Article Abstract
This paper presents the development of a PC-based microwave five-port reflectometer for the determination of moisture content in oil palm fruits. The reflectometer was designed to measure both the magnitude and phase of the reflection coefficient of any passive microwave device. The stand-alone reflectometer consists of a PC, a microwave source, diode detectors and an analog to digital converter. All the measurement and data acquisition were done using Agilent VEE graphical programming software. The relectometer can be used with any reflection based microwave sensor. In this work, the application of the reflectometer as a useful instrument to determine the moisture content in oil palm fruits using monopole and coaxial sensors was demonstrated. Calibration equations between reflection coefficients and moisture content have been established for both sensors. The equation based on phase measurement of monopole sensor was found to be accurate within 5% in predicting moisture content in the fruits when compared to the conventional oven drying method.

The aim of this study was to investigate the effects of ultrasound at two different frequencies, namely 30 kHz and 42 kHz, on various aspects of industrial Iranian honey, including its physical, biochemical, antioxidant and antimicrobial properties. Samples were subjected to ultrasound treatment at 30 kHz or 42 kHz for a duration of 1, 5 or 10 minutes at temperatures of 20 °C or 45 °C, respectively. The following parameters were then evaluated on days 1, 30, 90, and 180: HMF content, pH, acidity, proline concentration, total number of aerobic mesophilic bacteria, diastase activity, moisture content, sucrose concentration, fructose concentration, glucose concentration, fructose- glucose ratio, ABTS (antioxidant activity) content, number of osmophiles, phenol concentration, reducing sugar concentration and total sugar concentration.

Article Synopsis
- GPE extract from traditional Chinese medicine shows promise in enhancing growth performance and meat quality in ducks.
- The study involved 480 ducks receiving different levels of GPE over 7 weeks, with the highest dosage (600 mg/kg) leading to significant health benefits.
- Findings indicated improvements in serum antioxidant capacity, immune function, and meat characteristics like moisture content and tenderness, suggesting GPE could be a viable alternative to antibiotics in poultry farming.
Evaluation of Energy Utilisation Efficiencies of Digestible Macronutrients in Juvenile Malabar Snapper () Reveals High Protein Requirement for Optimal Growth Using Both Factorial and Multifactorial Approaches.

Malabar snapper () is an economically important marine fish throughout the Indo-Pacific, with an emerging aquaculture industry. Although generic marine feeds are available for production, these are not optimised for this species. Understanding energy utilisation and balance can provide insight into suitable macronutrient profiles for new species to provide a baseline for future development.
