The kiwi berry (Actinidia arguta) has been widely studied because of its rich phenolic, flavonoid, and vitamin C contents. Numerous reports have demonstrated that fruit peels contain higher phenolic content and antioxidant activity than that of flesh. In this study, the phytochemical content and antioxidant activities of peel and flesh extracts of six kiwi berries were analyzed from four regions (namely, Dandong, Benxi, Taian, and Tonghua) in China. The antioxidant activity was determined using the peroxyl radical scavenging capacity (PSC) and cellular antioxidant activity (CAA) assays. The phenolic, flavonoid, and vitamin C contents of kiwi berry peel were 10.77, 13.09, and 10.38 times richer than that of kiwi berry flesh, respectively. In addition, the PSC and CAA values of kiwi berry peel were higher than those of kiwi berry flesh. The analysis of the separation and contents of phenolics were performed by the high-performance liquid chromatography (HPLC)-diode-array detectormass spectrometry/mass (DAD-MS/MS) system, and the results illustrated that protocatechuic acid, caffeic acid, chlorogenic acid, and quinic acid were the major phenolic compounds. In conclusion, this study indicated that kiwi berry peel contains a rich source of antioxidants. These data are of great significance for the full development and utilization of kiwi berries in these four regions of China to produce nutraceutical and functional foods.

In traditional Chinese medicine, Aurantii Fructus Immatures (AFIs) have been utilized for more than 2000 years. The proportions of different fruit parts are crucial for evaluating AFI quality in China. However, the basis for this statement’s substance is unclear. Differences in quality are intimately correlated with a plant’s metabolite composition. On the basis of a widely targeted metabolome, this study intended to investigate the metabolite composition and evaluate the antioxidant capacity of the peel and pulp of an AFI. Metabolites were identified and quantified by UHPLC-QqQ-MS. To assess their antioxidant ability, DPPH and ABTS assays were carried out. There were 1327 chemical compounds identified by UHPLC-QqQ-MS. After screening the differential metabolites using a multivariate statistical analysis, it was found that there were 695 significant differences in the metabolites between the peel and the pulp. Among them, it was discovered that the content of active ingredients in the peel group was higher than that in the pulp group. Furthermore, the aqueous extracts from the peel showed stronger antioxidant capacities than those from the pulp. The metabolites and antioxidant capacities were significantly different between the peel and the pulp. This study of different fruit parts might provide a guide for AFI quality assessments.

Defatted seed, pulp and whole fruit of Idesia Polycarpa Maxin. ( I. Polycarpa ) are the by-products of the oil extraction process, but have attracted little attention as natural sources of bioactive phenolics. This study aimed to clarify the profiles of phenolic compounds in the extracts from these by-products and their contribution to the anti-inflammatory activity. Twenty-one phenolic compounds were identified, belonging mainly to salicinoid analogues and p -coumaroyl derivatives. Idescarpin was the predominant phenolics in all extracts, especially in seed extract. Nearly half the p -coumaroyl derivatives presented relatively high content in the extracts of pulp and whole fruit. All extracts inhibited the production of nitric oxide (NO) and the mRNA expressions of inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF-α), and interleukin (IL)-6; and suppressed the accumulation of reactive oxygen species (ROS) along with the restoration of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities. Seed extract exerted better potential than the pulp and whole fruit extracts. Furthermore, correlation analysis demonstrated that idescarpin and idesin were the crucial phenolics against inflammation, whereas some p -coumaroyl derivatives contributed to regulating oxidative stress. These findings suggested that phenolic extracts from defatted I. Polycarpa fruit and its parts, especially seed, could be utilized as inflammation inhibitors in the functional food and cosmetics industries.

The purpose of this study was to compare the accuracy and robustness of the detection models based on bulk optical properties (BOP) with that based on conventional spectroscopy in kiwifruit quality evaluation. 81 kiwifruit were selected as experimental samples in this study. A single integrating sphere system was built to estimate the bulk absorption coefficient ( μ a ) and bulk reduced scattering coefficient ( μ s ′ ) of samples and a self-designed online system was used to obtain transmission spectra. The relationship of μ a and μ s ′ with SSC and flesh firmness was analyzed, and detection models were established using partial least squares regression (PLSR). Competitive adaptive reweighted sampling (CARS) was also used to eliminate the variables in the original spectra that do not contribute to the improvement of the model performance. Results showed that μ a at 670 nm decreased with the increase of SSC, μ a at 720–900 nm and 950–1000 nm increased with the increase of SSC, and spectra of μ s ′ decreased with the decreasing firmness. CARS-PLSR models were developed, based on μ a , μ s ′ , μ a × μ s ′ , μ e f f , μ t ′ , and transmission spectra. The accuracy of the model based on BOP in predicting internal quality was better than that based on transmission spectra. The model based on μ a was the best for SSC ( R p 2 = 0.97, RMSEP = 0.25%), and the model based on μ a × μ s ′ was the best for flesh firmness ( R p 2 = 0.97, RMSEP = 0.02 N). 20 kiwifruit that differed from the experimental samples in planting orchard and harvest time were used to compare the robustness and portability of the models. Results showed that all SSC models and the firmness model based on μ a × μ s ′ had good robustness and portability. However, the model based on transmission spectra had a poor performance in predicting the firmness of samples from the external validation set. This study provides an effective reference for the prediction of firmness and SSC based on BOP and transmission spectra of kiwifruit.

