... composition, antioxidant potential and key quality parameters. Design/methodology/approach Using high-performance liquid chromatography and spectrophotometric methods, 12 polyphenolic compounds were identified and quantified, with antioxidant activity evaluated through 2,2-diphenyl-1-picrylhydrazyl (DPPH...

... and antioxidant activity assays as well as the HPLC-PDA system on the first day of preparation. Moreover, the effect of three days of storage on individual phenolic compounds was evaluated. Findings Kefir samples exhibited the highest total anthocyanin content levels among prepared products (255±4-702±65 µmol...

... the highest antioxidant activity. The developed formulations remained stable with minimum changes in quality and sensory attribute during refrigerated storage for 10 days. Originality/value This study suggests that addition of fruit and vegetable improve the viscosity and sensory perception of the product...

... and antioxidant activity, whereas decreased the Hauser ratio and Carr index values, hygroscopicity and solubility of enriched honey powder samples. The honey powder samples had passable and poor flow properties and very hygroscopic (>20%) structure because of the high sugar content. The phenolic and flavonoid...

... florets paste at four different levels (0, 5, 10 and 15%), with Lactobacillus casei NRRL B-1922 as a probiotic strain, to evaluate its physicochemical, phenols, antioxidant activity, minerals, vitamins, textural, microbiological and sensory characteristics during storage for 15 days. Findings...

... such as colour, pH and water activity (a_w) were performed using various instrumental techniques. Antioxidant activity of all macaron shell formulations was accessed using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH-RSA). Sensory evaluation was repeated using a five-point...

Sample III displayed the highest antioxidant activity, PPO inhibitory activity, copper reducing power and copper chelating activity, so...

... as maintaining its colour and crispness. Design/methodology/approach The water content, water activity, hygroscopicity, crispness, colour, vitamin C, β-carotene, total phenolic compounds and antioxidant activity were characterised both when the orange snack was newly obtained and after one, two...

... supplemented with 5 per cent and 1 per cent roselle flower extract, respectively. Antioxidant activity was highest in DPSB supplemented with the 5 per cent roselle flower extract and lowest in unfortified DPSB. Boron, molybdenum and zinc contents were highest in unfortified DPSB. All sensory attributes were...
