Significant differences were measured for malic acid, total phenolic content (TPC), and total antioxidant activity. The highest TPC was measured in BD and control samples (0.677 and 0.672 mg GAE g−1, respectively), and the lowest in CON samples (0.511 mg GAE g−1). Antioxidant activity was positively correlated with TPC (r2 = 0.6187) and ranged from 0.823 μM TE g−1 FW to 1.270 μM TE g−1 FW in CON and BD samples, respectively, whereas total sugar content ranged from 21.03 g kg−1 FW (CON) to 31.58 g kg−1 FW (BD).

This research demonstrates the basic elements of a prototype automated orchard sprayer which delivers pesticide spray selectively with respect to the characteristics of the targets. The density of an apple tree canopy was detected by PROWAVE 400EP250 ultrasound sensors controlled by a Cypress PSOC CY8C29466 microcontroller. The ultrasound signal was processed with an embedded computer built around a LPC1343 microcontroller and fed in real time to electro-magnetic valves which open/close spraying nozzles in relation to the canopy structure. The analysis focuses on the detection of appropriate thresholds on 15 cm ultrasound bands, which correspond to maximal response to tree density, and this was selected for accurate spraying guidance. Evaluationof the system was performed in an apple orchard by detecting deposits of tartrazine dye (TD) on apple leaves. The employment of programmable microcontrollers and electro-magnetic valves decreased the amountof spray delivered by up to 48.15%. In contrast, the reduction of TD wasonly up to 37.7% at some positions within the tree crown and 65.1% in the gaps between trees. For all these reasons, this concept of precise orchard spraying can contribute to a reduction of costs and environmental pollution, while obtaining similar or even better leaf deposits.

The capability of near infrared (NIR) spectroscopy was examined for the purposes of regular quality control in case of traditional Slovenian dry-cured ham “Kraški pršut”. Moisture, salt, protein, non-protein nitrogen, intramuscular fat content and free amino acids were determined in biceps femoris muscle (n=135). The samples were scanned (wavelength range from 400 to 2500 nm) with spectrophotometer NIR System model 6500 (Silver Spring, MD, USA), and data analysed using WinISI II software. The quality of predictive models was assessed based on cross-validation determination coefficients (RCV) and residual predictive deviation (RPD). Results were excellent for salt content and the percentage of salt in moisture or dry matter (RCV)0.90, RPD)3.0), satisfactory for moisture, non-protein nitrogen and intramuscular fat content (RCV=0.80−0.90, RPD=2.2−2.8), and moderate for other constituents (RCV=0.65−0.80, RPD=1.7−2.0). Calibrations for free amino acids yielded RCV from 0.50 to 0.85 and RPD from 1.4 to 2.5. Based on our results, NIR spectroscopy can successfully replace chemical methods in quality control of dry-cured ham.

A multi-criteria model for a qualitative assessment of the production and marketing of local food products (LFP) from mountain areas has been developed by applying the DEX method. The development of the model was carried out and finally applied to ten local food products. The results were given in the form of a qualitative final assessment of both the production and marketing phases. By applying a plus–minus-1 analysis, the influence of various attributes on the final assessment of the LFP was examined. The main bottlenecks in the production and marketing processes were found. A sensitivity test was used to explain the influence of production and marketing on the final assessment. The results give clear directions as to which of the main attributes must be changed/improved or further developed to enable the successful promotion of local food products, which would give rise to an improved economy in mountain areas.

This review presents the aaplications of intestinal cell models of human and pig origin in food and nutritional sciences and highlights their potential as in vitro platforms for preclinical research. Intestinal cell models are used in studies of bioavailability, adsorption and transport in nutritional or toxicological settings, allergic effects of food components, as well as probiotics and/or host-pathogen gut interactions. In addition, this review discusses the advantages of using specialized and functional cell models over generic cancer-derived cell lines.
