Aim: Modern researches described incorporating gingerbread plum (Neocarya macrophylla) kernel oils into food, cosmetics and pharmaceutical products by exploiting its physicochemical properties. Study Design: Experimental and instrumental study was done to determine the general and the saturated fatty acids present in the seed oil and its suitability for industrial applications. This study examined the fatty acids by qualitative determination from hexane extracts of Neocarya macrophylla seed using GC-MS. Materials and Methods: Indigenous Neocarya macrophylla   seeds obtained from Gingerbread plum tree were collected in the Month of August from Birnin Kebbi, Kebbi State, Nigeria. soxhlet extraction method was used for the oil extraction. The GC-MS analysis was by coupling system of Shimadzu QP2010 series gas chromatography with Shimadzu QP2010 plus mass spectroscopy detector (GCMS).  For the FT-IR analysis, software of OMNIC operating system (Version 7.0 Thermo Nicolet) was connected to Fourier Transform Infrared Spectrometer Nicolet 8400S equipped with a detector of deuterated triglycine sulphate (DTGS). Conclusion: These results showed the potential of this oil in cosmetic industry.

Seed Inoculation

Seed inoculation of forage crops by arbuscular mycorrhizal fungi (AMF) generally results in higher profitability, but also modifies the chemical composition of silage in terms of increased biomass, protein, and dry matter. Raw milk aroma is affected by the type of feed. This work investigated the influence of ensiled forage obtained by seed inoculation with AMF on the volatile fractions and fatty acid composition of milk. Two experiments were carried out: in the first, buffaloes were fed maize silage, and in the second, cows were fed sorghum silage. The volatile fractions of milk were quantified by headspace solid-phase micro-extraction (HS-SPME), combined with gas chromatography–mass spectrometry (GC-MS), and fatty acids by gas chromatography (GC). The ensiled forage obtained with AMF increased saturated fatty acids (SFAs), and decreased monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) in both experiments. The volatile fraction in milk samples obtained from bovines fed mycorrhizal ensiled forage showed an increase of free fatty acids and ketones, responsible for cheesy and fruity odors. Aldehydes, responsible for green and grassy notes, increased only in the milk from buffaloes fed ensiled maize. Our results suggest that inoculation of maize and sorghum seed with AMF, combined with a low rate of fertilizers, leads to ensiled forage that could slightly affect the FA profile and odor quality of milk.

Synthetic Surfactant

Surfactants are essential in the pulp recovery process for the removal of ink on paper to be recycled. In order to create a “green” surfactant, seed oil was extracted from Morinda citrifolia L. by Soxhlet extraction for 4–8 h and its composition evaluated by gas chromatography-mass spectrometry (GC-MS). The total ion chromatogram (TIC) of fatty acids of Morinda citrifolia L. (FAMC) indicated that extraction yields the largest amount of unsaturated fatty acids (UFA), specifically C19H34O2 and C21H38O2, at 6 h. All FAMC fractions were evaluated for their suitability as a surfactant for deinking flotation. FAMC isolated after 6 h of extraction yields fatty acids that are the most suitable surfactants, as the fraction consists of mostly unsaturated fatty acids that show good interactions with the structure of common ink molecules. Our results show that the performance of the FAMC taken after 6 h of extraction approaches that of a synthetic surfactant (SS). The appropriate viscous force for deinking flotation was found to be 1.5–2.0 × 10−4 mg/mm s2 when the synthetic surfactant is used compared to 1.0–1.5 × 10−4 mg/mm s2 for FAMC. The higher intermolecular bonding strength in the synthetic surfactant-ink particle system requires higher viscous force.

