Opis:
The article discusses the continuous process of preparing the youth for marriage and family life, occurring in three stages: remote, proximate and immediate. Remote preparation commences already in childhood and hinges on gaining suitable knowledge and desirable attitudes towards marriage and family life. Proximate preparation covers high-school students and constitutes a kind of pre-marital catechesis, realized both in the school and parish. Immediate preparation is addressed chiefly to future married couples who are only several months from concluding marriage and establishing a family. Thorough preparation at the three stages influences not only the condition of the modern family but also future of the Church and all human beings.

Opis:
This article presents the concept of marriage love in terms of education. Marriage love is defined as „attitude” including marriage of inclusivity and uniqueness of each of the spouses. Marriage love begins at home and family since the first moments of child's life. Then, in fact, parents satisfy needs of love and belonging, their child and develop his or her ability to love. The child observes their parents and learns from them what is love and how it should look in the future. The element of education for marriage love is the preparation which covers the period of engagement, religious instruction, premarital education, counseling meetings in family life and confession. It is time that the spouses should come to know themselves, their future plans, learn how to communicate and cope with conflicts. Parents' love is the kind of foundation for the later child's love for his or her spouse and gives a shape its expectations for the other person.

Opis:
Gari fortified with Bambara Groundnut Flour (BGF) was assessed for its proximate composition, functional properties, sensory evaluation and Rheological properties. Four samples; 100% gari (coded SLY), 90 % gari with 10 % BGF (coded ATS), 85 % gari with 15 % BGF (coded FEA), and 80 % gari with 20 % BGF (coded ROT) were examined for the parameters listed above. The proximate analysis showed that the protein content ranges between 0.98-4.68 %, fat content 1.10-2.60 %, ash content 1.82-2.90 %, crude fibre 2.30-2.42 %. This showed an increase on addition of BGF while the carbohydrate content ranges between 78.20-83.5 %, moisture 11.60-12.6% and acidity 0.40-0.60, all showed a decrease in value on adding BGF. Rheological value showed that the peak viscosity ranges between 106.17-177.17, trough viscosity 98.33-161.00, breakdown 7.83-16.71, final viscosity 150.50-251.67, set back 52.17-90.67 and pasting time between 6.87-6.93. All these varied inversely with the quantity of BGF added. Pasting temperature showed slight variation which was not dependent on the amount of BGF added. It ranges from 79.2-80.02 °C. Sensory evaluation showed that there were significant differences in the samples examined.

The nutritional effects of marine food have increased far and wide due to the beneficial effects of consuming marine food, fats and oils. In general, the proximate composition is well known as a proportion composition of basic elements such as protein, lipids, carbohydrate, minerals and water. The puffer fish Lagocephalus lunaris and Lagocephalus inermis were collected at Mudasal odai fish landing centre and the skin and visceral organs like gonads and intestines were removed the edible portion only took for the analysis. Species of the fish sample was oven-dried in an electric oven at between 70 – 80 °C until the samples had constant weight. The protein, carbohydrate, fat, ash and moisture content of green -rough-back puffer fish and smooth-backed blow fish were investigated. L. lunaris and L. inermis were has 9.22 %, 8.92 %, 1.96 %, 1.87 %, 11.25 %, 11.98 %, 80.32 %, 86.05 %, 0.96 %, 1.27 % respectively. Totally seven saturated fatty acids; ten Mono unsaturated fatty acids and two poly unsaturated fatty acids were found as the major components on the investigated puffer fish. Polyunsaturated fatty acid like n-3 has 31.17 %, 31.19 and n-6 7.26 %, 7.29 % of PUSFA found as the dominant composition on puffer fish. This study revealed that these species are having high saturated fatty acid and protein content and able to compete with more commercially utilize species in terms of nutritional value, and they can definitely also compete when it comes to taste. It can act as a good source of nutritional and economic value when it is carefully handled and properly cooked.

Proximate, ultimate and chemical composition of four varieties of dates, namely Digila, Krikri, Sukur and Trigal were determined in the pulp. In addition, the seed kernel of dika nut (Irvingia gabonensis) was assessed on a dry weight basis. The proximate analysis included moisture, volatile matter, Fixed Carbon and ash, respectively, with the pulp of Digila having the highest fixed carbon of 72.73%, while the krikri date pulp contained the highest moisture of 79.22%, Sukur pulp has the highest volatile matter of 59.20%, and Trigal seed contained 88.05% moisture - establishing that its kernel holds the highest moisture content among the four cultivars. Ultimate Analysis showed that Digila and Trigal pulp contained the same amount of total carbon (94.10%), the pulp of Krikri contained the highest amount of hydrogen (3.55%), while the pulp of Sukur has 1.44% Nitrogen, and the dika nut seed contained 9.82% Oxygen - making it the highest. Moreover, Sulpur, Digila, Sukur, Trigal and Krikri have available hydrogen, nitrogen, oxygen, sulphur, sodium, potassium, calcium, magnesium, iron, zinc and phosphorus for the body to absorb for physiological activities, but lacked chlorine, aluminum, and silicon at detectable levels. All these quality food properties make dates a good source of sweetening agent in the food processing industry.

