ice cream mulberry pekmez grape pekmez
2014/2/27
The effecs of pekmez concentrates (0, 2.5, 5.0, 7.5 and 10.0%) on the physical, chemical, and sensory properties of ice cream samples were examined. The addition of pekmez to ice cream formula positiv...
Analysis of Ice Structure Formed in Frozen Agar Gel
unidirectional freezing ice crystal structure dendrite diffusion of water
2009/6/18
Ice crystal structure was analyzed for frozen agar gel under unidirectional freezing in various operating conditions to elucidate the mechanism of the process of ice crystal growth. A linear relations...
Analysis and Control of Ice Crystal Structure in Frozen Food and Their Application to Food Processing
ice fraction effective thermal conductivity pressure-shift freezing
2009/6/18
The large differences in thermal properties between water and ice cause thermal properties of frozen food to be strongly dependent on ice fraction, which is a function of solute concentration and temp...
Ice Recrystallization in Sucrose Solutions Stored in a Temperature Range of -21°C to -50°C
recrystallization ice crystal cryo-SEM
2009/6/10
The recrystallization of ice crystals in sucrose solution was investigated by cryo-SEM in a temperature range of -21°C to -50°C, including temperatures around Tg′. By using the technique of image anal...
Limiting Partition Coefficient in a Tubular Ice System for Progressive Freeze-concentration
progressive freeze concentration scale-up, tubular ice system limiting partition coefficient
2009/5/8
A tubular ice system is effective for the scale-up of progressive freeze-concentration. The effective partition coefficient, K, as an index for the effectiveness of progressive freeze-concentration, i...
The aim of this research was to determine changes in sensorial properties of ice tea (peach and pear flavoured) filled in polyethylene terephtalate bottles (PET) and tin cans. Bottles and cans were st...
Application of Whey Protein Isolate Glycated with Rare Sugars to Ice Cream
rare sugars WPI glycation
2010/2/3
Glycated whey protein isolate (WPI) was prepared by incubation of WPI with the rare sugars, d-allose (All) and d-psicose (Psi) under controlled conditions. Its emulsion and foaming properties, and its...
In this study, the use of cola extract and cola flavor in ice cream production were investigated. Cola extract was used at rates of between 0 and 1.5% based on mix weight. The samples with Na2CO3 (bet...
