“…The applicant also provided the specification of the taxifolin extract used by Shkarenkov et al. (), who carried out a number of the toxicological studies cited in the application. This extract contained comparable amounts of taxifolin and other identified flavonoids to the applicant's product.…”

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to carry out the additional assessment for taxifolin-rich extract from Dahurian Larch as a food ingredient in the context of Regulation (EC) No 258/97. The novel food (NF) is a taxifolin-rich water-ethanol extract from the wood of the Dahurian Larch and contains a minimum of 90% taxifolin. The Panel considers that the taxifolin-rich extract is sufficiently characterised and that its compositional data and specifications do not raise safety concerns. The NF is intended to be added to non-alcoholic beverages, to yogurt and to chocolate confectionery. The Panel considers that the data on genotoxicity do not raise concern. In a subchronic rat study performed in accordance with OECD standards, the highest dose tested (i.e. 1,500 mg/kg bw) was considered to be the NOAEL. The margin of exposure (MOE) of the combined intake (158 mg) from the intended food uses (including 100 mg from food supplements) would result to about 660 for an adult weighing 70 kg. For adolescents, taking into account a default body weight of 45 kg, the MOE of the combined intake (146 mg) would be about 460. In the absence of a high percentile intake estimate for children between 9 and 14 years of age, the Panel considers the P97.5 intake estimate from the intended food uses (except from food supplements) for children between 10 and 17 years, i.e. 46 mg/day. Taking into account a default body weight of 29.4 kg (P5 body weight for children aged 10-14 years as suggested by EFSA Scientific Committee (2012)), the resulting MOE would be about 960.

“…The toxicity of a taxifolin‐rich extract from larch was assessed following single intragastric administration to rats and mice in doses up to 12,000 mg/kg bw (Shkarenkov et al., ). Intragastric administration of a single dose of 12,000 mg/kg bw resulted in no animal deaths.…”
