Enhancing flavor with health and nutrition!

Great Day is dedicated to understanding the cooking needs of Taiwanese families. In the 1980s, most households used non-plant-based oils. To provide a healthier alternative with diverse nutritional benefits, we introduced Taiwan’s first plant-based cooking oil, Great Day 100% Pure Sunflower Oil, in 1988, aiming to promote a balanced diet through a variety of cooking oils for more families.

As Taiwan's economy grew, the proportion of working women increased year by year. In 2021, we launched a shelf-stable instant meal series, offering convenient cooking solutions that help busy women prepare meals quickly and effortlessly, supporting them in pursuing their dreams.

Great Day encourages families to cook and dine together, sharing precious moments around the table, ensuring that every family enjoys both delicious and convenient meals with balanced nutrition.