Celiac disease (CD) is a genetic autoimmune disorder of the small intestine, occurring in genetically predisposed people with a prevalence of about 1% in global population. To combat the CD, lifelong adherence to gluten free (GF) diet is required. The GF breads are generally deficient in nutrients such as dietary fiber, antioxidants, vitamins, minerals etc. To overcome this deficiency, GF bread was supplemented with guava pulp powder (GPP) at 5 different level (0, 2.5, 5.0, 7.5 and 10%). Guava ( Psidium guajava ) contains dietary fiber and total phenolics content, 12.72% and 927.66 mg gallic acid equivalent (GAE)/100 g, respectively. Results showed that, the addition of GPP significantly (p < 0.05) increased the crude fiber and total phenolic content of GF bread from 0.92 to 2.45% and 14.46 to 103.77 mg GAE/100 g respectively. The loaf volume increased up to a level of 492.00 cm 3 , hence decreased the hardness from 2.58 to 2.38 N. Furthermore, as the concentration of GPP increased from (0–10%) the L* value of GF bread decreased. The addition of GPP, non-significantly (p > 0.05) affected the protein content and calorific value of GF bread. Sensorial analysis showed that, GF bread supplemented with 5% of GPP presented overall acceptability better when compared with control.

Efficient utilization of solar energy for solar steam generation is an effective way to tackle the shortage of fresh water resources. However, the utilization of solar steam evaporators often suffers from a series of problems, such as high cost, complex processes, and low conversion rate, which seriously hinders the development of solar steam devices. Here, a polypyrrole/watermelon pulp (WPPY) evaporator, which is based on soaking freeze-dried lumpy watermelon pulp (WP) in pyrrole solution, initiating polymerization in the ice bath, followed by heat-treatment to achieve an efficient solar steam generation (SSG) device, is designed and produced. The WPPY with a pyrrole to WP mass ratio of 1:2 (WPPY-3) exhibits a developed porous structure, superior hydrophilicity, relatively small thermal conductivity (0.0375 W m −1 K −1 , a simple one-step fabrication process, and superior light absorption (94.7%). Its evaporation rate reaches 1.64 kg m −2 h −1 without additional insulation, while the light-to-heat conversion efficiency reaches 96.1% under one solar irradiation (1 kW m −2 ) at the same time. Additionally, it also shows good durability. This environmentally friendly and stable photothermal conversion composite material that shows good cycle stability has great potential for applications in seawater desalination via SSG.

Furanocoumarins in citrus fruit can cause adverse drug interactions, however, there are few reports on furanocoumarins and drug interactions in common edible citrus cultivars except grapefruit. A UPLC-based method for ten furanocoumarins in citrus fruit was established and impacts on cytochrome P450 activity were investigated. Furanocoumarins were more abundant (2–43 times) in the peel than in the pulp. The pulp of Xiyou, Hongyou and Navel orange exhibited P450 inhibition with IC50 values of 0.63, 0.67 and 1.02 mg/mL, respectively. The peel of most varieties except Huyou and Satsuma exhibited P450 inhibition. Xiyou, Huangjinyou, Baiyou, Hongyou, Ponkan and Navel orange had IC50 values of 0.33, 0.38, 0.76, 0.35, 0.43 and 0.37 mg/mL, respectively. These findings indicate that the consumption of the pulp of popular Chinese varieties of citrus fruit except for Xiyou, Hongyou and Navel orange has a low risk of drug interactions, and use of citrus products including peel may carry a significant risk of adverse drug interactions.

