title: Nutritional assessment of processing effects on major and trace element content in sea buckthorn juice (Hippophaë rhamnoides L. ssp. rhamnoides).
abstract: Processing effects on the mineral content were investigated during juice production from sea buckthorn (Hippophaë rhamnoides L. ssp. rhamnoides, Elaeagnaceae) using berries from 2 different growing areas. The major and trace elements of sea buckthorn berries and juices were determined by atomic absorption spectroscopy (AAS)--(calcium, iron, magnesium, potassium, sodium) and inductively coupled plasma-mass spectrometry (ICP-MS)--(arsenic, boron, chromium, copper, manganese, molybdenum, nickel, selenium, zinc). Potassium is the most abundant major element in sea buckthorn berries and juices. The production process increased the potassium content in the juice by about 20%. Moreover, the processing of juice increased the value of manganese up to 32% compared to the content in berries. During industrial juice production, the technological steps caused a loss of about 53% to 77% of the chromium concentration, 50% of the copper content, 64% to 75% of the molybdenum amount, and up to 45% of the iron concentration in the final juice product. Consumption of sea buckthorn juice represents a beneficial source of chromium, copper, manganese, molybdenum, iron, and potassium for the achievement of the respective dietary requirements.
