چکیده

Carrot slices were subjected to one of the following experiments prior to deep-frying: (A) dehydration/rehydration, (B) soaking in different antioxidants, and (C) fermentation with/without blanching. There were no significant differences (P > or = 0.05) in carotenoid contents among carrot chips treated with/without dehydration. Soaking in sodium metabisulfite resulted in the highest carotenoid content and lightness (L), redness (a), and yellowness (b) values among the antioxidant treatments. Fermentation without blanching significantly decreased (P < 0.05) carotenoid content, vitamin A activity, and fat content. Dehydration and fermentation with blanching significantly increased (P < 0.05) the lightness (L), redness (a), and yellowness (b) values of the chips. Dehydration/rehydration, but not antioxidant and fermentation, significantly decreased (P < 0.05) the water activity of the chips. The textural values of carrot chips prepared using sodium metabisulfite, without dehydration and without fermentation, were the lowest among other treatments which suggests the crispiest. Carrot chips prepared using sodium metabisulfite, without dehydration and without fermentation, had the highest carotenoid content and retention, and the highest overall acceptability score.

Effect of active edible coating made by quince seed mucilage and green tea extract on quality of fried shrimps: physicochemical and sensory properties

In the study, we were investigated effect of bioactive coating composed of quince seed mucilage (QSM) incorporating green tea extract(GTE) on oil and water content, lipid oxidation, texture, color and sensory evolution of shrimp after deep-fat frying. For this purpose, different concentration of GTE (0-20%) was blended to obtain five coating solutions (QG 0-4). We observed a significant effect ...

Effect of Pre-treatments and Drying Methods on Dehydration and Rehydration Characteristics of Carrot

The study was conducted to evaluate the effect of pre-treatments (0.1%KMS, 0.2%KMS, 0.3%KMS and blanching) and drying methods (mechanical drying and solar drying) on the dehydration and rehydration characteristics of carrot. The two drying methods yielded dehydrated products with different dehydration ratio, rehydration ratio, co-efficient of reconstitution and moisture content in both the dehy...

Production of Fish Chips from Sand Smelt (Atherina boyeri, RISSO 1810) and Determination of Some Quality Changes

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying  process resulted in a decrease in all fatty acid c...
