Abstract

Noni (Morinda citrifolia) is a popular plant in Asian countries and has great potential as pectin source for thickening agents in food products. In general, ethanol has been widely used to precipitate pectin, but the proportion can affect the quality of the product. Therefore, this study aimed to characterize the physicochemical properties of pectin from noni fruit. Extraction was performed using 0.1 N HCl at pH 1.5 and heated at 80°C for 15 min, followed by precipitation with different proportions of 96% ethanol including A (1:1), B (1:2), and C (1:3) v/v, while commercial orange pectin was used as a reference. The results showed that all pectin extracted belonged to the high methoxyl category. The FTIR spectra confirmed the presence of important functional groups including OH-hydroxyl, CH3-saturated aliphatic methyl, C=O carbonyl, and -O- cyclic ether. Furthermore, the crystalline and amorphous structures of noni pectin were confirmed by X-ray diffraction observation. The highest yield was achieved using the proportion of 1:3, followed by 1:2, and 1:1 on a wet basis. The MeO and AUA content of sample B (1:2) were relatively similar to those of the reference. Based on extraction results, noni possesses good characteristics and has the potential for commercial pectin production.

Abstract

This study aimed to evaluate the relationship between the nonvolatile compounds detected in fried shallots and their sensory characteristics. Six shallot varieties were used: Bima Brebes, Bauji, Tajuk, Super Philip, Batu Ijo, and Rubaru. Each variety was assessed using the rate-all-that-apply (RATA) and hedonic rating tests for the taste and aroma of fried shallots. All fried shallots were prepared in a laboratory under homogeneous frying conditions. The chemical compounds in the water extracts of the six fried shallots with molecular weights less than 3 kDa were identified using LC-MS/MS instrument. Additionally, the correlation between the chromatographic peak intensities of the chemical compounds and sensory intensities was examined through multivariate orthogonal partial least squares (OPLS) analysis. The PCA result revealed two distinct groups of samples. Batu Ijo fried shallot, which received the highest overall hedonic score and showed a strong correlation between its fragrant sulfury aroma and savory taste, was categorized separately from the others. Although 18 compounds were identified in fried shallots, a significant correlation was observed only with salty taste, primarily due to glutamyl-phenylalanine, a known kokumi compound.

Abstract

Twenty-four different tauco samples, available as commercial salt-fermented soybean products in Indonesia, were investigated for their microbial counts, proximate composition, as well as FTIR profiles obtained by attenuated total reflectance-fourier transform infrared (FTIR-ATR) instrument. The total and free amino acid profiles by UHPLC, as well as sensory characteristics by taste dilution analysis (TDA) of their ultrafiltration fractions (tauco fractions with molecular weights less than 3 kDa or <3 kDa) were also revealed. The objective of this study was to comprehensively characterize the commercial tauco products in Indonesia through integrated microbial, chemical, and sensory analyses of the products and their low molecular fractions. Tauco samples had total microbes reaching 4 to 9 log CFU/g. Lactic acid bacteria (LAB), which act in the second step of fermentation, were counted at much higher levels in all samples than molds/yeasts, which are important in the first step of fermentation. FTIR profiles of tauco samples are correlated with their protein content. Functional groups correlated with the proximate composition of tauco are identified as follows: protein with carbonyl (C=O) and aliphatic hydrocarbon (C-H), fat with carbonyl (C=O), and carbohydrate with hydroxyl (O-H) groups. Umami was identified as the predominant taste of their ultrafiltration fractions. The amino acid profiles of tauco fractions <3 kDa showed relatively high residual amino acid contents, suggesting abundant peptide content. However, multivariate orthogonal projections to latent structure (OPLS) analysis showed that free amino acids, including glutamic and aspartic acids (umami), glycine and serine (sweet), and phenylalanine and tyrosine (bitter), contributed significantly to the umami characteristic of tauco. This finding shows that free amino acids could contribute to the desirable taste of tauco. This study provides a comprehensive characterization of Indonesian tauco, offering a practical scientific reference for producers to understand product variability, improve fermentation control, and enhance the consistency and value of commercial products.

Abstract

Meats of consumable livestock for humans are commonly from ruminants, such as cows, goats, lambs, buffaloes, etc. The method of slaughtering the livestock at the slaughterhouse mostly applies non-stunning or stunning methods. The stunning method uses electricity, mechanics, and gas. The slaughtering methods influence the meat quality and results. Thus, further meta-analysis is important to provide valid and informative conclusions based on comprehensive investigations about the slaughtering method's effect on ruminant meat quality. The researchers applied the PRISMA diagram and the size of the Standard Mean Difference effect, SMD, with Hedge's formulation as the quantitative synthetical meta-analysis method. The results found that the slaughtering method with stunning and non-stunning methods did not significantly influence some parameters, such as pH, colors (L*, a*, and b*), the water holding capacity, cooking loss, and shear force. However, the methods significantly influenced the drip loss and myofibril fragmentation index parameters with SMD values 0.2, p-values 0.001 to 0.777, and heterogeneity values of 0% to 82.98%.

Abstract

Bawang merah goreng merupakan produk olahan bawang dengan pangsa pasar yang stabil. Saat ini belum ada kriteria mutu baku bawang goreng berdasarkan keinginan konsumen. Pemahaman mutu yang valid diperlukan dalam pengembangan produk terstandar, termasuk pemilihan bahan baku. Bawang goreng tanpa salut, berwarna coklat cerah, utuh, rasa gurih, aroma wangi khas bawang goreng, tidak tengik dan tidak pahit merupakan kriteria yang diinginkan oleh konsumen. Penelitian terhadap 6 varietas unggul bawang merah, yaitu Bima Brebes, Bauji, Super Philip, Rubaru, Tajuk dan Batu Ijo, menunjukkan bahwa penciri fisiko kimia umbi yang unggul sebagai bahan baku bawang merah goreng adalah bobot umbi besar, kadar karbohidrat sedang, kadar total asam amino sedang, dan kadar piruvat tinggi. Varietas Batu Ijo, disamping produktivitasnya tinggi juga menghasilkan bawang goreng dengan krtieria mutu unggul, dibanding 5 varietas lain, termasuk varietas Rubaru atau lebih dikenal sebagai varietas “Sumenep” yang selama ini dikenal sebagai bahan baku bawang goreng.
