TREE STRUCTURES OF LINEAR THRESHOLD UNITS FOR THE CLASSIFICATION OF NUMERIC EXAMPLES

A decision tree-based system for learning from numeric data is described. Results from linear algebra (pseudoinverse matrices) help the system to generate decision trees where the nodes are represented by linear threshold units minimizing the mean square error. The system's capability to provide good classifications with small decision trees is demonstrated on artificial and benchmark data.     

The effect of coagulant type on yield and sensory properties of semihard cheese from laboratory‐, pilot‐ and commercial‐scale productions

Using calf rennet or a commercial microbial rennet substitute derived from Rhizomucor miehei cheesemaking experiments were performed at laboratory and pilot scale, and at commercial scale in two industrial dairy plants during regular production. At all levels of scale, the solids transfer from milk to curd was significantly higher (0.50–1.19%) when using calf rennet. There were significant differences in levels of proteolysis during maturation and in levels of bitterness at 12 weeks of ripening between Gouda cheeses produced with calf rennet or with commercial rennet substitute at pilot and at commercial scale.     

THE USE OF SORGHUM (SORGHUM BICOLOR L. MOENCH) DHURRINASE-ENRICHED PREPARATION IN THE DETERMINATION OF TOTAL CYANIDE IN SORGHUM AND SORGHUM PRODUCTS

A dhurrinase (sorghum β-glucosidase II) which catalyzes the hydrolysis of dhurrin (p-hydroxy-L-mandelonitrile β-D-glucoside) was purified 87-fold from sorghum seeds using acetone precipitation, bentonite adsorption and column chromatography on hydroxyapatite and DEAE-cellulose. Dhurrin, the natural substrate for this β-glucosidase, was used for enzyme assay. Dhurrinase, as opposed to alkali hydrolysis of dhurrin for cyanide assay, proved to be more efficient in releasing free assayable cyanide (CN^-) during the determination of total cyanide in sorghum and sorghum-derived products.

Recent advances in milk clotting enzymes

Coagulating enzymes are an absolute necessity for the production of ripened cheese varieties. The objective of this review is to summarise and interpret the latest findings for the most important types of enzymes, which are animal rennet, genetically engineered chymosin, coagulants of microbial origin, and plant‐derived clotting enzymes. Special emphasis has been placed on aspects of enzyme chemistry and technology, selected methods for the analysis of coagulants, and the impact of the enzymes on proteolysis, cheese yield and cheese quality.
