Limau (Citrus amblycarpa (Hassk.) Ochse) is one of the native Citrus species of West Java that is grown in the local backyard, thus is easily found in local cuisines. Limau has great potentials for use as a potted plant in home gardens for its aesthetic value and fragrance. The objective of this research was to describe the metabolites fingerprint and morphology of Limau as a potential functional and ornamental mini tree. Methanol leaf extracts from one-year-old Limau originated from Bogor were analyzed using untargeted Gas Chromatography Mass Spectrometry (GCMS). Methanol leaf extract was dominated by vitamin E and composed of other 18 metabolites including phytosterols, fatty acids and terpenes. The major portion of fruit extract consisted of 6-octadecenoic acid, palmitate and various fragrance compounds such as alpha sinensal, alpha limonene, beta citronellal, citronellol, and sabinene. Limau fruits are also a functional food due to its rich antioxidant and aromatic content in the fruits. The morphology of limau tree is suitable as a potted ornamentals or mini-fruits tree for its small crown, sparse branching with unifoliate aromatic leaves and small spines, and plentiful aromatics mini fruits with the diameter of around 2-4 cm.

Root is the important plant organ hiding below the soil that serves as plant supporting structure, water and nutrient supplier and assimilates storage. Root growth occurs in turn with shoot part, forming repeated cyclic pattern because of the photosynthate competition. Root growth regulation is one of the promising practices to boost the yield of fruit tree, especially citrus that is economically important and highly demanded fruit. Root pruning varied based on the scale of intensity and plant growth stage, including air root pruning, knife root pruning and modern pruning using root pruner machine mounted to a tractor. Root pruning to induce the growth of more fi brous root system and to correct root deformation at seedling stage have potentials to improve post-transplant growth. Besides, it has a potential to replace the use of chemical plant growth regulator for a more environmentally friendly practice. The pruning of root impeded the canopy growth, altered the plant water status leading to fl ower promotion. In addition, it is also a promising practice to overcome the alternate bearing on fruit tree, including citrus, through the suppressing of excessive growth and restricting the high fruit load during the ‘on year’ and allowing a better carbohydrate storage for the improvement of yield during the ‘off year’.

Kaffir lime (Citrus hystrix DC) is one of the Citrus species that is popular as food spices in Indonesia. This study was aimed at describing the production system, post-harvest handling, marketing and evaluating the product variation of kaffir lime cultivated in the Tulungagung district, East Java Province, Indonesia. Data was collected through a survey by interviewing kaffir lime farmers, distributors and customers in June 2018. Kaffir lime is cultivated by local farmers using traditional and conventional agriculture practices. The farmer used good quality seedlings as planting materials and applies animal manure or compost to the trees. Kaffir lime is grown on rain-fed land; fertilizers and pesticides are applied sparingly. The kaffir lime leaves could be harvested twice a year in different seasons. Better leaf quality can be obtained during the rainy seasons. The leaf production per tree is estimated at about 100 gram per plant per season. Post-harvest handling involved sorting, packing and marketing without any cooling treatment. The standard gate price of kaffir lime leaf in June 2019 was IDR 6,000-7,000, IDR 9,000-10,000 at the collector level, IDR 11,000-12,000 at wholesaler, and IDR 14,000-16,000 at small retailers. Leaves were distributed to traditional market in Tulungagung, neighbouring districts such as Kediri, Trenggalek and Blitar, and also to capital cities such Jakarta. The main product of kaffir lime is the fresh leaf for food seasoning and as a raw material to produce essential oil and dry leaf powder. The stems have been used for fuel in home industries. The fruits of kaffir lime are rarely found in the market and have great potentials for essential oil production and recently, a promising commodity for export.

This study aimed to evaluate the sensory attributes such as aroma, color and texture of kaffir lime leaves in response to various post-harvest treatment. The hedonic test approach was conducted by inviting 70 untrained panelists on seven post-harvest treatments, i.e. (D1) post-sortation fresh leaves, (D2) pre-sortation fresh leaves, (D3) cold-storage leaves, (D4) low temperature-storage leaves, (D5) brown dry leaves, (D6) fresh leaf-flour, and (D7) brown dry leaf-flour. The result showed that most of panelist agreed that aroma was the most important quality attribute that determined the level of preference in kaffir lime leaf products. Among seven tested products, the aroma, color, texture and overall impression of D1 was the most favorite one, while D4, D5, and D7 were assessed as low preference products. This work showed the importance of sortation and cold storage to maintain consumer likeliness. The criteria for sortation were green, clean, pest-disease free, scar free, high uniformity and fresh condition of leaves. Cold-storage at -20oC maintained the color and texture of kaffir lime leaves better than low temperature storage (5oC). To make leaf flour, the use of fresh green leaves was significantly better than brown dry ones. This finding might become the baseline data for the development of kaffir lime leaf product in the future.

