Plant protein fermented food and preparation method thereof

The invention relates to the field of fermented food, in particular to a plant protein fermented food and a preparation method thereof. Probiotics are added to raw materials, and the raw materials areused as carbon and nitrogen sources for probiotic fermentation, the fermentation products are vegetable protein fermented foods. The raw materials are coconuts or coconuts and ingredients, and the ingredients are one or more of nuts, vegetables and fruits. According to the preparation method, additional carbon sources are no longer added, and one or more strains of lactobacillus bulgaricus, streptococcus thermophilus and lactobacillus acidophilus, Bifidobacterium animalis, bifidobacterium lactis, bifidobacterium breve, bifidobacterium longum and plant bifidobacterium are used, so that the probiotics make full use and absorb the carbon sources in the raw materials, a large number of fermentation metabolites are produced, and the viable bacteria number and acid degree of the fermentation products is controlled, and
