Food losses and waste: how Brazil is facing this global challenge?
Provedor de dados: Horticultura Brasileira
Autores: Henz,Gilmar Paulo; Porpino,Gustavo.
ABSTRACT By 2017, Brazil seems to have finally awakened to the problem of food loss and waste. In this article, we resume the topic started in the article “Postharvest losses of perishables in Brazil: what do we know so far?” published earlier this year, but now with an emphasis on food losses and waste (FLW). We divided this article into four sections: (a) search for scientific publications on postharvest losses (PHL) and food waste (FW) in Portuguese; (b) social classes and food consumption in Brazil and household food waste; (c) the national legal framework on FLW; and (d) current food security policies and civil society actions on FLW. Google Scholar searches yielded 46,100 records for FW and 16,100 for PHL, but only 37 and 19 records, respectively,...

アミロマイセス麹を新鮮物重量あたり1%添加した ポテトパルプサイレージ，おから，屑パンおよび食品 残渣を加熱滅菌・乾燥して調製飼料を得た.肥育後期 豚(平均体重80kg) を13頭供試し，配合飼料のみを給 与した対照区(6頭)と調製飼料を配合飼料の30%と 置き換えて給与した試験区(7頭)として42日間の肥 育試験を実施した.試験終了後，格付成績と肉質を検 討した.調製飼料は，配合飼料に比べて，粗脂肪含量 が多く，粗タンパク質およびデンプン含量が少なかっ た.飼料嗜好性では，全期間の飼料摂取量に差はなく， 対照区3.03kg/日・頭，試験区3.13kg/日・頭であった. 試験期間において試験豚の体重は，対照区が81.9kgか ら112.8kgに，試験区が79.3kgから109.8kgと増加し， 増体量に差はなかった.また，両試験区間で，出荷体 重，枝肉重量，背脂肪厚，格付等級に差はなかった. ロース芯面積，胸最長筋の肉色，加熱損失率，水分含 量および粗脂肪含量においても対照区と試験区に差は みられなかった.胸最長筋の切断抵抗値は，試験区が対照区より有意に大きい値を示したが，この原因とし て解体後の熟成期間が短かったためと考えられた.皮 下脂肪および筋間脂肪の脂肪酸組成は，両区ともほぼ 同様な構成割合を示し，差は認められなかった. 以上のことから，調製飼料給与は，豚の飼料晴好性， 増体成績.格付成績および肉質に影響を及ぼさなかっ たことから，本試験で用いた調製飼料は豚用配合飼料 に30%まで代替でき，豚用飼料として有用であると考 えられた.

ABSTRACT This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type × available space at the feeder) factorial arrangement among nine pens. Pens had one of three feeder types (concrete bunk, plastic, or wood barrel) and one of three amounts of available space in the feeder (0.33, 0.25, or 0.20 m animal−1). Total dry matter intake/pen, dry matter intake per animal, total weight gain/pen, daily weight gain/animal, and food waste were evaluated. Percentage of time spent at...

Life cycle assessment of a portable assembly biogas unit used for treating food, kitchen and landscape wastes
Provedor de dados: Agricultural Engineering International : The CIGR e-journal
Autores: Samer, Mohamed.
The biogas unit under investigation is a specially designed portable assembly biogas unit and is sought to be widespread and commonly used in Egypt by the Egyptian Environmental Affairs Agency (EEAA). This unit is able to anaerobically treat different types of organic wastes, which are: food waste, kitchen waste, and waste from landscape. The main objective of this study is to perform an environmental impact evaluation of the implementation of this biogas unit. The specific greenhouse gas (GHG) emissions of using the produced biogas from the unit for electricity and heat generation were calculated, where the methodology of life cycle assessment (LCA) was applied. The results show the GHG emissions for each component of the biogas unit and each process...

Fed batch enzymatic saccharification of food waste improves the sugar concentration in the hydrolysates and eventually the ethanol fermentation by Saccharomyces cerevisiae H058
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Yan,Shoubao; Yao,Jianming; Yao,Liming; Zhi,Zhijun; Chen,Xiangsong; Wu,Jingyong.
The enzymatic hydrolysis of food waste by commercially available enzymes and the subsequent ethanol fermentation of the hydrolysates by Saccharomyces cerecisiae H058 were studied in this work. The optimum batch enzymatic conditions were found to be saccharification pH of 4.5, temperature of 55!, glucoamylase concentration of 120 u/g, α-amylase concentration of 10 u/g, solid-liquid ratio of 1: 0.75 (w/w). Fed batch hydrolysis process was started with a solid-liquid ratio of 1: 1 (w/w), with solid food waste added at time lapse of 2 h to get a final solid-liquid ratio of 1: 0.5 (w/w). After 4 h of reaction, the reducing sugar concentration reached 194.43 g/L with a enzymatic digestibility of 93.12%. Further fermentation of the batch and fed batch enzymatic...

Use of food wastes for the production of lactic silage
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Martínez,Ricardo Murray; Mezquita,Pedro Cerezal; Bermúdez,Paulina; Muñoz,Richard Bugueño.
The goal of the present work was to produce lactic silage from food wastes. A factorial 2³ experimental design was applied using the following factors and levels: yogurt inoculum concentration (1 and 15%), sucrose (2 and 15%) and temperature (22 and 35 ºC) and as response variable, the soluble nitrogen content (SNC) at the end of the fermentation was considered. The best SNC output was for the treatment with 1 % of inoculum, 2 % of sucrose and temperature of 22ºC. The increase of SNC with regards to its initial content, from 0.17 % to 1.67 % for protein contents (PC) &lt; 5 % corresponded to 882 % and from 0.65 % to 2.36 % for PC &amp;gt; 5 % represented 263 %. It was possible to produce a lactic silage and keep it stable for up to 30 days, which was...
