Health-promoting Properties Infusions of Hibiscus Flowers and Selected Berry Fruit Processing By-products

Aim: This study aimed to compare the health-promoting properties of hibiscus flowers infusions with pomace infusions from black chokeberry, blackcurrant, raspberry and strawberry. Methodology: Five types of fruit pomace infusions were selected as the research material: hibiscus flowers infusion and infusions from black chokeberry, blackcurrant, raspberry and strawberry pomace. The total polyphenol content, antioxidant activity and colour parameters were determined. Results: The highest content of phenolic compounds was found in hibiscus flowers infusion (453.25 mg GAE/L of infusion). Hibiscus flowers infusion also showed the highest antioxidant activity measured by DPPH, ABTS and FRAP tests. Among the tested infusions from selected berry fruit by-products, the infusion from chokeberry pomace was characterised by a high content of total phenolic compounds and antioxidant activity. The lowest total phenol content and antioxidant activity were found in the strawberry pomace infusion. Implications and recommendations: Despite their popularity and variety of flavours, commercial fruit teas that use fruit by-products need to be standardised in terms of their health-promoting content. This means that there is no uniform, controlled standard that specifies the amount of specific beneficial health-promoting ingredients in each package of fruit tea. The authors’ future research related to hibiscus flowers and berry pomace will focus on the influence of organoleptic characteristics on biological activity and the standardisation of the developed tea prototypes in terms of the content of health-promoting substances. Originality/value: According to the research, hibiscus flowers infusion has the highest antioxidant and colouring properties. Chokeberry pomace infusion showed antioxidant properties comparable to hibiscus flowers infusion. Consequently, the health-promoting properties and low cost of fruit processing by-products may contribute to their broader use in the tea industry.

Character Comparison Visualization Of Natural Indicators In Alkalimetric Titration

The use of natural materials began to be developed on a large scale in chemistry. Natural substances are safe to use, easy to find, and cheaper. Biological indicators in volumetric titration are the focus of experts. This study presented a visualization of the alkalimetric titration of a weak acid with a strong base with the addition of natural indicators. Hibiscus rosa-sinensis L. and Clitoria ternatea L. flowers were used as titration indicators for diprotic acid, namely oxalic acid, with a strong base, sodium hydroxide. The phenolphthalein indicator was chosen as an indicator to compare. Maceration of flower crowns aimed to obtain biological indicator extracts. The titration was held three times for the Hibiscus flower, Clitoria flower, and phenolphthalein. The addition of flower crown extract to oxalic acid gave a pink color to the solution. There was a color change to clear when titrated. The color change indicated the endpoint of the titration. The addition of the flower crown extract indicator showed a relatively similar curve to the phenolphthalein indicator during titration. This result showed that the two flower crown extracts had the same function as phenolphthalein as an indicator for alkalimetric titration of a weak acid with a strong base.

A Smartphone Coupled Freshness Indicator Prepared by Rub‐coating of Hibiscus Flowers on Paper substrates for Visual Monitoring of the Spoilage of Milk

AbstractThis study developed an inexpensive and easy‐to‐use milk freshness indicator (H‐Paper) by rub‐coating hibiscus flowers onto paper. As per the best of our knowledge, this is the first example of a food quality indicator prepared by direct hand‐rubbing of a natural halochromic material onto paper substrates. Unlike the previously reported colorimetric indicators from natural sources, our indicator does not require the extraction of anthocyanins from the natural product. The H‐Paper undergoes a quantifiable color change from green to purple to pink corresponding to fresh, spoiling, and spoiled milk samples. Digital photographs of H‐Paper treated with milk samples were acquired using a smartphone, and RGB indices were analyzed using a free application. The red chromatic shift was used as a parameter to quantify color change of H‐Paper to follow the spoilage of milk. Anthocyanins present in the hibiscus flowers are responsible for this colorimetric response. This work demonstrates a proof‐of‐concept for directly rub‐coating halochromic materials onto a substrate to fabricate food freshness indicators. The H‐Paper indicator has advantages of naked‐eye analysis, consumer‐friendliness, and instrument‐free operation. This requires neither any laboratory accessories nor the expertise of a trained analyst for its preparation and operation, which is appropriate for use in resource‐limited settings.

Essential Oil from Hibiscus Flowers through Advanced Microwave-Assisted Hydrodistillation and Conventional Hydrodistillation

Due to the increased demand and importance of essential oils in medicinal applications, advanced essential oil extraction techniques have been employed. Both conventional hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) were employed to extract the essential oils from the hibiscus flower. Extraction time and solvent polarity were the most critical factors. Scanning electron microscopy (SEM) was used to investigate the surface morphologies of raw powdered hibiscus flowers (not exposed to any pretreatment) and pretreated powdered hibiscus flowers (exposed to methanol absorption for 60 minutes prior to extraction). Extractive chemistry analysis utilizing Fourier transform infrared (FTIR) spectroscopy was performed on the volatile oil obtained by MAHD. Different peaks in the gas chromatography/mass spectrometry (GC/MS) analysis indicated the presence of thirty-seven different compositions. MAHD was more energy efficient, had higher yield production, and was environmentally friendly, reducing HD’s overall carbon footprint by 40%. Oxygenated monoterpene, sesquiterpene, and sesquiterpene hydrocarbons were found in the hibiscus flower’s crude extract. Moreover, the methanolic extract of Hibiscus rosa-sinensis has potent antioxidant properties. A hibiscus flower extract had scavenging activities of 51.2% at 0.2 mg/mL, 0.3% at 0.6 mg/mL, 0.8% at 1.0 mg/mL, and 68.5% at 1.2 mg/mL against DPPH free radicals. Therefore, the MAHD method is well-suited to extracting essential oils from hibiscus flowers, and the resulting oil has the potential to provide significant therapeutic advantages.

Feed Consumption and Growth Dynamics of Sheep Fed Agro-industrial Waste with Hibiscus rosasinencis Flower and Urea Supplementation

Optimizing the use of agro-industrial waste as an alternative feed ingredient for sheep requires the right strategy. The use of feed additives and supplements is needed to improve the performance of sheep in utilizing agro-industrial waste-based feed. The use of hibiscus flour as a source of saponins is important to optimize rumen microbial growth by suppressing the growth of protozoa. The addition of urea is used to supply nitrogen sources to optimize the performance of rumen microbes. This study used 15 thin tail sheep aged 8 months with an average weight of 13.98 ± 1.1 kg, the experimental design used was CRD (Completely Randomized Design) with 3 types of treatment and 5 times repetition, namely R1 (control / without supplementation), R2 (supplementation of 0.1 % hibiscus flower and Urea 0.5%), R3 (supplementation of 0.2% hibiscus flower and 1% Urea). The objective of this research was to measure feed consumption and growth dynamics. The results showed that the addition of hibiscus flour and urea to the feed formula had no significant effect on the feed consumption of sheep. The growth dynamics of sheep showed a decrease in the first week of the trial, and gradually showed an increase in the second week. The highest growth increase was achieved in R3 treatment at 6 weeks of the feeding trial. Based on the results of the study, it can be concluded that sheep fed with 0.2% hibiscus flour supplementation and 1% Urea (R3) showed the best ability in utilizing agro-industrial waste-based feed.