Sugarcane peel is an agrowaste product and contains considerable amount of wax. This has a good technoeconomic potential. In view of this, the present study aims at extraction and characterization of wax from sugarcane peel. The yield of crude wax was 0.95% on dry weight basis. During Fourier transform-infrared spectroscopy (FT-IR) prominent peaks obtained at 2921.73 and 2851.64 (–CH), 1463.44 (–CH2), 1376.96 (–CH3), 1108.4 and 1170.16 (–C–O) 3395.60 (–OH), 1710.25 (–CHO), and 1736.63 (–COOH) indicate presence of alkanes, ketones, alcohols, aldehydes, and carboxylic acids, respectively. Alcohol and hydrocarbon fractions were also found by thin layer chromatography (TLC). Melting point of crude wax was observed to be 62.1°C. Molecular weight of wax was estimated to be 1706 Dalton. Composition of crude wax found using gas chromatography-mass spectroscopy (GC-MS) was alkanes (28.83%), ester (66.26%), fatty acids (4.58%), aldehyde (0.11%), and alcohol (0.22%).

The present study was aimed at analyzing the fatty acid composition, tocopherols, and physico-chemical characterization of wood apple (Limonia acidissima L.) seed oil and the nutritional profile of seed cake. The fatty acids in seed oil were analyzed by gas chromatography–mass spectrometry (GC-MS), and the total seed oil was 32.02 ± 0.08%, comprising oleic (21.56 ± 0.57%), alpha-linolenic (16.28 ± 0.29%), and linoleic acid (10.02 ± 0.43%), whereas saturated fatty acid content was 33.38 ± 0.60% including palmitic (17.68 ± 0.65%) and stearic acid (14.15 ± 0.27%). A greater amount of unsaturated fatty acids (52.37%) were noticed compared to saturated fatty acids (33.38%); hence the seed is highly suitable for nutritional and industrial applications. Gamma-tocopherol was present in a higher quantity (39.27 ± 0.07 mg/100 g) as compared to alpha (12.64 ± 0.01 mg/100 g) and delta (3.77 ± 0.00 mg/100 g) tocopherols, which are considered as natural antioxidants. The spectrophotometric technique was used for quantitative analysis of total phenolic content, and it revealed 135.42 ± 1.47 mg gallic acid equivalent /100 g DW in seed cake. All the results of the studied seed oil and cake showed a good source of natural functional ingredients for several health benefits.

Transesterification Method

The present study assessed the efficiency of two transesterification methods for the identification of fatty acids in the copepodTisbe biminiensisVolkmann-Rocco, 1973. In the first method, the samples were esterified by basic catalysis with KOH in methanol, and in the second method they were esterified by acid catalysis with BF3. Fatty acids were identified by comparison of retention times and co-injection with standard Mix C4-C24, using gas chromatography and gas chromatography-mass spectrometry. Twenty-nine fatty acids were detected in samples transesterified by basic catalysis or acid catalysis. The predominant fatty acids were C18 (19.18%), C16 (13.02%), and C12 (11.39%) for samples transesterified by acid catalysis; and C13 (25.24%), C21 (11.32%), and C18 (10.65%) for samples transesterified by basic catalysis. The results show that fatty acid analysis for copepods may be affected by the transesterification method. Sample transesterification by acid catalysis was efficient to identify monosaturated and polyunsaturated fatty acids, whereas transesterification by basic catalysis was efficient to identify saturated fatty acids. Essential fatty acids were present in the copepod, which suggests thatT.biminiensisis a useful food to be used in larviculture.

Development And Utilization

Crude and refined rubber seed oil (RSO) produced from Xishuangbanna, Yunnan Province was analyzed. After methylation and saponification, the contents of fatty acids and phytosterols were determined by gas chromatography and gas chromatography-mass spectrometry. Results showed that both the crude and refined RSOs contained high levels of unsaturated fatty acids and phytosterols. Four unsaturated fatty acid contents of 83.56% and 83.25% are found in both crude and refined RSOs, respectively. Six to seven types of phytosterols are found in both crude and refined RSOs. The contents of β-sitosterol are 12.13 and 11.22 mg/g in crude and refined RSO, respectively. This study provided fundamental instruction on the research, development, and utilization of RSO.
