Functional Components

Nuts, besides favourable fatty acid and nutrient profile, possess certain bioactive/functional compounds, which elicit several health benefits. Premium mutton nuggets with improved nutritional profile were developed by reducing the traditionally added animal fat in emulsion with the incorporation of almond paste. In order to substitute added fat by nut-based fat, standardised almond paste with 50% lipids in its proximate were explored at three levels (10%, 15% and 20%) to determine the optimum level of its incorporation. The extra lipid content of almond paste was adjusted by replacing lean on constant weight basis. The premium product was further analysed and compared with traditional product for detailed product profile, which included lipid profile, calorific value, dietary fibre, antioxidant activity and texture profile. Based on physico-chemical and sensory scores, the optimum level of incorporation for almond paste was adjudged as 15%. Developed premium mutton nuggets had significantly less (P < 0.05) cholesterol content, increased dietary fibre, enhanced antioxidant activity and acceptable texture profile. Thus, it was concluded that functional components of almond can be very well incorporated in the conventional process to develop a superior product.

AbstractThe study aimed to determine the effect of pea protein powder on the pasting behavior and physico-chemical properties including the composition of amino and fatty acids of gluten-free bread with low-carbohydrate content. The control bread recipe was based on buckwheat flour (50 g) and flaxseed flour (50 g) as main flours. Additionally, the improving additives for this control bread such as psyllium husk (4 g), potato fiber (2 g), and guar gum (2 g) were used. The mixture of base flour was supplemented with the addition of pea protein powder (PPP) in the amount ranging from 5 to 25%. The results of Visco analyzes measured by RVA apparatus showed that the addition of 10% PPP to the control bread did not significantly differentiate peak viscosity and pasting temperature which was at the level 3115 cP and 3149 cP and 50 °C, respectively. Supplementation of low-carbohydrate bread with 10% of PPP was acceptable and significantly increased the content of all analyzed amino acids, as well as the amount of α-linolenic acid concerning the control bread. The lowest value of chemical score was observed for leucine. The EAAI (essential amino acid index) value increased from 34 to 40 when the optimal protein supplement was added. The developed gluten-free, low-carbohydrate, and high protein bread was characterized by contents of carbohydrate of 16.9%, protein of 17.1%, fiber of 13.7%, fat of 3.3% and its calorific value was 194 kcal/100 g.

AbstractGarlic oil in water nanoemulsion was resulted through subcritical water method (temperature of 120 °C and pressure of 1.5 bar, for 2 h), using aponin, as emulsifier. Based on the prepared garlic oil nanoemulsion, astaxanthin–garlic oil nanoemulsions were prepared using spontaneous microemulsification technique. Response surface methodology was employed to evaluate the effects of independent variables namely, amount of garlic oil nanoemulsion (1–9 mL) and amount of provided astaxanthin powder (1–9 g) on particle size and polydispersity index (PDI) of the resulted nanoemulsions. Results of optimization indicated that well dispersed and spherical nanodroplets were formed in the nanoemulsions with minimum particle size (76 nm) and polydispersity index (PDI, 0.358) and maximum zeta potential value (−8.01 mV), using garlic oil nanoemulsion amount of 8.27 mL and 4.15 g of astaxanthin powder. Strong antioxidant activity (>100%) of the prepared astaxanthin–garlic oil nanoemulsion, using obtained optimum amounts of the components, could be related to the highest antioxidant activity of the colloidal astaxanthin (>100%) as compared to that of the garlic oil nanoemulsion (16.4%). However, higher bactericidal activity of the resulted nanoemulsion against Escherichia coli and Staphylococcus aureus, were related to the main sulfur bioactive components of the garlic oil in which their main functional groups were detected by Fourier transform-infrared spectroscopy.

The Difference

Agricultural and forest residues are potential sources of renewable energy in various countries. However, the difference in characteristics of biomass resources presents challenges for energy conversion processes which often require feedstocks that are physically and chemically consistent. This study presented a complete and comprehensive database of characteristics of a wide range of agricultural and forest residues. Moisture, bulk density, calorific value, proximate and elemental compositions, as well as cellulose, hemicellulose, and lignin compositions of a wide range of biomass residues were analyzed. The major impacts of the variability in biomass compositions to biochemical and thermochemical processes were also discussed.

