Safety Assessment Of Hydroponic Closed System, Adwoa S. Dankwa May 2019

Safety Assessment Of Hydroponic Closed System, Adwoa S. Dankwa

Electronic Theses and Dissertations

The hydroponic system is an increasing sector for horticultural production. It is used mostly for fruit and vegetable production. Lettuce (Lactuca sativa) is one of the most cultivated types of produce in the hydroponic system. It runs on nutrient solution and in some cases substrates. Water serves as the backbone for hydroponic production, mainly utilized for nutrient solution preparation. Substrates are sometimes added to provide support for plants root systems. Selection of substrate depends on the type of crop and the availability of the substrate. A good substrate should be able to balance the oxygen - water ratio around the root ...


Effects Of Salt Concentration On The Physicochemical Properties And Microbial Safety Of Spontaneously Fermented Cabbage, Surbhi Khanna May 2019

Effects Of Salt Concentration On The Physicochemical Properties And Microbial Safety Of Spontaneously Fermented Cabbage, Surbhi Khanna

Electronic Theses and Dissertations

Fermented foods, including sauerkraut, have gained consumer popularity due to an increased awareness of reported health benefits associated with probiotics. Sauerkraut is typically produced at 2−3% salt concentrations or higher, which helps to reduce the growth of pathogenic and spoilage microorganisms. The FDA has recently issued guidance to the food industry to voluntarily reduce sodium in products due to health concerns associated with high sodium consumption. Therefore, interest in lower salt fermented foods may increase. However, information on quality and safety of lower sodium sauerkraut is limited. Two separate studies were conducted to evaluate the physicochemical properties and quality ...
