Effects of addition of Sodium Benzoate of the Physicochemical Characteristic of Watermelon rind (Citrullus lanatus)

Watermelon rind is a food product that utilize wasted albedo waste. Generally, jam is gel or semi-dense so it has short shelf life. To make the jam more imperishable in storage, preservatives can be added in manufactured progress, one of the preservatives that can be used is sodium benzoate. This research aims to determine the effects of the addition of sodium benzoate on the physicochemical characteristics of watermelon rind jam. The results reveals that the formula of watermelon rind jam with the addition of sodium benzoate has physicochemical content that not much different apart from the one that isn’t added by sodium benzoate. The characteristics that were significantly different were only in viscosity, the jam with the addition of sodium benzoate (6400 cP) was greater than the jam without the addition of sodium benzoate (2900 cP). The selected formula will be tested by organoleptic (hedonic quality) with texture, taste, and aroma attributes with the results that the jam formula was well received by 30 panelists. The quality of watermelon rind jam is identified by color aspect with average score of 5.10 with good category that has brownish yellow color, by texture with average score of 5.10 with good category that has soft and fibrous textured, and by the taste with average score of 5,20 with good category that has sweet acidity taste.

Sodium Benzoate, a Metabolite of Cinnamon and a Food Additive, Improves Cognitive Functions in Mice after Controlled Cortical Impact Injury

Traumatic brain injury (TBI) is a major health concern, sometimes leading to long-term neurological disability, especially in children, young adults and war veterans. Although research investigators and clinicians have applied different treatment strategies or neurosurgical procedures to solve this health issue, we are still in need of an effective therapy to halt the pathogenesis of brain injury. Earlier, we reported that sodium benzoate (NaB), a metabolite of cinnamon and a Food and Drug Administration-approved drug against urea cycle disorders and glycine encephalopathy, protects neurons in animal models of Parkinson’s disease and Alzheimer’s disease. This study was undertaken to examine the therapeutic efficacy of NaB in a controlled cortical impact (CCI)-induced preclinical mouse model of TBI. Oral treatment with NaB, but not sodium formate (NaFO), was found to decrease the activation of microglia and astrocytes and to inhibit the expression of inducible nitric oxide synthase (iNOS) in the hippocampus and cortex of CCI-insulted mice. Further, administration of NaB also reduced the vascular damage and decreased the size of the lesion cavity in the brain of CCI-induced mice. Importantly, NaB-treated mice showed significant improvements in memory and locomotor functions as well as displaying a substantial reduction in depression-like behaviors. These results delineate a novel neuroprotective property of NaB, highlighting its possible therapeutic importance in TBI.

Cadence discovery: study protocol for a dose-finding and mechanism of action clinical trial of sodium benzoate in people with treatment-refractory schizophrenia

Background Schizophrenia is a persistent psychotic disorder often accompanied by severe disability and premature mortality. New pharmacological treatments are urgently needed. Sodium benzoate, a common food preservative holds potential to be an effective, accessible treatment for schizophrenia, though the optimal dosing and mechanism of action of the compound requires further investigation. Methods Individuals with persistent treatment-refractory schizophrenia (n=52) will be recruited. Patients will be randomised in a 1:1:1:1 ratio to receive treatment of one of three active doses (1000, 2000 or 4000 mg daily) of sodium benzoate or placebo for 6 weeks duration. The primary outcome measurement is change in the Positive and Negative Syndrome Scale (PANSS) total score. Secondary outcome measurements are PANSS subscales, Global Assessment of Function (GAF), Clinical Global Impression (CGI) and Patient Global Impression (PGI-I). Change in concentrations of peripheral amino acids (D-alanine, L-alanine, D-serine, L-serine, glycine and glutamate), plasma sodium benzoate, plasma catalase, 3-nitrotyrosine, malondialdehyde and high-sensitivity C-reactive protein (hs-CRP) will be determined as tertiary measures. Discussion This trial seeks to build upon previous research indicating potential efficacy of sodium benzoate for reduction of symptoms in individuals with treatment-refractory schizophrenia. The trial aims to improve the understanding of the mechanism of action of the compound. Trial registration Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12621000327886.

Anti-fertility effect of three inorganic salts against land snail, Massylaea vermiculata, (O.F. Müller1774) and their field efficiency

