Below is a comparison of two completely different methods of producing cooking oil.
The example is based on Grape seed oil.
Fresh, carefully selected raw materials.
Grape pomace is delivered to our production line within 12 hours after grape press for juice and wine production.
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
Within 6 hours grape seeds are cleaned and separated out of skin
The grape residue used in distillery or alcohol production.
Within 24 hours grape seeds are carefully dried in a temperature of max 50°C using non-direct heating
Raw material drying temperature is from 60 to 250°C.
No time restrictions
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.
Oil is extracted from seeds with chemicals such as hexane and methanol.
Allows to extract 95% of oil from seeds.
Colorless and odorless liquid. Used for formation of glues for shoes, leather products, roofing, and in the extraction of oil from seeds.
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.
The oil is bottled, and then going on capping, labeling, shrink wrapping, and the packaging of bottles in the boxes.
Fresh and tasty oil is sent to the destination.
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.
By treating with water between 85 and 95°C steam, or water with acid. Phosphatide flakes removing by centrifuge.
By filtering oil through activated carbon or activated clays
Deodorization through the vacuum with hot steam up to 250°C, to remove color, odor, and bitterness.
