In order for his children to eat fresh and delicious yogurt, Mr. Lenlight invented a unique and simple yogurt fermentation system in 1993 – the easy-to-use, unplugged yogurt fermentation system. Yijiyou is currently the world's largest DIY yogurt brand, selling well on all continents, with a market share of more than 75% in New Zealand and Australia. In 2010, Yijiyou Products was acquired by Westland (West) Dairy Company of New Zealand, and all the raw materials are high-quality whole milk powder of Westland Dairy Company, and a variety of natural fruit juices are added. Yijiyou yogurt powder is slightly expensive, and the yogurt made after fermentation is coagulated, showing different colors because of its different tastes, delicate and smooth taste, fragrant and mellow, and I feel that it is worth it when I taste it.
