Why the Purity of Lamp Oil Matters in Your Puja Room

Paraffin-based lamp oils release PM2.5 particulates, benzene, and toluene when burned in enclosed spaces — levels that can exceed safe indoor air quality thresholds with just minutes of burning. We explore the sattvic case for pure vegetable-oil lamps, what the Charaka Samhita says about sacred flame, and the combustion chemistry behind why ancient texts prescribed sesame and groundnut oil — not paraffin.

Oil Pulling with Cold-Pressed Sesame Oil: What Science and Ayurveda Agree On

The ancient Kavala Graha practice of oil pulling has surprising modern research backing it. The specific antioxidant profile of cold-pressed sesame oil — sesamol, sesamin, sesamolin — is central to why the Ayurvedic prescription specifies this oil, and not others.

MCTs vs. LCTs: Why Coconut Oil's Saturated Fats Behave Differently in the Body

The saturated fats in coconut oil are not the same as those in meat and dairy. Medium-chain triglycerides are metabolised directly by the liver as energy — not stored as fat. We explain the science behind this distinction.

Smoke Point: The Most Misunderstood Number in Cooking

Most home cooks have been told that a higher smoke point always means a healthier, more stable oil. This is partially true but significantly oversimplified. The total polar compound content, the refining level, and the antioxidant profile all matter more than the single smoke point number.

Quick Reference

Oil 101 — Everything You Need to Know at a Glance

Quick-reference cards for the most common questions about cooking with cold-pressed oils. No jargon, no filler — just the facts.

Smoke Point Guide

At what temperature each Bharat Oil begins to smoke — and what cooking methods that suits.

OilSmoke PointBest For
🥜 Groundnut~180°CDeep frying, high-heat
🌼 Mustard~160°CTempering, frying (after smoking)
🥥 Coconut~175°CSautéing, medium heat
✨ Sesame~160°CLow heat, finishing drizzle

Note: Cold-pressed oils have slightly lower smoke points than refined — but their antioxidant content makes them more heat-stable at those temperatures than their smoke point alone suggests.

Fatty Acid Profiles

The fat composition that determines nutritional character, flavour, and heat stability.

OilMUFAPUFASaturated
🥜 Groundnut46%32%17%
🌼 Mustard60%21%12%
🥥 Coconut6%2%92%
✨ Sesame40%42%14%

MUFA = monounsaturated (heart-protective). PUFA = polyunsaturated (essential fatty acids). Coconut oil's saturated fats are primarily MCTs — metabolised differently to animal saturated fats.

Oil Substitution Guide

What to use when a recipe calls for an oil you don't have — and what the trade-off is.

Refined vegetable oil → → Groundnut Oil Direct swap. Same heat stability, better flavour, better nutrition.
Olive oil (cooking) → → Groundnut Oil Better heat stability. More neutral flavour for Indian cooking.
Toasted sesame oil → → Sesame Oil Cold-pressed sesame oil has deeper flavour. Use slightly less.
Refined coconut oil → → Coconut Oil Same cooking properties. Cold-pressed version retains coconut aroma.

Purity Checklist

How to verify that an oil is genuinely cold-pressed and unadulterated — before you buy it and after.

✓
Natural sediment at the bottom — fine particles settle in cold-pressed oil. This is a good sign, not a defect.
✓
Distinctive natural smell — mustard oil should be pungent, sesame should be aromatic, coconut should smell coconut-y.
✓
Cloudiness in cold weather — groundnut and coconut oil will cloud or solidify below certain temperatures. This is natural and reversible.
✗
Perfectly clear and odourless — if an oil has no smell and perfect clarity, it has been refined and deodorised. Not cold-pressed.
✗
Labels saying "natural flavour added" — genuine cold-pressed oil needs no added flavour. This phrase signals deodorised oil with synthetic aroma re-added.