Background The ovotestis gland (the hermaphrodite gland) is a reproductive system organ that affects fertility of land snails. Thus, the present study was conducted to evaluate the effect of three inorganic salts (sodium carbonate, sodium benzoate, and sodium nitrate) against the land snail, Massylaea vermiculata under laboratory and field conditions. Snails were treated with serial concentrations of the tested salts for seven days using thin-layer film technique. The LC50 of each salt was determined, and the effect of ½ LC50 of each was tested on egg-laying. In addition, LPO enzyme was determined, and the histological effect of the ovotestis gland was inspected. The field efficiency of sodium carbonate and sodium nitrate were evaluated as a spray for 21 days on pomegranate nursery trees at Giza Governorate. The effects of inorganic salts were compared with methomyl (the compound recommended by the Egyptian Ministry of Agriculture against land snails in the field). Results The laboratory results revealed that sodium carbonate and sodium nitrate were more toxic than sodium benzoate, whereas the LC50 were 2.4, 9.6, and 11.8% for the three inorganic salts, respectively. Sodium carbonate and sodium nitrate achieved complete inhibition for egg production, while sodium benzoate gave 37.7% compared to 96.8% for hatchability control. Sodium carbonate and sodium benzoate exhibited significant effect on LPO enzyme, while a non-significant effect was recorded by sodium nitrite compared with control. Regarding the histological effect, sodium carbonate and sodium nitrate had the same effect on ovotestis, as a necrobiotic change was observed in the ova, and diminishing in spermatozoal concentration, while sodium benzoate caused decreasing in spermatozoal concentration without any alteration in the ovarian compared with control. Regarding the field results, sodium carbonate and sodium nitrate achieved 78.4 and 79.0% reduction in land snail populations, respectively, compared with 75% for methomyl compound. Conclusions The tested inorganic salts have highly toxic effect against the land snail, M. vermiculata, and they can be used in field control programs, after conducting more studies on their effect on the soil and other environmental components.

Study of the Bactericidal Effect Clove, Cinnamon, and Sodium Benzoate in the Haden Mango and Melon Preservation

An experimental study was conducted to determine inhibition and / or destruction of pathogens in the following; Controls, M-EC, MS, Me-EC, Me-S, Treatments M-EC-LC, LC-MS, LC-EC-I, Me-S-CL, M-EC-C, M-S-C, Me-EC, Me-SC, M-EC-B, M-S-B, Me-EC-B and Me-S-B. Where: M = mango, Me = melon, EC = Escherichia coli, S = Salmonella sp, CL = clove, C = cinnamon, B = sodium benzoate. Qualifying each treatment according to the bactericidal power, as: non-effective, minimum, and fulminant lethal effect on days 0 (t0), 7 (t7) and 15 (t15); the bactericidal effect of aqueous extracts of cinnamon, clove in concentrations of 2.5% and sodium benzoate at concentrations permitted by FDA 0.1% was evaluated using the method of quantification or counting of forming colony units (FCU), on two bacterial strains, Escherichia coli and Salmonella enteritidis, were inoculated in samples of tropical fruits, mango Haden (Mangifera indica) and Cantaloupe melon (Cucumis melo). The bactericidal effect of clove was different in the two fruits treated; in the mango inoculated with E. coli was observed a minimal effect and in the other hand, the sample inoculated with Salmonella spp. there was no bactericidal effect. In the melon sample inoculated with both bacteria, the bactericidal effect of clove was observed. The effect of cinnamon was minimal in both fruits inoculated with E. coli. In the mango inoculated with Salmonella spp. there was no bactericidal effect. In the melon, it was a lethal effect. The use of sodium benzoate had a bactericidal effect, in both, the mango and in the melon inoculated with both bacteria. The analysis found that the mango inoculated with E. coli had a devastating effect (death at day 0). Dry matter, matter balance and sensory analysis were determined to have a better conclusion of the investigation.

Propionic Acid and Sodium Benzoate Affected Biogenic Amine Formation, Microbial Community, and Quality of Oat Silage

Investigating the microbial communities and biogenic amine (BA) formation in silage is of vital for improving the quality and safety of oat silage. The present study evaluated the effects of propionic acid (P) and sodium benzoate (SB) on the quality properties, microbial communities, and BA formation in oat silage. Oat was harvested at boot stage and ensiled using P and SB as additives in mini silos, followed by 14 days of aerobic exposure. The results showed that P and SB improved fermentation quality of oat silage, increased the lactic acid content, and decreased pH value and ammonia nitrogen content. Putrescine, cadaverine, and tyramine were the dominant BAs in oat silage; spermidine and spermine were not detected. The control silage had the highest content of total biogenic amine (TBA, 2506.7 mg kg–1 DM), and decreased by 51.1 and 57.7% after adding P and SB, respectively. Moreover, a lower putrescine, cadaverine, and tyramine content and undesirable microbes, such as Caproiciproducens, Stenotrophomonas, Herbinix, and Enterobacter genera, were observed in P and SB silages, which was beneficial for oat silage quality. The fungal community of P silage was dominated by Monascus fuliginosus, and the temperature, pH and ammonia nitrogen content increased after exposure to air. Sedimentibacter, Herbinix, Caproiciproducens, Enterobacter, and Escherichia-Shigella were found to be positively correlated with BA formation in oat silage. Overall, P and SB effectively inhibit the undesirable microbes and BA formation in oat silage, the P silage exhibited lower aerobic stability than the SB silage.
