Fast detection and location of longan fruits using UAV images

Computers and Electronics in Agriculture, 2021
Abstract In agriculture, fruit picking robots on the ground have difficulty adapting to the terrain conditions of mountain orchards and cannot pick longan fruit from tall longan trees. In this paper, aiming to allow picking of longan fruit by unmanned aerial vehicles (UAVs), a deep learning-based scheme to quickly and accurately detect and locate ...

CONTROL OF POSTHARVEST DISEASES IN LONGAN FRUIT BY OZONE

Acta Horticulturae, 2005
In order to study the effects of ozone gas treatment on postharvest diseases of longan fruits, cultures of the fungi Lasiodiplodia sp. and Cladosporium sp. cultured on potato dextrose agar (PDA) were exposed to 20 ppm of ozone. The ozone was applied directly on mycelia of Lasiodiplodia sp. or spore suspension of Cladosporium sp.

CHANGES OF PROTEIN COMPOSITIONS IN POSTHARVEST LONGAN FRUIT

Acta Horticulturae, 2010
The changes in composition of proteins in pericarp and flesh in the longan (Dimocarpus longan Lour. cv. Fuyan) were studied with an aim to discuss the relationship between proteomic and senescence. The protein was separated by SDS-PAGE and Native-PAGE. The results showed that fruit proteins tend to degrade consistently.

Characterisation of nutritional, physiochemical, and mineral compositions of aril and seed of longan fruit (Dimocarpus longan L.)

International Food Research Journal, 2021
Longan (Dimocarpus longan L.) seeds are usually discarded without further utilisation in food production. In the present work, to determine the food resource value of longan seeds, their nutritional components, bioactive materials, and antioxidant activity were compared with those of the longan aril, the edible portion.

VACUUM COOLING OF LONGAN FRUIT AFTER HARVEST

Acta Horticulturae, 2008
Since longan fruit mature during the hot season and the fruit are very perishable, pre-cooling is strongly recommended to remove field heat and reduce the respiration rate of fruit before storage or transportation. Vacuum cooling is the most rapid cooling method for post-harvest horticultural crops. A kinetic model of vacuum cooling fruit based on Fick

Finite Element Simulation of Drying of Longan Fruit

Drying Technology, 2008
A two-dimensional finite element model has been developed to simulate moisture diffusion in longan fruit during drying and moisture diffusivities of the components of longan fruit determined experimentally are used in this simulation. Shrinkage of the flesh of longan during drying is also taken into account.

Structural characterisation of polysaccharides purified from longan (Dimocarpus longan Lour.) fruit pericarp

Food Chemistry, 2009
In this work, crude polysaccharides were extracted from longan fruit pericarp by hot water. After removal of proteins and purification by Sephadex G-100 gel filtration column, polysaccharides of longan fruit pericarp (PLFP) were subjected to structural identification.

PHYSIOLOGICAL CHANGES IN LONGAN (DIMOCARPUS LONGAN LOUR.) FRUIT DURING CONTROLLED ATMOSPHERE STORAGE

Acta Horticulturae, 2010
Longan (Dimocarpus longan Lour.) fruit cv. Daw harvested at the commercial stage were enclosed in controlled atmosphere (CA) chambers ventilated with 2 or 4% O 2 combined with 5 and 15% CO 2 (balance N 2 ) or air (control) at 4°C and 95% relative humidity.

High pressure extraction of corilagin from longan (Dimocarpus longan Lour.) fruit pericarp

Separation and Purification Technology, 2009
Abstract High pressure as a new extraction technique was carried out to extract corilagin from longan fruit pericarp. The effects of different solvents, solvent concentration and solid to liquid ratio on corilagin contents were individually determined.

STUDY ON THE FLOWERING AND FRUITING PHENOLOGICAL LAW OF 'SIJIHUA' LONGAN (DIMOCARPUS LONGAN) AND ITS REGULATION

Acta Horticulturae, 2010
According to the phenological characters of 'Sijihua' longan (Dimocarpus longan Lour.), the effects of several plant growth regulators on the flower formation and the fruit setting were investigated through the multi-factors orthogonal experiment design in this study.
