Effects of Preliminary and Preservation Methods on the Quality of Radix et Rhizoma Salviae miltiorrhizae | Chapter 6 | Current Research Progress in Agricultural Sciences Vol. 4

Preliminarily preparing and preserving Radix et Rhizoma Salviae mitiorrhzae  (Danshen) has been done for a long time. However, the processing method is simple, manual and based on experience. The effect of pretreatment, drying and storage methods on maintaining the quality of Rhizome and roots of Salvia miltiorrhiza Bunge postharvest was studied. The purpose of the study is to reduce the effect of fungi, maintain the quality of medicinal plants after storage time, limit the increasing of moisture content, keeping a good sensory quality by using organic acid in combination with low pressure. Salvia miltiorrhiza Bunge grown in Hoa Binh is harvested with enough growing time and highly active elements. The experiments used organic acids as acid citric and sodium bisulfate solutions to evaluate the pretreatment of Radix et Rhizoma Salviae mitiorrhzae. Danshen were pretreated and dried by convection drier and heat pump drier and were preserved by low-pressure. The results showed that dipping acid citric solution pH 2.5-3 for 30 minutes restricted the development of total microorganisms. Using a heat pump drier resulted in good sensory quality and retaining tanshinone IIA, salvianolic acid content in Radix et Rhizoma Salviae mitiorrhzae. The method of preserving Radix et Rhizoma Salviae mitiorrhzae by the low pressure of 200 mmHg, and 400 mmHg after 9 months at ambient temperature (25-30 oC), humidity (80-85%) maintained better quality than the control. Besides, the moisture medicine, tanshinone IIA, salvianolic acid content, and total microorganisms in the experiment samples changed slowly during the storage period.

Optimization of Modified Media & Comparative Production of Citric Acid by Aspergillus niger | Chapter 8 |Innovations in Microbiology and Biotechnology Vol.4

 Aspergillus niger was used for submerged citric acid synthesis to study high yield citric acid producers other than citrus fruits. In a comparison investigation, rice and potato extracts were employed as substrates to see which one provided the best yield. Various doses of Sucrose, Glucose, and Nitrogen supplements were used to track changes in citric acid synthesis output. Titration of citric acid extracted from various medium was used to assess the concentration of citric acid produced. To establish the ideal conditions for enhanced citric acid production output, a comparison study was done. By collecting soil samples from the Garden of Dayanand Science College in Latur, Maharashtra, and isolating citric acid-producing fungi (Aspergillus niger) on PDA medium as pure culture, as well as cultivation on modified broth medium, this study can provide a better approach for large-scale industrial production of citric acid, which is one of the most widely consumed organic acids.

Analysis and Toxicity of Some Heavy Metals and Organic Acids in Ficus carica (Common Fig) in Sulaimani / Kurdistan-Iraq | Chapter 4 | Emerging Challenges in Agriculture and Food Science Vol. 1

 Serpentine soil is made up of minerals high in magnesium, such as chrysotile, lizardite, and antigorite. The fig tree (Ficus carica) is a globally important plant. It is a nutritive food that is also employed in industrial processes. The distribution of heavy metal concentrations such as Nickel, Cobalt, Zinc, and Manganese in different portions of this plant, such as its leaves, stems, and fruits, is investigated in this study. The organic acid content, which included citric acid, fumaric acid, malic acid, and oxalic acid, was also calculated. The researched location is Kunjirin, a village in Mawat town located in the northwest extension of the Zagros-fold-thrust belt. Kurdistan Region of Iraq, north-east of Sulaimani Province. Except for zinc, the results demonstrate that there are considerable disparities in heavy metal levels among plant organs. The fruits have the lowest concentration of heavy metals, whereas the leaves have the highest concentration. Furthermore, the organic acids were distributed unevenly throughout the plant organs. The stem, on the other hand, had the lowest level of organic acid, whilst the fruit region of the plant had the highest concentration of organic acids. The results of this study show that the levels of heavy metals in the fruit are within legally permissible limits. This means that both humans and animals are capable of eating such fruits.
