“…Among starchy plants, arrowroot (Maranta arundinacea) has high potential as raw material for starch extraction. Starch found in arrowroot rhyzomes, unlike corn and manioc starch, has digestibility characteristics and high content of amylose, a polymer that has great ability to form films (Guilherme et al, 2019;Nogueira et al, 2018). However, it should be highlighted that there are few studies of arrowroot starch, despite its excellent physico-chemical characteristics.…”

Capsicum spp. pepper has great economic and social importance in agribusiness worldwide, mainly associated with its high performance in cookery as a spice. This study aimed at determining the chemical profile of the ethanolic extract from Capsicum chinense Jacq. (EECC) ripe fruits by liquid chromatography-mass spectrometry (LC-MS) and at evaluating its antioxidant activity by DPPH, ABTS and FRAP. Besides, biodegradable films were prepared by incorporating EECC into arrowroot biofilms. LC-MS identified 10 phenolic compounds, a fact that corroborates its high concentration of total phenolic compounds, i. e., 277.62 ± 12.06 mg gallic acid/100g crude extract. High antioxidant activity of EECC was expressed as IC 50 values for reagents DPPH (IC 50 = 18.04 µg/mL), ABTS (IC 50 = 25.33 µg/mL) and FRAP (IC 50 = 128.58 µg/mL). Biodegradable films incorporating different doses of EECC (250-1000 µL) were obtained by a casting technique. The higher the EECC concentration, the higher their thickness, color, variable moisture content and the lower their solubility. This study proposes a new use to the plant extract from C. chinense, a natural product that may be applied to the development of biofilms to coat food and retard its deterioration. In addition, antioxidant activity of this type of pepper is also shown.

“…However, the scarcity of arrowroot starch on the market implies a price increase and favors the occurrence of fraud through substitution with cheaper sources, such as commercial cassava or potato starches. The major challenges in identifying this fraud are the impossibility of visual discernment and the usual inconclusive analytical approaches [3].…”

Food frauds present a major problem in the foodstuff industry. Arrowroot and cassava may be targeted in adulteration and falsification processes. Raman analysis combined with chemometric techniques was proposed to identify the mixing and adulteration of these foodstuffs in commercial products. 67 cassava and 5 arrowroot samples were prepared in laboratory. 21 cassava and 5 arrowroot commercial samples were purchased in local stores. Raman assays were performed in the range of 400 to 2300 cm−1. Principal component analysis with K-means clustering was used to identify the adulteration of these products. It was possible to observe the separation of three different groups in the data, these groups labelled group 1, 2 and 3 were correspondent to cassava-like samples, mixed samples, and arrowroot-like samples, respectively. Despite the visual analysis related to sensory characteristics and the visual analysis of each Raman spectrum of cassava and arrowroot not being able to differentiate these foodstuffs, the chemometric approaches with the Raman specters data were able to identify which samples were pure arrowroot, pure cassava and which were mixed products. The proposed approach showed to be an effective tool in the investigation of fraud for arrowroot and cassava.

“…), depending on the variety and crop conditions (Leonel & Cereda, 2002;Malinis & Pacardo, 2012). Its starch is appealing to the European market owing to its reported special properties for fine confectionery (Sá et al, 2015); specifically, in England, the mixture of wheat flour with arrowroot starch is considered the best to make puddings and bakery creams (Guilherme et al, 2019).…”

GRANULOMETRY AND ENERGY CONSUMPTION AS INDICATORS OF DISINTEGRATION EFFICIENCY IN A HAMMER MILL ADAPTED TO EXTRACTING ARROWROOT STARCH (Maranta arundinacea) IN COMPARISON TO STARCH EXTRACTION FROM CASSAVA

2019

The commercial sector of starch extraction has fully automated plants with a minimum scale of 200 ton.day-1 , which extracts starch from maize and cassava in Brazil. Although these starches are commodities, the market demands starches with special properties obtained without chemical modifications. A higher-priced starch can compensate for small-scale extraction, as in the case of arrowroot starch, which would correspond to an alternative income for the producer. As a small-scale equipment was not available in Brazil, it was necessary to adapt a hammer mill for arrowroot starch extraction, which should have a performance similar to that obtained from cassava roots using industrial grinders. The degree of disintegration and energy consumption were adopted as the efficiency indexes. The hammer mill was equipped with two perforated plates. The results showed that use of an adapted hammer mill provides an average diameter of 74.64 ± 0.09 μm for perforated plate 1 (TP1) and 76.62 ± 0.06 μm for TP2; these results were equivalent to those obtained with cassava in the respective perforations which, in turn, was comparable to the degree of grinding obtained with large industrial equipment. The specific energy consumption needs for arrowroot disintegration varied from 31.47 to 48.91 kJ.kg-1 , which was considered close to that calculated for large-scale industrial cassava roots grinders, reported at 37.03 kJ.kg-1 .
