Dietary Fiber and Dyslipidemia

Fibers are abundantly found in vegetables, fruit, beans, cereals, seeds, and tubers. Beans and seeds, alongside prevailing as both of the fiber sources, are the sources of vegetable protein as well. Whereas tubers are a carbohydrate source, which people deem as a staple food. Fiber intake in diets, particularly soluble fibers, has the ability to produce gel in the intestines, inhibiting glucose and cholesterol absorption. Dietary fibers have the ability to bind bile salts in the digestive tract, and disturbed bile reabsorption will stimulate bile synthesis in the liver. Dyslipidemia has a significant role in systemic responses and inflammation in adipose tissues. Inflammation can increase intestinal permeability and adipose tissues. Dyslipidemic management is carried out by altering lifestyles, intervening in suitable diets to reduce LDL levels, and increasing HDL levels. The degree of compliance with diet interventions is seminal to ensure successful dyslipidemic management.

Carcass and meat quality in growing-finishing pigs fed diets with plant-based protein sources alternative to genetically modified soybean meal

The objective of this study was to evaluate carcass and meat quality in growing-finishing pigs fed diets with different vegetable protein sources. It was found that partial (50% in grower diets) and complete (100% in finisher diets) replacement of protein from genetically modified soybean meal (GM-SBM) with protein from 00-rapeseed meal (00-RSM), alone or in combination with protein from faba bean seeds (FB) cv. ‘Albus’, yellow lupine seeds (YL) cv. ‘Taper’ or corn DDGS, had no significant effect on carcass quality characteristics or the chemical composition of meat. In all groups, meat samples were characterized by color typical of pork, high water-holding capacity and low pH values. A sensory analysis of the eating quality attributes of meat revealed that they were highly satisfactory; only aroma intensity was affected by the experimental factor. The study demonstrated that growing-finishing pigs can be fed complete diets containing the analyzed vegetable protein sources alternative to GM-SBM without compromising carcass or meat quality.

Perilaku makan sebelum dan selama pandemi covid-19 pada kelompok remaja dan dewasa di Indonesia

The COVID-19 pandemic impacts lifestyle changes, one of which is the eating behavior of people. The research aims to examine changes in eating behavior before and during the COVID-19 pandemic among adolescents and adult groups in Indonesia. A cross-sectional study on 563 subjects, with the subject's inclusion criteria, namely living in Indonesia, aged 12-55 years, willing to participate in the research by filling in informed consent and filling out a questionnaire via an online google form. The data obtained were grouped based on variables before and after the pandemic, then tested the normality of the data. Bivariate analysis used the Wilcoxon text because the data were not normally distributed. As a result, there was an increase in the subject's breakfast habits and frequency of eating. Subjects experienced changes in eating habits, namely an increase in the frequency, variety, and portion of consumption of animal protein, vegetable protein, vegetables, and fruit between before and during the COVID-19 pandemic (p <0,001). In addition, the habit of consuming fluids, supplements, and spices also experienced a significant increase, while the pattern of snacking decreased between before and during the pandemic (p <0,001). In conclusion, there were differences in eating behavior: breakfast habits, dietary variations, consumption of animal and vegetable protein, vegetables, fruits, fluids, supplements, spices, and snacking patterns outside the home between before and during the pandemic in the subject

Characteristics of Beef Patties Substituted by Different Levels of Textured Vegetable Protein and Taste Traits Assessed by Electronic Tongue System

The main objective of this study was to incorporate soy-based textured vegetable protein (TVP) into beef patties in different quantities (10–40%) and compare various characteristics of these innovative formulations with a regular beef patty as a control. Incorporation of 10–40% TVP resulted in significantly lower (p < 0.05) moisture and fat contents, while higher crude fiber contents were detected compared to beef as the control. In addition, cooked patties showed higher pH levels (p < 0.05), with color coordinates expressing lighter, yellowish, and slightly redder indices than raw patties. Similarly, a plant protein that includes TVP minimizes (p < 0.05) WHC (water holding capacity), both RW% (release water) and CL% (cooking loss). Furthermore, hardness, cohesiveness, and thickness were reduced significantly (p < 0.05), while gumminess and chewiness increased (p < 0.05) considerably with the substitution of TVP (10–40%) compared to the control. Patties made without TVP received higher scores for sourness, bitterness, umami, and richness than the rest of the formulations. However, a higher tendency was detected for sourness, astringency, umami, and saltiness values with increasing additions of TVP. Nevertheless, hierarchical clustering revealed that the largest group of fatty acid profiles, including palmitoleic acid (C16:1), stearic acid (C18:0), and palmitic acid (C16:0), was slightly reduced with the addition of TVP, while arachidic acid (C20:0), lauric acid (C12:0), and oleic acid (C18:1) increased moderately with increasing levels of TVP. Meanwhile, the second-largest cluster that included linoleic acid (C18:2), arachidonic acid (C20:4), and linolenic acid (C18:3) increased enormously with higher levels of TVP incorporation. Taken together, it is suggested that incorporation of TVP up to 10–40% in beef patties shows promising results.

1H-NMR Metabolomics as a Tool for Winemaking Monitoring

The chemical composition of wine is known to be influenced by multiple factors including some viticulture practices and winemaking processes. 1H-NMR metabolomics has been successfully applied to the study of wine authenticity. In the present study, 1H-NMR metabolomics in combination with multivariate analysis was applied to investigate the effects of grape maturity and enzyme and fining treatments on Cabernet Sauvignon wines. A total of forty wine metabolites were quantified. Three different stages of maturity were studied (under-maturity, maturity and over-maturity). Enzyme treatments were carried out using two pectolytic enzymes (E1 and E2). Finally, two proteinaceous fining treatments were compared (vegetable protein, fining F1; pea protein and PVPP, fining F2). The results show a clear difference between the three stages of maturity, with an impact on different classes of metabolites including amino acids, organic acids, sugars, phenolic compounds, alcohols and esters. A clear separation between enzymes E1 and E2 was observed. Both fining agents had a significant effect on metabolite concentrations. The results demonstrate that 1H-NMR metabolomics provides a fast and robust approach to study the effect of winemaking processes on wine metabolites. These results support the interest to pursue the development of 1H-NMR metabolomics to investigate the effects of winemaking on wine quality.
