Some new companies that focus on plant protein are starting to do business in Hong Kong. They aim to enter the mainland’s successful multi-billion-dollar food market. Impossible Foods, JUST and Beyond Meat say their products are more sustainable and environmentally friendly than animal meat. Plant proteins are fake meat products made from vegetables and grains. They include eggless eggs, pea-stuffed burgers and cell-grown fish products. The research firm Market and Markets says the value of the global meat substitutes market was around $4.6 billion last year and is predicted to reach $6.4 billion by 2023. Asia is the fastest growing part of that market. Plant protein firms have financial support from some of the world’s top billionaires, including Hong Kong businessman Li Ka-shing, philanthropist Bill Gates and actor Leonardo DiCaprio.
