“…However, changes in total organic acid content in response to 1-MCP treatment or storage duration were different from changes in titratable acidity or pH (Table 1). Previously, we reported different organic content among these five apple cultivars [26]. At harvest, we found that the total organic acid content was the lowest in "Pixie Crunch" [26].…”

“…Our results also show that change in total phenolic content during storage was different among cultivars. However, total phenolic content after storage was generally lower in all cultivars [26]. Increase in total phenolic content in response to 1-MCP treatment was reported in "Red Delicious" [41], while, in "Cripps Pink," Hoang et al [42] reported a twofold increase in the flesh and about 10% decrease in the peel after 160 days of storage.…”

“…"GoldRush" and "CrimsonCrisp" exhibited the highest total antioxidant capacity, as measured by ABTS and FRAP, in response to 1-MCP treatment (Table 3). These cultivars were also found to be the highest in antioxidant capacity at harvest [26]. However, antioxidant capacity measured by ABTS generally decreased while that analyzed by FRAP assay increased after storage.…”

Scab (Venturia inaequalis) is a very serious disease for apples causing up to 80% of loss in yield but there are only a few studies on postharvest quality of scab-resistant cultivars. In this study we evaluated the effect of 1-methylcyclopropene (1-MCP) on fruit quality, total phenolic content, and antioxidant capacity after storage of four scab-resistant cultivars and compared to a standard cultivar, "Golden Delicious." In general, ethylene production and respiration rates significantly differed among cultivars, between control and 1-MCP-treated fruits, and between storage duration regimes. 1-MCP treatment retarded fruit softening and lowered juice pH but storage effect on soluble solids and acidity depended on cultivar and 1-MCP treatment. Total phenolic content was significantly affected by storage duration and 1-MCP treatment. Antioxidant capacity of the four scab-resistant cultivars was either similar to or significantly higher than that of "Golden Delicious" with the 1-MCP-treated fruits having significantly higher antioxidant capacity than the nontreated fruits after storage. Our results clearly show that the quality of four scab-resistant cultivars was comparable to that of "Golden Delicious" and 1-MCP effect differed among cultivars. These differences need to be considered in developing storage regime to minimize quality deterioration during long-term storage. IntroductionThe hazardous effects of pesticides on human health and the environment have contributed to the introduction of cultivars with effective resistance genes to major plant diseases. Yield losses from fungal diseases are significant in most apple producing countries worldwide. Apple scab, caused by the fungus Venturia inaequalis, is one of the most destructive diseases of apples throughout the world, causing up to 80% loss in yield without chemical intervention, which could include multiple classes of fungicides applied up to 22 times during the growing season [1]. In 1944 Hough, from University of Illinois, was the first to identify the scab-resistant gene in Malus floribunda [2]. Since 1944, additional scab-resistant genes have been identified in other apple species [3]. In 1948, three US universities (Purdue, Rutgers, and Illinois, PRI) formed a research team to develop apple cultivars resistant to scab, utilizing the gene [3]. In recent years, several apple cultivars containing have been introduced into commercial production from the PRI program, including "Dayton," "Prima," "Priscilla," and "Jonafree" [4]. Among the most promising introductions are "WineCrisp" [5], "CrimsonCrisp" [6], "Pixie Crunch" [7], and "GoldRush" [8]. In addition to the scab-resistant apple cultivars released by the PRI breeding program, several cultivars have also been released by breeding programs at Cornell University in NY, by Agriculture Canada, and by the National Institute of Agronomic Research in Angers, France, and Consorzio Italiano Vivaisti in Italy, and Breeding Initiative Niederelbe in Germany [9].Despite the introduction of several apple scab-resis...

Investigated cosmetic cream was pale beige color, odorless, semi-solid consistency and homogeneous, with pH values of 6.53±0.14, electrical conductivity above 50 μS/cm and AA of 24.96%RSC after preparation and these characteristics were stable during investigated period. In vivo measurements revealed absence of skin irritation after cream application under occlusion, which was part of it's safety profile. Increase of skin hydration after 14 days of cream application was 17.28±12.23 and after 28 days 21.19±7.59. In addition, in performed experiment TEWL and skin pH values during cream application remained unchanged. Cream application after artificial hyperpigmentation induced decrease of MI (∆MI after 7 days was -45.30±18.55) CONCLUSION: Formulated cosmetic cream with 6% of standardized wild apple fruit water extract and stabilized by biodegradable alkyl-polyglucoside emulsifiers demonstrated good stability, acceptable level of in vitro antioxidant activity, absence of skin irritation after cream application under occlusion and positive effects of cream on human skin after application (hydrating and bleaching effects). All mentioned properties make the cream suitable for possible usage as cosmetic product for preventing the skin damages caused by oxidative stress, for moisturizing the dry skin and bleaching of skin hyperpigmentation.

Objective The aim of the study was in vitro and in vivo characterization of cosmetic cream with 6% of standardized wild apple fruit extract, stabilized by conventional non‐ionic emulsifier‐CEW, in order to determine the influence of emulsifiers (conventional vs. biodegradable) on the characteristics of creams and their effects on the skin. Methods Organoleptic and physico‐chemical (pH values and electrical conductivity) analysis was performed, determination of fruit acids‐FAs content (using HPLC analysis) and estimation of its antioxidant activity‐AA (using DPPH test) during 180 days. In vivo study included following examinations: screening of safety profile (after creams application under occlusion during 24 h at human skin); skin moisturizing potential, transepidermal water loss‐TEWL, skin pH after 28 days of cream application and hypopigmentation efficacy 7 days of cream application at artificially induced skin hyperpigmentation. Results Investigated cosmetic cream‐CEW showed satisfactory organoleptic, physico‐chemical characteristics, stability, FAs content (0.13%) and AA (19.25 ± 0.67 %RSC) after preparation, which remained unchanged over the study period. In vivo investigation revealed absence of skin irritation after CEW's application under occlusion. An increase of skin moisturization (after 14 days ΔEC was 18.52 ± 11.51 and after 28 days of applications 16.52 ± 9.36) during 28 day‐study, with unchanged TEWL and skin pH values was shown. Decrease of melanin index was revealed, too (after 7 days ΔMI was −31.40 ± 16.50). Conclusion Cosmetic cream stabilized by conventional emulsifier showed better antioxidant potential and weaker moisturizing and hypopigmentation effects related to the cream with same composition but stabilized by biodegradable emulsifiers. Based on all mentioned above, investigated cosmetic cream might be considered for potential use as modern, stable, safe and efficient cosmetic product in the prevention and/or treatment of oxidative stress‐related skin changes and/or damages, for moisturization of dry, even irritated skin as well as for lightening of hyperpigmented skin. Résumé OBJECTIFLe but de l’étude était la caractérisation in vitro et in vivo d'une crème cosmétique contenant 6 % d'extrait normalisé de pomme sauvage, stabilisée par un émulsifiant non ionique conventionnel‐CEW, afin de déterminer l'influence des émulsifiants (conventionnels vs biodégradables) sur les caractéristiques des crèmes et les effets sur la peau. MÉTHODES Des analyses organoleptiques et physico‐chimiques (pH et conductivité électrique) ont été effectuées, la détermination de la teneur en acides de fruits et en acides gras polyinsaturés (par CLHP), et l'estimation de sa teneur en activité antioxydante (AA) (à l'aide du test DPPH) pendant 180 jours. L’étude in vivo comprenait les examens suivants : dépistage du profil d'innocuité (après application de crèmes sous occlusion pendant 24 h sur la peau humaine); potentiel d'hydratation de la peau, perte d'eau transépidermique (PETE), pH de la peau après 28 j...
