Effects of various sweeteners (sucrose, maltose syrup and honey) on individual anthocyanins, colour and turbidity in sour cherry (SCN) and strawberry nectars (SN) were investigated during 168 and 42 days of storage at 20 A degrees C, respectively. In SCN, major anthocyanin was cyanidin-3-glucosylrutinoside (cyd-3-glu-rut), followed by cyanidin-3-rutinoside (cyd-3-rut), cyanidin-3-glucoside (cyd-3-glu) and cyanidin-3-sophoroside (cyd-3-soph). Maltose syrup increased stabilities of cyd-3-glu-rut (8%) and cyd-3-rut (4%), while honey reduced stabilities of all anthocyanins in SCN. Due to higher anthocyanin stability, maltose syrup for SCN was recommended. In SN, the major anthocyanin was pelargonidin-3-glucoside (pg-3-glu), followed by pelargonidin-3-rutinoside (pg-3-rut) and cyd-3-glu. Stabilities of anthocyanins (46-51%) and colour density (6-7%) in SN sweetened with honey were higher than that sweetened with sucrose and maltose syrup. Considering maximum wavelength (lambda(max)), absorbance value at lambda(max) (A(max)), polymeric colour and colour density values together, copigmentation of anthocyanins occurred in SN sweetened with honey. This study is the first study showing copigmentation of anthocyanins with honey.

Effects of natural copigment sources in combination with sweeteners on the stability of anthocyanins in sour cherry nectars Ertan, Kübra; ÖZKAN, MEHMET (2019-10-01) Effects of various co-pigment sources [gallic acid (GA), rose leaf extract (RLE), cherry stem extract (CSE), pomegranate rind extract (PRE) and green tea extract (GTE)] on anthocyanin content, colour, and turbidity in sour cherry nectar (SCN), sweetened with sucrose (SCNS), maltose syrup (SCNM) or honey (SCNH), were investigated during storage at 20 degrees C. Co-pigment sources were associated with increases in lambda(max) (up to 4.1 nm), colour density (up to 22%), and polymeric colour (up to 1.7 times). ...
Color and stability of anthocyanins in strawberry nectars containing various co-pigment sources and sweeteners Ertan, Kübra; ÖZKAN, MEHMET (2020-04-25) Effects of various co-pigment sources [gallic acid (GA) and the extracts of rose leaf (RLE), cherry stem (CSE), pomegranate rind (PRE) and sour cherry stem (SCSE)] on anthocyanins and colour in strawberry nectars (SNs), sweetened with sucrose (SNS), maltose syrup (SNM) and honey (SNH), were investigated during storage at 20 degrees C. Honey elicited the highest stabilities of anthocyanins, hyperchromic and bathochromic effects in SNs containing all co-pigment sources, except for PRE. PRE co-pigments were co...
EFFECTS OF SUCROSE POLYESTER COATING ON FRUIT-QUALITY OF APRICOTS (PRUNUS-ARMENAICA (L)) Şümnü, Servet Gülüm (Wiley, 1995-04-01) Mature apricots were coated with different concentrations of a mixture containing sucrose polyesters (Semperfresh(TM) fruit coating) to determine the effect of that coating on shelf-life, post-storage life and quality of apricots. Respiration rates, weight loss, colour change, variations in soluble solids, ascorbic acid content, titratable acidity and pH of apricots were effectively reduced by both the 10 g litre(-1) and 15 g litre(-1) concentrations during ambient storage. After 10 days of cold storage bot...
Effect of high hydrostatic pressure on microbial load and quality parameters of grape juice Mert, Mecnun; Alpas, Hami; Department of Food Engineering (2010) Effect of high hydrostatic pressure (150-200-250 MPa) on the microbial load and quality parameters (pH, color, 5-hydroxymethylfurfural-HMF) of white (Sultaniye) and red (Alicante Bouschet) grape juices with combination of temperature (20-30-40°C) and holding time (5-10-15 min) was studied. Increased pressure and temperature showed significant effect on microbial reduction in white and red grape juices (p<0.05). The effect of pressure and time on pH drop was found to be insignificant (p>0.05). HHP resulted i...
Effect of added ingredients on the acrylamide level and quality of extrudates Yavuz, Merve; Şensoy, İlkay; Özçelik, Beraat; Department of Food Engineering (2014) Ingredients which are NaCl, CaCl2, ascorbic acid, citric acid, glycine, cysteine and quercetin were blended at two different concentrations with whole wheat flour, mixed with D-glucose monohydrate (100:5, w/w), and fed to twin screw extruder. Effect of these ingredients on acrylamide level and quality characteristics of extrudates were investigated. Set zone temperatures were 80 ± 2, 90 ± 2, 115 ± 2 and 150 ± 2 oC with 180 rpm screw speed and feed flow rate of 30 g/min during extrusion. Feed moisture conten...
