“…Overall, the total extractive content (1.82% based on OD APS) was higher than reported by Yeganeh et al (0.41% [23]) but lower than other results reported earlier: in accordance with Wei et al [22], APS contain 5.2% extractives while oil and polyphenolic compounds are present in the amount of 1.6%-2.2% and 0.74%-0.9% respectively in accordance with the results of Cañellas et al [12]. The low solubility of APS in cold and hot water indicates a minute amount of water-soluble carbohydrates, such as free sugars, glycosides, and starch.…”

“…Relatively low ash content (0.55%) determined in this study was lower than found by Cañellas et al (1.67% [12]) but between the values reported by other research groups (0.17% [22]; 0.2% [10,11]; 0.3% [23]; 0.78% [9]; 1.0% [24]). The ash content of apricot pit shells appears to be less, on average, than recorded for other fruit stones, seeds, and nut shells (nut shells: 1.2%-3.8%; almond shells: 1.54%-2.3%; cherry stones: 0.9%; grape seeds: 2.5% [10,11]), demonstrating benefits of using apricot pit shells for combustion, pyrolysis, or carbonization.…”

“…The lignin content reported for APS earlier varies considerably and ranges from 23.4% to 51.43% [10,12,22,23]. It should be noted, however, that on average, nut shells and fruit stones tend to contain more lignin than wood (walnut shell: 33.3%-52.3%; almond shell: 20.4%-27%; hazelnut shell: 27.2%-43.01%; apricot stone: 23.4%-51.4%; wood: 20%-33%; with compression wood 37%-40%; [10,12,[25][26][27]). …”

“…APS may be used for the production of activated carbon or converted to a gas mixture composed of mostly carbon monoxide, carbon dioxide, and methane [8][9][10][11][12], while kernels, which contain dietary proteins, oils, and fiber, exhibit antioxidant and antimicrobial activities and may be used in the production of oils, benzaldehyde, and cosmetics [1,13]. Valorization of APS is also consistent with efforts to develop materials, fuels, and processes that utilize lignocellulosic materials in place of fossil fuels [14].…”

Chemical Composition of Apricot Pit Shells and Effect of Hot-Water Extraction

Abstract:Agricultural residues, such as corn stover, wheat straw, and nut shells show promise as feedstocks for lignocellulosic biorefinery due to their relatively high polysaccharide content and low or no nutritional value for human consumption. Apricot pit shells (APS) were studied in this work to assess their potential for use in a biorefinery. Hot water extraction (HWE; 160 °C, 2 h), proposed to remove easily accessible hemicelluloses, was performed to evaluate the susceptibility of APS to this mild pretreatment process. The chemical composition of APS before and after HWE (EAPS) was analyzed by standard methods and 1 H-NMR. A low yield of the remaining HW-extracted APS (~59%) indicated that APS are highly susceptible to this pretreatment method. activity (AOA) of APS extracts was also undertaken. AOA of organic APS extracts were shown to be more than 20 times higher than that of a synthetic antioxidizing agent.

This research was conducted to prepare apricot diet jam from the pulp of fresh mature apricots by using artificial sweeteners i.e. aspartame and saccharine. Apricots were washed with clean water to remove dust particles. After sorting and pitting, apricots were cut into two halves with the help of stainless steel knives and dipped in 0.1% citric acid solution to avoid browning. The pulp of apricots was extracted by using plumper. Apricot pulp was heated to get the desired consistency. Low heating was continued and brix were noted after every 20 minutes. At the end two different artificial sweeteners were used for the preparation of jam. Pectin with small amount of non nutritive sweeteners were dissolved separately and added to the mixture. Preservatives and color was added at the end of cooking. At 21 0 brix the product was poured into the jam bottles, already washed, cleaned, sterilized and without moisture. Bottles were caped and stored at ambient room temperature. After three days the samples were studied for their chemical characteristics. The parameter (i.e.) moisture, acidity, total soluble solids, ascorbic acid, pH, reducing sugar and non reducing sugar were determined in apricot diet jam. Physicochemically the mean values of the results were 3.69 pH, 0.66% total acidity, 6.54% vit. C (mg/100g), 77.01% moisture, 21.3% TSS, 4.13% reducing sugars, and 9.2% non reducing sugars.

Apricot kernel is one of the most abundant types of agro-waste in the eastern Anatolia regions of Turkey. In this study, apricot kernel shells (AKShs) were chemically modified using levulinic acid (LA) for the first time, and their potential for developing biobased composites was evaluated. Phenol novolac epoxy resin was used as matrix owing to its high thermal and superior adhesion properties. Shell treatments to improve interfacial bonding were carried out using alkali, acetic acid, and LA. These treatments were aimed at improving the mechanical properties, wettability, and bonding of the composites.Moreover, these treatments could prevent the deterioration of the fiber/matrix interface (hydrophilic and hydrophobic effect) and mitigate damage to the fiber during production, which is one of the main reasons for the reduced strength of the composites. The thermal characteristics, crystallinity index, chemical composition, and surface morphology of the untreated and chemically modified AKShs and composites were studied by thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy, respectively. In addition, the composites were analyzed in detail using mechanical tests and contact angle measurements. The chemical treatment using LA resulted in composites with superior mechanical behavior.
