Development of analytical methodology for verification of authenticity of apple juice

Creator:: Lee, Hyoung S.
Abstract:: Apples growing in New Zealand, Argentina, Mexico, Michigan and Washington were used to provide the compositional data and to develop the analytical procedures for the use in verification of authenticity of apple juices. High Performance Liquid Chromatography (HPLC) techniques were applied for glucose, fructose, sucrose, sorbitol, malic, citric, quinic, shikimic,...

The blueberry : composition, anthocyanins, and polyphenolics

Creator:: Lee, Jungmin
Abstract:: Frozen blueberries were pilot-plant-processed into juice and concentrate by 2 treatments (heat and SO2), and a control. Qualitative, and quantitative anthocyanin and polyphenolic content were monitored after each processing step. Major losses occurred after the initial processing steps. Juice processing by-product contained a substantial amount of anthocyanins and polyphenolics (>42%...

Influence of processing and storage on the phenolic composition of apple, pear and white grape juice

Creator:: Spanos, George A.
Abstract:: Methodology for characterization of the phenolic profile of apple, pear and grape juice was developed. It utilized High Performance Liquid Chromatography (HPLC) for separation of individual phenolic compounds and Diode Array Detection for recording the Ultra-violet (UV) spectrum of chromatographic peaks. The high resolution achieved and the ability of recording...

Characterization and detection of potential adulterants in apple juice by pattern recognition methods

Creator:: Pilando, Leticia S.
Abstract:: Fruit juice concentrates- hard pear, soft pear, fig, prune, raisin, white grape, and pineapple, and sweeteners-invert beet, invert cane, and high fructose corn syrup (HFCS) were characterized by sugar profiles, nonvolatile acid profiles, UV spectral profiles, and mineral content. These fruit juices and sweeteners were also used to adulterate commercial...

The role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

Development of a process for production of cantaloupe juice concentrate and determination of its composition and quality

Creator:: Galeb, Abduljalil Derhm Saeed
Abstract:: Fresh ripe, cantaloupes were processed into juice and juice concentrate. Processing trials were conducted on fresh and frozen fruits with and without rind. The effects of maceration enzymes and fining agents on yield and quality were investigated. Compositional measurement included °Brix, pH, titratable acidity, formol values, ascorbic acid content, total...

Apple polyphenolics and their antioxidant properties : influence of cultivars, post-harvest storage, and 1-MCP treatment

Creator:: Widyasari, Maria Angela Artania
Abstract:: The distribution of total phenolics, antioxidant capacity, monomeric anthocyanin, and ascorbic acid contents in the peel and flesh of Red Delicious, Granny Smith, and Fuji apples during a six-month storage period were determined. In addition, the effect of 1-MCP (1-Methyl cyclopropene) on these parameters of the edible portion of apples...
