Spectrophotometric Folin-Ciocalteu and Aluminium Chloride Method Validation for the Determination of Phenolic Acid, Flavan-3-ol, Flavonol, and Anthocyanin Content
Authors: Matić Petra , Jakobek Lidija
Published: January 2022

Spectrophotometric methods for the determination of total polyphenols and
total flavonoids are often used because they are simple, sensitive, and precise.
Before using these methods, they must be validated to ensure the quality of the
obtained data and to prove that the method is suitable for its purpose. The aim
of this study was to validate the spectrophotometric methods for total
polyphenols and total flavonoids. The method for total polyphenols has been
validated according to polyphenol standards, which belong to the groups of
phenolic acids (p-hydroxybenzoic acid, sinapic acid, ferulic acid), flavan-3-ols
((-)-epicatechin), flavonols (myricetin, kaempferol), and anthocyanins
(cyanidin-3-glucoside). For the validation of the method for total flavonoids,
the same polyphenol standards belonging to flavan-3-ols, flavonols, and
anthocyanins have been used. The validation parameters were linearity,
sensitivity, limit of detection, limit of quantification, precision, and accuracy.
The results of the validation for both methods were in acceptable ranges, except
for kaempferol in the method for total flavonoids. In conclusion, these methods
can be used for the determination of total polyphenols and total flavonoids by
using calibration curves of studied polyphenol standards, except for the
kaempferol standard in the method for total flavonoids, due to lower sensitivity

Published: January 2022

In this study, commercially available traditional blackberry products, namely
blackberry wines and blackberry elixirs from Coastal Croatia and Bosnia and
Herzegovina, were investigated as sources of bioactive compounds, essential
nutrients and metals. Samples were analysed for pH, total polyphenols and
monomeric anthocyanins content, individual phenolic acids (gallic acid,
chlorogenic acid, caffeic acid and p-coumaric acid), antioxidant activity
(DPPH and ABTS), reducing power (RPA), total nitrogen and phosphorus as
well as metals (K, Na, Ca, Mg, Fe, Mn, Cu, Zn, Co, Cr, Cd). The results of this
study showed that the studied traditional blackberry products are rich sources
of polyphenols and their consumption could increase the daily intake of dietary
antioxidants in humans. In addition, both groups of traditional blackberry
products could be considered safe for health and good additional sources of
essential minerals such as manganese and potassium. The concentrations of the

Authors: Gotal Ana-Marija , Kovač Tihomir , Lončarić Ante
Published: January 2022

Apples are one of the most popular foods around the world. However, recently
there has been a growing interest in the preservation of traditional apple
varieties. This interest has grown due to the studies that suggest that traditional
apples contain higher amounts of polyphenolics and antioxidant activity
compared to commercial ones. Polyphenolics in apples have gained much
attention because of their beneficial effects on human health, and thus they
became a quality trait of apples. Traditional apple varieties have the same
groups of polyphenols as commercial ones and those are flavan-3-ols, phenolic
acids, flavonols, dihydrochalcones, and anthocyanins. However, traditional
apple varieties proved to be rich in some individual polyphenolics, such as
procyanidins B1, B2, A2, epicatechin, quercetin-3-rutinoside, chlorogenic
acid, etc. This chapter is underlying the great potential of traditional apple
varieties as a source of some individual polyphenolics and natural antioxidants.

Published: January 2022

Internationalisation of higher education definition has evolved and so are the approaches in its implementation. The internationalisation of higher education is executed either one of the two approaches, the activity or the process approach, including in the higher education institutions in Malaysia. By giving the attention on one approach alone could contribute to issues in the less focused approach and hinder institutions from receiving maximum benefit from internationalisation. Thus, this study explores the nature of internationalisation approaches in the experiences of meso-level professionals and individuals in the micro level of the institution, specifically at the Universiti Tun Hussein Onn Malaysia (UTHM). The qualitative case study is adopted to gain adequate information from the internationalisation actors of the institution. The information is collected through face-to-face interviews, participatory observations, and documents analysis. Literature found that most of the higher education institutions practiced the activity approach in the implementation of internationalisation at the majority of higher education institutions. This should also happen to the internationalisation practices at UTHM where the execution is driven by the meso-level professionals of the institution. However, internationalisation experts have long promoted internationalisation practices to be in a dynamic activity – process fashion. Result of this study offers the policymakers, internationalisation key actors and stakeholders, valuable information on the internationalisation approaches to serve as a guideline in measuring the internationalisation practices, strategies development and quality improvement in the higher education system in Malaysia.

Burning rock coal which is a source of electricity generation, is a contributor to the effects of the ecological crisis in the world. This caused the world needs new energy sources, such as piezoelectric, etc. The manufacture of piezoelectric mats as house bells aims to show that there is alternative energy for power generation in order to reduce the use of coal in Indonesia. By reducing the use of coal, it will reduce the occurrence of an ecological crisis. The research method we used was an experiment with planning, design and implementation stages. The renewal of this project is to assemble and apply the piezoelectric directly to objects that require electrical energy by replacing the power source from the piezoelectric system, and implementing it for house bells. Piezoelectric mat is a mat that can generate electrical energy if the surface is pressed. This energy can be generated from the piezoelectric that is installed on the inside of the mat. Piezo mats will be installed to be stepped on by guests visiting a house. This foot step will put pressure on the mat. The more tread is obtained, the more electricity is generated. This piezo carpet will be installed in front of the house. The use of piezo mats is an effort to utilize mechanical energy in the form of pressure generated by footrests into electrical energy.

The increasing number of deaths due to COVID-19 followed by an excessive number of burials had risen the emergence of a safety plan, supporting the burial process to minimize the dangerous impact on the human. The conventional way of burying the corpse with infectious disease in Indonesia utilizes ropes to lower the coffin and involves four to eight people. However, this is not practical because it is energy-wasting and crowding. This paper aims to propose a design of a safe, practical, and robust coffin lowering machine. The proposed design is available for all ages with a weight of up to 200 kg. The design has a 2000 x 600 x 750 mm dimension, in which the width can be extended from 600 to 1000 mm. The straps for lowering the coffin are mounted on the left and right-side shafts. Each of the components is connected with a pin joint. Then, the components are analyzed by calculating the static and fatigue strength to obtain the safety factor and to determine the service life. As a result, the proposed design demonstrates the safety factors for static and fatigue condition that are higher than one, indicating it can be considered for fabrication. In addition, the presented work can be referred as a problem-based learning case study in Machine Element Course.

Published: January 2022

Gas chromatography mass spectrometry (GC/MS) analysis is used as analytical tool for volatile and complex mixture samples. Its effectivity and sensitivity to detect the analyte components make it applicable in a wide range of purposes. This technique can be used to conduct quantitative as well as qualitative analysis. Unfortunately, very few, if there are, of publications dedicate the research to give an explanatory report using a step-by-step approach on how to read and interpret the analysis result. Thus, this study is aimed to fulfill the gap on bridging the spectra data output of GC/MS measurement into the light of easy way reading and interpreting its spectra. The research method used both library spectra matching and a priory spectra interpretation on chosen compound samples. The general guideline and application are discussed.
