China Focus: Hard seltzer, protein powder and local dairy regulations feature in our round-up Hard seltzer, protein powder and local dairy regulations feature in this edition of China Focus. LINGYA (零呀), the company which produced China’s first locally made hard seltzer has rebranded to ZEYA, in line with a new local and regional strategic plan. Founded in June 2020, the Shanghai-company first introduced six hard seltzer products in China, which were low calorie, and contained zero sugar. They came in cucumber, blackberry, strawberry, white peach, grapefruit and passionfruit flavour variations. China-based firm ffit8 is launching probiotic protein powder to boost immunity and mood, following the success of its flagship protein bar last year.
