“…Microbial fermentation produces ethanol in fruits and vegetables, which when consumed in excess can disturb the flavor of items (particularly fermented fruit and vegetable products) and exert a negative influence on their nutritional value (Doran‐Peterson et al., 2008). Consequently, a colorimetric indicator cube for intelligent packaging was conceived and manufactured to detect ethanol in dried mango fruit (Kaewnu et al., 2022). The indicator is composed of a porous melamine foam containing an indicator solution of potassium dichromate and sulfuric acid which presents a noticeable color change from yellow to brown, green, and blue over a range of ethanol concentrations from 0.25% to 5.0%.…”

“…Concerns about the quality and safety of F&V are frequently attributed to pesticide residues, microbiological deterioration, and infestation. Apart from conventional chromatographic and mass spectrometric detection (Umapathi et al., 2022), several intelligent detection methods have been employed to tackle these dilemmas, including colorimetric indicator labels (Kaewnu et al., 2022), TTI (Adiani et al., 2021), and biosensors (Deng et al., 2016; Hills et al., 2018; Mutreja et al., 2016). Pesticides may linger and infiltrate the food chain as a reaction to the excessive use of pesticides for pest control during the growing season of F&V, posing an ever‐growing threat to human health, which has become a serious public health issue (Umapathi et al., 2022).…”

“…Fruit and vegetable products that have suffered from fermentation are also extremely prone to microbial contamination. A colorimetric indicator cube containing potassium dichromate and sulfuric acid as an indicator solution has been manufactured to detect ethanol produced by microbial fermentation in dried mangoes, whose color change indirectly reveals the microbial content of the product (Kaewnu et al., 2022).…”

Post‐harvest fruits and vegetables are extremely susceptible to dramatic and accelerated quality deterioration deriving from their metabolism and adverse environmental influences. Given their vigorous physiological metabolism, monitoring means are lacking due to the extent that unnecessary waste and damage are caused. Numerous intelligent packaging studies have been hitherto carried out to investigate their potential for fruit and vegetable quality monitoring. This state‐of‐the‐art overview begins with recent advances in target metabolites for intelligent packaging of fruits and vegetables. Subsequently, the mechanisms of action between metabolites and packaging materials are presented. In particular, the exact categorization and function of intelligent packaging of fruits and vegetables, are all extensively and comprehensively described. In addition, for the sake of further research in this field, the obstacles that impede the scaling up and commercialization of intelligent packaging for fruits and vegetables are also explored, to present valuable references.

“…In this manner, high sample throughput was achieved to determine ethanol in various drink samples. Recently, a permeable membrane was fabricated on a Cr 2 O 7 2− -preloaded melamine foam as a novel ethanol indicator for preservation of baby mangoes [37]. e membraneless GD (abbreviated as MGD) was firstly proposed by Choengchan et al to overcome the drawbacks of clogging and frequent replacement of membrane when using GD or PV [36].…”

This work utilized the simplicity of a so-called membraneless vaporization (MBL-VP) unit as a gas separator for the colorimetric determination of ethanol in alcoholic beverages. A beverage sample with a volume of 1 mL was directly injected into a small container which was hung from a lid inside a closed 40 mL reused glass bottle without pretreatment such as distillation. An acidified potassium dichromate (Cr2O72−) acceptor solution, preadded to the glass bottle, was reduced to Chromium (III) ion by the diffusion of vaporized ethanol from the sample. After 5 min, the absorbing solution was collected for colorimetric detection at 590 nm. The unit manually quantifies ethanol in the range 1.0–90% (v/v) with satisfactory interday precision but without matrix effect (recovery 89−109%). The method was validated with the conventional distillation/pycnometer method which showed no significant difference of ethanol contents between those two methods and the declared values of 12 alcoholic beverages, indicating sufficient accuracy. Analyses of alcoholic beverages using this method were successful with benefits of simplicity, cheapness, and less energy consumption.

“…In recent years, rapid quantification by colorimetric analysis of digital images has received growing interest. This method has been used for the quantitative analysis of explosives [ 19 , 20 , 21 ] and other applications [ 22 , 23 , 24 ]. The method is based on the measurement of the intensity of red, green, and blue (RGB) basic color data in a digital image of a reaction product.…”

Polymer gel sensors on 96-well plates were successfully used to detect four different multi-explosives, including 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), nitrite, and perchlorate. The products of reactions between the explosives and the polymer gel sensors were digitally captured, and the images were analyzed by a developed Red–Green–Blue (RGB) analyzer program on a notebook computer. RGB color analysis provided the basic color data of the reaction products for the quantification of the explosives. The results provided good linear range, sensitivity, limit of detection, limit of quantitation, specificity, interference tolerance, and recovery. The method demonstrated great potential to detect explosives by colorimetric analysis of digital images of samples on 96-well plates. It is possible to apply the proposed method for quantitative on-site field screening of multi-explosives.
