Protective Effect of Bee Pollen In Acute Kidney Injury, Proteinuria, And Crystalluria Induced By Ethylene Glycol Ingestion In Rats

Oxidative stress plays a role in hyperoxaluria-induced kidney injury and crystallization. Bee pollen is a hive product with a high content of antioxidants. The antioxidant content and protective effect of bee pollen extract (BPE) against ethylene glycol (EG) induced crystalluria and acute kidney injury (AKI) were investigated. Ten groups of male Wistar rats were treated with EG, cystone (500 mg/kg) or BPE at doses 100, 250, and 500 mg/ kg. On day 30, blood and urine samples were collected for analysis. Kidneys were removed for histopathological study. The antioxidant activity of BPE was assessed, and its total phenols and flavonoids were determined. EG significantly increased urine pH, volume, calcium, phosphorus, uric acid, and protein, and blood urea, creatinine, and liver enzymes (P<0.05). It decreased creatinine clearance and urine magnesium and caused crystalluria. Treatment with BPE or cystone mitigates EG's effect; BPE was more potent than cystone (P<0.05). BPE increases urine volume, sodium, and magnesium compared to the control and EG treated groups. BPE reduces proteinuria and prevents AKI, crystalluria, liver injury, and histopathological changes in the kidney tissue caused by EG. BPE might have a protective effect against EG-induced AKI, crystalluria, and proteinuria, and stone deposition, most likely by its antioxidant content and activity.

Use of wheat flour and spent coffee grounds in the production of cookies with high fiber and antioxidant content: Effects of spent coffee grounds ratio on the product quality

Spent coffee ground (SCG) is the main by-product of the instant coffee industry. In this study, wheat flour and dried SCG powder were used in the production of cookies with high fiber and antioxidant content. The objective of the study was to evaluate the effects of SCG ratio in the cookie formulation on nutritional quality, physical properties and sensory overall acceptability of the product. SCG is a rich source of dietary fiber. In 100 g dry weight of SCG, the total fiber and phenolic contents were 76.6 ± 0.58% and 3828±12 mg GAE/100g dry basis, respectively. When the SCG ratio increased from 0 to 0.25 of the composite flour weight, the dough had increased hardness and reduced adhesiveness, cohesiveness and springiness. An increase in the SCG ratio in the cookie formulation also decreased the diameter and thickness of the product but enhanced its hardness. Cookie samples supplemented with SCG had higher dietary fiber and phenolic content as well as a higher antioxidant activity than the control sample. Cookie samples were considered as high fiber food when the SCG ratio was 0.1 or higher. The use of SCG reduced the overall acceptability of cookies. When the ratio of SGC powder varied from 0.1 to 0.2, a sensory score of the obtained cookies was acceptable.

The first stage was kencur cultivation in the AgroTechno-Park UB in Jatikerto from November 2020 to June 2021 designed according to the Split-split plot design (3 factor treatments). The main factor was the shade, sub plots were accession of kencur, and t doses of potassium fertilizer. The second stage was conducted in the Plant Physiology Laboratory to analyze the antioxidant content after the field experiment. The results showed that there was increased antioxidant activity in kencur rhizomes due to the use of potassium fertilizer and shade. The 25% shade produced higher antioxidants than 50% shade in both Lumajang and Nganjuk’s accessions.

Proximate and Sensory Analysis of Functional Drink from Jackfruit Seed Extract with Citrulline Fortification As A Potential Antidiabetic

The World Health Organization (WHO) predicts that diabetes Mellitus in Indonesia by 2030 will increase to 21.3 million people. There was a growing need for natural foods that can be used as a substitute for antihyperglycemic drugs and may lower the blood sugar levels of diabetes Mellitus patients without burdening the kidneys and causing other side effects. Citrulline, one of the amino acids that are useful for the immune system and improving blood flow circulation, is found in the white peel of watermelon in greater levels compared to the citrulline content of other fruits. Previous research has shown that citrulline supplementation significantly lowered fasting blood sugar and HbA1c as well as inflammatory biomarkers, including in obese subjects. Methods conducted in this study include watermelon peel extract making, jackfruit seed drink making, proximate analysis, total phenol testing, organoleptic testing, and data analysis. The results of proximate testing on jackfruit seed drink with additional citrulline (F1) were F1 samples consisting of 92.31% water, 0.47% protein, 0.99% fat, 0.00% ash, and 6.23% total carbohydrates. Sensory analysis revealed that the flavor of the drink was disliked, while the aroma of the drink was somewhat liked. The addition of watermelon peel extract in jackfruit seed drinks may increase nutrition value, antioxidant content, and has the potential to be a functional drink with antioxidant content and blood sugar reduction effects as antidiabetics.

