oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...

Preclimacteric 'Rocha' pears stored under chilling conditions, had a larger increase of ACO (1-aminocyclopropane-1-carboxylate oxidase) activity and softened faster than those treated with ethylene. Non-treated fruit did not ripen or soften, acquired a rubbery texture, and showed barely detectable levels of ACO activity. The transcript accumulation of seven genes encoding cell wall modifying en...

background: obesity is growing rapidly in our country. nutrition is an important associate of obesity. the aim of this study was to determine the association between fruit and vegetable intake with the waist circumference and the body mass index (bmi) among young female university students.   methods: this cross sectional study was conducted on 236 healthy female university students aged betwee...

Fruit production has faced many challenges in recent years as society seeks to increase fruit consumption while increasing safety and reducing the harmful effects of intensive farming practices (e [...]

Fruit quality of five scab resistant apple cultivars (Enterprise, Liberty, Nova Easygro, Sir Prize and Rewena) suitable for organic growing systems were tested. External and internal fruit quality was assessed through standard parameters (fruit weight, firmness, soluble solids, malic acid) and sensorial quality by panel tests (fruit size, shape and colour; hardness, texture, juiciness, sweet/ac...

The application of pesticides to fruit throughout the Northeastern US, as in the rest of the world, gives rise to concern, primarily due to inaccurate application, which often results in high residues and environmental pollution. Inaccuracy, due to overor under-application, may result in high levels of disease or insect activity. Air and water pollution resulting from pesticide drift is a major...

Astringency is one of the most important components of fruit oral sensory quality. Astringency mainly comes from tannins and other polyphenolic compounds and causes the drying, roughening and puckering of the mouth epithelia attributed to the interaction between tannins and salivary proteins. There is growing interest in the study of fruit astringency because of the healthy properties of astrin...
