A nondestructive optical method for determining the total solids content (TSC) and soluble solids content (SSC) of fresh whole prune (Prunus domestica L. ‘French’) was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the TSC (r /0. 98, SEP /0.80% FW) and SSC (r /0. 96, SEP / 1.02%) of prunes. A low cost ($250

Objectives: The overall objective of the project was to develop a novel light-based sensing technique to assess internal quality (firmness and sugar content or soluble solids content) of apples. Specific objectives were to: 1. Investigate a new sensing method, using hyperspectral and multispectral imaging, for quantifying the absorption and scattering properties of apple fruit; 2. Develop mathe...

Pears (Pyrus communis L. cv. ‘Rocha’) were exposed to air or controlled atmosphere (CA) containing various concentrations of CO2: 0, 0.5 and 5 kPa, all with 2 kPa O2. After 4 months of storage at 2 ◦C, the fruits were transferred to air at room temperature, and assessed in terms of soluble solids, titratable acidity, pH, incidence of brown heart and flesh browning, phenolic content, vitamin C c...

The influence of sludge properties in SMEBR and conventional MBR pilot systems on membrane fouling was investigated. Generated data were analyzed using statistical analysis Pearson's product momentum correlation coefficient (r(p)). Analysis showed that TMP had strong direct (r(p)=0.9182) and inverse (r(p)=-0.9205) correlations to mean particle size diameter in MBR and SMEBR, respectively. TMP i...

As environmental regulations become more stringent, environmentally sound waste management and disposal are becoming increasingly more important in all aquaculture operations. One of the primary water quality parameters of concern is the suspended solids concentration in the discharged effluent. For example, EPA initially considered the establishment of numerical limitations for only one single...

The effects of climate change on the taste and textural attributes of foods remain largely unknown, despite much public interest. On the basis of 30-40 years of records, we provide evidence that the taste and textural attributes of apples have changed as a result of recent global warming. Decreases in both acid concentration, fruit firmness and watercore development were observed regardless of ...

For effective water quality management and policy development, spatial variability in the mean concentrations dynamics of riverine needs to be understood. Using chemistry (calcium, electrical conductivity, nitrate-nitrite, soluble reactive phosphorus, total nitrogen, phosphorus suspended solids) data for up 578 locations across Australian continent, we assessed impact climate zones (arid, Medit...
