Production

Below is a comparison of two completely different methods of producing cooking oil.
The example is based on Grape seed oil.

Our method

Cold-Pressed

Industrial

Refined

Fresh grape seeds
1

Receiving

Fresh, carefully selected raw materials.

Grape pomace is delivered to our production line within 12 hours after grape press for juice and wine production.

Industrial grape processing
1

Receiving

Minimum requirements for the quality of raw material

The grape residue can be kept in silo storage for several months after being taken from the winery

Grape seed separation
2

Separation

Within 6 hours grape seeds are cleaned and separated out of skin

Alcohol production
2

Alcohol production

The grape residue used in distillery or alcohol production.

3

Drying

Within 24 hours grape seeds are carefully dried in a temperature of max 50°C using non-direct heating

3

Drying

Raw material drying temperature is from 60 to 250°C.

No time restrictions

Cold pressed oil extraction
4

Oil pressing

Oil is produced by mechanical pressing method

Seeds are pressed in screw press under the temperature of maximum 50°C

Allows to get 50-70% of the oil from the seeds

No chemical additives, preservatives, colorants.

Chemical oil extraction
4

Oil extraction

Oil is extracted from seeds with chemicals such as hexane and methanol.

Allows to extract 95% of oil from seeds.

What is Hexane?

Colorless and odorless liquid. Used for formation of glues for shoes, leather products, roofing, and in the extraction of oil from seeds.

Oil filtration
5

Filtration

Oil passes through drum vacuum filter, where oil sediment remains on the filter.

Second filter cleans the oil from all micro parts and oil sediment.

Oil bottling
6

Packaging and labeling

The oil is bottled, and then going on capping, labeling, shrink wrapping, and the packaging of bottles in the boxes.

7

Shipment

Fresh and tasty oil is sent to the destination.

Oil refining
5

Refining

Heating the oil slurry in up to 85°C water and mixing with an alkaline substance. The oil is further washed to remove traces of soap and then dried.

Degumming

By treating with water between 85 and 95°C steam, or water with acid. Phosphatide flakes removing by centrifuge.

Bleaching

By filtering oil through activated carbon or activated clays

Deodorization

Deodorization through the vacuum with hot steam up to 250°C, to remove color, odor, and bitterness.
