Batch hydrolysis of olive oil was performed by Candida rugosa lipase immobilized on Amberlite IRC-50 and Al2O3. These two supports were selected out of 16 carriers: inorganic materials (sand, silica gel, infusorial earth, Al2O3), inorganic salts (CaCO3, CaSO4), ion-exchange resins (Amberlite IRC-50 and IR-4B, Dowex 2X8), a natural resin (colophony), a natural biopolymer (sodium alginate), synth...

In this study, TiO2-10%wt. carbon nanotube (CNT) nanocomposite powders were synthesized by sol-gel method at various hydrolysis rate affected by different reaction agents of acetyl acetone and benzyl alcohol. Crystallization of TiO2 was then achieved through calcination at 400 °C. The properties of nanocomposite powder investigated by scanning electron microscopy, X-ray diffraction and diffuse ...

In many areas of food processing it is desirable to reduce the length of protein molecules. The two most commonly used methods employ either inorganic acids or proteolytic enzymes to cleave peptide bonds between adjacent amino acids. Proteolytic enzymes can reduce the viscosity of aqueous protein mixtures as well as the volume of insolubles. In the Alaskan seafood industry, liquification of pro...

Specific hydrolysis of the separate groups of steroid conjugates appeared to offer the simplest technique for achieving the hydrolysis without chemical modification of the steroids (3-5). A partial solution to this problem was offered when it was found that steroid glucuronides could be hydrolyzed specifically by the use of /3-glucuronidase concentrates of either animal (Cohen (3)) or bacterial...

Sheep´s milk whey is an important source of protein and present functional properties. Studies related to the concentration sheep´s proteins are still scarce in literature. In order improve not only chemical, physical properties foods, but also absorption characteristics proteins, without impairing nutritional value, enzymatic hydrolysis process can be used. From generated bioactive peptides th...

Hypoallergenic formulas containing hydrolyzed protein are intended for use by infants to prevent cow’s milk allergy. The degree of hydrolysis epitopic areas determines the residual allergenicity whey hydrolysates (WPHs). However, only amino-acid-based infant (IFs) considered entirely nonallergenic. aim this study was investigate four commercially available WPHs with different (H1–H4) potential ...
