Kefir is a food-based on pasteurized milk fermented using lactic acid bacteria, aceticacid bacteria, and yeast. The study aims to analyze proximate levels (carbohydrates, proteins,and fats) and identify the characteristics of sensory changes during storage. This true experimental study uses a complete randomized design with 1 factor. Thecomposition of corn milk kefir consists of 3 levels (K1=corn milk: skimmed milk 100:0;K2=corn milk: skimmed milk 75:25; K3=corn milk: skimmed milk 50:50).  Data analysisusing One Way Anova showed that carbohydrate content (10.31 + 1,426), fat (0.18 + 0.018),and protein (1.83 + 0.973) significantly different (p=0.0001). The 35 days of storage in the refrigerator (2-8C) results in a change in kefir colorbecoming more faded. The kefir texture before storage is different for each kefir compositionand becomes more viscous at the end of the storage period. The sour aroma of kefir willincrease during kefir storage. It can be concluded that protein and fat levels increase alongwith an increase in the amount of skimmed milk addition, while carbohydrate levels decreaseat the addition of the most skimmed milk (K3).Keywords: kefir, proximate, sensory characteristics, shelf-life, skimmed milko

RESUMO - Com a finalidade de avaliar os efeitos imediatos e latentes da secagem com altas temperaturas, usando lenha como combustível, nas qualidades física, química e tecnológica de grãos de milho, foram utilizadas três temperaturas do ar de secagem: 60 ºC, 60/80 ºC e 80 ºC. As análises realizadas foram de: peso de 1.000 grãos, massa específica, umidade, análises químicas de proteína bruta, acidez titulável, material mineral e análise de defeitos nos grãos. O estudo foi conduzido conforme o delineamento inteiramente casualizado, em esquema fatorial, sendo os dados submetidos à análise de variância e, posteriormente, ao teste de Tukey e à análise de regressão. Com base nos resultados obtidos, concluiu-se que: 1. A massa específica dos grãos de milho apresentou redução de forma direta com os incrementos da temperatura de secagem e do tempo de armazenagem; 2. As reduções do peso de 1.000 grãos e do incremento de avariados ocorreram em função do tempo de armazenamento; 3. O percentual de grãos carunchados foi menor nas maiores temperaturas de secagem, porém com incremento ao longo do período de armazenagem, exceto para a secagem a 80 ºC; 4. Ao longo do tempo de armazenagem, foram observados incrementos na acidez do óleo e na material mineral, com maiores valores, ao final da armazenagem, naqueles grãos submetidos a maior temperatura do ar de secagem.Palavras-chave: Zea mays; secagem com altas temperaturas; efeitos latente e imediato.QUALITY OF MAIZE GRAINS SUBMITTED TO FIREWOOD DRYING AND STORED UNDER NATURAL ENVIRONMENTABTRACT - In order to assess the immediate and latent effects of drying at high temperatures (using wood as fuel) on the physical, chemical and technological quality of maize grains, three temperatures were used for drying: 60°C, 60/80 º C and 80ºC.: Grain weight, density, moisture, chemical analysis of crude protein, acidity, mineral material, and defects in grains were evaluated. The study used a completely randomized design in a factorial scheme, and the data were submitted to analysis of variance. Tukey test and regression analysis were subsequently performed. The results showed that: 1. The specific mass of the corn grains decreased directly with increasing drying temperature and storage time; 2. Reduction in the thousand kernel weight and increase in damaged grains occurred with increasing storage time; 3. The percentage of rotten grains was lower in higher drying temperatures, but was higher as the storage period increased, except for drying at 80°C; 4. During the storage period, increases in acidity of the oil and mineral material were observed, with higher values at the end of storage period for those grains subjected to higher drying temperature.Keywords: Zea mays; drying at high temperatures; latent and immediate effect.

Maize (Zea mays L.) is the world’s leading edible oil and third largest important cereal. In addition to it is used as food for human consumption as well as food grain for livestock. High concentrations of NaCl in soils account for large decrease in the yield of a large variety of crops all over the globe. The objective of the present study was conducted to evaluate NaCl stress on growth and mineral nutrient composition of maize plants. Maize seeds were grown in plastic pots having fine sand. After 20 days of germination, the plants were subjected to seven different concentrations (Control, 25mM, 50mM, 75mM, 100mM, 125mM and 150mM) of NaCl. Plants were analyzed on 15th day after salt treatment. Factorial experiments in a completely randomized design (CRBD) with three replications were applied. The growth parameters and mineral contents Na, Ca, K and Cl were investigated from saline treated and non saline treated plants. Results indicated that the NaCl stress markedly reduced the shoot and root length fresh and dry masses. Moreover Na+, Cl- content increased with increase in NaCl stress, while Ca2+ and K+ were decreased significantly.

