Abstract/OtherAbstract:
|
The primary vitamin in sea buckthorn berries is vitamin C containing values of approximately 400 mg/100 g. Processing effects were investigated during juice and concentrate production from sea buckthorn berries (Hippophaë rhamnoides) and storage stability of juices was determined for up to 7 d using berries and juices from 2 different growing areas. During industrial juice production the technological processing of the berries caused a loss of about 5% to 11% total ascorbic acid (TAA) in the generated juice. The production of the concentrated juice resulted in 50% depletion of TAA. Sea buckthorn berries and juice were stored at 6, 25, and 40 degrees C for up to 7 d to investigate the temperature effects on TAA during storage. Analysis of kinetic data suggested that the degradation follows a 1st-order model. The results of the experiments showed that storage of sea buckthorn juices for 7 d at cold temperature (6 degrees C) already resulted in a degradation of TAA of about 11% to 12%. |
