HPP and TP samples were stored for

HPP and TP samples were stored for up to 12 months at two different
ambient temperature (20 °C and 28 °C) conditions and analysed after 0,
½, ¾, 1, 2, 3, 6, 9 and 12 months storage for microbial counts, colour,
phytochemicals, antioxidant activity and enzyme activity. Phytochemicals,
antioxidant activity and enzyme activity analyses were carried out
on freeze-dried samples, taken at each sampling time but processed all
at the same time (i.e., after 12 months). Freeze drying was achieved
using a freeze dryer (Christ-Alpha 1–4 LD, Germany
