The main objective of this study was to extract natural colorant from purple sweet potato powder (PSPP) via a water bath and ultrasound water bath using acidified ethanol (A. EtOH) as the extraction solvent. When optimizing the colorant extraction conditions of the solvents, acidified ethanol with
Fragaria × ananassa leaves extracts prepared in different solvents were subject for antioxidative, cytotoxicity, protein kinase inhibition and antibacterial activities. The extracts showed varying activities depending upon solvent used for extraction. Combined effect of methanol and ethyl acetate
Wild Fragaria vesca L. fruits were studied regarding nutritional and phytochemical compounds, and also antioxidant, antibacterial and biofilm formation inhibition activities. The fruits are good sources of carbohydrates (e.g., sucrose), soluble dietary fiber and polyunsaturated fatty acids, mainly
The purpose of this study was to examine if fermentation of purple sweet potato (Ipomoea batatas L.) powder (PSP) by Lactobacillus brevis under green, red, blue, white light-emitting diode (LED) illumination or sunlight might yield functionalized products with good antibacterial, antioxidant
Three chitin-binding proteins (CBPs: CBP9, CBP15, CBP66) were identified from the larval hemolymph of sweet potato hornworm, Agrius convolvuli. Two (CBP9 and CBP15) of them have been isolated and purified by gel filtration (Superdex HR 75), cation-exchange chromatography (Mono S), and reverse-phase
New sanitization methods have been evaluated to improve food safety and food quality and to replace chlorine compounds. However, these new methods can lead to physicochemical and sensory changes in fruits and vegetables. The present study evaluated the effects of acetic acid, peracetic acid, and
Xanthomonas fragariae, the causal agent of angular leaf spot (ALS) of strawberry, is a quarantine pathogen in some export markets, causing trade restrictions and economic loss to the California fresh-market strawberry industry. Preharvest chemical management options are limited to copper, and
This study posed a novel strategy of interweaving carboxymethyl chitosan (CMCS) and HKUST-1 to build eco-friendly, recyclable, long-acting and intelligent antibacterial agent carrier of HKUST-1@CMCS. Combined characterizations revealed that the structure of HKUST-1@CMCS was destroyed step by step
Background
Ipomoea batatas (L.) Lam.(Ib) has high content of various beneficial nutrients which helps in improving and maintaining human health. It is well known as a functional food and also a valuable source of unique natural products. It contains various phenolic and
This study determined the bactericidal effect of the supernatants of saturated solutions of common lime and of micronized calcium hydroxide (Ca(OH)2) (1500 mg/L), which was used as a control, compared with disinfectants made of solutions of 0.33% colloidal silver (0.0016 mg/L), toluene
Essential oils obtained by hydrodistillation (HD) and microwave-assisted HD (MWHD) of Origanum onites aerial parts were analyzed by GC and GCIMS. Thirty-one constituents representing 98.6% of the water-distilled oil and 52 constituents representing 99.6% of the microwave-distilled oil were
In this paper, we report on a novel strategy for the preparation of silver nanoparticle-doped SiO(2) microspheres (Ag-SMSs) with an interesting strawberry-like morphology using a simple and efficient electrospraying method. SEM (scanning electron microscopy), TEM (transmission electron microscopy),
Antibacterial activity of electrolyzed oxidizing (EO) water prepared from 0.05% or 0.10% (w/v) sodium chloride (NaCl) solutions against indigenous bacteria associated with fresh strawberries (Fragaria x ananassa) was evaluated. The efficacy of EO water and sodium hypochlorite (NaOCl) solution in
The progress of angular leaf spot, caused by the bacterium Xanthomonas fragariae, was examined in field plots of strawberry in the 1994 and 1995 seasons. Disease severity increased intermittently to maxima of circa 25% in 1994 and 15% in 1995. Angular leaf spot reduced marketable yield 8.6% in 1994
