“Táo mèo” vinegar, a fat-burner famous for its many benefits for the digestive and immune systems, can be consumed as functional drinks. However, “táo mèo” vinegar is still producing mainly in manual-based, small-scaled with the surface fermentation method and containing many hazards. For industrial scales, the application of pectinase during the fruit extraction process has increased the quality of end-products and extraction efficiency, leaving no residue during storage. This research focus on the simultaneous application of two kinds of pectinase: PectinexUltra SP-L and PectinaseUltra Clear, during the extracted processing of “táo mèo”. The results indicated that simultaneously using both enzymes has increased the extractivity of the process to 25 %, and also has increased the amounts of function substances such as vitamin C, polyphenol, sugar, acid, and soluble pectin, compared to not using enzymes. The extractive process using the two enzymes for the fruit extracts is determined as follows: PectinexUltra SP-L is used at  concentration of 0.15 %, temperature is 30 oC for 60 minutes;  followed by  using PectinaseUltra Clear with concentration of 0.1 %, temperature is 55 oC for 60 minutes. The enzyme processing does not interfere with the vinegar fermentation process; vinegar  with  enzyme pretreatment contains higher amounts of polyphenol, vitamin C, and potassium compared to that without enzyme pretreatment. The amount of soluble pectin in vinegar with enzyme pretreatment stays constant with no sediment during six months of storage, whereas vinegar without enzymes pretreatment  produces precipitation afer two months of storage.

Method Of Extraction

Among the significant problems in the sago processing, the extraction of the starch from its trunk tops the list. The extraction process involves a debarking and rasping process that is very tedious, unsanitary and time consuming that dramatically affects the quality of starch production since the local processor relies mainly on conventional method of extraction. This paper presents the design, fabrication and performance evaluation of sago pith extraction machine. The design concept made was to rasp the sago pith using a rotating rasper without debarking the log to minimize the steps on the extraction process. Four different teeth spacing of the rasper were considered during the testing and replicated three times; 1 cm, 2 cm, 3 cm, and no teeth as controlled parameters, respectively. Results revealed that teeth spacing has a significant effect on the performance of the machine such as extraction capacity, extraction efficiency and fineness of rasped pith. Based on average, the highest extraction capacity was recorded at 217.47 kg/h using 3 cm teeth spacing, and the highest extraction efficiency was 96.12% using 2 cm teeth spacing and the finest rasped pith having the lowest fineness modulus of 2.15 was when 1 cm teeth spacing is used. Compared to manual and other existing mechanical rasper accounting the process of debarking, machine’s extraction capacity is higher, more efficient, safer and hygienic. Cost and benefit analysis supports that the machine is profitable and the financial efficiency is high having a 65% rate of return and 1.8 years payback period.

Ethnopharmacology experts face several challenges when identifying and retrieving documents and resources related to their scientific focus. The volume of sources that need to be monitored, the variety of formats utilized, and the different quality of language use across sources present some of what we call “big data” challenges in the analysis of this data. This study aims to understand if and how experts can be supported effectively through intelligent tools in the task of ethnopharmacological literature research. To this end, we utilize a real case study of ethnopharmacology research aimed at the southern Balkans and the coastal zone of Asia Minor. Thus, we propose a methodology for more efficient research in ethnopharmacology. Our work follows an “expert–apprentice” paradigm in an automatic URL extraction process, through crawling, where the apprentice is a machine learning (ML) algorithm, utilizing a combination of active learning (AL) and reinforcement learning (RL), and the expert is the human researcher. ML-powered research improved the effectiveness and efficiency of the domain expert by 3.1 and 5.14 times, respectively, fetching a total number of 420 relevant ethnopharmacological documents in only 7 h versus an estimated 36 h of human-expert effort. Therefore, utilizing artificial intelligence (AI) tools to support the researcher can boost the efficiency and effectiveness of the identification and retrieval of appropriate documents.

A novel microwave assisted multi-stage countercurrent extraction (MAMCE) technique was developed for the extraction of dihydromyricetin from Chinese rattan tea, Ampelopsis grossedentata. The technique combined the advantages of microwave heating and dynamic multi-stage countercurrent extraction and achieved marked improvement in extraction efficiency over microwave assisted batch extraction. Analysis of dihydromyricetin concentrations in the solvent and matrix throughout the extraction process showed that by dividing the extraction into multiple stages and exchanging of solvents between stages, steady and substantial concentration gradients were established between the matrix and solvent, thus enabling the achievement of high extraction efficiency. The yield of dihydromyricetin was significantly affected by temperature, pH, solvent/material ratio and extraction time, and optimal extraction conditions were found to be 80-100°C, at acidic pH with a solvent/material ratio of 25-30 to 1 and extraction time of 5-10 min. With the high extraction efficiency and low usage of extraction solvent, MAMCE could prove to be a promising extraction technique which can be applied to the extraction of dihydromyricentin and other bioactive substances from natural materials.

Changes in mango fruit quality, malondialdehyde content, and enzymatic activities in response to pathogen Alternaria alternata infection were studied. A. alternata significantly affected the appearance of mango fruit at 5 and 7 days after treatment (DAT). The quality of pathogen-infected fruit first showed a significant decrease in titratable acidity and vitamin C content and a significant increase in pH since 3 DAT. The malondialdehyde content was higher than that in the untreated controls at 3 and 7 DAT. The enzyme activities of ascorbate peroxidase and polyphenol oxidase showed significant increases since 3 DAT. Significant increases in l-phenylalanine ammonia-lyase and superoxide dismutase activities were observed at 7 DAT. These results indicate that A. alternata infection first significantly affects some biochemical constituents and enzyme activities in mango fruit since 3 DAT and that there was no significant effect on appearance until 5 DAT.

High Pressure Homogenization

High-pressure homogenization (HPH) is one of the food-processing methods being tested for use in food preservation as an alternative to pasteurization. The effects of the HPH process on food can vary depending on the process parameters used and product characteristics. The study aimed to investigate the effect of pressure, the number of passes, and the inlet temperature of HPH processing on the quality of cloudy blackcurrant juice as an example of food rich in bioactive compounds. For this purpose, the HPH treatment (pressure of 50, 150, and 220 MPa; one, three, and five passes; inlet temperature at 4 and 20 °C) and the pasteurization of the juice were performed. Titratable acidity, pH, turbidity, anthocyanin, vitamin C, and total phenolics content, as well as colour, and antioxidant activity were measured. Heat treatment significantly decreased the quality of the juice. For processing of the juice, the best were the combinations of the following: one pass, the inlet temperature of 4 °C, any of the used pressures (50, 150, and 220 MPa); and one pass, the inlet temperature of 20 °C, and the pressure of 150 MPa. Vitamin C and anthocyanin degradation have been reported during the HPH. The multiple passes of the juice through the machine were only beneficial in increasing the antioxidant capacity but negatively affected the colour stability.
