The bio-deterioration of breadfruit in storage and its effects on the nutrient composition of the fruit was investigated at Ibadan, Southwestern Nigeria. Freshly dropped fruits were stored under laboratory conditions for a period of 9 days. Aspergillus niger, Rhizopus stolonifer, Botryodiplodia theobromae, Mycovellosiella fulva, Penicillium sp. and Aspergillus flavus, were found associated with deteriorating breadfruit in storage The freshly harvested breadfruit has 70.2% carbohydrate which reduced to 59.4% within 9 days of storage under room temperature. The amount of fat content, protein and the energy of the breadfruit also reduced in fruit samples stored for 9 days, while there was an increase in the moisture content, crude fibre, and ash content of the breadfruits in storage. The mineral contents also increased during the period of storage.
The effect of cold temperature storage on the quality attributes of pawpaw and guava leathers was evaluated. Pawpaw leather was significantly higher than guava leather in calorific content, water activity, pH and total mould count throughout the duration of storage. However Guava leather was higher in texture. Sensory scores in relation to period of storage showed that Guava leather gave better result in overall acceptability at zero, one and two months of storage at 8 ± 1 0 C. Guava leather also gave better sensory qualities in fruitiness, smell, chewiness, toughness, colour, and overall acceptability when varietal influence is considered. Guava leather is better accepted.
Freshly-blanched soybean seeds, mixed with grains of freshly-harvested green field maize were combined, in ratios of 5:1 (A), 4:1 (B), 3:1 (C); 2:1 (D), 1:0 (E) and 0:1 (F), to prepare soy-corn milk. Dried flakes of soy-corn milk were analysed for their in vitro digestibility (IVD) and assessed on the performance of rats fed with the test materials. Protein content of the blends increased with the increased amount of soybean in the blend. The IVD of Blend C (88 per cent) was superior to the IVD of all other test blends but was similar to that of casein (90 per cent). Highest weight gain, feed intake, estimated nitrogen intake, PER, BV and NPU were associated with Blend C, and values reported for this blend compared favourably with a casein diet. Implications of the results are discussed in terms of searching for a means of combating malnutrition.
Okro (Abelmoschus esculentus) was grown in the field and green house and fertilized with organic‐based fertilizer (OBF), organic and chemical fertilizers. Okro soups produced from the okro fruits harvested from the various fertilizers treatments were subjected to sensory evaluation tests. Application of varying rates of organic fertilizers on the greenhouse okro plants showed that 10 tonnes per hectare of organic fertilizer led to significant increases in microbial activities in the root zone and it also gave the highest pod yield. In the sensory evaluation test of organically grown okro, panelists preferred organically grown okro soup to the chemically grown variant when they assessed the colour, taste, texture, flavour and drawness. Organically grown okro enjoyed more acceptability than tthe chemically grown. In the field trial,no significant effects of all the treatments were found on some growth parameters assessed. However, application of 5t/ha of OBF led to significant increases in the number of okro pods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
