Effect of Forage Processor Roll Gap Width and Storage Length on Fermentation Profile, Nutrient Composition, Kernel Processing Score, and Starch Disappearance of Whole-Plant Maize Silage Harvested at Three Different Maturities

Our objective was to assess the effect of forage processor roll gap width and storage length on fermentation, nutrient composition, kernel processing score (KPS), and ruminal in situ starch disappearance (isSD) of whole-plant maize silage harvested at different maturities. Samples from a single maize silage hybrid at three harvest maturities (1/4, 1/2, and 3/4 kernel milk line (early, intermediate, and late, respectively)) processed with two roll gap widths (1 and 3 mm) were collected and stored in quadruplicate vacuum pouches for 0, 30, 120, or 240 d. Lactic acid concentrations were greater, and pH was reduced in early and intermediate maturity silage compared to late maturity silage. Ruminal isSD was greatest for early maturity silage, intermediate for the intermediate maturity silage, and lowest for the late maturity silage, but differences in isSD due to maturity were diminished after prolonged storage. Kernel processing score was greatest in late maturity silage processed through a 1 mm roll gap and lowest in late maturity silage processed through the 3 mm roll gap. For early and intermediate maturity silages, no differences in KPS were observed between the two roll gap widths. Minimal effects of maturity and roll gap width on fatty acids (FA) and amino acids (AA) were observed. Concentrations of total AA decreased as storage length progressed. Results support the premise that the silo is a dynamic system that undergoes numerous chemical changes throughout the storage period.

Aim: The effect of botanical origin and storage conditions on the quality of two Libyan monofloral honey samples (thyme and ziziphus honeys) were assessed during prolonged storage (12 months) at room temperature. Methodology: Physicochemical properties (moisture, viscosity, electrical conductivity, acidity pH, 5-(hydroxymethyl) furfural (HMF), diastase activity, sugars, and color) were monitored. Results: Generally, moisture, acidity, diastatic activity, and color values were significantly higher in thyme honey, whereas viscosity, electrical conductivity, pH, HMF, and sugars content were higher in ziziphus honeys. In comparison with the initial values, viscosity, acidity, and HMF values of all honey samples increased during storage. Storage period and containers did not affect the electrical conductivity and sucrose contents for the two honey types, which were below the stipulated limits. Moisture content, pH, diastatic activity, color (L*), fructose, and glucose content decreased during storage. Honey samples stored in opaque container showed significantly lower changes in all parameters during the storage period compared to those stored in transparent bottles. The results showed that both honey types stored for 12 months at room temperature could be considered safe for human consumption according to maintaining physicochemical parameters.

And Storage

The effect of testing temperature and storage period on the polarization fatigue properties of poly (vinylidene fluoride-trifluoroethylene) (P(VDF–TrFE)) ultrathin film devices were investigated. The experimental results show that, even after stored in air for 150 days, the relative remanent polarization (Pr/Pr(0)) of P(VDF–TrFE) of ultrathin films can keep at a relatively high level of 0.80 at 25 °C and 0.70 at 60 °C. To account for this result, a hydrogen fluoride (HF) formation inhibition mechanism was proposed, which correlated the testing temperature and the storage period with the microstructure of P(VDF–TrFE) molecular chain. Moreover, a theoretical model was constructed to describe the polarization fatigue evolution of P(VDF–TrFE) samples.

Ultra High Temperature

Age gelation is a major quality defect in ultra-high-temperature (UHT) pasteurized milk during extended storage. Changes in plasmin (PL)-induced sedimentation were investigated during storage (23 °C and 37 °C, four weeks) of UHT skim milk treated with PL (2.5, 10, and 15 U/L). The increase in particle size and broadening of the particle size distribution of samples during storage were dependent on the PL concentration, storage period, and storage temperature. Sediment analysis indicated that elevated storage temperature accelerated protein sedimentation. The initial PL concentration was positively correlated with the amount of protein sediment in samples stored at 23 °C for four weeks (r = 0.615; p < 0.01), whereas this correlation was negative in samples stored at 37 °C for the same time (r = −0.358; p < 0.01) due to extensive proteolysis. SDS-PAGE revealed that whey proteins remained soluble over storage at 23 °C for four weeks, but they mostly disappeared from the soluble phase of PL-added samples after two weeks’ storage at 37 °C. Transmission electron micrographs of PL-containing UHT skim milk during storage at different temperatures supported the trend of sediment analysis well. Based on the Fourier transform infrared spectra of UHT skim milk stored at 23 °C for three weeks, PL-induced particle size enlargement was due to protein aggregation and the formation of intermolecular β-sheet structures, which contributed to casein destabilization, leading to sediment formation.

In recent years, developments made to reduce the consequences generated using petroleum products have been strengthening; therefore, biofuels have become a requirement in different countries worldwide with the objective of reducing not only the high levels of current pollution, but also mitigating the effects generated by global warming. Despite the advances that have been made in the field of research on Jatropha, it is still necessary to carry out more detailed studies aimed at achieving a better use of it, identifying the influence of its physical–chemical properties in terms of quality levels, as well as determining its behavior when mixed with palm oil to achieve a biodiesel with better yields, whose impact will be reflected mainly in the environmental field, helping to mitigate the production of greenhouse gases that are produced by petroleum products. Although currently the biofuels sector has made important advances in research, it is necessary to deepen the physical–chemical analyses both in the production and storage processes of biodiesel, so that in the future it can be fully fulfilled with the energy requirements that are currently only achieved with fossil fuels, so it is necessary to direct this research toward the development of new products with improved characteristics, especially when exposed to prolonged storage times and low temperatures.

Microbiological Aspects

The arracacha is an alternative of fresh-cut product; however it can be easily degraded after the processing techniques. The objective of this work was to evaluate the useful life of fresh-cut arracacha submitted to two types of cuts and storage, as well as to evaluate the activity of antioxidant enzymes. The roots were selected, sanitized and submitted to two cut types: cubed and grated. Then they were evaluated at 3 times: 0, 3 and 7 days. The cutting in cubes provided higher quality and lower SOD, CAT and APX activity. However, the grated product presented higher PG activity and lower PPO activity. The microbiological safety and the nutritional value were maintained in both cuts during the whole storage period. The useful life, regarding the physicochemical, nutritional and microbiological aspects, can be established at 7 days under refrigeration for fresh-cut arracacha.
