Abstract

低未利用飼料資源を有効に利用するため,容易に流通できるポリドラムサイロを用い,食品産業廃棄物である茶飲料残渣の飼料調製•貯蔵技術を検討した.茶飲料生産工場から排出された緑茶飲料残渣には乳酸菌は検出されず,好気性細菌および酵母が高い菌数で分布していた.茶飲料残渣に含まれるグルコースなどの可溶性炭水化物(WSC)がきわめて少ないため,飼料作物のようなサイレージ発酵が出来なかった.飼料作物から分離された乳酸菌株<i>Lactobacillus plantarum</i> FG1または市販乳酸菌剤<i>Lactobacillus rhamnosus</i> SN1と<i>Acremonium</i>属菌由来のアクレモニウムセルラーゼを添加して茶飲料残渣サイレージを調製した.乳酸菌とセルラーゼを添加した茶飲料残渣サイレージはpH値が低く,乳酸含量が高い良質なものが調製され,125日間の貯蔵中に変敗しなかった.また,茶飲料残渣サイレージにはタンパク質,機能性成分であるカテキン類,カロチンおよびビタミンEなどが豊富に含まれた.

A method the processing and conserving of tea grounds silage was developed. Tea grounds contained about 106 (cfu/g of fresh matter)aerobic bacteria, 10<sup>3</sup> to 10<sup>4</sup> mould and yeast, but lactic acid bacteria counts were below the limit of detection(⟨10 cfu/g of fresh matter). Water-soluble carbohydrates were consistently at or below the detectable level(0.01 g/kg of dry matter). Lactobacillus plantarum FG1, a strain selected from forage, and Lactobacillus rhamnosus SN1, from a commercial inoculant, were used along with acremonium cellulase(AUS)as additives to tea grounds for silage preparation. After 125 days of fermentation, silages treated with AUS and strain FG1 or SN1 were well preserved and exhibited significantly(P⟨0.05)lower pH values and significantly(P⟨0.05)higher content of lactic acid as compared to the control. All silages showed high contents of protein, tannin, caffeine, carotin and vitamin E. The results confirmed that tea grounds are a potential new resource for livestock feed.
