 Indena grape seed extracts earn kosher certification-02-Nov-2011
Italian botanical extracts leader, Indena, has earned "LBD" kosher certification for its range of polyphenol-rich grape seed extracts from the largest kosher agency in Europe, as the market for kosher products expands. The certification took several years to achieve and included, “extensive site inspections by Rabbi Akiva Padwa”, director of certification at the UK-based kosher agency, KLBD. The review included, “the entire process from harvest, through preparation of the seeds to the extraction of the polyphenols.”
“We were delighted to go through the auditing process because KLBD is recognised by our customers as an international kosher agency,” said Christian Artaria, marketing director and head of functional food development at Indena. Certification is opening up markets and helping to make business easier.”