[email protected]   RESUMO: A cultura do milho (Zea mays L.) possui grande importância para a economia mundial e sementes com alto potencial fisiológico são premissas para um bom desempenho produtivo agrícola. Os sistemas de armazenamento objetivam manter a viabilidade das sementes, controlando fatores como umidade e temperatura, principais causas de deterioração. Logo, avaliar o vigor de sementes e seu potencial germinativo, visando como se estabelecerão em campo, é essencial para o controle da qualidade. O presente trabalho buscou avaliar o potencial germinativo e vigor de sementes de quatro híbridos de milho, armazenados em embalagens de papel multifoliado, a partir dos testes de germinação e frio. Foram também avaliados o teor de água, índice de velocidade de germinação, tempo médio de germinação e comprimento de plântulas. Utilizou-se o delineamento inteiramente casualizado, com 4 tratamentos e 4 repetições, os resultados foram submetidos ao teste de Tukey (p < 0,05). O híbrido X2 safra 18/18 com vencimento em junho de 2019, apresentou potencial próximo ao indicado pelo fabricante, os demais não alcançaram o percentual mínimo de germinação apontado pelo fabricante. O armazenamento inadequado das embalagens após abertas podem ter reduzido sua eficácia na conservação das sementes, resultando na redução do potencial fisiológico das sementes de milho.   Palavras-chave: embalagens, germinação, vigor.   PHYSICAL AND PHYSIOLOGICAL QUALITY OF CORN SEEDS (Zea mays L.) AFTER STORAGE   ABSTRACT: The culture of corn (Zea mays L.) has a great importance for worldwide economy and seed with high physiological potential is a premise for good agricultural performance. The storage systems aim to maintain the viability of the seeds, controlling factors such as humidity and temperature, the main causes of deterioration. Therefore, evaluate the vigor of seeds and their germinative potential, aiming at how they will be established in the field is essential for quality control. The present work sought to evaluate the germinative potential and vigor of seeds of four corn hybrids stored in multifoliate paper, based on germination and cold tests. Also applied were: water content, germination speed index, average germination time and seedling length. The randomized design was used, with 4 treatments and 4 repetitions, the results were submitted to Tukey test (p < 0,05). The hybrid X2 crop 18/18, maturing in June 2019, show the next potential indicated by the manufacturer, the rest not achieved or the minimum percentage of germination indicated by the manufacturer. Reduced storage of packages, after opening, can reduce physiological potential of corn seeds.   Keywords: packaging, germination, vigor.

This research was aimed at understanding the corn plant using plastic covers. The above mentioned plant was grown in plastic covers that have colours (transparent, red, green, and blue) and without plastic covers. This research was carried out in the Faculty of Agriculture, IPB from the month of May to June 2008. It was implemented using the Completely Randomized Design with three repetitions. The results of the research show that light intensity was higher in the plant that was not enclosed in the plastic covers. Generally, the research shows that the corn plant that was in the plastic covers is better than that one without plastic covers. The use of a plastic cover helps increases the height of the corn plant and the leaves. Chlorophyll a and Chlorophyll b are higher in the corn plant that was not in the plastic covers. The results of the research also indicate that transparent and red plastic covers have better responses compared to plastic covers with blue and green colors.

Microbiological Properties

Jackfruit seeds are rich in carbohydrates and protein. It can be processed into flour as a nutritious product which can be stored for future use. However, jackfruit seed flour has limited cooking applications, thus, the need to improve its functionality through natural fermentation process. The study was conducted to determine the effects of lactic acid and fermentation time on the physicochemical, functional and microbiological properties of the fermented jackfruit seed flour, compared to its unfermented counterpart. A 3x3 full factorial design following Completely Randomized Design (CRD) with different levels of lactic acid (0, 1.5, 3%) and fermentation time (16, 24, 32 hours) and with a control treatment was used. Data for all experimental combinations were analyzed using One-way ANOVA where means were compared using Tukey's HSD. Analysis of variance results revealed that the physico-chemical and functional properties of control treatment is significantly different from the fermented jackfruit flour in terms of pH, moisture and carbohydrates. Moreover, fermentation and lactic acid contributed to increase in quality values of the jackfruit flour except for %energy, %carbohydrates and bulk density. The faster drop in pH brought about by lactic acid increased the count of aerobic bacterial, lactic acid bacteria, yeasts and molds.

A screen house study was conducted to evaluate the effect of gemstone mining on the growth behaviour of maize Zea mays L. A completely randomized design involving two samples of soil (FUTA (control) and Ijero (mined soil)), two varieties of the maize (TMZ234 and Sammarz 39) was used. The seeds were sown into experimental pots containing the soils and the whole set up was left for eight weeks. Growth parameters (plant height, leaf area and stem girth were taken at a weekly basis up till the eight week. Eight heavy metal (Cd, Cu, Cr, Fe, Ar, Zn, Pb and Ni) concentration in the soils, roots and shoots of the plants was determined at the end of the experiment using atomic absorption spectrophotometer. Baseline data indicates that the mined soil is acidic (pH 4.12), with low organic carbon (0.92), low organic matter (1.59) and low total nitrogen (0.76). Results obtained from this study show that all growth parameters were negatively affected by the mined soil. Plant height was significantly higher in the control varieties (82.28 and 40.46, respectively) when compared with the mined soil varieties (30.5 and 29, respectively) at 8 weeks after planting (WAP). Leaf area also followed the same pattern with varieties grown on control soil having significantly higher leaf area (48.22 and 25.22, respectively) than varieties grown on mined soil (19.08 and 19, respectively). Stem girth of variety TMZ234 in control soil was also significantly higher than the rest (2.24 as against 1.68, 1.5 and 1.74). Heavy metals concentration in the soil, shoot and root of the plants grown in mined soils were all higher than in those grown on control soils. In the soil, Cr, Ni and Pb were 0.24, 0.15, 0.10 and 0.20, 0.13, 0.10, respectively, in both varieties grown on mined soils as against 0.03, 0.01, 0.00 and 0.03, 0.08, 0.00 for Cr, Ni and Pb, respectively, for both varieties grown on control soils. Bioaccumulation and translocation factors for the metals were less than 1 in all the soils except for Ni which had BCF of 2.80 and 6.90 for both varieties grown in the control soils. The results from this study has shown the negative effect of gemstone mining activities on the growth of two varieties of Zea mays.