Papaya (Carica papaya L) is some fruit rich in antioxidants and an important source for obtaining bioactive compounds. Its production, worldwide for the year 2017, was 13.3 million tons. In its industrial processing is obtained approximately between 15 and 20%, in relation to the weight of the fruit, of husks or epicarp, which are likely to be used in order to obtain organic compounds such as carotenoids and polyphenols, among others, contributing, in addition, to mitigate the effects on the environment, since generally, these shells are thrown into landfills of solid waste, generating serious problems of environmental pollution. The objective of this research was to characterize physicochemically the carotenoid pigments obtained from the papaya epicarp. A papaya epicarp flour was processed and it was determined, both in it and in the fresh epicarp, pH, titratable acidity, moisture content and dry matter. Likewise, the carotenoid content, the antioxidant activity and the content of phenolic compounds were determined. The results showed high values for physicochemical parameters. The content of carotenoid compounds for the fractions of β-carotene, α-carotene, β-cryptoxanthin, Zeaxanthin and lycopene ranged between 8,587 and 4,070 mg/100g of epicarp, with the highest value corresponding to β-cryptoxanthin and the lowest value the lycopene fraction. The antioxidant activity, expressed as inhibition of the DPPH radical, gave a value of 58.77 ± 3.038 IC50 mg/ml. The content of phenolic compounds measured in mg of gallic acid equivalents/g gave a result of 24.948 ± 0.728. The data obtained allow us to conclude that said flour can be used as a source of bioactive compounds and natural pigments both in the food industry and in the technical and pharmaceutical industries.

Wiyoto H, Andriani MAM, Parnanto NHR. 2011. Study of antioxidant activity and anti-cholesterol content on red yeast rice with substrates variation (rice, corn and dried cassava). Biofarmasi 9: 38-44. Red yeast rice is one of fermented rice product by Monascus purpureus. Traditionally, the substrate used to produce red yeast rice is rice. Usually, the rice with high amylose content is proper to produce red yeast rice than low amylose. The other substrates that be used to produce red yeast rice are corn and dried cassava. The purposes of this research were to determine the effect of substrates variation (rice, corn and dried cassava) on antioxidant activity and anti-cholesterol content in red yeast rice, and to determine the substrate(s) that produce the highest antioxidant activity and anticholesterol content. The design of this research was a Completely Randomized Design with one factor, i.e. the kind of substrates: rice, corn and dried cassava, with three replications. Then, the data were analyzed with ANOVA at a level of significance α=0.05, and continued with DMRT at the same level. This results showed that the effect of substrates kind to antioxidant activity and anti-cholesterol content on red yeast rice. The rice substrate had higher antioxidant activity and anti-cholesterol content than corn and dried cassava substrates. The antioxidant activity and the anti-cholesterol content on red yeast rice from rice substrate were 45.6100% and 0.026600%, respectively. The antioxidant activity and the anti-cholesterol content on red yeast rice from corn substrate were 44.0500% and 0.022833%, respectively, while the antioxidant activity and the anti-cholesterol content on red yeast rice from dried cassava substrate were 42.8333% and 0.013200%, respectively.

<p>The effects of brewing style on physicochemical indices, iso-a-acids and antioxidant contents of commercial beers were investigated. A great variability was highlighted for all the considered parameters (sugar and alcohol contents, density, pH, titratable acidity, iso-a-acids, phenolic content, antioxidant activity). The beers having the highest iso-a-acids contents were Guinness Special Export Stout (which also showed the highest phenolic content), Chimay Pères Trappistes Triple, and Greene King IPA whereas the lowest values were detected in Cuveè De Ranke, Heineken Premium Quality Lager, and Riedenburger Brauhaus gluten free. The latter also had the lowest phenolic concentration. The antioxidant activity values strictly correlated with the total phenolic content but not with the iso-?-acid amount. The Principal Component Analysis failed in distinguishing beers based on their declared type/styles. This was a predictable result since the beer styles don’t represent a compositional classification but they are rather used to indicate commercial types.</p>