Fruit quality is an important aspect that requires attention and more study when it comes to commercializing tropical fruits, including guava ‘Kristal’. This study aimed to evaluate the effect of bagging treatment and altitude of growing orchard on fruit quality of guava (Psidium guajava var. ‘Kristal’). This study was conducted at two local orchards managed by small-scale farmers, at Gunung Batu (1000 meters above sea level, m asl) and Brajaselebah (25 m asl), Lampung Province, Indonesia. A nested design was applied to test 5 types of bagging treatments and 2 levels of land altitude. Fruit quality was assessed by measuring both physical and chemical characteristics. Fruit size indicated by fruit weight and diameter was significantly larger in lowland compared to highland. The total soluble solids (TSS) were significantly higher in the lowland compared to the highland, while titratable acid (TA) showed an opposite result. Vitamin C of the fruits varied from140 to 146 mg per 100 g. Different types of fruit bagging and land altitudes did not affect the physical and chemical characteristics of “Kristal” guava fruits. Fruit scar intensity was higher in lowland, especially in fruit without bagging. Fruit bagging is highly recommended for farmers due to the success of this treatment to reduce fruit scar intensity, thus resulting in good fruit quality, irrespective of the growing locations.

Kaffir lime (Citrus hystrix DC) is a less popular citrus species commonly used as a food spice and a source of essential oil. Early studies report the success of preharvest mild shading to increase leaf yield, although there is still limited information on the effect of preharvest shading on the quality of essential oil produced. The aim of this current study is to evaluate the effect of preharvest mild shading factors on the yield, physical characteristics, and metabolite fingerprinting of kaffir lime leaves essential oil (KLLEO). One-year-old kaffir lime trees were sampled in two preharvest treatments, i.e., open sun and mild shading (24% light reduction) at Pasir Kuda experimental field, Bogor, Indonesia. Statistical analysis showed that there was no significant effect of preharvest treatment on yield and physical characteristics (color, specific gravity, and refractive index) of KLLEO. In contrast, there was a metabolite fingerprinting variation of KLLEO as an effect of mild shading. The relative percentage of bergamol, citronellol, caryophyllene oxide, citronellic acid, isopulegol, isopulegyl formate, limonene, linalool, and linalool oxide was increased by mild shading. On the other hand, the main metabolite (citronellal) was significantly reduced by about 10% in shading treatment, as compared to the open-sun ones.

Citrus is popularly known as the source of beneficial and essential nutrients for human health, including vitamins. The current review revealed the content of multivitamins, not only vitamin C but also vitamins A, B, and E that are not widely acknowledged within Citrus. Numerous Citrus genotypes contain vitamin C, with the grapefruit (Citrus paradisi) being the richest, and citron (C. medica) the poorest. Vitamin A in the form of β-carotene, α-carotene, and β-cryptoxanthin is commonly found within Citrus, especially in several colored flesh species such as grapefruit, mandarin (C. reticulate), and orange (C. sinensis). In terms of vitamin B, orange and grapefruit are proven to contain B-complex, including thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), inositol (B8) and folate (B9). Vitamin E in the form of α-tocopherol was detected in leaf kaffir lime (C. hystrix) and orange (C. sinensis), lemon (C. limon), mandarin (C. reticulate), and tangerine (C. nobilis) fruit. This review summarizes the nutritional content of Citrus; Citrus contains not only vitamin C but also other vitamins beneficial to human health, therefore Citrus consumption is highly recommended.

The importance of kaffir lime leaf as essential oils (EOs) raw material is starting to get attention because of its commercial value; however, there is no quality reference for kaffir lime leaf EOs, especially in response to various post-harvest handlings. This study aimed to describe the physicochemical characteristics and yield of kaffir lime EOs subjected to different post-harvest. Bogor originated-kaffir lime leaf was prepared to be subjected to several post-harvest treatments, i.e., control/fresh green leaves (P1); milling to produce green leaf flour (P2); drying to produce dry brown leaf (P3), and milling and drying to produce brown leaf flour (P4). The result showed that post-harvest treatment generally decreases an oil yield and increases darkness color, specific gravity and refractive index of tested EOs. Additionally, post-harvest treatment also changes metabolite profile revealed by GCMS analysis. The relative percentage of caryophyllene and citronellol tends to increase, while the linalool and citronellal levels decrease due to tested post-harvest treatment. It was implied that for the benefit of the fragrance industry with a high citronellal requirement, EOs should be made from fresh green leaves and the leaves should be avoided from drying and powdering treatment.
