The aim of this work is to develop a simple and rapid method for determination of β-carotene in carrot by spectrophotometry. Extraction of β-carotene from carrot was investigated and the proposed method was validated and applied for quantitation of β-carotene in carrot samples obtained from various places.
Headspace Volatile Evaluation of Carrot Samples—Comparison of …
2019年7月27日 · The performances of a quartz crystal microbalances (QCMs) based on an electronic nose (E-nose), modified with hairpin-DNA (hpDNA) for carrot aroma profiling has been evaluated. Solid phase micro-extraction (SPME) headspace sampling, combined with gas chromatography (GC), was used as a reference method. The changes in carrot aroma profiles ...
Biocrystallization-sequence of a carrot sample from the field to …
With the analytical approach, samples from different radiation intensities and N supply levels were identified correctly in two out of two sample sets with groups of five samples per treatment ...
Quantitative measurement of internal quality of carrots using ...
2024年4月12日 · This study investigated HSI to determine carrots' internal quality, Car, and pH, focusing on the effects of sampling regions of two cultivars. The results indicated that the cortex or xylem...
Osmosis in potato and carrot samples. Introduction. Osmosis is the movement of water molecules through a selectively permeable membrane into a region of higher solute concentration, until there is an an equal solute concentration on the two sides. Osmosis is essential in biological systems, as biological membranes are semipermeable.
Standardization of the Biocrystallization Method for Carrot Samples
2010年1月1日 · For the test of repeatability, one carrot sample was prepared in parallel six times and all sample solutions crystallized with six dishes per chamber. The trial

Effect of Electrohydrodynamic Drying on Drying Characteristics …
2023年11月23日 · Four phytochemicals found in carrots are phenolics, carotenoids, polyacetylenes, and vitamin C. These compounds possess antioxidant, anti-inflammatory, plasma lipid regulation, and anti-tumor properties, which help to reduce the risk of cancer and cardiovascular diseases [ 1 ].
Non-destructive quantitative analysis of carotene content in carrots ...
2021年5月31日 · The aim of this study was to develop a non-destructive method for the determination of carotene content in carrots using Raman spectroscopy combined with chemometrics. Raman spectra of carotene and carrot were collected to determine the Raman peaks of carotene in the carrot’s Raman spectrum.
Effect of High-Pressure Processing on the Qualities of Carrot Juice ...
2023年8月18日 · This study examines the impact of blanching (heating at 85 °C for 60 s), high-pressure processing (HPP) (600 MPa, 3 min, 20 °C), and a combination of both blanching and HPP on the microbiological and chemical qualities, colour, and antioxidant properties of carrot juice stored at 4 °C for 15 days.
