Estimation of carotenoid and vitamin A losses during industrial air drying and freeze drying


, : Estimation of carotenoid and vitamin A losses during industrial air drying and freeze drying. Arquivos de Biologia e Tecnologia 36(1): 83-94

A cultivar of spinach grown commercially in Brazil had beta -carotene 489, lutein and violaxanthin 1025, zeaxantina 182 and neoxanthin 49 ug/g. After drying in air and after freeze drying, beta -carotene decreased (P<=0.01) by about 12% but other values did not decrease and neoxanthin showed a significant (P<=0.05) increase.

Dried lucerne from 5 sites near Zaragoza, Spain, contained an average of 8.13% water, 20.99% CP, 24.59% cellulose, 40.07% NFE and 2.14% glutamic acid. The carotene content was 87-290 mg/kg and the xanthophyll content 270-610 mg/kg. During drying,...

To overcome the flaws of high energy consumption of freeze drying (FD) and the non-uniform drying of microwave freeze drying (MFD), pulse-spouted microwave vacuum drying (PSMVD) was developed. The results showed that the drying time can be dramati...

Under freeze-drying, vacuum drying and heat drying procedures, there is a considerable loss of aroma and other volatile compounds in various food components. However, the most important nutrients and vitamins undergo slight or no loss during the f...

Button mushroom slices were dehydrated using freeze drying (FD) or FD combined with microwave vacuum drying (FMVD), and the non-volatile component profiles were studied. The results showed that the level of non-volatile components in button mushro...

In this work, we explore the idea of using mathematical models to build design space for the primary drying portion of freeze-drying process. We start by defining design space for freeze-drying, followed by defining critical quality attributes and...
