Comparative studies in the postharvest responses of different medicinal and culinary herbs.

Freshly harvested medicinal and culinary herbs, especially flowering herbs, have an extremely high respiration rate of 300-1000 W/t at 10 deg C (3-30 times higher than for other crops). Otherwise, respiration is closely related to temperature and also persists during the postharvest period. Physiological changes during the postharvest period were examined in 9 species (including Majorana hortensis [Origanum majorana], Matricaria recutita [Chamomilla recutita], Melissa officinalis, Thymus vulgaris and Mentha piperita). The effects of the high respiration rates on product temperature, decomposition of organic matter, transpiration losses, reduction in external quality traits and decline in active constituents are described. The deposition of essential oils in glandular cells and oleosomes renders them relatively stable, but some changes were observed for some components.
