Effect of extrusion conditions and storage temperature on texture, colour and acidity of butter

Abstract: The effect of extruder shear rate (500, 750, 1125, 1500 and 1750/s), feed temperature (5, 7, 10, 13 and 15 °C) and storage temperature (5, 7, 10, 13 and 15 °C) on the acid value, colour (L*, a* and b*values) and texture (hardness and adhesiveness) of organic butter was examined. The optimised conditions in terms of extruder shear rate, feed temperature and storage temperature were 1345/s, 13 °C and 7 °C, respectively. At the optimised conditions; the predicted responses were determined as hardness 42.5 g/cm, w… Show more

“…Color is an important property for extruded products being a quality factor directly related to the acceptability in different foods (Wani & Kumar, 2016). According to the CIELab scale, high positive values of b* indicate an increase in yellow coloration of the products (Kashaninejad, Razavi, Mazaheri Tehrani, & Kashaninejad, 2017). This response had a high Pearson correlation with the DNP factor (r = 0.962; p < 0.001).…”

“…It has a greater amount of lecithin and it is also rich in riboflavin though poor in vitamin C and nicotinic acid (Raynal-Ljutovac et al, 2008). Significant changes may occur to butter flavour during storage as a result of lipolysis and oxidation processes (Kashaninejad et al, 2017). Lipid oxidation is undesirable in most foods due to quality deterioration that includes changes in appearance, texture, shelf life and nutritional profiles, and development of off-flavours and potentially toxic reaction products (Öztürk and Çakmakçı, 2006;Lim et al, 2015).…”

“…Это делает возможным формирование пороков микробиологического и биохимического происхождения вследствие изменений как в молочной плазме, так и в жировой фазе продукта. Эти изменения проявляются не только в органолептических показателях продукта (вкус и запах, внешний вид и цвет, наличие штаффа на поверхности, изменение вязкостных свойств продукта), но и в повышении отдельных физико-химических показателей молочной плазмы, биохимических изменениях жировой фазы, указывающих на образование продуктов первичного и вторичного окисления жира 4 [9,10]. Поэтому при комплексной оценке хранимоспособности должны совместно учитываться: микробиологическое состояние продукта, его органолептические, физико-химические, биохимические показатели, минимальные изменения которых подтверждают, что продукт в исследуемой точке контроля безопасен, сохранил свое качество, пищевую и биологическую ценность и может использоваться по своему прямому назначению.…”
