The PBAS was obtained by dual modification of native arenga starch through butyrylation using 5% butyric anhydride and crosslinking using 6% a mixture of sodium trimetaphosphate (STMP) and sodium tripolyphosphate (STPP) at 99:1 (w/w). The concentration of the PBAS tested varied at 4.7; 5.0; 5.3; 5.7; 6.0; 6.3; 6.7; 7.0; and 7.3% (w/v) with three replications so that there were 27 experimental units used. The thickness, water holding capacity (WHC), oil holding capacity (OHC), swelling power, solubility, water vapor transmission rate (WVTR), water content, pH, biodegradation and properties of sensory were investigated. Results showed that the thickness, solubility, WVTR and water content of bioplastics increased with the increase in the concentrations of PBAS. On the other hand, WHC and OHC, swelling power, pH, and biodegradation decreased along with the increase in PBAS concentrations. Sensory color of bioplastics increased, while texture, aroma and overall acceptability decreased with the increase in PBAS concentrations. The concentration of PBAS at 7.0% was optimum for the physicochemical and sensory properties of bioplastics as indicated by low WVTR and water content as well as panelist preference on bioplastic texture.

This research was aimed at quantifying technical efficiency of Johor small-scale pineapple agriculturists. Stochastic Frontier Analysis (SFA), a statistical method used to estimate production or cost frontiers, was the preferred method for this purpose. This approach was also used to identify key elements, such as socio-economic characteristics, that influence technical implementation in pineapple farms. A total of 290 pineapple growers participated in the study, and data was collected between 2019 and 2021 during the growing season. The mean observed score of 0.681 is an indication of agriculturists non- maximum efficiency operation activity. However, the inefficiency model showed that aspects such as agricultural experience, extension visits, and participation in workshops significantly reduced inefficiency. The main problem in production points to suboptimal farming applications: agriculturists abstain from using all available agricultural inputs to achieve maximum production.

Since the discovery of the synthesis of saccharin, progressively more non-nutritive sweeteners have been produced and consumed, as they release none or only very small amounts of energy. In this context, traditional synthetic food sweeteners are largely used, because they have a higher sweetener power than most of the sweeteners of natural origin. Yet, due to their potential risks, some of them are being replaced by those obtained from natural origins with high sweetening power, such as thaumatins and neohesperidin DC, or by synthetic sweeteners with an even greater sweetener power, with advantame as the one with the highest sweetening power. Yet, numerous side effects of synthetic sweeteners have been reported (namely, stomach and liver problems, allergic reactions, nausea, vomiting, changes in behaviour, cognitive problems, genotoxicity and carcinogenic effects), whereas those naturally derived seem to have less important health problems associated. Moreover, some sweeteners of natural origin, such as polyols, have a low sweetening power, which makes them less effective, but have other functions in food processing. To further understand the implications of using synthetic and natural-derived food sweeteners, this review aims to provide a synoptical approach on chemical characteristics, properties, uses and side effects of those which are currently allowed and applied during food processing mostly considering the authorized sweeteners in European Union.

Through LC/MS analysis, the algal extract's phenolic composition was determined by its abundance in quinic acid, gallic acid, kaempferol and luteolin. The concentration of leaf proline increased while the biomass production, chlorophyll fluorescence, SPAD index and mineral composition all decreased as a result of salt stress. The salt-stress tolerance mechanism in lettuce involved the expression of genes that encode antioxidant enzymes, including LsSOD, LsCAT, and LsAPX, in both stressed and control plants, which demonstrates their important roles. The findings revealed that plants that were treated with marine algal extract had a greater ability to handle salt challenge, as evidenced by a significant (p < 0.05) increase in plant growth, SPAD index, Fv/Fm ratio, a better nutritional status in addinto a better osmoprotection against salt stress. Malondialdehyde level, Hydrogen peroxide and stability index levels were significantly decreased. Furthermore, the antioxidant system saw a significant improvement, as demonstrated by the increased activity of catalase (CAT), superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) under moderate stress conditions (50mM) and more abundant LsCAT transcripts in the stressed plants. Overall, our findings indicate that marine algal extract appears to be an effective biostimulant product for treating lettuce under saline conditions.

This study aimed to characterize the ACCD and nitrogenase genes of PCM8 strain. The acdS gene was obtained from the results of Whole Genomic Sequencing analyis, while the nifH gene was obtained by PCR. The characterization of both of the genes was carried out by means of in-silico analysis. WGS annotation analysis, showed that the acdS gene of PCM8 was located at the locus 19090 of genomic DNA and contains 978 nucleotides. In silico analysis of both acdS and nifH gene products showed that the ACCD enzyme of PCM8 had 325 amino acids, with molecular weight of 34.95 kDa, while nitrogenase as represented by nifH subunit product consist of 96 amino acids with molecular weight of 93.98 kDa, respectively.
