| In the current dairy industry, an intensive demand for estrus detection and early diagnosis of pregnancy has been increasing. Progesterone is a steroid hormone that is secreted from corpus luteum into bovine blood and milk, and has a role of maintenance of estrus cycle and pregnancy. Therefore, progesterone concentration in bovine milk is used as an important indicator of estrus detection and early diagnosis of pregnancy. Current method for milk progesterone determination requires a hormone extraction procedure that is time consuming, various types of instruments, reagents management, and various assay methods that are destructive in nature. In contrast, near-infrared spectroscopy (NIRS) is a time saving and non-destructive analytical method that can be... |

| Abstract Strains of Bacillus subtilis increase plant growth and yield. Consequently, the application of Mexican native strains of B. subtilis on greenhouse-grown melon (Cucumis melo L.) plants should induced a significant improvement on plant development and fruit quality. The objective of this study was to evaluate the effect of LAL-36, BEB-23, BEB-22 and BEB-13 B. subtilis strains, native to Mexico, on melon plant development and fruit quality. The strains were placed separately into the rhizosphere of melon plants under greenhouse conditions. Plants were grown in clinoptilolite type zeolite. Five treatments were evaluated: four inoculated with one of the four B. subtilis strains and one control without bacterial inoculum. A completely randomized design... |

| The physical-chemical quality changes in mangaba fruit were studied. The fruit which attained full development at half-ripe stage were harvested and initially stored at 6, 8, 10 and 12±1ºC for four days. After this period, the fruit were transferred to an acclimatized room (24±2ºC) and maintained for five days. For control purposes, recently harvested fruit were stored directly in an acclimatized room (24±2ºC) for six days. After the transfer and storage at 24ºC, fruit were analyzed daily for their vitamin-C, soluble solids (ºBrix), titratable acidity, pH and firmness contents. In fruit directly stored at 24ºC, there was a sharp fall in vitamin C and acid contents. The fruit firmness decrease, after four days of storage, and they turned totally ripe. The... |

| ABSTRACT: Despite the fact that cold storage and modified atmosphere techniques have already been studied for fresh cut Star fruit, little has been done considering the whole fruit. Besides that, each cultivar has its peculiarities, so the efficiency of combined postharvest treatments should be studied. The objective of this study was to evaluate the effect of polyvinyl chloride (PVC), 8.5 µm thick and low-density polyethylene (LDPE), 33 µm thick associated with cold storage (10 ± 1 °C and 5 ± 1 °C / 85 ± 5% RH) on the conservation of ‘Malasia’ Star fruit. Storage at 25 oC maintained Star fruit overall quality, regardless of the film type, up to four days. The weight loss was higher in fruit packed with PVC, but this fact was not noticed by the sensory... |

| ABSTRACT: Native fruits are economically important to small producers, and they are a important part of the diet of several communities. Therefore, postharvest studies of these fruits are essential. In addition, research involving their chemical composition can identify substances that add potential value to the fruits, especially from a nutritional and medicinal standpoint. This study characterized the fruits of the muricizeiro shrub (Byrsonima crassifolia, Malpighiaceae), which were harvested from native plants on private properties and stored for 16 days at a mean temperature of 12 °C. The fruits were evaluated during storage for: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, ascorbic acid content, phenolics and carotenoids total,... |
