چکیده
In this study, 17 edible flowers (Allium ursinum L., Borago officinalis Calendula Centaurea cyanus Cichorium intybus Dianthus carthusianorum Lavandula angustifolia Mill., Leucanthemum vulgare (Vaill.) Lam., Paeonia Primula veris Robinia pseudoacacia Rosa canina pendulina Salvia pratensis Sambucus nigra Taraxacum officinale Weber, and Tropaeolum majus L.) were investigated to assess their sensory profile at harvest shelf life bioactive compounds dynamics during cold storage. The emerging market of lacks information; thus, the characteristics requirements different flower species provided. detail, a quantitative descriptive analysis was performed by trained panelists harvest, evaluating 10 descriptors (intensity sweet, sour, bitter, salt, smell, specific aroma, herbaceous aroma; spiciness, chewiness, astringency). Flower visual quality, biologically active content (total polyphenols anthocyanins), antioxidant activity (FRAP, DPPH, ABTS assays) evaluated both storage 4 °C for 14 days life. Generally, had wide range peculiar phytochemical as well postharvest. A strong aroma indicated A. ursinum, D. carthusianorum, L. angustifolia, vulgare, while B. C. very low values all taste descriptors, resulting in poor profiles. At P. officinalis, R. canina, exhibited highest (884–1271 mg gallic acid equivalents per 100 g) (204–274 mmol Fe2+/kg FRAP, 132–232 43–58 µmol Trolox equivalent g DPPH ABTS). with longest terms acceptable quality (14 days), followed (10 days). All other lasted seven days, except T. that did not reach day 3. During storage, differed, total phenolics trend according anthocyanins remained almost unaltered days. Considering activity, least variable, varying only four (A. officinalis), FRAP varied eight species. Taken together, knowledge profiles, can provide information select suitable market.

Preservative Effect of Chitosan Coating on Shelf Life and Sensory Properties of Chicken Fillets during Chilled Storage
Background: Chicken fillets contain essential amino acids besides many minerals and vitamins, which are necessary for maintaining life and promoting growth. Moreover, it is low in calories and cholesterol; therefore, it can be used for feeding infants, young children, and some patients. Methods: Chicken fillets were initially coated by dipping in different concentrations of chitosan (1.0%, 1.5...
متن کاملBioactive Edible Coating for Shelf Life Improvment of Organic Strawberries
Organic foods have great importance in environment sustainability and human nutrition. However, they are commercialized with greatly reduced shelf life, especially fruits and vegetables. Considerable amounts of vegetables are lost due to their rapid deterioration by microorganisms such as fungi and bacteria. In this work cell wall degrading enzymes (CWDE) produced by Trichoderma asperellum (T00...

Effects of Shirazi Gum Edible Coating Containing of Peppermint Essential Oil on Shelf-life of Fresh Greenhouse Cucumbers (Cucumissativus) and Its Quality Assessment during Storage in Refrigerator
Background and Objectives: Greenhouse cucumber is one of the most important summer crops of Iran. Quality of the product is immediately lost after harvest due to physicochemical changes. Thus, use of special pre-processes (especially use of edible coating) to delay their maturity and increase the shelf-life of the product is important. Materials and Methods: To decrease weight loss, preserve nu...
