Quality &
Process Excellence
All Sheetal Drop oils are manufactured, refined, and packed in-house by Hyderabad Refineries — from raw seed selection to automated pouch sealing. We do not outsource any stage of production.
Manufacturing Excellence & Infrastructure Capacity
We operate two state-of-the-art facilities in Hyderabad dedicated to high-tonnage oil refining, quality lab testing, and touch-free automated packaging.

Refining Workflow Stages
Every batch of Sheetal Drop oil goes through a rigorous multi-stage refining process to ensure purity, clarity, and natural nutritional integrity.
Degumming
Removes phospholipids and mucilaginous gums
Crude oil contains hydratable and non-hydratable phospholipids (gums) that make the oil cloudy and degrade heat stability. The oil is heated to 60–80°C, mixed with water and small amounts of food-grade acid (phosphoric or citric acid), and agitated. Phospholipids absorb water, swell, become insoluble, and are separated via high-speed centrifuges.
Bleaching
Removes pigments, trace metals, and oxidation compounds
Neutralized oil still contains colour pigments (like chlorophyll and carotenoids) and residual oxidation impurities. The oil is mixed with activated bleaching earth (clay) and activated carbon under a vacuum at 90–110°C. The clay adsorbs pigments and heavy metals, then passed through pressure leaf filters to yield light-coloured oil.
Dewaxing / Winterization
Removes high-melting point waxes
Essential for oils like sunflower, rice bran, corn, and cottonseed that contain natural waxes which cause cloudiness when refrigerated. The oil is cooled gradually to 5–10°C for several hours to allow waxes to crystallize. Wax crystals are removed through pressure filtration, ensuring the oil remains crystal-clear at room and cold temperatures.
Deodorization
Strips volatile odour compounds and residual FFAs
Removes volatile compounds responsible for unpleasant taste and smell, as well as residual free fatty acids. The oil is heated under high vacuum (1–3 mbar) to 230–260°C while natural vapor is injected from the bottom. This vapor strips away volatile aldehydes, ketones, and odoriferous compounds. The oil is rapidly cooled to prevent re-oxidation.
Polishing & Packaging
Final safety filtration and bottling
The refined oil passes through fine micronic polish filters (bag or sparkler filters) to achieve maximum clarity. Stored in stainless-steel holding tanks before automated filling into PET bottles, pouches, or tins — often flushed with nitrogen gas to prevent oxidation and extend shelf life.
