Cassava Peel

De Man Rogose and Sharpe (MRS) growth medium is a specific growth medium for lactic acid bacteria (LAB) but has a relatively expensive price. This can be overcome by making alternative media from waste materials. This study used Lactobacilus bulgaricus to represent LAB analyzed for growth. The research aims to formulate alternative media from the waste of cassava peels, banana peels, and tofu whey; determine the best formulation based on the growth parameters of L. bulgaricus; apply the L. bulgaricus in soygurt making and analyze the quality of the resulting yogurt. The results showed the composition of cassava peel: banana peel (75:25 w/w) with the addition of urea 1.5% as the best formu-lation. This formula yields a total LAB of 8.6x106 CFU/mL. The total LAB in the alternative medium was higher than that in MRS control at 1.7x106 CFU/mL. Soygurt produced from LAB as a result of growth from the best media [cassava peel+banana peel (75:25) with the addition of 1.5% urea] resulted in a fat content of 0.9%, total titrated acid 0.6%, protein 8.1 %, pH 4.7, viscosity 14.2 dPas, total dissolved solids 9.7°Brix, brightness (L) 64.3, and yellow-blue (b +) 10.1. These fat content, total titrated acid, and protein are in accordance with SNI for yogurt 2981: 2009.

Either  in its pure form or as a base for a blend-substrate, brackish sludge can be  used as a growth    medium for trees. The objectives of the experiment were (1) to evaluate the  quality of consolidated brackish sludge as a growth medium, (2) to assess the influence of substrate blending on tree growth    (leaf area, tree height, biomass), and (3) to evaluate the need for  substrate blending.    Germinated acorns of the same mother tree were planted in containers and  grown under controlled    conditions. The substrate consisted of pure brackish sludge or of brackish  sludge blended with peat,    sand or wood chips, in stages of 25 volume percentage.    Chemical analysis of the brackish sludge showed a neutral pH, a conductivity  of 3.60 mS/cm and a    sufficient amount of macro elements. The addition of sand contributed to an  accelerated desalination    of the substrate.    The treatments with 100 % sludge and 25 % peat yielded a leaf area, a tree  height and a biomass    which were among the top three growing results. The growing results of the  treatments with 25%    sand and 50% peat were consistently among the top five.    The blending of peat in brackish sludge had no influence on leaf area, tree  height and biomass of    seedlings. The use of wood chips or of more than 25 % sand resulted in a  significant decrease of    these three growth parameters.    Foliage analyses of the trees grown on a substrate containing more than 50%  sand or wood chips    revealed deficits in available nutrients. These deficits manifested  themselves in a loss of leaf area,    tree height and biomass production.    The nutritional status and the growth parameters of oak seedlings on  brackish sludge were    favourable. No influence of the salt and the heavy metal concentrations on  growth was observed.    Consolidated brackish sludge is a suitable growth medium for trees.

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

An experiment was conducted using 20 growing rabbits (5 – 6weeks in age) of mixed breeds and sexes with initial weight of 500 – 650g to evaluate the effect of replacing maize as a source of energy with cassava peel meal (CPM) and cassava leaf meal (CLM) in their diets. The rabbits were randomly allotted to five isonitrogenous and isoenergetic diets. Each dietary treatment was replicated 4-time with individually caged rabbits. The experiment lasted 56days. Dietary treatment did not have effect (P > 0.05) on average daily weight gain, water consumption, feed intake and feed efficiency and carcass charactaristics. The utilization of CPM and CLM fortified with palm-oil sludge with or without amino acid supplementation greatly reduced the cost of producing a unit weight of rabbit (P < 0.001). It was concluded that combination of CPM and CLM can serve as a replacement for maize in rabbit diets without any adverse effect on growth performance and carcass characteristics

In this article a possibility of application of the ultrasonic non-contact method for assessing the quality of yogurt was researched. A prediction assessment was made by an ultrasound based on four parameters – pH, conductivity, fat content, and viscosity. An ultrasonic device was developed to determine the parameters of yoghurt by modified ultrasound sensor available commercially. In order to obtain data for post-processing, a software application was designed for recognizing the ultrasonic signal through the image processing and analysis techniques.<br>The developed algorithms and procedures were applied to determine the distance between the object and the sensor, whereby basic physico-chemical parameters of yogurt could be predicted with the lowest relative error. The working distance was 35 cm for the considered system. The survey results show that the parameters fat content, pH, conductivity, and viscosity of yogurt could be predicted by the proposed system for contactless measurement with accuracy of 94-97%.<br><br>

