This paper focuses on the comparative study of emulsifying properties of dried tofu-whey, dried soy-whey and their isolated proteins. Oil-in-water emulsions were prepared at equivalent protein concentration (0.1, 0.5 and 1.0 g/100 mL), using sunflower oil as lipid phase (oil mass fraction = 0.33). Tofu-whey and soy-whey were dehydrated by freeze-drying (LTW and LSW, respectively) or thermal-drying...
Four preparations of crude polysaccharides were obtained from Cedrela sinensis using four methods of extraction, and finally precipitation with ethanol. Hot-water and processes assisted by ultrasound and enzymes (Shearzyme or Viscozyme) were carried out. The yield of polysaccharide fraction extracted with the enzyme-assisted method using Shearzyme (P-EAS) was the highest at 10.53%. All crude saccharides...
The aim of this study was to evaluate the effect of cooking temperature on the in vitro starch digestibility of four varieties of rice: Basmati, Calrose, Arborio and Bomba. Total starch, resistant starch and amylose contents were determined in raw and cooked samples. The in vitro kinetics of starch hydrolysis were also determined, and the hydrolysis and glycemic indexes were estimated. Both the initial...
The impact of puffing on nutritional composition and phenolic profiles of kiwicha (Amaranthus caudatus L.) and quinoa (Chenopodium quinoa Willd.) was investigated. Popped kiwicha showed increased protein and lipid contents and lower contents of carbohydrates compared to the untreated grains. Higher lipid, ash and carbohydrates contents and a decreased protein content were observed after puffing of...
This study is oriented to the effect of the incorporation of grape skins and grape seeds (0, 5, 10, and 15% to weight of flour) obtained from a red grape on the rheological properties of wheat dough, and on qualitative parameters and sensory properties of the prepared cookies. With regarding to dough rheological parameters, addition of grape skins concluded in increased water absorption and reduced...
In this study, the effect of anthocyanin-rich popping maize flour on phenolic profile, antioxidant capacity and color of bread were investigated. Texture and sensory properties of maize mix-breads were evaluated also. Replacing 30% of wheat flour with blue- and dark-red-seeded maize flours increased the content of total phenolic compounds, ferulic and p-coumaric acids of mix-breads compared to the...
The effect of the application of salicylic acid (SA) and hydrogen peroxide (H2 O2 ) was evaluated on sensory quality traits of two commercial sweet bell pepper varieties, Fascinato and Orangela, by descriptive sensory evaluation, principal component analysis (PCA), and Multivariate Analysis of Variance (MANOVA). A sensory descriptive lexicon was established for the sweet pepper and an intensity score...
The aim of this study was to determine the extent of changes in physico-chemical and sensory properties of dry fermented sausages where pork backfat was partly replaced by flaxseed oil used as liquid (FXL), after encapsulation (FXE), and pre-emulsified with alginate (FXA) and soy protein isolate (FXI). During production and storage, similar pH values of all products were observed. FXL sausages had...
Protein digestibility may be Influenced by the presence of dietary fibre affecting the nutritional quality of a feed or food product. This study investigated the interplay between rapeseed (Brassica napus L.) protein and fibre constituents separated by industrially scalable pilot plant processing and recombined in mixed samples. Total dietary fibre (TDF) fractions were isolated from rapeseed hulls...
