Purpose – This study aims to investigate the awareness of Muslim students regarding Istihalah in their daily life. The study was carried out to investigate attitude and awareness towards Istihalah among Muslim students in Universiti Pertanian Bogor (UPB), Indonesia. Design/methodology/approach – In total, 456 students were randomly selected from the university. A self-administered questionnaire was handed out to consenting students focusing on attitude and awareness towards Istihalah and eagerness to learn more about Istihalah. Findings – Results showed that Muslim students lacked information about Istihalah. From the total number of students 86.18 per cent agreed that information and knowledge of Istihalah is scarce. 40.1 per cent believed that Ulamas (Muslim scholars) are a very important source of knowledge regarding Istihalah, and 87.50 per cent are willing to learn more about Istihalah. Research limitations/implications – The respondents in this study were Muslim students in UPB, Indonesia. The results of this study are only applicable to the specific community. Thus, extrapolation of the results to represent society at large is not possible. The study merely attempts to investigate the prevalence of the concept among students of the university. Originality/value – This study is formed as a novel study to explore the attitude and awareness towards Istihalah among Muslim students in UPB, Indonesia. Students being representatives of the educated society are important links in creating awareness of the concept of Istihalah at large. This pilot study is the second of its kind, and prior study of Istihalah with regards to community awareness is limited to just one other performed by the same team. [ABSTRACT FROM AUTHOR]

The peel of Hylocereus polyrhizus is often regarded as a waste hence this study was aimed at exploring the feasibility of using the peel as a natural colorant using simple water extraction method. Samples were subjected to a series of temperatures: Room temperature (RT), 50, 80 and 100 degrees C; varied length of heating time from 1, 2, 3, 4, 5 and 10 min and a varied range of pH using 1 M of citric acid solution. The best condition to obtain highest betacyanin content was heating samples at 100 degrees C for 5 min in a pH 5 citric acid solution. The next part of this study involved the stability test of the pigments obtained through the best method determined earlier. The pigments were dried and resuspended in distilled water. The samples were then exposed to light to monitor pigment changes. Initial resuspension of the dried pigments yielded a comparable high content of betacyanins to its juice counterpart. The results showed that resuspended pigments had high pigment retention and were stable up to 7 days. These initial findings must be further studied in more controlled conditions to understand the stability of betacyanin. Nevertheless, the results show that betacyanin obtained from the peel of dragon fruit has a high potential to be used as a natural dye.
