The study investigated the impact of partial pulp removal (PPR) and fermentation duration (FD) on drying behavior, quality attributes flavor profile cocoa beans. research explored use PPR (ranging from 0% to 100%) at various FDs (0–6 days) as potential pre-conditioning technique enhance time, pH, titratable acidity (TTA), (FQ), index (FI), fermented sun-dried Ghanaian results revealed a significant reduction in time 144 4.3 hours for 6 days beans subjected 0–100% treatment. Nib pH levels...
A new method was developed to detect fish freshness nondestructively by combining electronic nose (E-nose) and tongue (E-tongue) in conjunction with chemometric methods. An E-nose nine metal oxide semiconductor gas sensors a commercial E-tongue were employed this research. Pseudosciaena crocea stored at 4 °C for different days used as experimental samples. Total viable counts (TVC) of the detected conventional method. data analyzed principal component analysis. Three-layer radial basis...
The potential of predicting maturity using total soluble solids (TSS) and identifying organic from inorganic pineapple fruits based on near-infrared (NIR) spectra fingerprints would be beneficial to farmers consumers alike. In this study, a portable NIR spectrometer chemometric techniques were combined simultaneously identify organically produced conventionally ones (thus inorganic) also predict solids. A 90 intact scanned with the while digital refractometer was used measure TSS extracted...
Non-destructive, simple and fast techniques for identifying authentic palm oil those adulterated with Sudan dyes using portable NIR spectroscopy would be very beneficial to West Africa countries the world at large. In this study, a coupled multivariate models were developed detecting adulteration. A total of 520 samples used comprising; 40 together 480 containing (I, II, III, IV 120 each). Multiplicative scatter correction (MSC) preprocessing technique plus Principal component analysis (PCA)...
There are several varieties of mango fruits, and the most important quality indicators for determining maturity pH total soluble solids (TSS). The study examined possibility using a handheld NIR spectrometer (NIRS) with wavelength range 740 nm to 1070 multivariate algorithms in combination smartphone determine mangoes. A 198 intact fruits were scanned spectrometer, while digital refractometer meter used measure TSS from extracted juice. After preprocessing methods, classification models...
African coffee is among the best traded types worldwide, and rapid identification of its geographical origin very important when trading commodity. The study was because it used NIR techniques to geographically differentiate between various provide a supply chain traceability method avoid fraud. In this study, geographic differentiation (bean, roasted, powder) achieved using handheld near-infrared spectroscopy multivariant data processing. Five countries were as origins for collection...
Abstract The objective of this study was to establish quantitative evaluation models for fish microbiological quality analysis based on electronic tongue technique coupled with nonlinear pattern recognition algorithms. Crucian carp stored at 4 C were used. A commercial system employed. total viable counts ( TVC s) samples measured by the classical plating method. Partial least square regression, support vector regression SVR ) and back propagation neural network BP ‐ NN applied comparatively...
Abstract For simultaneous and quantitative prediction of three toxic heavy metal residues (Pb, Cd Hg) in fish, the novel low‐cost colorimetric sensors array was fabricated. Forty eight fish samples (Carassius carassius) retailed Zhenjiang, China, were used. Inductively coupled plasma mass spectrometry employed as reference analytical method. The partial least square regression (PLS) extreme learning machine (ELM) respectively comparatively used for data modeling. Results showed that ELM...
Traceability in the cocoa bean trade is vital to ensuring quality. In this study, a handheld near-infrared (NIR) spectrometer was attempted for rapid and nondestructive regional geographical classification of beans from different locations. Cocoa samples collected seven cocoa-producing regions Ghana (Eastern, Ashanti, Volta, Western South, North, Central, Brong Ahafo) four countries Africa (Uganda, Ivory Coast, Nigeria, Ghana) were used. Among preprocessing techniques employed,...
Near infrared spectroscopy (NIRS) technique as an advance innovative technology has come to stay in food, chemical, pharmaceutical, petrochemical industries. This coupled with the development of chemometric techniques become a powerful, fast, reliable and non-destructive analytical tool for measurement qualitative quantitative properties organic materials. review paper focuses on potential application NIRS determination harmful chemical residues food The results rich studies conducted...
