Abstract

Current efforts to explore the potency of marine resources have been made to promote economic development in Indonesia, especially in the industrial sector. Marine cyanobacteria such as Arthospira sp. and Scytonema sp. are two potential candidates of the blue-green algae that can be used in the application for food and health industries. This study focused on the identification of the composition of the dominant chlorophylls and carotenoids. The results showed the presence of Zeaxanthin, Chlorophyll a, and β-carotene. The economic potency of those dominant pigments will be reviewed in this article.

Abstract

Non-destructive measurement of plant chlorophyll concentration using the normalized difference vegetation index (NDVI) has long been standard practice to determine the plant health status. This is, because the NDVI value is correlated with the chlorophyll concentration which in turn is highly correlated with other vital plant parameters such as nitrogen and magnesium concentration. Initially the NDVI values were obtained from satellite imagery and thus could only be used to assess the health status of bigger ecosystems like forests and crop fields. With the introduction of handheld chlorophyll meters like the Chlorophyll Meter SPAD-502 Plus made by Konica Minolta, the same principle could be used to determine the chlorophyll concentration of single leaves. However, these devices still have one major shortcoming: They can only measure the chlorophyll concentration on one single spot on the leaf at a time. But depending on the species the chlorophyll concentration tends to vary significantly over the leaf. To overcome this shortcoming, we developed our PlantAnalyzer which offers better spatial resolution of the NDVI values and hence the chlorophyll concentration. Its technical realization and precision shall be elaborated in the following article.

Abstract

In the present work, a comprehensive statistical analysis was performed to evaluate the potential application of peel of local fruits from Malang, i.e. mangosteen, honey pineapple and red dragon fruits for natural yellow coloring agents. The yellow pigments from those fruit peels were extracted through a simple maceration method using distilled water, acetone and ethanol as the solvents. The CIE color space of the extracts was measured to obtain L*, a* and b* values. The obtained data were further analyzed using Principal Component Analysis (PCA), Multivariate Analysis of Variance (MANOVA) and Duncan Test to determine the most potent natural yellow coloring agent. All the extracts were appeared as mild to strong yellow liquid except for acetone extract for the peel of red dragon fruit extracts. From the CIE color space and PCA analysis, either ethanolic or acetone extracts of mangosteen appears as a strong yellow liquid and they are statistically not different. Interestingly, the MANOVA and Duncan test results are able to distinguish that the ethanolic extract of mangosteens’ peel as the best candidate for natural yellow coloring agents because of its lowest L* and also highest b* variable values.

Abstract

Sweet potatoes, especially the orange and yellow-fleshed, are functional local food because they contain carotenoids which serve as a pro-vitamin A. The processing of sweet potatoes into noodles, fermented cassava or “tape” and artificial rice is usually prepared through steaming. However, carotenoid is susceptible to degrade when it is subjected to high temperature, such as steaming. The objective of this research is to determine the effects of steaming on the color and carotenoid absorption spectra of local and excellent sweet potatoes which are correlated to the carotenoid content and to evaluate the difference of carotenoid spectral properties among sweet potatoes by principal component analysis (PCA). The steaming treatment decreased color values, such as lightness, redness, and yellowness. In addition, this process also influenced the spectral properties of carotenoid extracts of sweet potatoes. Steaming decreased absorbance and resulted in hypsochromic and bathochromic shifts. Madu Mojokerto, Manohara, local purple fleshed, Beta 1, and Papua Solossa sweet potatoes experienced some decreases in absorbance and a hypsochromic shift of ± 77 % and ± 2 nm, ± 40 % and ± 21 nm, ± 63 % and ± 28 nm, ± 44 % and ± 2 nm, and ± 20 % and ± 23 nm, respectively; while Antin 3 sweet potatoes experienced some decrease in absorbance of ± 36 % and a bathochromic shift of ± 28 nm. The PCA results showed that there were four groups of sweet potatoes based on spectrum shape and absorbance value.

Abstract

Banana peel is a promising source to be utilized in fortification of food products due to the high content of carotenoids (Cars) which are active as provitamin A. Dominant, total and relative concentrations of Cars were determined from fresh flesh and peel in three cultivars of banana obtained from Raja, Ambon Kuning, and Kepok Kuning. To evaluate the difference in Car compositions principal component analysis (PCA) was also performed. Based on chromatographic, spectroscopic, and mass spectrometric analyses, dominant Cars were separated and identified to be lutein, α-carotene and β-carotene. Lutein was the major Car of fresh peel, while other two Cars were found in fresh flesh in addition to lutein. Raja banana had the highest total concentration of Cars among three banana samples used. PCA results generated from the absorption spectra showed three clusters of the different banana samples. PCA results are correlated to their Car compositions and this method might be applicable for the determination of dominant Cars.

Abstract

Suji (Pleomele angustifolia) is one kind of Indonesian typical plants which can be used as natural green food coloring agent. The susceptibility of natural pigment to external environment forces the protection in order to prolong its shelf life. Encapsulation has been known in the art of food preparation to provide protection for several ingredients including food coloring agent. The objective of this study was to observe the method for isolation and encapsulation of thylakoid, and to investigate the stability and characteristics of thylakoid of suji leaves encapsulated in maltodextrin during dark storage at 30 °C, 45 °C, and 60 °C. The degradation of the encapsulated pigments was identified through chromametric analysis which resulted in the increase of L* (lightness), a* (redness), and b* (yellowness) values. In addition, it was also indicated by the decrease of total chlorophyll (TC) which was determined using spectrophotometer. Chromatography analysis confirmed the presence of four major peaks in the fresh encapsulated thylakoid powder and five major peaks in the encapsulated thylakoid powder stored at the highest temperature (60 °C), with Chl a as the dominant pigments in both powder. The vivid green powder was able to preserve its color without any obvious change to an untrained eye up to 60 d of storage at 30 °C, becoming a promising ingredient to replace the synthetic colorants.
