The behavior of Salmonella spp. on fresh-cut dragon fruit, banana, starfruit, mango, pineapple, guava and wax apple at 28°C and 4°C was studied. Growth of Salmonella on the fresh-cut starfruit was studied at 7, 10, 15, 20, 25 or 30°C. Tropical fruits were cut into cubes and spot inoculated with...

Mangosteen (Garcinia mangostana L.) is one of the most popular tropical fruits (called the "Queen of Fruits"), and is a rich source of oxygenated and prenylated xanthone derivatives. In the present work, phytochemical investigation has resulted in one new prenylated xanthone and 13 known xanthones...

The seasonality of citrus fruits and their susceptibility to postharvest mold decay can cause huge economic losses to the citrus industry. The surface of citrus fruits is covered with a hydrophobic layer called the cuticle, which can prevent non-stomatal water loss, resist the invasion of...

To evaluate the pesticide residues in bananas and short-term dietary risk, 196 samples were analyzed and short-term dietary risk to adult and children (1-6 years) was calculated. The most frequently detected pesticides in whole bananas were prochloraz (42.86%), pyraclostrobin (40.82%), imidacloprid ...

Background: Syzygium samarangense (Wax apple) is an important tropical fruit tree with high economic and nutrient value and is widely planted in the tropics or subtropics of Asia. Post-harvest water-soaked brown lesions were observed on mature fruits of ornamental wax apples in Chiang Rai...

In order to solve the problem of injury to seedlings caused by existing grafting machine and improve the operation flexibility and safety of grafting mechanism, two typical melon seedlings, cucumber and watermelon were taken as the research objects, and cucurbita moschata and gourd seedlings were...

Psidium guajava fruit is a subtropical fruit, functional food and traditional medicine for the adjuvant treatment of diabetes mellitus in China. To investigate the active components responsible for its health benefits, a novel heteropolysaccharide GP70-3 was purified by water extraction, ethanol...

Objective: To develop an analysis method for determination of 3 kinds of pesticide residues in guava by gel permeation chromatography-gas chromatography-tandem mass spectrometry (GPC-GC-MS/MS). Methods: The guava samples were extracted by acetonitrile, followed by a cleanup procedure with GPC, and...

Meroterpenoids isolated from guava (Psidium guajava) and Rhodomyrtus tomentosa possess special skeletons which incorporate terpenoids with phloroglucinol derivatives. Most of these meroterpenoids showed high cytotoxicity against cancer cell lines. However, their chemical diversity is very limited....

Objective: An infectious clone of citrus yellow mosaic virus (CYMV) was constructed to lay a foundation for further study of its molecular characteristics and pathogenic mechanism. Method: The amplified CYMV genomic sequence segments were recombined with the ternary expression vector pCY using...