The aroma chemical composition of commonly planted kiwifruit cultivars in China was analyzed. The combination of 2-octanone with 3-octanone was the most suitable dual internal standard for quantitative analysis in GC-MS. A total of 172 aroma components in 23 kiwifruit cultivars were detected, and ethyl butanoate, (E)-2-hexen-1-ol, and (E)-2-hexenal could be considered the core aroma components in kiwifruit, but still need further confirmation using Sensomics. E-nose could effectively distinguish different cultivars of kiwifruit. Clustering based on GC-MS and E-nose results tends to be consistent and demonstrate a certain degree of similarity. Kiwifruit cultivars with different flesh colors cannot be effectively distinguished by their aroma chemical compositions. Different species of kiwifruit can be distinguished to some extent by their aroma chemical compositions, but the effect was not satisfactory. These results could prove valuable in the breeding, planting, and marketing of kiwifruits.Keywords:kiwifruit;chemical compositions;E-nose;GC-MS;flesh color;species

SO 2 fumigation treatment (commonly known as sulfur treatment, ST) is a key method in the postharvest preservation of imported and exported fresh longan fruits, effectively reducing pericarp browning and enhancing color. Nonetheless, distinctive aromas, often referred to as “sulfur flavor”, may develop in the aril during the extended preservation period. This study employed “Caopu” longan as the test material and patented SO 2 -releasing paper (ZL201610227848.7) as a treatment to perform a 35-day low-temperature (5 °C) storage of the fruit. The changes in glucosinolates (GSLs) and associated metabolites in the aril of treated fruit (ST) were examined utilizing ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) detection and widely targeted metabolomics technology. The findings indicated that following 35 days of storage, nearly all control (CK) fruit pericarp turned to brown, resulting in an edible fruit rate of 75.41% and a commercial fruit rate of 0%. In contrast, the treated (ST) fruit demonstrated an edible fruit rate and a commercial rate of 99.44%, while the pericarp color changed from dark yellow-brown to light earthy yellow. The sulfur-containing metabolites identified in longan fruit aril predominantly consist of amino acids and their derivatives (60.44%), followed by alkaloids (15.38%), nucleotides and their derivatives (1.10%), and other types (23.08%), which include GSLs. SO 2 treatment significantly reduced the content of oxidized glutathione in fruit aril but increased the content of GSLs and related amino acids and their derivatives. Via screening, 19 differential sulfur-containing metabolites were obtained between ST and CK, including 11 GSLs. The identified differential metabolites of GSLs were all increased, primarily comprising aliphatic GSLs, such as 1-hydroxymethyl glucosinolate, 2-Propenyl glucosinolate (Sinigrin), and 4-Methylsulfinylbutyl glucosinolate (Glucoraphanin). Pathway analysis showed that these differential metabolites were mainly involved in coenzyme factor synthesis, cysteine and methionine metabolism, and amino acid synthesis, among other pathways. To the best of our knowledge, this is the first study to reveal the causes of the special flavor of longan aril after SO 2 treatment, which is a great concern for longan consumers. Moreover, this study provides a scientific basis for exploring the reasons and mechanisms for the development of the sulfur flavor in the SO 2 -treated fruits during postharvest storage.

This study aimed to develop an eco-friendly and high-efficiency method for extracting carotenoids from canistel pulps (CPs) by ultrasound-assisted natural fatty acids-based deep eutectic solvents (DESs). The DES consisting of menthol and capric acid (Men-CaA, 2:1) resulted in the highest total carotenoids content (TCC) of 614 ± 3 μg β -carotene equivalent ( β -CE)/g DW. The conditions of ultrasound-assisted Men-CaA extraction were then further optimized by using response surface methodology (RSM). The maximum extraction yield of TCC (831.0 ± 0.3 μg β -CE/g DW) was achieved under the conditions of ultrasonic power of 320 W, liquid to solid ratio (L/S) of 6:1, temperature of 40℃, and ultrasound time of 18 min. In addition, ultrasound significantly intensified the extraction of carotenoids from CPs. The carotenoids compositions in CPs were also identified using UPLC-QTRAP-MS/MS for the first time. Men-CaA extract exhibited much higher content of lycopene (499 ± 1 μg/g DW) compared to the acetone and corn oil extracts. Molecular dynamic simulation confirmed that more non-covalent bonds were found between Men-CaA and lycopene . Overall, an ultrasound-assisted eco-friendly fatty acids-based eutectic solvent method was successfully developed for highly efficient extraction of carotenoids from agricultural by-products.

Longan pulp polysaccharide is a bioactive component with prebiotic activity and intestinal barrier protection. This study aimed to evaluate the influence of digestion and fermentation on the bioavailability and intestinal barrier protection of polysaccharide LPIIa from longan pulp. The molecular weight of LPIIa didn’t change significantly after gastrointestinal digestion in vitro . After fecal fermentation, 56.02% of LPIIa was consumed by gut microbiota. The short-chain fatty acid level in LPIIa group was 51.63% higher than that in blank group. LPIIa intake also increased short-chain fatty acid production and G-protein-coupled receptor 41 expression in the colon of mice. Moreover, LPIIa improved the relative richness of Lactobacillus , Pediococcus , and Bifidobacterium in colon content . Compared to LPIIa, fecal fermented LPIIa better protected intestinal epithelial barrier by increasing Zonula occludens-1 expression. These results provided an important basis for the design of functional food based on longan polysaccharides to prevent intestinal barrier damage related diseases.
