Quantitative risk assessment of acquiring listeriosis from consumption of minimally processed vegetables
Listeriosis is a serious invasive disease with high fatality rates especially among the vulnerable population. Although the causative pathogen had been detected in several foods in Malaysia, there have so far been no reported cases of listeriosis in Malaysia. The aim of this study was to carry out a quantitative risk assessment to estimate the risk of acquiring listeriosis through the consumption ...

Polyphenol oxidase activity and colour changes of peeled potato (cv. Monalisa) in vacuum
Minimal processing of vegetables has some undesirable physiological consequences. The shelf life of peeled raw potatoes is limited by the onset of enzymatic browning at the cut surfaces. It is generally accepted that polyphenol oxidase (PPO) is the enzyme mainly responsible for this type of browning. This work aimed to study the effect of vacuum storage at 4?C on the colour, which is the main ...

Food Processor
Problem: A major food processor and food supplier lo airline companies was out of compliance due to the failure of their wastewater treatment system to perform effectively in reducing the contaminants and meet discharge requirements. They needed to deal with their wastewater efficiently and cost-effectively, and ultimately achieve compliance with the authorities discharge standards. Solution: ...

Fruits and Vegetables Hot Air Drying Processes Research
Hot air drying is the conventional drying method, and it transfers heat from the drying medium to the material based on the heat conduction effect, then this results in two diffusion after the material absorbs heat: the external diffusion ( the moisture from the material surface to the drying medium ) and the internal diffusion ( the moisture from material interior to the material surface ), and ...

Multiscale control of vegetation patterns: the case of Doñana (SW Spain)
The early studies about the plant ecology of Doñana carried out at a small scale showed that the main process controlling vegetation composition of the stabilized dunes was soil water availability. However, the extrapolation of this model to larger spatial scales failed to explain observed vegetation patterns. In this work, the vegetation patterns and the processes causing them are studied at a ...

Minimal models and agroecological policy at the regional scale: An application to salinity problems in southeastern Australia
A minimal dynamical systems model that couples agricultural activity, native vegetation, and hydrological processes is developed to explore policy options regarding regional-scale soil and water salinization in southeastern Australia. The analysis suggests that although considerable revegetation is required to restore catchment water balance, the current value of water in uses other than ...

Hielscher – Ultrasonic Transesterification of Oil to Biodiesel Improves Reaction Speed and Yield
Ultrasonication can improve the conversion processing of vegetable oils or animal fats to biodiesel by improved mixing and enhanced chemical activity. The manufacturing of biodiesel from oils (e.g. soy, canola, sunflower seed) or animal fats, involves the base-catalyzed transesterification of fatty acids with methanol to give the corresponding methyl esters. The conventional esterification ...

Onion Slices Drying Processes
The dehydrated vegetable is a kind of food with popularity to meet the fast-paced and high-efficiency life style of nowadays. After drying, the moisture content of vegetables are reduced to 4%-13%, and the water activity (Aw) is reduced to around 0.7, which makes the microorganism and enzyme in an inhibition state, thus the dried vegetable can be preserved for 2-3 years after sealed or vacuum ...

Changes in chlorophyll, anthocyanins and phenolic compounds concentration in fresh–cut onion
The minimal processing of onion is practical and convenient to consumers, eliminating the inconvenience of peeling, cutting, unwanted odour and tearing effect. The study aimed to estimate the levels of chlorophyll, anthocyanins and phenolic compounds in fresh–cut onions, triturated in the form. Onions, white and purple, obtained in Pombal–PB were conducted in the Laboratory of Food ...

CA waste facility eliminates odor complaints for their organic green waste and sludge composting operation
The Problem - The large California facility takes in a great deal of green waste (grass clippings, vegetable & fruit waste, leaves and other vegetation) and food processing sludge. It is all combined and recycled into high grade mulch and compost in their site composting operation. The nature of the waste and the composting process leads to the release of high concentrations of odor - ...
