Jalapeno peppers (Capsicum annuum L., family Solanaceae)
(when smoked/dried: “chipotle”)

Mexican cultivar with moderate heat (~2,500–8,000 SHU), typically green when unripe, turning red at full maturity; conical/cylindrical fruit with thick, crisp walls.
Sensory profile: green/herbaceous, lightly fruity; clean, persistent pungency concentrated in the placenta/seeds; smoky notes when roasted.

Note: Jalapeño is a cultivar of Capsicum annuum characterized by fleshy fruits of medium pungency, usually harvested green but also consumed red at full maturity.
Cultivation and growing conditions of jalapeño chili pepper
Climate:
Prefers warm, temperate climates.
Sensitive to cold and frost, especially at germination and transplant stages.
Usually grown as a spring–summer crop in temperate regions.
Exposure:
Requires full sun for good plant and fruit development.
Excess shade reduces yield, pungency and color.
Soil:
Prefers fertile, well-drained, medium-textured soils.
Grows best at slightly acidic to neutral pH.
Does not tolerate waterlogging, which favors root rot and fungal diseases.
Watering:
Needs regular irrigation, keeping the soil moist but not saturated.
Water stress (alternating drought and excess water) can cause flower drop and fruit cracking.
Temperature:
Optimal seed germination when soil temperature is around 20–25 °C.
Optimal vegetative growth and fruit development between 20 and 30 °C.
Temperatures below about 12–14 °C slow growth significantly.
Fertilization:
Requires a good supply of organic matter (compost or well-rotted manure applied before planting).
Phosphorus and potassium are important to support flowering, fruit set and fruit quality.
Nitrogen should be applied moderately to avoid excessive vegetative growth at the expense of fruiting.
Crop management:
Weed control is important, especially in early growth stages.
In intensive cultivation, light mulching helps conserve moisture and limit weed growth.
In some systems, light pruning or pinching is used to promote branching and more uniform production.
Harvest:
Jalapeño fruits are typically harvested at the glossy green stage, when they reach typical size but before turning red.
They can be left on the plant to ripen fully to red for higher pungency and a more intense aroma.
Propagation:
By seed, usually in protected seedbeds or trays, followed by transplanting to open field or pots once temperatures are reliably mild.
Caloric value (per 100 g)
Fresh: ~25–35 kcal; carbs ~6 g, sugars ~3–4 g, fiber ~2–3 g, protein ~1 g, fat ~0.3–0.5 g; sodium naturally low.
Dried/powder: ~250–320 kcal, due to solids concentration.
Key constituents
Capsaicinoids (mainly capsaicin and dihydrocapsaicin) at medium levels.
Vitamin C high when fresh; provitamin A (carotenoids) higher in red fruits; chlorophylls in green fruits (prone to pheophytinization with heat).
Carotenoids (capsanthin/capsorubin in red stage), minor polyphenols, potassium.
Analytical markers: SHU (Scoville), capsaicinoids by HPLC, color (CIE L*a*b* or ASTA for powders), moisture/aw for dried goods.
Production process
Fresh: harvest green or red → sorting/grading → pack MAP or ventilated bulk.
Roasted/grilled: char skin → peel → remove placenta/seeds.
Pickled (rings/strips): cut, optional blanch, acidify (vinegar/lime) with target pH ≤4.1, add salt/spices, pasteurize and hot-fill; for shelf-stable, meet commercial sterility.
Dried/powder: low-temperature drying (or smoking → chipotle), milling/sieving → barrier packing.
Operate under GMP/HACCP with CCP on pH, time–temperature, and foreign bodies.
Sensory and technological properties
Heat can be tuned by removing placenta/seeds; acids/fats soften perceived burn; dairy buffers further.
Crisp texture of fresh fruit suits toppings; in pickles, CaCl₂ and gentle heat help retain crunch.
Color is light/oxygen sensitive; roasting develops Maillard/smoky notes.
Food uses
Salsas (pico de gallo, roja/verde), tacos/burritos/quesadillas, nachos, eggs, grilled meats/fish, marinades, and pickles (jalapeños en escabeche).
Typical dosages: fresh minced to taste; powder 0.1–0.5% in dry blends; pickles 5–20% in compound sauces (confirm via pilot trials).
Nutrition and health
Low caloric contribution at culinary portions; vitamin C is heat-labile—prefer raw or brief cooking.
Capsaicin may irritate sensitive skin/mucosa.
For pickled products, monitor sodium. Avoid unauthorized health claims.
Lipid profile
Total fat negligible; only trace SFA, MUFA, PUFA—no meaningful nutritional impact at use levels.
Health note: diets relatively higher in MUFA/PUFA than SFA are generally favorable/neutral for blood lipids; effect here is not material.
Quality and specifications (typical topics)
Fresh: size, turgor, uniform color, absence of defects (sunscald, molds), residues within limits.
Pickled: pH (3.2–4.1), declared salt, texture (crispness), drained weight, commercial sterility.
Dried/powder: moisture ≤10–12%, aw ≤0.60–0.65, ASTA color, capsaicinoids by HPLC, freedom from pests/foreign matter; mycotoxins monitored.
Storage and shelf-life
Fresh: 4–7 °C, high RH; use within 7–10 days.
Shelf-stable pickles: cool/dry/dark, 12–24 months unopened; after opening refrigerate and use in 5–7 days.
Powder/dried: cool/dry/dark in barrier packs; 12–24 months; reseal to limit oxidation. Apply FIFO.
Allergens and safety
Capsicum is not a major EU allergen, though individual cross-reactivity can occur.
Capsaicin is irritant: use PPE in production; label heat level; prevent cross-contact with other allergens in seasoning lines.
INCI functions in cosmetics
Listings: Capsicum Annuum Fruit Extract / Capsicum Annuum (Pepper) Extract.
Roles: rubefacient/warming, fragrance; manage formula pH and concentration due to irritancy risk.
Troubleshooting
Soft pickles: overprocessing or high pH → add CaCl₂, optimize hot-fill and acidity; select firm fruit.
Inconsistent heat: assay capsaicinoids and standardize chile blend; remove placenta/seeds to reduce.
Raw-green bitterness: roast/toast briefly; balance with acid (lime/vinegar) and salt.
Color fade: limit light/oxygen; use amber/barrier packs; add some jalapeño late in cooking.
Sustainability and supply chain
Favor IPM cultivation and efficient water use; valorize cores/seeds for seed oil or feed.
In-plant: treat effluents to BOD/COD targets; optimize thermal energy; use recyclable packs; full traceability under GMP/HACCP.
Conclusion
Jalapeño offers versatility, crunch, and moderate heat, suitable fresh, pickled, or roasted. Tight control of pH/time–temperature, pungency standardization, and protection from light/oxygen ensures safe, stable, and sensory-consistent products.
