Phytochemicals in plants, vegetables and fruits have been reported to prevent oxidative stress related diseases, such as cancer, cardiovascular disease, cataracts, brain and immune-system dysfunction and inflammation. Many plant phenolic flavonoids have been shown to have antioxidant activity. In our study, the polyphenolic content and the radical scavenging activity of a number of Thai fruit e...

Osmotic dehydration has received greater attention in recent years as an effective method for preservation of fruits and vegetables. Being a simple process, it facilitates processing of fruits and vegetables such as banana, sapota, fig, guava, pineapple, apple mango, grapes, carrots, pumpkins, etc. with retention of initial fruit characteristics viz., colour, aroma, texture and nutritional comp...

The present investigation was conducted in the University Laboratory, RVSKVV, Gwalior, MP, India during period of February, 2020 to March, 2021. Guava fruits were randomly collected and cleaned tap water remove surface dust leaves before weighing, sorting. This study limited five guava varieties viz., Allahabad Safeda, Gwalior-27, Lucknow- 49, Sheopur local Lalit. maximum fruit weight (292.14 g...

A field experiment was conducted during 2020-2021 at Horticulture Research Farm-1, BBAU, Lucknow on 15- year- old guava plants, Studies the Effect of Zinc and Boron Growth, Yield Quality Guava (Psidium guajava L.) cv. L-49”, revealed Number fruits per tree, tree (kg), Total chlorophyll content (mg/g), Average weight fruit (g), Volume (cc), TSS ( 0Brix), Acidity (%), Ascorbic acid in pulp (mg/10...

In this study copper nanoparticles were synthesized using extracts from Solanum lycopersicum (Tomato) and Psidium guajava (Guava) fruits. The synthesis process optimized experimental conditions such as temperature, concentration of precursor amount fruit extract. characterized Uv-vis, FTIR, XRD, SEM EDX techniques. Copper with tomato guava had diameters 52nm 25nm, respectively. antibacterial ac...

The root knot nematode (Meloidogyne incognita) was reported to cause severe damage in guava cultivation in Malaysia. Several long term approaches were taken to find sustainable control for the root knot nematode through breeding. The approaches include protocol development to screen nematode resistance in Psidium species, genetic resource establishment in the field, screening of accessions agai...

The Brazilian guava processing industry generates 5.5 M Mg guava waste year(-1) that could be recycled sustainably in guava agro-ecosystems as slow-release fertilizer. Our objectives were to elaborate nutrient budgets and to diagnose soil, foliar, and fruit nutrient balances in guava orchards fertilized with guava waste. We hypothesized that (1) guava waste are balanced fertilizer sources that ...

Guava is a nutritious fruit that has perishable behavior during storage. We aimed to determine the influences of some edible coatings (namely, cactus pear stem (10%), moringa and henna leaf (3%) extracts incorporated with gum Arabic (10%)), on guava fruits’ properties when stored under ambient refrigeration temperatures for 7, 14, 21 days. The results revealed coating (10%) only, or combined na...
