A compensatory response, viz. in vivo recovery from radiation damage to mitochondria, occurs in preclimacteric pear fruits (Pyrus communis L.) treated with ionizing radiation. The compensatory response is absent or markedly impaired in senescent fruits irradiated at or near the climacteric peak. Senescent cells failed to recover from harmful effects of radiation on: 1) mitochondrial yield, 2) i...

Light-induced pigment destruction was studied in ripening apple (Malus domestica Borkh., cv. Antonovka) fruits with reflectance spectroscopy. The reflectance spectral changes attributable to light-induced transformation of xanthophyll cycle carotenoids (Car) preceded the pigment degradation. In green fruits, the destruction of chlorophyll and Car proceeded synchronously up to complete disappear...

Food allergy is a widespread phenomenon: An estimated 1–2% of the population suffers from some type of food allergy. Fruits and vegetables are considered among the most important elicitors of food allergy. Berry fruits rich in phenolic compounds including flavonols, flavones and anthocyanins have recently gained increasing interest due to their possible beneficial effects on human health. Howev...

In European folk medicine, the fruits of Juniperus communis are used in the treatment of skin-related disorders such as skin infection, itching, and psoriasis. Previously, we reported that the EtOAc fraction of J. communis (EAJC) contained tyrosinase inhibition properties in vitro non-cellular experiment. The aim of this study was to evaluate anti-melanogenic effect of standardized EAJC on a hy...

This presentation focuses primarily on recent developments in new technologies that have impacts on decay control. These technologies include 1-methylcyclopropene (1-MCP) and new preand postharvest fungicides. With the increasing use of 1-MCP in the apple industry, depending on varieties, many apples do not have to be drenched with diphenylamine (DPA) prior to storage. Because use of 1-MCP has ...

Metabolites in the fruits of edible plants include sweet sugars, visually appealing pigments, various products with human nutritional value, and biologically active plant hormones. Although quantities of these metabolites vary during fruit development and ripening because of cell division and enlargement, there are few reports describing the actual dynamics of these changes. Therefore, we appli...

The antioxidant activity of leav...

The comparative hypocholesteremic effect of feeding palm oil and palm oil mill effluent (POME) was investigated in male albino rats. Diets were prepared and designed to contain 50% of energy as carbohydrate, 35% as fat, and 15% as protein. Groups of six rats were each fed one of these diets, while a group was fed pelletized mouse chow which served as the control. Feeding on palm oil and POME le...
