Abstract The major objective of this study is to report physico-chemical properties of sunflower oil samples collected from different stages of the technological process for sunflower oil refining for food industry. The samples of oil were crude oil, washed oil, bleached oil and deodorized oil. The physico-chemical properties of sunflower oil experimentally determined were density, saponification value (SV), iodine value (IV), and acid value (AV). It was found that the density of sunflower oil remains approximately constant over the different stages of the manufacturing flow of cooking oil, except the crude oil. The acid value significantly decreases from crude oil (2.588) to deodorized oil (0.366). The iodine value and saponification value of the different samples of the sunflower oil corresponding to different stages of oil processing varies slightly. The capacity of different models to accurately correlate and/or predict the density of vegetable oil was tested. The density of sunflower oil can be accurately estimated from its SV and IV or with an empirical equation, when density data are available.

Due to the high demand for vegetable oil by soap industries, the quest for alternative raw material is on the increase. In this study, vegetable oil was extracted from the underutilise seeds of Lagenaria siceraria using n-hexane; The Physico-chemical properties of the oil were analysed: iodine value 65 Ig/100 g, acid value 2.50 mg/KOH/g, saponification value 256 mgKOH/g, pH 6.20, specific gravity 0.902, the refractive index of 1.47 and oil yield 52%. The properties of the oil were compared with oil extracted from other sources. The properties of the oil suggest it can use for both commercial and industrial purposes. The extracted oil was then used to prepared soap and its properties were compared with the properties of soaps prepared from other oils. The physicochemical parameters of the prepared soaps which include foam height, hardness, pH and cleansing power were evaluated. The soap made from Lagenaria siceraria seeds oil has foam height of 2.0 cm lower than palm kernel oil (2.1 cm) and higher than soya beans (0.55 cm). Soap made from Lagenaria siceraria seed oil has an appreciable degree of hardness and good cleansing power compared to soaps prepared from other oils. The pH of all the soaps prepared is within the standard of the regulating agency in Nigeria. From the result obtained, it shows the underutilised Lagenaria siceraria seed oil can use as an alternative raw material in the commercial production of soap.

Castor oil having low content of unsaponifiable matters was chosen for the development of new jute batching emulsion processes. The suitability of the castor oil was also assessed in terms of its favourable colour, odour, specific gravity, acid value, iodine value, saponification value, viscosity, pour points and flash points in comparison to those of conventional JBO. Different recipes for the production of emulsions were standardized in the industrial scale and their suitability were assessed according to their stability, specific gravity, temperature, viscosity and pour points. The recipes were used to spin jute fibre in the jute mill machines. The yarn products were studied to evaluate their work performances based on their physico-chemical properties: moisture regain, t.p.i., W.I., count, strength, tenacity, extension, textile modulus, toughness, QR, oil content and unsaponifiable matters. The yarn products were particularly evaluated in terms of their unsaponifiable matters based on the IJSG criterion. The yarns of processes show quality ratio 93.93 to 104.20 and unsaponifiable matters ranging from 126.05 to 414.92 mg/kg yarn and easily pass the IJSG criterion. The processes therefore appear to be of commercial importance. Key words: Food items, IJSG criterion, JBO, Jute sacks, Unsaponifiables, Vegetable oils.

This research seeks to determine the effect of storage periods and packaging materials on the proximate and chemical properties of frozen blue whiting (Micromesistius poutassou) at different exposure time – 0 hour, 2 hours and 4 hours, on arrival at the laboratory. Frozen M. poutassou were bought and stored in a commercial cold room for 12 weeks at -10oC and packed in different packaging materials (Ziploc bag, foil paper and carton) with un-wrapped samples for analysis which lasted 90 days and was conducted every 14 days to measure the moisture, protein, fat, ash, fibre and nitrogen free extract (NFA) content of the fish sample as well as iodine value, peroxide value, saponification value, acid value, free fatty acid and hydroxyl value of fish oil. The result clearly reveals that during storage, the different packaging materials showed significantly (p<0.05) decreasing trend in protein, lipid, ash, fibre and NFA content with increasing storage period and time of analysis except for the moisture content that showed opposite trend. For the chemical properties, the saponification value, peroxide value, free fatty acid, acid value and hydroxyl value showed significantly (p<0.05) increasing trend in the different packaging materials with increasing storage period and time of analysis. While the iodine value decreased with increasing period of storage and time of analysis; the iodine, saponification, peroxide and hydroxyl values were not within the acceptable limits.

The physiocochemical properties of Jatropha curcas kernel oils were characterized as potential biodiesel, including oil yield per plant, seed oil content, kernel oil content, acid value, iodine value, saponification value and cetane number. Twenty-five accessions of Jatropha curcas were used for oil content measurement sranging from 21.14 to 40.66 %with a mean value of 32.85% and Kernels oil 48.59 to 60.45 % with a mean value of 56.28 %. The seed index ranged significantly from a seed weight of 45.45 to 64.45 g. Oil yields per plant ranged from 0.44 to 2.85 kg with a mean value of 1.70 kg per plant, respectively. To understand the properties of acid value, iodine value, saponification and cetane number, experimental physio-chemical studies were performed. Since these properties are critical for determining the current oil condition. The current study confirms that accession seeds performed higher than international saponification value, iodine value and cetane number standards may be an important source for meeting potential energy requirements.