Opis:
Phytochemicals, proximate, minerals and anti-nutrient compositions of young cocoyam (Colocasia esculenta) leaves were determined using standard methods. Qualitative and quantitative analyses for phytochemicals confirmed the presence of bioactive constituents such as alkaloids, flavonoids and saponins in appreciable amounts, while terpenes, cardiac glycocides and tannins were only present in trace concentrations. Mineral analysis revealed that K recorded the highest content - with 214.00 ± 2.11 mg/100g, followed by Ca - 157.10 ± 1.47 mg/100g, Mg - 63.00 ± 0.58 mg/100g, P - 32.00 ± 0.61 mg/100g, while Fe had the lowest value - 0.10 ± 0.14 mg/100g. Proximate composition analysis of C. esculenta leaves indicated that CHO, protein and crude fibre were present in high quantities (35.22, 17.10 and 16.41 % respectively), while fat was at the lowest content (8.82%). Anti-nutritional factor analysis of young leaves of C. esculenta indicated that phytates was present in huge quantity - 11.03 ± 0.12mg/g, followed by oxalates - 7.62 ± 0.14 mg/g, while tannins recorded the lowest anti-nutritional contents - 0.12 ± 0.06 mg/g. This study has also revealed that the young leaves of C. esculenta contain appreciable levels of bioactive components (phytochemicals such as as alkaloids, flavonoids and saponins; minerals K, Ca, Mg, P and Fe) and appreciable amounts of CHO, protein and crude fibre. The results of anti-nutrients analysis showed high contents of phytate and oxalate. The last is probably responsible for the itching effect and also interferes with the utilization of essential nutrients. Thus, young leaves of C. esculenta provide appreciable quantities of nutrients and thus can rival other conventional vegetables normally consumed in Nigeria.

Determination of the proximate, nutritionally valuable mineral in five samples of food seasonings label as, A, B, C, D, & E food condiments readily consumed in Nigeria were obtained from Gwagwalada Central Market Abuja. Investigating the concentrations of some mineral elements such as, iron (Fe), zinc (Zn), and two heavy metals, cadmium (Cd) and lead (Pb) were carried out using AA320N Atomic Absorption Spectrophotometer (AAS) after acid digestion with 2:1 HNO3/HClO4. The result shows that all samples contained high levels of protein (13.63% ±0.53%) with mean value moisture, ash, fat, fiber, and carbohydrate for all samples levels being (3.94%±0.64%), (57.51% ±4.27%), (5.11% ±0.20%), (0.02% ±0.00%) and (18.41% ±0.41%) respectively. Sample D has high Fe concentration with (0.04 ±0.01 μg/g) and Sample B & C has low Fe concentration with (0.01 ±0.00 μg/g). Sample D & E has high Zn concentration with (0.03 ±0.01 μg/g) and sample A, B & C has low Zn concentration with (0.02 ±0.01 μg/g). In cadmium, sample A has the high concentration (0.03±0.01μg/g), sample B & D has the low Cd concentration (0.02 ±0.00 μg/g). Sample D had the high Pb concentration (0.05 ±0.00 μg/g), sample C had the low Pb concentration (0.02±0.01 μg/g). In conclusion, Fe, Zn, Cd and Pb were both present in low concentrations in all the samples analyzed. The presence of Cd and Pb in the food seasonings even at low concentration could prove fatal through bioaccumulation. The low level of the toxic metals, Pb and Cd indicates that these products meet the safe limits specified by most food standards.

Opis:
Mackerel of Scomberomorus commerson (Lacepède, 1800) is a fish that has thick meat of a distinctive taste and is a favorite of Indonesian people. It is made into various types of processed seafood. The amount of edible flesh of the fish is 65%, meaning that the waste from the fish is 35%, including the head and bones. The purpose of this study was to determine the type and class of volatile compound components that can be drawn from mackerel head and fish bone, by making these into a broth. This study uses an experimental method by testing the composition of volatile flavor compounds and then undertaking proximate testing. The method of extracting volatile flavor compounds that was applied is Solid Phase Microextraction (SPME), while Gas Chromatography / Mass Spectrometry (GC / MS) was harnessed to identify the volatile flavor. Accordingly, 150 compounds were detected in the sample of mackerel head broth, as compared with 133 compounds in mackerel bone broth.
