“…The total PPN content in the M. citrifolia extract was determined by using Folin–Ciocalteu method ( Ab Rahman et al, 2019 ) with modification using gallic acid as the standard. Each 0.5 mL sample added 0.5 mL distilled water and one mL of Folin–Ciocalteu reagent, stood for 5 min.…”

The increasing popularity of Morinda citrifolia has many medical and health benefits because of its rich polysaccharides (PSC) and polyphenols (PPN). It has become popular to brew the dry M. citrifolia fruit slice as tea in some regions of China. In this study, optimize the extraction parameters of M. citrifolia fruit tea polysaccharides and polyphenols using response surface methodology. The results indicated the highest PSC yield of 17% at 46 °C for 11 min and the ratio of water/M. citrifolia fruit powder was 78 mL/g. The optimum extraction of PPN was at 95 °C for 10 min and the ratio of water/M. citrifolia fruit powder 90 mL/g, with 8.93% yield. Using dry M. citrifolia fruit slices as a tea is reported for the first time. Based on the results, the maximum level of PSC can be obtained under condition by infusing about four dried M. citrifolia fruit slice with average thickness and size in warm boiled water for 11 min, taking a 300 mL cup (300 mL of water) for example. The maximum level of PPN can be obtained by adding three slices of dried M. citrifolia fruit slice to boiled water for 10 min. Considering the powder used in our study, the further pulverization of cutting into powder is more conducive to material precipitation. This study provides a scientific basis for obtaining PSC and PPN from dry M. citrifolia fruit slice tea by brewing.

“…Most of the previous studies were on agronomy, phytochemicals, nutrient composition, downstream application, and postharvest management of the crops (Razili et al, 2013;Shariah et al, 2013;Rahman et al, 2019). To date, there are no records of insects associated with the S. lasiocarpum due to limited study for pests and beneficial insects for this indigenous species.…”

Solanum lasiocarpum (Solanaceae), commonly known as Terung Asam, is an indigenous crop in Sarawak, Borneo. The S. lasiocarpum is a renowned crop and is significant to the local and smallholder farmers for their household income. Study of insects associated with this crop is currently limited and lacking, despite their importance for Sarawak’s agronomy. Hence, this study aimed to determine the associated insect species with S. lasiocarpum throughout the plant growth, namely, vegetative, flowering, and fruiting phases. Henosepilachna kaszabi (Coccinellidae) and mealybug Pseudococcidae were recorded as primary pests, while Anoplolepis gracilipes (Formicidae) and Polyrhachis sp. (Formicidae) as indirect pests for flowering and fruiting phases. Larvae and adults of H. kaszabi were sighted infesting leaves, stems, and roots, while Pseudococcidae congregated and infested the stems of S. lasiocarpum. Other visiting insects for S. lasiocarpum were also listed in this study. This study provides preliminary information regarding the insect pests of S. lasiocarpum for future effective pest management on this crop.

SummaryThe local people of Sarawak commonly made unique dishes out of the local distinctive resources for its health beneficial nutrients. Yet, many potentials of the local Sarawak food ingredients are less likely to be exploited. One of the main produces of Sarawak is the starch from Metroxylon sagu. Our study reviewed that sago starch is not only active in health beneficial bioactivities such as antioxidative, it also possesses positive prebiotic response. Other local indigenous fruits, vegetable and spices of Sarawak as potential functional food includes Sarawak pepper; midin, the edible fern; terung asam, the sour eggplant; dabai, the Bornean olive; engkalak, the Bornean avocado; Terap, the local ‘jackfruit’; embangan, the local wild mango; and the edible palm heart (EPH) from palm tree. Research on the edible fern (midin), edible palm hearts (umbut), spices such as turmeric and pepper from Sarawak has revealed a positive functionality in terms of prebiotic potential, antioxidative, antimicrobial and many more. Conclusively, the wide food varieties of Sarawak are potential functional food. Therefore, this work aimed to publicise the health beneficial functionalities of the local indigenous food which then value‐added the rare local food resources, and boost the local farmer's production and economic status.
