HG-Pcaps® boast exceptional oxygen barrier properties, outperforming HPMC capsules by 250 times and gelatin capsules by nine times. Their outstanding stability ensures an extended shelf life; as pullulan capsules are chemically inert, they avoid cross-linking with encapsulated materials. This makes them particularly effective in safeguarding sensitive nutraceuticals such as plant extracts, antioxidants, and pharmaceutical active ingredients. Consequently, HG-Pcaps® guarantee superior protection for encapsulated substances, significantly enhancing the longevity of the capsules.