This study aimed to evaluate the effects of the inclusion of different levels of sun-dried banana peel in the diet for crossbred cows on the quality of Minas fresh cheese and milk. Diets consisted of 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel. Ten cows were assigned to two 5 x 5 Latin squares experimental design. Milk samples were taken from each cow and analyzed for composition. Milk was pasteurized for the production of Minas fresh cheese, which was weighed to determine the yield and analyzed for texture, physical and chemical characteristics and consumer acceptance test. Milk urea nitrogen had a quadratic effect with minimum point at 43.76% replacement of silage with banana peel. The remaining items evaluated in the composition of milk and cheese and the consumer acceptance test were not influenced by diets with banana peel. The replacement of up to 60% sorghum silage with banana peel is a viable alternative because it causes no alteration in physical and chemical composition of milk and Minas fresh cheese, as well as consumer acceptance.

Bacteria Culture

Mixed lactic acid bacteria culture is commonly used in yogurt production. In the present study, two lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophillus) was used as starter culture. Calcium carbonate was added to the starter culture to increase the quality of mixed starter culture of L. bulgaricus and S. thermophillus with ratio of 4:1. The present study was directed to investigate the chemical composition of mixed starter culture with and without calcium carbonat addition. Furthermore, the effect of each starter culture on yogurt product chemical composition was also examined. The pH, lactose, soluble protein and acid content was determined as chemical composition parameters. For starter culture without calcium carbonate addition, the yogurt has pH, lactose, soluble protein and acid content of 4.18–4.39, 4.18–4.39% w/v, 2.88–4.36% w/v and 0.82–0.99% w/v, respectively. While for starter culture with calcium carbonate addition, the yogurt product has pH, lactose, soluble protein and acid content of 4.26–4.37, 1.47–1.75% b/v, 3.42–4.95% w/v and 0.86–1.11% w/v, respectively. Addition of 0.05% w/v calcium carbonate to mixed starter culture gave effect on lactose consumption, where it still can convert lactose to lactic acid up to 45 days of storage. Furthermore, the yogurt product made with starter culture with calcium carbonate addition has higher soluble protein content compared to yogurt made with starter culture without calcium carbonate addition

Cassava Peel

The use of cassava peels as raw material for Sodium Carboxymethyl Cellulose productionCassava peels are abundantly available and may be used as an lowcost cellulose source (80-85% cellulose per weight cassava peel). the study was to evaluate the effect of the concentration of sodium hydroxide, sodium chloroacetate, and temperature reaction on the sodium carboxymethyl cellulose (sodium-CMC) characteristics i.e. yield, purity, and degree of substitution in sodium-CMC preparation.  Sodium-CMC functional group was determined using FTIR spectrophotometer. Cassava peels was dried and grounded to 50 mesh. Lignin was eliminated from cassava peel by extraction of grounded cassava peel with 10% NaOH at 35 °C for 5 h. Cassava peel free lignin was then re-extracted using 10% of acetic acid and sodium chloride at 75 °C for 1 h, thus cellulose free hemicellulose was obtained. Alkalization at 30 °C for 90 min was performed by adding sodium hydroxyde at 10-40% to cellulose using isopropyl alcohol solvent. Following this, etherification was conducted by adding sodium chloroacetate of 1-5 g at 50-80 °C for 6 h. As result, the highest purity of sodium-CMC (96.20%) was obtained from alkalization using 20% of sodium hydroxide and etherification using 3 g sodium chloroacetate at 70 °C. Sodium-CMC yield was 22% and degree of substitution 0.705.Keywords: cassava peel, carboxymethyl cellulose, sodium-CMC, etherification AbstrakKulit singkong merupakan sumber selulosa yang berlimpah dan murah, dengan kadar selulosa 80-85% dari berat kulit singkong.
