Tea tree essential oil and its impact on blue mold, volatile compounds, and postharvest quality of 'Fuji' apples: A study of laboratory-extracted and commercial essential oils.

This study evaluated the effects of tea tree essential oil (TTO) on blue mold severity, volatile compound profiles, and postharvest quality of 'Fuji' apples during cold storage. Two experiments were conducted using laboratory-extracted TTO from Brazil and commercial TTO from Australia, applied by vaporization at various concentrations. Both types of TTO affected major volatile compounds, including terpinen-4-ol, γ-terpinene, and α-terpinene.

Salivary β-glucosidase as a direct factor influencing the occurrence of halitosis.

β-Glucosidases are enzymes present in all living organisms, playing a pivotal role in diverse biological processes. These enzymes cleave β-glycosidic bonds between carbohydrates, or between a carbohydrate and a non-carbohydrate moiety, which may result in the liberation of volatile aglycones. Released compounds execute diverse physiological roles while the industry takes advantage of exogenously added β-glucosidases for aroma enrichment during food and beverage production.

Meta-analysis of magnetic resonance imaging accuracy for diagnosis of oral cancer.

Objective: To establish the diagnostic accuracy of magnetic resonance imaging (MRI) as an auxiliary means for the diagnosis of oral cancer through a systematic review and meta-analysis.

Methods: An exhaustive search of publications from 1986 to 2016 was performed of Medline, Embase and Cochrane (and related databases), including grey literature. Primary diagnostic accuracy studies that assessed oral cancer (target condition) using MRI (index test) were included.

Phenolic Content and Antioxidant Activity during the Development of 'Brookfield' and 'Mishima' Apples.

The aim of this study was to characterize the changes in the contents of total (TPC) and individual (IPC) phenolic compounds, the total antioxidant activity (TAA) in the peel and pulp, and total anthocyanins (TAN) in the peel during the development of the fruits of 'Brookfield' and 'Mishima' apple trees. 'Brookfield' apples were harvested from the 49th to the 138th days after full bloom (DAFB) and 'Mishima' apples from the 45th to the 172th DAFB. In the pulp, the IPC, TPC, and TAA rapidly reduced at 75 and 79 DAFB for the 'Brookfield' and 'Mishima' apples, respectively, and then remained constant until commercial maturity.

Efficiency of basalt zeolite and Cuban zeolite to adsorb ammonia released from poultry litter.

Confined poultry production is an important livestock activity, which generates large amounts of waste associated with the potential for environmental pollution and ammonia (NH) emissions. The release of ammonia negatively affects poultry production and decreases the N content of wastes that could be used as soil fertilizers. The objective of this study was to evaluate a low-cost, simple and rapid method to simulate ammonia emissions from poultry litter as well as to quantify the reduction in the ammonia emissions to the environment employing two adsorbent zeolites, a commercial Cuban zeolite (CZ) and a ground basalt Brazilian rock containing zeolite (BZ).
