“…There are other examples of the use of this test temperature on other non‐food fluids (e.g.,: neat biodiesel and biodiesel/diesel fuel blends). As demonstrated in our previous research [ 20 ] and here confirmed, there is a good correlation between TBHQ residual concentration and Rancimat Induction Time and this represents a further demonstration of the suitability of the adopted strategy. Obviously, the RIT is not the only parameter to be controlled.…”

“…A drop in viscosity represents the effect of oil degradation toward low molecular weight molecules and the development of acid products, while an increase in viscosity is a clear evidence of a polymerization effect. All these subjects have been hightlighted during the already cited research [20 . ]…”

“…[ 16–18 ] Many studies have been carried out to investigate the sustainability of hydraulic fluids developed from oil crops, such as crambe, [ 19,20 ] rapeseed, [ 21,22 ] soybean, [ 23 ] and high oleic sunflower. [ 24,25 ] In recent years, there has been a growing interest in the use of olive pomace oil for biodiesel production as replacement of fossil diesel fuel, [ 26–28 ] but the use of this by‐product of the olive oil production chain as hydraulic fluid or lubricant for agricultural applications has never been proposed until now.…”

“…[ 29 ] In this study, the pomace oil was added with a common food‐grade antioxidant ( tert‐ butylhydroquinone, TBHQ, E319). In this respect, the results of our previous experiences on Crambe abyssinica oil [ 20 ] and on Cartamus tinctorius oil (unpublished data) showed that, under heavy duty service conditions, a low level of additive (namely 250 mg per kg) is not sufficient to ensure adequate oil protection for an acceptable time interval.…”

This paper aims at investigating the possibility of replacing conventional hydraulic fluids with refined olive pomace oil added with a common food grade antioxidant, as hydraulic fluid for agricultural machinery. The fluid efficiency test is carried out using an experimental test rig based on a hydraulic system designed to apply severe work cycles (pressure values up to 40 MPa; temperatures up to 100 °C) to small oil volumes with the aim of strongly accelerating the ageing of the tested fluid. The fluid, added with 2 g kg−1 of antioxidant, apparently does not undergo any changes in chemical‐physical properties and maintains stable the technical performance of the test equipment during 530 h work cycle. This research has four different goals: i) to contribute to the circular economy, by using olive oil byproducts in agricultural environment; ii) to contribute to the reduction of environmental contamination by substituting petroleum products with natural biodegradable ones; iii) to contribute to avoid the presence of mineral products (such as saturated hydrocarbons, which could accumulate in human organs, and aromatic hydrocarbons, which are potentially genotoxic), as a residue in food products and in vegetable oils. iv) to identify alternative market possibilities for such a by‐product. Practical applications: The results of the study seem to indicate the possibility of using the olive pomace oil as hydraulic fluid, for example, in agricultural machinery, opening new market perspectives which would increase its added value.

“…Among the plants known to contain bioactive compounds with antimicrobial and antioxidant activity, the Brassicaceae family includes species that historically belong to the human diet, and are widely cultivated as important oilseed crops. Vegetable oils, in particular those from Brassica oilseeds, are well known for their potential applications in green chemistry, including their use as hydraulic fluids, biolubricants, and cosmetics [33]. Biomolecules produced from Brassica oilseed co-products, namely defatted seed meals (DSMs), can be applied in food and feed industries and as sustainable tools for agriculture, thus representing an innovative solution for the agricultural and processing phases [34][35][36][37].…”

Seed Meals from Brassica nigra and Eruca sativa Control Artificial Nosema ceranae Infections in Apis mellifera

Nosema ceranae is a widespread parasite responsible for nosemosis Type C in Apis mellifera honey bees, reducing colony survival. The antibiotic fumagillin is the only commercial treatment available, but concerns are emerging about its persistence, safety, and pathogen resistance. The use of natural substances from Brassicaceae defatted seed meals (DSMs) with known antimicrobial and antioxidant properties was explored. Artificially infected bees were fed for 8 days with candies enriched with two concentrations, 2% and 4%, of two DSMs from Brassica nigra and Eruca sativa, containing a known amount of different glucosinolates (GSLs). The food palatability, GSL intake, bee survival, and treatment effects on N. ceranae spore counts were evaluated. Food consumption was higher for the two 2% DSM patties, for both B. nigra and E. sativa, but the GSL intake did not increase by increasing DSM to 4%, due to the resulting lower palatability. The 2% B. nigra patty decreased the bee mortality, while the higher concentration had a toxic effect. The N. ceranae control was significant for all formulates with respect to the untreated control (312,192.6 +/− 14,443.4 s.e.), and was higher for 4% B. nigra (120,366.3 +/− 13,307.1 s.e.). GSL hydrolysis products, the isothiocyanates, were detected and quantified in bee gut tissues. Brassicaceae DSMs showed promising results for their nutraceutical and protective effects on bees artificially infected with N. ceranae spores at the laboratory level. Trials in the field should confirm these results.
