
• Dietary fiber: pectins/hemicelluloses (viscosity and satiety).
• Sugars: sucrose, glucose, fructose (natural sweetness).
• Organic acids: malic, citric; typical pH ~5.2–6.2.
• Phenolics: chlorogenic acid (trace).
• Minerals: potassium dominant; small calcium/magnesium; sodium low unless added.
• Quality parameters: °Brix/TSS, color L, a, b***, viscosity (e.g., Bostwick), particle size, pH, high aw (requires adequate heat process).
Production process
• Prep: selection, washing, optional peeling; sizing/slicing.
• Blanching/cooking: enzyme inactivation, tissue softening.
• Grinding/refining: milling and sieving for uniformity (remove coarse fiber).
• Deaeration: lower dissolved O₂ to protect carotenoids.
• Stabilization: pasteurization or sterilization (retort/aseptic); optional mild acidification.
• Packaging: hot-fill or aseptic in barrier packs; full traceability under GMP/HACCP.
Sensory and technological properties
• Color/aroma: intense orange; sweet and earthy; color fades with oxidation/photolysis.
• Rheology: viscoelastic, often thixotropic; fiber builds body and limits syneresis.
• Functionality: contributes natural sweetness, structure (pectins), moisture, and color; good satiety.
Food uses
• Soups, purées, baby foods (single or blended).
• Sauces/bases for ready meals; fillings; vegetable gnocchi/doughs.
• Savory bakery (flatbreads, crackers) for color/softness; vegetable smoothies.
• Inclusion: from functional share to principal phase (≈5–40% depending on application).
Nutrition and health
• Provitamin A: β-carotene supports vitamin A needs (conversion varies by status).
• Fiber aids satiety and bowel regularity.
• Fat negligible; generally low sodium.
• Adding a small lipid phase in recipes improves carotenoid absorption.
• Suitable for low-fat and reduced-calorie formulations; age-appropriate textures for infants.
Quality and specifications (typical topics)
• °Brix/TSS, pH, viscosity within spec; total carotenoids (mg/100 g) as marker.
• Color L*, a*, b*; absence of oxidation (off-flavor/browning).
• Microbiology: pathogen-free; compliant total count; validated thermal process/shelf-life.
• Sensory: balanced sweet–earthy profile; no bitterness.
Storage and shelf-life
• Closed aseptic packs: store cool, protected from light/oxygen.
• After opening: refrigerate 0–4 °C and use within 2–3 days.
• Avoid temperature/light cycling that degrades carotenoids; apply FIFO.
Allergens and safety
• Carrot is not a major allergen; possible reactions in those sensitive to Apiaceae (cross-reactivity).
• Check for celery or other allergenic vegetables in blends/recipes.
• Hygiene per HACCP; intact, food-grade packaging.
INCI functions in cosmetics
• Typical entries: Daucus Carota Sativa (Carrot) Root Extract, Daucus Carota Sativa (Carrot) Juice, Beta-Carotene.
• Roles: antioxidant/skin conditioning, subtle color tone support (yellow–orange) in leave-ons; use extracts/juices rather than purée “as is”.
Troubleshooting
• Color fading: oxygen/light → deaerate, barrier packs, minimize exposure.
• Phase separation/syneresis: insufficient fiber or coarse grind → finer sieving, pectins/homogenization.
• Bitterness: overcooking/oxidation → gentler heat curve, suitable natural antioxidants.
• Grainy texture: under-refining → finer mesh or homogenization.
• Out-of-range pH: stability/micro risk → adjust with permitted acidulants; validate process.
Sustainability and supply chain
• Upcycling peels/tops for feed, compost, or carotenoid/fiber extracts.
• Effluent management to BOD/COD targets; heat recovery in thermal steps.
• Recyclable packaging; optimized cold logistics; GMP/HACCP across the chain.
Conclusion
Carrot purée offers natural color, sweetness, and structure with solid nutritional credentials (provitamin A, fiber). Application success depends on raw materials, refining, deaeration, thermal process, and protection from light/oxygen; with proper specs it is stable and repeatable.
Mini-glossary
• °Brix — Percentage of TSS; guides concentration and perceived sweetness.
• TSS — Total soluble solids: sugars/acids/salts; correlates with density and yield.
• pH — Acidity/alkalinity index; affects microbial stability and color.
• aw — Water activity: high in purées; necessitates adequate heat stabilization.
• Bostwick — Empirical measure of spread/flow for purées (lower = thicker).
• GMP — Good Manufacturing Practice: hygiene and process-consistency standards.
• HACCP — Hazard Analysis and Critical Control Points: preventive food-safety system with defined CCP.
• BOD/COD — Biochemical/Chemical Oxygen Demand: effluent load indicators for wastewater impact.
• FIFO — First In, First Out: stock rotation using older lots first.
Studies
Carrot is one of the major vegetables rich in bioactive compounds like carotenoids and dietary fibers with appreciable levels of several other functional components having significant health-promoting properties. Carrot pomace, containing about 50% β-carotene, can be profitably utilized for the supplementation of products like cake, bread, and biscuits.
Beyond lending truth to the old adage that carrots are good for eyes, the carotenoids, polyphenols, and vitamins present in carrots act as antioxidants, anticarcinogens, and immunoenhancers. Anti-diabetic, cholesterol and cardiovascular disease-lowering, anti-hypertensive, hepatoprotective, renoprotective, and wound healing benefits of carrots have also been reported.
Consumption of carrots is beneficial to our digestive system as an intestinal balancer because some of its compounds possess high antioxidant power (1).
It contains falcarinol, a natural component discovered only in 2005 that acts as an anti-tumor agent (2).
It also contains Beta carotene, a natural component that turns into vitamin A when it is assimilated into the human body.
Its properties are not altered if it is prepared as juice or lightly boiled or fried.
In addition to the common orange carrot, there is also the black, white, purple and yellow carrot.
