Longkong (Aglaia dookkoo Griff.) fruit is prone to rapid pericarp browning and shortened shelf life (<7 days) under prolonged low-temperature storage. This study investigates the effect of an edible coating, comprising carboxymethyl cellulose (CMC) and gelatin in a fixed 3:1 ratio, integrated with various concentrations of melatonin (MT) (0.4, 0.8, and 1.2 mM/L) to mitigate chilling injury in longkong fruit. Coated longkong fruits were stored at 13 °C with 90% relative humidity for 18 days and underwent physicochemical evaluations every three days. Samples coated with CMC-Gel without MT and uncoated fruits were served as controls. The findings indicated that the CMC-Gel-MT coating significantly mitigated pericarp browning, chilling injury, weight loss, and respiration rate increase under extended cold storage conditions. High concentrations of MT (≥0.8 mM/L) in the coating notably inhibited the activities of cellular degrading enzymes such as lipoxygenase and phospholipase D. This inhibition contributed to reduced membrane permeability, lower reactive oxygen species accumulation (H2O2, OH−, O2−), and decreased malondialdehyde levels in the longkong pericarp. Furthermore, the CMC-Gel-MT coating increased the activity of phenylalanine ammonia lyase, leading to an enhancement in phenolic content. Consequently, it improved the fruit’s ability to scavenge DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,20-azino-di-3-ethylbenzthiazoline sulfonic acid) radicals. Control samples exhibited high levels of pericarp browning-related enzymes (polyphenol oxidase, peroxidase), whereas CMC-Gel-MT-coated fruits, particularly at higher MT concentrations, showed significant reductions in those enzyme activities. In conclusion, incorporating high concentrations of MT in a CMC-Gel-based edible coating is a promising alternative for mitigating chilling injury in longkong fruit.

“…CMC has been reported to have a wide range of benefits, such as increased viscoelasticity, oil/grease resistance, and enhanced coating properties. Gel-CMC biopolymer composites can form transparent edible coatings or films and act as a carrier for active additives such as antioxidants and antimicrobial agents [ 36 , 140 ].…”

Micro-/Nano-Carboxymethyl Cellulose as a Promising Biopolymer with Prospects in the Agriculture Sector: A Review

The increase in the population rate has increased the demand for safe and quality food products. However, the current agricultural system faces many challenges in producing vegetables and fruits. Indiscriminate use of pesticides and fertilizers, deficiency of water resources, short shelf life of products postharvest, and nontargeted delivery of agrochemicals are the main challenges. In this regard, carboxymethyl cellulose (CMC) is one of the most promising materials in the agriculture sector for minimizing these challenges due to its mechanical strength, viscosity, wide availability, and edibility properties. CMC also has high water absorbency; therefore, it can be used for water deficiency (as superabsorbent hydrogels). Due to the many hydroxyl groups on its surface, this substance has high efficacy in removing pollutants, such as pesticides and heavy metals. Enriching CMC coatings with additional substances, such as antimicrobial, antibrowning, antioxidant, and antisoftening materials, can provide further novel formulations with unique advantages. In addition, the encapsulation of bioactive materials or pesticides provides a targeted delivery system. This review presents a comprehensive overview of the use of CMC in agriculture and its applications for preserving fruit and vegetable quality, remediating agricultural pollution, preserving water sources, and encapsulating bioactive molecules for targeted delivery.

“…This could be due to the use of too much sucrose, crystallising the surface of the jam. However, if there is not enough sugar in the jam, it will produce a weaker gel at all acidity levels, so more acid must be added to strengthen the structure [14].…”

The high production of melons in Indonesia is affected by non-optimal post-harvest handling and the accelerated loss of quality due to its abundant water content, which reduce its economic value. The Sky Rocket variety is Indonesia's most widely grown type of melon. The post-harvest handling of melon that has not been implemented is the production of jam. The correct recipe must be determined to produce melon spread, or jam, with good characteristics. This study aims to determine the effects of the sucrose and acidifier on the physicochemical and sensory characteristics of the melon spread and to find the combination of treatments that produce the melon spread with the best physicochemical and sensory characteristics. This study used experimental methods and factorial randomized block design. The observed factors were the concentration of sucrose, 40%, 50% and 60%, and the type of acidifier, citric acid, lime and pineapple. Experiments were performed three times; thus, there were 27 experimental units. The variables observed included water content, acidity (pH), total dissolved solids and vitamin C content, as well as sensory variables such as colour, spreadability, texture, melon aroma, sweet taste and preference. The use of different concentrations of sucrose affected the water content, total dissolved solids, and sensory variables of the melon spread. The type of acidifier affected the physicochemical and sensory variables of the melon spread, except for the total dissolved solids. The interaction between the sucrose and the acidifier only affected the sensory variables. The best treatment combinations were treatment with 50% sucrose and pineapple with a water content of 31.49%, pH 6.90, TPT 71.00°Bx, vitamin C of 114.40 mg/100 g, colour 3.55 (bright green), spreadability 4.05, texture 3.12, melon aroma 3.00, sweet taste 4.23 and preference 3.43.
