“…Young’s modulus (YM) is a fundamental measure of the intrinsic stiffness of films, as the higher YM, the higher the stiffness of the material. YM values were between 3.42 and 22.53 MPa; similar results were reported for films made from cassava starch (Méité et al 2022 ), sugar palm ( Arenga pinnata ) starch (Sanyang et al 2015 ) and native jicama starch (Wigati et al 2022 ).…”

Edible films can be formed from different polymeric compounds. The use of starch has gained extra value; because it can be used in combination with plasticizers and lipids, helping to improve mechanical properties. Besides, with the addition of an antimicrobial, the function of these films can be extended. The objective of this research was to evaluate the effect of native cassava starch, beeswax and ethanolic propolis extract (EPE) on the mechanical, thermal and inhibitory properties against the Aspergillus niger fungus. An experimental Box-Behnken design with three factors: cassava starch concentration (2–4%w/v), beeswax (0.5–0.9%w/w) and EPE (1–4%v/w) was used. The films obtained were opaque and with low mechanical properties. EPE concentration affected tensile strength, elongation at break (EB) and Young’s modulus (YM), and cassava starch content only affected EB and YM. In thermal properties, the weight loss was affected by the cassava starch-beeswax interaction, where the most loss occurred at high levels of these factors in the temperature range of 200–360 °C. The films reduced the growth of the Aspergillus niger by 51%, where the beeswax-EPE interaction had a significant positive effect. The characteristics of the developed films suggest that they would be more acceptable as fruit and vegetable coatings.

“…Such results suggest a reinforcement effect of the incorporated nanoparticles containing 0.5 g of Neem oil. [42,43] Mechanistically, the addition of Ecovio-based nanoparticles into PVA leads to the formation of interrelated particle-polymer networks called mesophase, which dissipated the external stresses through particle-particle and particle-polymer friction. [44] For the observed success, 0.5 g of the Neem oil may have formed a core-shell structure-like with sticky shells (due to the leakage of oil from some particles), assisting in the dispersion and wettability of the nanoparticles through the polymer matrix.…”

Nanocompartmentalized films are promising materials for different applications, including biomedical, food, and agricultural fields. Herein, a new concept to prepare such multifunctional films is reported. Aqueous dispersion of nanoparticles based on Ecovio loaded with an active compound (Neem oil as concept proof) is first synthesized by single emulsion–solvent evaporation technique using poly(vinyl alcohol) (PVA) as a surfactant. Then, this dispersion is used to prepare films by casting. The feasibility of upcycling (i.e., deconstruction and reassembly of the films) is obtained through a water‐dependent dynamic phenomenon, where the PVA acts as polymer matrix or surfactant depending on the hydration of the surrounding medium (dry or wet conditions). Nanocompartmentalized films demonstrate improved mechanical performance and reduced transmittance in UVA and UVB spectra, while the nanoparticles (wet condition) show superior stability (more than 9 months). The proposed method allows preparing films with high compartmentalization efficiency that can be used, for instance, as insect‐repellent packaging. Just by adding the films in water, the aqueous dispersion of nanoparticles can be used for controlled release of pesticides, leading to high added value material that fits the circular economy.

“…For livestock, dietary energy can be improved through fat supplementation or concentrate to reduce the negative energy balance, but excess fat supplementation inhibits rumen microbial growth, reduces rumen pH value, and increases subclinical rumen acidity [7]. Therefore, studies and research tended to find a solution to this problem, and among these solutions is the addition of nutritional supplements, including calcium propionate [8]. Propionate is the primary glucose precursor in cattle milk and contributes to the synthesis of oxaloacetate [9,10].…”

This study was conducted at the ruminant research station in Abu Ghraib / livestock research department / agricultural research department / ministry of agriculture. The experiment period from 5/10/2022 to 1/4/2023, and for the production season 2022-2023. In order to study the effect of calcium propionate for different periods to study the difference of these periods in some of the productive characteristics of the Iraqi buffaloes, 15 females of Iraqi milking buffaloes were used, divided into three treatments for each treatment 5 buffaloes aged from 6-7 years, as the first treatment was T1 treatment Control without adding of calcium propionate, the second treatment T2 added 100 g calcium propionate/buffalo, and the third treatment T3 added 150 g calcium propionate/buffalo and for the periods 7 hours before calving, 24 hours after calving and 7 days after calving, calcium propionate was added to the concentrated diet. The results of the study indicate that there is a significant difference (P≤0.05) for milk production within the seventh reading in treatments T2 and T3 g compared with control T1, and a significant difference (P≤0.05) was observed in T2 for milk production within the eighth reading compared with T3 and control T1, and there were significant differences (P≤0.05) for T2 in 1st, 2nd and 3rd months for the percentage of fat compared with treatment T3 and control T1, and the results indicated a significant differences (P≤ 0.05) for treatment T3 in 1st and 3rd months for the percentage of fat compared with T2 and control T1. We conclude that the addition of calcium propionate at a ratio of 100 and 150 gm to buffalo diets during different periods improved the milk production and fat percentage of local female buffaloes.
