The effects of fermentation time, nitrite level and heat treatment on biogenic amine formation and some properties of sucuk

By admin

In order to determination the possibilities in the reduction of nitrite level
and fermentation time, the effects of fermentation time (13 days), nitrite level (45-
195 ppm) and heat treatment (30-90 ºC) on biogenic amine formation and some
physical-chemical, microbiological and sensory properties of Sucuk were
investigated by using Central Composite Design of Response Surface Methodology.
Fermentation time decreased Micrococcus-Staphylococcus [...]

Effect of nitrite contents on the formation of colour in the thermal processed sucuks

By admin

In the study the effect of different nitrite levels on color formation of heat
processed sucuk. Five different levels of sodium nitrite (0, 25, 50, 75, 100 ppm) was
added to sucuk doughs, stuffed sucuks were fermented at 23-25ºC, 0.5 m/s air velocity
and 90% relative humidity for three days. Sucuks from different nitrite levels were
divided into two [...]

Identification and classification of virulent bacteriophages of streptococcus thermophilus and Lactobacillus bulgaricus based on their replication parameters, capsid protein profiles and restriction endonuclease analysis

By admin

In this thesis, we have determined DNA restriction patterns, structural protein analysis and
replication parameters of 26 S. thermophilus (709, 231, B3) and 24 Lb. bulgaricus (Y4, V1, V2)
phages. Furthermore, sensitivities of natural and commercial S. thermophilus and Lb. bulgaricus
strains to both of B3 S. thermophilus and 231 V1, V2 Lb. bulgaricus phages have been
investigated. It [...]

Chemical, microbiological, textural and sensory properties of marinated poultry meats with different methods

By admin

In this research, tumbling process applied to broiler and turkey, breast and leg meats
as a raw material. During tumbling different concentrations of acidic and basic marinades
were applied. After tumbling process chemical, microbiological, sensory and textural changes
of marinated meats were evaluated and the positive effect of marination on end product were
determined.

Production and characterization of acid modified starch

By admin

In this study, a high amylose (amylotype) corn starch (Hylon VII) sample was acid
hydolysed with HCl at 40ºC for various periods of time (0.5, 1.0, 1.5, 2.0 hr). For resistant
starch formation native (control) and hydrolysed starch samples were subjected to 2
different heat treatments. In the first one the samples were heated in a water bath [...]

Production of a spreadable meat product from Turkey meat

By admin

Trading and production of poultry meat have increased in the last years. With
increased interest in fastfood and ready-to-eat products, a search has begun for new
meat products that will attract consumers. This study examines the parameters
required for production of a spreadable raw fermented meat product which is a new
product for Turkey and which may address the [...]

Some properties of stirred type yoghurts made from milk with adjusted fat content and added with exopolysaccharides-producing starter cultures

By admin

In this study, nine different stirred type yogurts were manufactured from cow’s
milk, in which fat content was standardized to 3, 1.5 and 0.5%, by using non
exopolysaccharide (EPS) producing (EPS-) and EPS-producing (EPS+) strains of
yoghurt bacteria. The milks, used in the manufacture were divided into three bathces
and their fat contents were standardized to 3%, 1.5% and [...]
