CO2 Removal and Stripping Column Ventilation Rate at Bell Aquaculture
Monitoring and controlling CO2 level in Recirculating Aquaculture Systems (RAS) is crucial not only for fish health but it is used increasingly for efficient management. Under supervision of Steve Summerfelt, a joint project has studied costs savings with optimizing ventilation based on CO2 continuous monitoring. The CO2 probe used in that project came from ...

Technology that is making plants grow bigger and better
This article outlines new and improved technology that is enabling growers to increase their yield and output of their crops. The technology includes carbon dioxide (CO2) monitors and controllers, soil moisture sensors, plant based sensors such as sap flow and dendrometers, and nutrient sensors such as EC and TDS sensors. All of the equipment can be automated and data sent to your smart phone or ...

The Use of CO2 Monitoring in the Fruit Ripening and Conservation
Nothing says summer like biting into a juicy, perfectly ripe strawberry. A bright red package, with a soft, sweet aroma and a firm texture are all the signatures that the fruit is ripe and ready to be eaten. However, with just a day or two more, a fruit that may have been a delightful treat can become a mushy, flavourless mess and home to mould. Fruit ripening gas can play a big part in ensuring ...

From Farm to Market: Fruit Ripening
Fruit has a brief window where it is perfectly ripe. If farmers waited until every piece of fruit was ripe before harvesting, farming would be more labor-intensive as farmers rushed to pick ripe fruits. Prices might crash due to a short-term glut of fruit on the market. To ensure a steady supply and demand, keep prices competitive, and reduce food waste, farmers use artificial ripening ...

Winemaking - A Must Read
BackgroundThe art and science of winemaking have been around for thousands of years. Winemakers rely on their instincts, palettes, and a thorough knowledge of the nuances involved in every stage of the winemaking process as they strive to achieve the flavors and qualities that they desire.Even a cursory overview of certain elements of the process underscores the critical role played by gases…from ...

Soil CO2 Flux Measurements -- Addressing Spatial Variability: Determining the Number of Readings Required
Soils can be highly variable in terms of CO2 flux values. Even at a seemingly uniform site, the soil CO2 flux might range from 2 μmol/m2/s at one location to over 4 mol/m2/s just a few meters away. To obtain reliable site mean flux values, it is important to determine how many readings might be required so that time and resources can be properly allocated before starting an investigation. In ...

When Freshness Counts – Modified Atmosphere Packaging
Centuries ago, merchants and shippers would place a lit candle inside barrels used to store biscuits before closing the lid. The idea was that the candle flame would deplete the oxygen inside the barrel to help keep the biscuits from spoiling. These days, the candle flame has been replaced by processes called Modified Atmosphere Packaging (MAP), which can be either active or passive. By altering ...

Roots to Recreation: Cannabis Legalization Promotes Grow Room Expansion
Criminalization of cannabis cultivation and consumption in the United States began with prohibition by certain states in the early 20th century (between 1911 and 1933, some 29 states banned the cultivation and/or use of cannabis), with the first significant nationwide federal restrictions implemented under the Marihuana Tax Act of 1937. More recently, just as the states instituted the first ...

Modified Atmosphere Packaging Gets a New QA Tool for Fresh-Cut Produce
Measuring only CO2 and O2 in Modified Atmosphere Packaging for produce leaves out an important key marker of produce freshness: Ethylene (C2H4). C2H4 production is a natural part of the plant life cycle, a complex hormone that varies not only between species, but from crop to crop of the same species. C2H4 has been called the plant “death hormone”, because as part of the natural ...

Evaluating the models of stomatal conductance response to humidity in a tropical rain forest of Xishuangbanna, southwest China
The ecosystem-level fluxes of water vapour and carbon dioxide were measured from 2003 to 2006 at a tropical rain forest in Xishuangbanna, southwest China, using the eddy covariance (EC) technique. These flux measurements allowed the canopy-level evaluation of stomatal conductance (g) response to humidity models. The results showed that both the BWB model and the Leuning model discussed here ...

The Role of CO₂ Measurement in Wine Production
Fermentation, the chemical process that uses yeast to convert sugars to ethanol, is at the heart of the wine production process and requires accurate CO₂ measurement to ensure quality wines. Temperatures and conditions in wineries are very carefully controlled to ensure that fermentation does not occur too fast, distorting the flavour and alcohol content of the wine. The type of yeast used ...

Creating Gaseous Micro Environments for Packaged Produce to Maintain the Quality of Fresh Fruits and Vegetables
Often we are unaware of the long and arduous journey food takes before reaching our plate. Retaining food freshness is in part due to creating gaseous micro environments that ensure the preservation of food quality. In the United States, it is estimated that food typically travels between 1500 and 2500 miles1 between the farms where it is produced and the dinner table where it is ultimately ...

The Importance of Water Quality in Fish Farming
Due to the increasing global demand for fish as a source of food, around half of the world’s fish supply is now farmed artificially rather than caught through capture fisheries in natural environments. Aquaculture has been the fastest growing sector of the global food industry since the 1970s, and has predominately taken place in the Asia-Pacific region. Water quality management in ...

Improving Cereal Storage Facilities with Gas Sensing
Storage of cereal crops and other foodstuffs is an essential part of ensuring a sustainable and robust food supply. Cereal crops are typically harvested between mid-July to mid-September but with careful storage can be kept for periods longer than a year.1 Successful storage of cereals involves the balance of a variety of environmental conditions to ensure the maintenance of quality and the ...

The Effect of COVID-19 ‘Panic Buying’ on Food Supply Chains and the Requirement for Gas Sensing
IntroductionCOVID-19 concerns around the world have sparked widespread panic buying and empty supermarket shelves. Large-scale lock-downs to contain the outbreak have further hurt the supply of manpower and disrupted supply chains in the agricultural industry.The United Nations’ Food and Agriculture Organization have said that the world risks a ‘looming food crisis’ if we do not take fast ...

CO2 Shortage in the UK set to Disrupt Food Supplies
What is Carbon Dioxide and how is it used in the Food and Drink Industry?Carbon Dioxide (CO2) is a chemical compound that is an odourless and colourless gas at room temperature. It enters the atmosphere through the exhalation of organisms and the combustion of matter as a byproduct of industrial production. CO2 has a wide range of uses across many different industries, in particular the food and ...

Gas Monitoring in Frozen and Dried Food Storage
There are many different approaches to food preservation for extending the lifetimes of perishable goods. From pickling, salting, canning or jellying, all of these approaches have different effects on the properties of the preserved produce and are suitable for different types of food. Two of the most widely used methods for food preservation are freezing and dried food storage. The low ...
