Study on nutritional characteristics and antioxidant capacity of mung bean during germination

In this study, 22 mung bean varieties from different producing areas in China were used as materials to provide a theoretical basis for the breeding and utilisation of special mung bean sprout varieties. Principal component analysis and cluster analysis were used to comprehensively evaluate the overall quality. Finally, 22 germinated mung bean varieties were divided into 3 edible quality grades according to their quality scores. The results showed that Lvfeng 2 and Ankang mung bean sprouts with better comprehensive characters were varieties with higher scores, which could be developed and utilised as characteristic mung bean sprouts. The content of protein, total phenol and antioxidant capacity of edible parts of Lvfeng 2 and Ankang mung bean after germination are higher than those of other varieties, so they are suitable for research and development as functional mung bean sprouts.

Pengaruh Pemberian Ekstrak Bawang Merah dan Kecambah dengan Pemberian Pupuk Cair Hayati terhadap Pertumbuhan Seedling Manggis (Garcinia mangostana L.)

Mangosteen (Garcinia mangostana L) seeds from seed, or commonly called seedling, have relatively few lateral roots and are poor in root hairs so that their growth is slow (having a long juvenile period of up to 10-15 years). For this reason, it is necessary to make efforts so that mangosteen seedlings can have a good root system through the addition of natural growth regulators. The purpose of this study was to determine the effect of red onion extract, a mixture of onion extract and mung bean sprouts combined with biological liquid fertilizer on the growth of mangosteen seedling. This research was carried out in the Horticulture FP greenhouse in March 2020–July 2020. This study was arranged in a factorial (3 x 2) in a Randomized Block Design (RAK) with three replications. The first factor was natural ZPT treatment: without extract, red onion extract 400 g/L, and mixed extract of onion 200 g/L and green bean sprouts 200 g/L. The second factor is the provision of biological fertilizers, namely without biological fertilizers and 15 ml/L). The results showed that the administration of mixed extracts of shallots and mung bean sprouts tended to have better growth which could be seen from the highest average value for the variable plant height 6.04 cm, stem diameter 2.93 mm, and the number of secondary roots. The mixed extract treatment of shallots and mung bean sprouts also increased the widest leaf area by a difference of 3.5 cm² compared to the control.

Monitoring the incidence and causes of disease potentially transmitted by food in Australia: Annual report of the OzFoodNet network, 2016

In 2016, a total of 44,455 notifications of enteric diseases potentially related to food were received by state and territory health departments in Australia. Consistent with previous years, campylobacteriosis (n = 24,171) and salmonellosis (n = 18,060) were the most frequently-notified infections. Notable increases in incidence were observed for shiga toxin-producing Escherichia coli (n = 343; 166% increase), shigellosis (n = 1,408; 93% increase), campylobacteriosis (33% increase) and salmonellosis (30% increase) when compared with the historical five-year mean. The extent to which the introduction of culture-independent testing as a method of diagnosis has contributed to these increases remains unclear. In total, 188 gastrointestinal outbreaks, including 177 foodborne outbreaks, were reported in 2016. The 11 non-foodborne outbreaks were due to environmental or probable environmental transmission (nine outbreaks) and animal-to-person or probable animal-to-person transmission (two outbreaks). No outbreaks of waterborne or probable waterborne transmission were reported in 2016. Foodborne outbreaks affected 3,639 people, resulting in at least 348 hospital admissions and four deaths. Eggs continue to be a source of Salmonella Typhimurium infection across the country: 35 egg-related outbreaks, affecting approximately 510 people, were reported across six jurisdictions in 2016. Three large multi-jurisdictional Salmonella outbreaks associated with mung bean sprouts (n = 419 cases); bagged salad products (n = 311 cases); and rockmelons (n = 144 cases) were investigated in 2016. These outbreaks highlight the risks associated with fresh raw produce and the ongoing need for producers, retailers and consumers to implement strategies to reduce potential Salmonella contamination.

METODE PENGEMASAN TAUGE KACANG HIJAU MENGGUNAKAN PLASTIK POLIETILIN DAN POLIPROPILIN PADA PENYIMPANAN SUHU RENDAH

Green bean sprouts are a type of vegetable that has a short shelf life. To extend the shelf life of these vegetables, they need to be stored by appropriate packaging methods. The aim of this study was to apply polyethylene (PE) and polypropylene (PP) plastic packaging to increase the shelf life of mung bean sprouts. The research was conducted by packing mung bean sprouts in PE and PP plastic at storage temperatures of 10 and 29 °C for 9 days. The parameters observed were weight loss, respiration rate, color, moisture content, and aroma. The results showed that mung bean sprouts stored in PE packaging had a longer shelf life than PP packaging. The shelf life of mung bean sprouts using PE packaging is 5 days, while PP packaging can only last 3 days at 10 °C. The shelf life of mung bean sprouts using PE packaging is 4 days, while the PP packaging can only last 2 days at 29 °C. Keywords: green bean sprouts, packaging, PE plastic, storage, temperature

Spicy Herb Extracts as a Potential Improver of the Antioxidant Properties and Inhibitor of Enzymatic Browning and Endogenous Microbiota Growth in Stored Mung Bean Sprouts

The quality and shelf life of sprouts can be improved by postharvest application of water herb extracts. The effect of water infusions of marjoram, oregano, basil, and thyme on the phenolic content, antioxidant potential, and the microbiological and consumer quality of stored mung bean sprouts was studied. Compared to the control, the treatments increased total phenolic content. The highest amounts were determined in sprouts soaked in the thyme extract (6.8 mg/g d.m.). The infusions also inhibited the activity of enzymes utilizing phenolics, and marjoram and oregano were found to be the most effective. The increase in the level of phenolics was reflected in enhanced antioxidant properties (ability to quench cation radical ABTS•+, reducing and chelating power). Both total phenolics and flavonoids, as well as antioxidant capacities, were highly bioaccessible in vitro. All the natural extracts effectively reduced the growth of total mesophilic bacteria, coliforms, and molds (they were more effective than ascorbic and kojic acids). The treatments did not exert a negative influence on the sensory properties or nutritional value of the sprouts, and even improved starch and protein digestibility. These results are very promising and may suggest a wider used of natural extracts as preservatives of minimally processed food.
