Vegetables are essential in our diet to maintain health, partly due to their antioxidant properties. A well-known Javanese salad called “Pecel” is prepared by boiling the vegetables and dressed with seasoned peanut sauce. Cooking can reduce or improve the antioxidant properties of foods; therefore, the purpose of this study was to evaluate the effects of brief water boiling (1 min), steaming (1 min), and water blanching (20 s) of the Javanese Pecel vegetables, with or without the peanut sauce. We assessed the in vitro antioxidant capacity and lipid peroxidation inhibition of the salad samples prepared using each cooking method. Six vegetables, i.e., Sesbania grandiflora (turi) flower, Amaranthus hybridus L. (spinach), Carica papaya (papaya) leaves, Cosmos caudatus L. (kenikir) leaves, Vigna unguiculata ssp. Sesquipedalis (yard-long beans), and Vigna radiata (mung-bean) sprouts were cooked by boiling or steaming for 1 min or blanching for 20 s. Peanut (Arachis hypogaea), the raw material for peanut sauce, was fried in either fresh palm oil or repeatedly used palm oil. Our results revealed that the highest antioxidant capacity (percent inhibition of DPPH radicals) was observed following boiling for 1 min in case of spinach ( 41.94 ± 9.8 %), papaya ( 59.04 ± 5.35 %), kenikir ( 54.93 % ± 6.32 % ), and yard-long beans ( 70.21 ± 8.91 %); steaming for 1 min in case of turi flower ( 60.25 ± 3.63 %); and blanching for 20 s in case of mung-bean sprouts ( 49.27 ± 3.69 %). Peanut sauce prepared by frying peanuts in fresh or repeatedly used palm oil reduces the natural antioxidant and lipid peroxidation inhibition properties. However, seasoning the peanut sauce with fresh garlic and lime leaves can restore the lost antioxidant properties. Our study provides the first and clear evidence of the optimal cooking method for Pecel vegetables and sheds light on the wisdom behind the existing traditional cooking method.

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.

Background: High-fat diet increases the levels of fat, especially cholesterol and triglycerides that cause hyperlipidemia. Polyunsaturated fatty acids are very easily oxidized by free radicals reactive oxygens species (ROS) called lipid peroxidation, to produce compounds that malondialdehyde (MDA), is toxic and can damage plasma membrane and liver tissue. Mung bean sprouts are known to contain antioxidants which act to inhibit lipid peroxidation process.Objective: Determine the effect of mung bean sprouts to the level of plasma MDA and liver tissue of rats with high-fat diets.Method: This research is an experimental study with an only post-test design with the control group. Thirty-five male Sprague-Dawley rats were divided into 5 groups. Group K1 received fed standard; K2 received high-fat diet without mung bean sprouts. Group P1 received high-fat diet and mung bean sprouts dose of  0.5 mL/gBW. Group P2 received high-fat diet and mung bean sprouts dose of 1 mL/gBW. Group P3 received high-fat diet and vitamin E doses of 23 IU. All group were treated for 28 days. Analysis of MDA plasma and liver tissue performed after treatment.Results: Group K1 has plasma MDA levels of 1.17 ± 0.14 nmol/mL Mean MDA plasma level in the group K1 Group of K1 Mean MDA plasma level in the group K2 (39.7±0.19 nmol/mL) was higher than the group of K1 (1,17±0,14 nmol/mL), group P1 (2.94±0.09 nmol/mL), group P2 (1.73±0.08 nmol/mL) and group P3 (1.53±0.07 nmol/mL). Group K1 has liver tissue MDA Levels of 1,64±0,11 nmol/g. Mean MDA liver tissue level in the group of K2 (4.90±0.29 nmol/g) was higher than the group of P1 (3.68±0.45 nmol/g), group P2 (2.27±0.10 nmol/g), and group P3 (2.01±0.11 nmol/g).Conclusion: Level of MDA plasma and liver tissue of rat in group P1 and P2 was lower than a level of MDA plasma and liver tissue of rat in group K1, but higher than the level of MDA plasma and liver tissue of rat in group P3. There was a very strong correlation between the level of MDA plasma and liver tissue of rat was given the mung bean sprouts and high-fat diet.

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.

Native biofilms present on the adaxial surface of cotyledons of mung bean sprouts (Vigna radiata) were studied by use of scanning electron microscopy. Biofilms were abundant on the cotyledon surfaces and were comprised of rod-shaped bacteria, cocci-shaped bacteria, or yeasts, often with one type of microbe predominant. In contrast to our earlier study of biofilms on green sprouts (alfalfa, clover, broccoli, and sunflower), yeast and cocci were abundant on mung bean. Filamentous fungi were not observed. Sheet-like or fibrillar material (presumably composed of secreted microbial polysaccharides, proteins, lipids, and nucleic acids) fully or partially covered the biofilms. Biofilms up to 5 mm in length were observed, and some biofilms were comprised of more than just a monolayer of microbial cells. Native biofilms on sprout surfaces undoubtedly play an important role in the ecology of plant epiphytic microbes and may also afford protected sites for plant and human bacterial pathogens.Key words: mung bean sprouts, biofilms, native microflora, scanning electron microscopy, food safety.
