Xanthones are significant bioactive compounds and secondary metabolites in mangosteen pericarps. A xanthone is a phenolic compound and versatile scaffold that consists of a tricyclic xanthene-9-one structure. A xanthone may exist in glycosides, aglycones, monomers or polymers. It is well known that xanthones possess a multitude of beneficial properties, including antioxidant activity, anti-inflammatory activity, and antimicrobial properties. Additionally, xanthones can be used as raw material and/or an ingredient in many food, pharmaceutical, and cosmetic applications. Although xanthones can be used in various therapeutic and functional applications, their properties and stability are determined by their extraction procedures. Extracting high-quality xanthones from mangosteen with effective therapeutic effects could be challenging if the extraction method is insufficient. Although several extraction processes are in use today, their efficiency has not yet been rigorously evaluated. Therefore, selecting an appropriate extraction procedure is imperative to recover substantial yields of xanthones with enhanced functionality from mangosteens. Hence, the present review will assist in establishing a precise scenario for finding the most appropriate extraction method for xanthones from mangosteen pericarp by critically analyzing various conventional and unconventional extraction methods and their ability to preserve the stability and biological effects of xanthones.

The present review article is intended to provide comprehensive insights into the techniques of sunflower cultivation, methods of processing, and opportunities for value addition through a variety of applications. Sunflower (Helianthus annuus L.) is an economically valuable crop, admired for its vibrant yellow flowers and seeds rich in high-quality oil. The oil derived from sunflower seeds is nutritionally valued for its high content of unsaturated fatty acids, such as linolenic and linoleic acids, which help to reduce cholesterol levels and prevent arterial fat clots. Moreover, it contains essential vitamins A, D, E, and K. Sunflower cultivation primarily occurs in warm regions, aligning with the plant’s climatic preferences. As a short-lived plant, sunflowers demonstrate drought resilience due to their deep root system. In recent years, the use of sunflowers has significantly expanded, driving economic growth. The demand for products derived from sunflowers, including sprouts, roasted seeds, seed oil, and even sunflower-based agricultural tourism, has increased exponentially. Notably, sunflower seeds and their oil hold particular importance as they form the basis for integrated production systems, contributing to the creation of various food and non-food products. By presenting this information, we aim to provide a comprehensive guide for those interested in enhancing the utilization of sunflowers across various sectors.

The calamondin (Citrofortunella microcarpa) is a hybrid citrus fruit resulting from the crossing of a mandarin orange with a kumquat. It is a small, round-shaped fruit with thin, smooth skin ranging from orange to dark red. The aroma of the fruit is distinctive and unique. Calamondin is an excellent source of Vitamin C, D-Limonene, and essential oils, providing benefits to the immune system, as well as anti-inflammatory, anti-cancer, anti-diabetic, anti-angiogenic, and anti-cancer properties, and it exhibits various therapeutic effects. It also contains a good amount of dietary fiber from pectin. Its distinctive flavor and high juice content make calamondin juice a popular ingredient in many international cuisines. The juice also contains bioactive compounds, such as phenolics and flavonoids, which are a potential source of antioxidant properties. All parts of the calamondin fruit, including the juice, pulp, seeds, and peel, can be used in various applications, from food products like juices, powders, and candies to non-food uses in herbal medicine and cosmetics, showcasing their versatility and unique properties. This review will examine various bioactive components of calamondin and their related medicinal effects, and provide guidelines for their utilization, processing, and value addition on a commercial scale.

This study aims to foster a guideline for sustainable supply chain management for edible insect production through a comprehensive review and critical analysis of the current situation, focusing especially on Thailand’s perspective. It addresses the traditional culture and modern practice of insect consumption and how these factors affect current production for commercial purposes. The advantages of nutritional values and farming with edible insects over traditional livestock farming are highlighted. A threats, opportunities, weaknesses, and strengths (TOWS) matrix analysis, producing action-oriented strategies, was based on an analysis of the strengths, weaknesses, opportunities, and threats (SWOT) of Thailand’s edible insect industry. The strategies include enhancement of production and product quality, innovation of intelligent production techniques and agriculture, fortification of branding and product development, encouragement of research and development investment, and the promotion of local product identity. The analysis emphasizes the value of sustainable supply chain management and advocates for the advancement of the bio-circular green (BCG) economy strategy for the edible insect industry. It also emphasizes the importance of stakeholder collaboration and implementing regulations to ensure food safety and sustainable production.

Khao Mak is a sweet fermented rice-based dessert with a unique flavor profile commonly found throughout Thailand. The traditional starter culture (Look Pang) contains yeast, mold and herbs, which is used to ferment cooked glutinous rice. This research studied production of Khao Mak which resulted in volatile flavor compounds that were affected by rice varieties, including white glutinous rice (Kor Khor 6), Japanese rice (Hitomebore) and black glutinous rice (Kam Doi and Leum Phua). Total soluble solids (TSS) as degree Brix, pH, and alcohol concentrations were measured daily during the fermentation period. Volatile flavor compounds were separated and identified by gas chromatography mass spectrometry (GC-MS). At the end of the fermentation, samples had pH ranging from 3.91±0.16 to 4.30±0.09, total soluble solids of 32.65±1.65 to 44.02±1.72°Brix, and alcohol concentrations between 0.33±0.03 and 0.38±0.03% (v/v). The potent odors associated with Khao Mak were alcohol, wine-like, whiskey-like, solvent-like, sweet and fruity. The major volatile compounds, which have stimulant flavor in Khao Mak, included 1-propanal, 1-propanol-2-methyl, 1-butanal-3-methyl and acetic acid ethyl ester. Among all rice varieties tested, the white glutinous rice produced Khao Mak containing the highest TSS, alcohol concentrations followed by Hitomebore rice and black glutinous rice, respectively.
