CONTROL OF ENZYMATIC BROWNING OF APPLE SLICES

Efficacy of sodium chlorite as an inhibitor of enzymatic browning in apple slices

Sodium chlorite (SC) is an effective sanitizer for inhibiting microbial growth. This investigation was conducted to determine the efficacy of SC as a browning control agent for use on fresh-cut apple slices, applied alone, or in conjunction with organic acids. Additionally, the authors compared the efficacy of SC to that of acidified sodium chlorite (ASC) and to several other salts and examined...

Studies on the Occurrence of Non-enzymatic Browning during the Storage of Cloudy Apple Juice

Abstract 120 day storage experiment at 4°C, 22°C and 40°C of cloudy apple juice without AA added or juice with 0.006% or 0.024% (w/w) AA added was conducted. The content of polyphenols, 5-(hydroxymethyl)furaldehyde (5-HMF), ascorbic acid, and the color were assessed by HPLC and other analysis techniques. The formation of new particles in juice during storage was studied by electronic scan micro...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Enzymatic browning and antioxidant activities in harvested litchi fruit as influenced by apple polyphenols.

'Guiwei' litchi fruit were treated with 5 ga.i. L(-1) apple polyphenols (APP) and then stored at 25°C to investigate the effects on pericarp browning. APP treatment effectively reduced pericarp browning and retarded the loss of red colour. APP-treated fruit exhibited higher levels of anthocyanins and cyanidin-3-rutinoside, which correlated with suppressed anthocyanase activity. APP treatment al...
