About OS (Oily Seasoning)
In Chinese cooking, oil is used to fry aromatic vegetables such as spring onions, ginger and garlic, while in Italian and other cuisines, olive oil has been used to soak various herbs and olive oil fried with garlic to add flavour and 'umami' to dishes.
Such oils are called OS (Oily Seasoning) to enable natural and authentic taste by using oils with extracted taste and flavours of the ingredients.

Characteristics of OTA OIL OS
Only uses carefully selected ingredients, enabling the natural flavouring of the ingredients.
- Our commitment
Carefully selected ingredients are only used, which enables natural flavouring of the ingredients. - Adds flavour and taste
Ingredient components are dissolved and can add not only flavour but also depth and richness of flavour. - Replicates 'authenticity'
Cooking techniques were utilised in the manufacturing process to impart an 'authentic' cooked feeling. - Excellent heat tolerance
Our unique manufacturing process maintains flavour stability.

Flavourant
Heating tends to lessen the aroma, making it more difficult to time to use flavourings effectively. It is difficult to perceive depth of flavour and it can easily become monotonous.
OS
Easy to cook, retains flavour and taste even when stir-fried or microwaved. The taste of professional chefs can be reproduced by adding OS.
