چکیده

Collagen-supplemented milk products are susceptible to damage due high-temperature processing Pulsed Electric Field (PEF) pasteurization is carried out with a pretreatment temperature of <65oC maintain quality. This study aims determine the total microbe, level microbial decline and intensity sensory profile supplemented collagen by in PEF process. used completely randomized design factorial pattern 2 factors 3 replications, first factor was (30, 45 60oC), second time (10, 20, 30 minutes) which then pasteurized using method voltage 15 kv/cm for 120 seconds. Furthermore, these 9 treatments were compared without Low Temperature Long Time / LTLT (pasteurized at 65oC minutes). The results showed that 60oC 20 minutes resulted count 3.406±0.19 CFU/mL 3.395±0.146 log CFU/mL, respectively. average microbe combination smaller than process alone value below SNI standard so it safe consumption. decrease 2.88 cycles not significantly different (P<0.05) thermal pasteurization. test 10, had closest on attributes fishy aroma, taste.

Change in Color and Volatile Composition of Skim Milk Processed with Pulsed Electric Field and Microfiltration Treatments or Heat Pasteurization †

Non-thermal processing methods, such as pulsed electric field (PEF) and tangential-flow microfiltration (TFMF), are emerging processing technologies that can minimize the deleterious effects of high temperature short time (HTST) pasteurization on quality attributes of skim milk. The present study investigates the impact of PEF and TFMF, alone or in combination, on color and volatile compounds i...

Concentrated high intensity electric field ( CHIEF ) pasteurization of milk

Concentrated high intensity electric field (CHIEF) is non-thermal pasteurization technology that uses microsecond pulses of electricity to inactivate bacteria without causing undesirable changes in flavor or quality of a product. This technology was explored as an alternative to current milk pasteurization processes, and was examined for its effects on microbial stability, sensory, quality and ...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
