Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on Yarrowia lipolytica yeast biomass as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is the dried and heat‐killed biomass of Yarrowia lipolytica, a yeast species that is widespread in nature and which can be found in the environment as well as in foods. The production process is sufficiently described and does not raise safety concerns. The information provided on the composition of the NF is sufficient and does not raise safety concerns. The applicant proposed to use the NF as a food supplement in the form of capsules, tablets or powder. The target population for the NF is the general population above 3 years of age. The maximum proposed daily use levels are 3 g/day for children from 3 years to less than 10 years of age and 6 g/day thereafter. Taking into account the composition of the NF and the proposed use levels, the consumption of the NF is not nutritionally disadvantageous. No relevant toxicological information was provided. The Panel considers that given the qualified presumption of safety (QPS) status for production purposes of Yarrowia lipolytica and the fact that the production process of the NF does not raise safety concerns, no toxicological studies are needed for the safety assessment of the NF. The Panel concludes that the NF, Yarrowia lipolytica yeast biomass, is safe under the proposed conditions of use.