Investigation of Nutritional and Antioxidant Properties of Anatolian Bee Bread

Bee bread is a bee product produced by bees in which they combine pollen with their digestive enzymes and place them in the comb cells. In this study, it was aimed to evaluate the nutritional and antioxidant properties of Anatolian bee bread and present an examination of regional differences. In order to emphasize the bioavailability of bee bread and to determine its phenolic, flavonoid content, antioxidant activity and nutritional quality, ten samples were collected from different parts of Anatolia. Seven of them were from Muğla (prominent city in terms of honey production), one was from Van representing the Eastern Anatolia region, one was from Sivas representing the Central Anatolia region and one was from Kırşehir. Ten samples were analyzed for total phenolic, flavonoid, antioxidant and moisture content, and the mixture representing ten samples were analyzed for nutritional content (carbohydrate, fat, saturated fat, fiber, protein, salt, ash, iron and zinc). Total phenolic content, flavonoid, antioxidant content and moisture content of the samples were determined as 11.90 – 14.77 mg GAE/g, 1.30 – 6.30 mg CE/g, 20.03 – 35.43 mg TEAC/g and 10.13 – 18.10%, respectively. The highest phenolic, flavonoid and antioxidant content was observed in Muğla2 samples. The study’s results were compared to results found in literature, and it was concluded that Anatolian bee bread has high antioxidant content and nutritional value, especially, in terms of carbohydrates, iron and zinc.

Antioxidant capacity of snack cookies made from mango and pineapple fermentation

Mango (Mangifera indica) and pineapple (Ananas Comosus) are tropical fruits that contain many nutrients, one of which is antioxidants and polyphenols. Lots of studies have shown that fermented fruit is higher in antioxidants and health benefits. Antioxidants have been reported to be an alternative to enhance body immunity and possibly become an Anti -SARS-CoV-2. One of the antioxidants that are easily found in vitamin C. This study is to process the fermented mango and pineapple fruits into cookies and to test the antioxidant content (especially Vitamin C) in vitro. There were three variations of the formulation, mango: pineapple: CO2 free water. Sample 1 (1: 0.5: 0.5), sample 2 (2: 1: 1) and sample 3 (3: 2: 2). Then, all product samples were inoculated with Lactobacillus paracasei 5% b/v for 14 days under anaerobic conditions to get simpler mangoes and pineapple food fibre. The fermented products were made into flour with a freeze dryer. Sample variation is done to determine the average significance of the antioxidant content in it. The next step was Vitamin C analysis from 3 samples of cookies sample using Titration Iodometric Method, to determine the amount of Vitamin C (mg/100 g) and also the antioxidant activity with 2,2-diphenyl-1-picrylhydrazyl (DPPH). The amount of vitamin C obtained in Sample 1 was 100.20 mg/100 g respectively with antioxidant activity is 35.33%. Sample 2 was 95.75 mg/100 g respectively with antioxidant activity is 30.60%. Sample 3 was 107.90 mg/100 g respectively with antioxidant activity is 44.70%. The formulation with the highest amount of cookies sample containing vitamin C is S3. There was a significant difference (P<0.05) that determined vitamin C levels between sample formulations. The mean ash content of the three samples was 2.02±0.04% and water content were 1.60± 0.15%. The average vitamin C levels in the three sample cookies were 101.28±6.14 mg/100 g. Sample 3 indicated the best antioxidant activity towards 2,2-diphenyl-1- picrylhydrazyl (DPPH) in the amount of 44.70%. Therefore, fermented mango and pineapple have a great potential to be developed into healthy snack cookies. The vitamin C and antioxidants content in cookies from the fermentation of mango and pineapple may be a great substitute for snacks since antioxidants has the ability to improve immunity and anti-inflammatory response. These cookies are also good prebiotics for the gut microbiome which plays a good role in the immune system.
