Centrifugal Filter-Assisted Block Freeze Crystallization Applied to Blueberry Juice

A Centrifugal Gradocol Filter.

Details of a centrifugal Seitz filter for sterilizing small quantities of fluid were reported some months ago in this journal (Hilson and Elek, 1950). It was then considered that a similar filter, fitted with a gradocol membrane (Elford, 1931) for virus or bacteriophage work where an asbestos pad is not suitable, might be useful. Moreover, a suggestion has been made (Latner and Slack, 1950) tha...

Complementary Freeze Fracture Methods Applied to Cattle

densely in the P-face and scattered in the E-face. Like a number of preceding investigators who have failed to obtain convincing findings to correlate similar profiles with the visual pigment molecules, we should also raise a question about preparation involving chemical and thermal procedures affecting the dimensions of the final images. Our constant results obtained from the two methods, howe...

Ion Exchange Applied to Sugar Juice Purification

Purification E. A. H A A G E N S E N 1 The process for recovering sugar from sugar beets has existed in its present form substantially unchanged since its inception over 100 years ago. There have been many improvements in technique and equipment but the essential methods have remained relatively the same. Now a new process of juice purification has been developed that promises to remove most of...

Comparative study of three drying methods: freeze, hot air- assisted freeze and infrared-assisted freeze modes

The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...
