Analyses of red pepper extracts which had been pretreated with lipase type VII (EC 3.1.1.3.) from Candida rugosa showed for the first time pepper carotenoid esters to be substrates of this enzyme. However, the extent of enzymatic hydrolysis depends on the respective carotenoid and was not quantitative compared to chemical saponification. After enzymatic cleavage, 67-89% of total capsanthin, 61-...
The objective of this study is to investigate the effects of irradiation from light-emitting diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitted from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total flavonoids and several ...
Spices are essential for adding color, fl avor and variety to our daily meals. In particular, red hot peppers (C. annuum, C. frutescence, C. chinense, C. pubescens and C. baccatum) have greatly contributed to our diet along with black pepper . Red hot pepper is rich in vitamin C, provitamin A, and B vitamins. The pungent principle of red hot pepper, capsaicin (8-methyl-N-vanillyl-6-nonenamide) ...
Blossom-end rot (BER) is one of the physiological disorders related to calcium (Ca) deficiency in the fruit which reduces yield and fruit quality of bell pepper (Capsicum annuum L.). Every year, occurrence of BER in bell pepper of Shahreza greenhouses causes a loss to farmers of this vegetable. This experiment was conducted to elucidate the effects of foliar application of calcium sources and r...
Aquaponics is one of the recirculating aquaculture systems in which plant grows without soil. Considering the lack of information about aquaponic culture for main crops like pepper and the absence of comparison of plant conditions in soilless culture, in this experiment eco-physiological characteristics of pepper in hydroponics and aquaponics were investigated. After starting the plants to flow...
BACKGROUND AND AIMS Pepper (Capsicum annuum, Solanaceae) fruits are consumed worldwide and are of great economic importance. In most species ripening is characterized by important visual and metabolic changes, the latter including emission of volatile organic compounds associated with respiration, destruction of chlorophylls, synthesis of new pigments (red/yellow carotenoids plus xanthophylls a...
Capsicum species produce fruits that synthesize and accumulate carotenoid pigments, which are responsible for the fruits' yellow, orange and red colors. Chili peppers have been used as an experimental model for studying the biochemical and molecular aspects of carotenoid biosynthesis. Most reports refer to the characterization of carotenoids and content determination in chili pepper fruits from...
For comparing the effects of two planting substrates on vegetative growth, flowering rate, fruit appearance and qualities, yield of four bell pepper (Capsicum annum L.) cultivars, a greenhouse 4×2 factorial experiment was done by using a completely randomized design with 4 replications. First factor was 80% cocopeat + 20% perlite and 80% mosspeat + 20% perlite and the second one was four bell p...
The objective of this work was to determine the effects of blanching and two drying methods, open-sun drying and natural convection solar drying, on the quality characteristics of red pepper. A 2 × 3 factorial design with experimental factors as 2 drying methods (open-sun drying and use of solar dryer) and 3 levels of pepper blanching (unblanched, blanched in plain water, and blanched in 2% NaC...
