The antioxidant and antibacterial effect of rosemary, orange and lemon extracts was investigated in cooked Swedish-style meatballs. Activity in a lard system was established for all the extracts and further determination of the development of rancidity as thiobarbituric acid reactive substances consistently showed that about 50% of the rancidity can be controlled by the citrus preparations. Two...

infant formula has a fatty acid composition that meets the needs of the neonates for unsaturated fatty acids.these fatty acids are of major importance during this period of life in which the brain and retina are developing, and will therefore have an influence upon visual acuity and learning abilities. oxygen reacts readily with unsaturated fatty acids, so that every time these compounds are ha...

Our main goal in this project is to study the causes and finding solutions for both the hydrolytic and the oxidative rancidity that can be produced during condensed yoghurt production. The re pasteurization of the pasteurized milk and the addition of different types of antioxidants (ascorbic acid and propyl gallate) were used to achieve this goal. Chemical, physical, microbial and sensory tests...

Thermal processing of green coconut water (GCW) caused non-enzymic browning and development of rancidity. Effect of the addition of several combinations of ascorbic acid (AA) (0 to 100 ppm) and sodium metabisulfite (SMB) (0 to 30 ppm) on brown discolouration and rancidity of GCW during elevated thermal processing (121°C for 5 min at 15 psi) was investigated. Addition of AA and/or SMB significan...

The rancidification of walnuts was promoted by storing shelled kernels at 38°C for 4 weeks. Of six varieties tested, only 'Howard' and 'Chandler' kernels went rancid during this period. Their deterioration was preceded by the appearance of lipase (an oil digesting enzyme) in kernels and an accumulation of free fatty acids in the oil. The implications and limitations of these observations are di...
