Definitions

  • the invention relates to a preservative for green forage, the preservative comprising benzoic acid and an active ingredient which is based on formic acid and promotes lactic acid fermen ⁇ tation.
  • green forage can be ensiled by lowering its pH to below 4 by means of acids.
  • the acids may be mineral acids or organic acids or their combinations.
  • Acidic preservative solutions cause drastic corrosion of the apparatus in which the preservative and the raw material of the silage are mixed. Also, in terms of the safety of the users, strong acid solutions are problematic, possibly causing damage to the skin and the eyes, and the acid mist produced may ir ⁇ ritate the respiratory tract. Thus it is highly desirable to find less acidic preservatives which, nevertheless, have high preserving efficacy.
  • Ethyl formate is used according to US patent publication 3,062,659 to retard the sprouting of tubers and. the over-ripening of fruits and vegetables.
  • US patent pub ⁇ lication 4,834,987 describes the use of ethyl formate in the preparation of yogurt, cheese, beer wort, and canned vege ⁇ tables.
  • ethyl formate has been used as an insecticide for the control of the Myzus persicae aphid on packaged lettuce leaves (Journal of Economic Entomology (1984), 77 (3), pp. 569- 573) .
  • the preservative comprising benzoic acid and ethyl formate is superior to preservatives comprising only benzoic acid or ethyl formate.
  • the efficacy of ethyl formate seems to be based on the fact that, in the same manner as formic acid, it selectively pro ⁇ motes lactic acid fermentation. But, in contrast to the situa ⁇ tion when formic acid is used, the pH of the forage is not lowered to below 4 by means of the preservative. When ethyl formate is used, the pH drops at a somewhat slower rate than when formic acid is added, and thereby the above-mentioned disadvantages to people and apparatus are avoided.
  • the preservative contains ethyl formate approx. • 10-98 % by weight and preferably approx. 20-80 % by weight.
  • Benzoic acid is a preservative previously known from FI patent publication 63328, and it is known to control mold fungi in forage mixtures.
  • benzoic acid and especially its salts are poorly soluble in the acid solutions, e.g. formic acid, known in ensiling. Solid state or a tendency to precipitate causes practical inconvenience of many kinds, such as nozzle clogging and sedimentation of the preservative suspension. It has now been shown surprisingly that benzoic acid and its salts dissolve well in ethyl formate, in which case these disad ⁇ vantages can also be avoided.
  • the preservative con ⁇ tains ethyl formate approx. 50-98 % by weight and benzoic acid approx. 2-50 % by weight.
  • Ethyl formate is excellently suited for preservative solutions which contain benzoic acid.
  • the proportion of benzoic acid in the compositions may be approx. 2-50 % by weight, preferably approx. 2-25 % by weight. It is advantageous to use propionic acid together with ethyl formate, since besides preservative properties propionic acid has a dissolving effect on- enzoic acid or its salt.
  • Formic acid can also be used in addition to or together with propionic acid.
  • the preservative contains ethyl formate approx. 50-70 % by weight, benzoic acid approx. 10-30 % by weight, and propionic acid or formic acid approx. 10-30 % by weight. According to another embodiment, it contains ethyl for ⁇ mate approx. 10-30 % by weight, benzoic acid approx. 5-20 % ⁇ by weight, propionic acid approx. 25-50 % by weight, and formic acid approx. 30-60 % by weight.
  • the preservative according to the invention comprising benzoic acid and ethyl formate is suitable to be used for preserving green foraga, i.e. wet preserved grain, mash and green fod ⁇ der.
  • the quantity of ethyl formate per one tonne of- forage may vary within wide limits, depending on the use and on the methods of use. Likewise, the concentrations of ethyl formate may vary within wide limits in preservative compositions in which ethyl formate has been used together with other active ingredients.
  • Especially preferable preservative compositions contain benzoic acid or a salt thereof and ethyl formate together with formic acid and propionic acid.
  • Preservative compositions according to the invention, containing ethyl formate may contain, in addi ⁇ tion to the ingredients mentioned above, also other active ingredients known per se in the ensiling of forage, such as acetic acid, hexanoic acid, heptanoic acid and octanoic acid.
  • the said acids may be in the form of esters or salts.
  • compositions according to the invention may contain besides ethanol, propylene glycol, glycerol, urea, hexamethylene tetra- mine, or an emulsifier.
  • the emulsifier may be a surface active agent, such as a nonionic active agent based on monoglyceride, and a thickening agent type polymer, such as polyvinyl alcohol, can be used as an auxiliary agent of the emulsifier or as a suspending agent.
  • preservative solutions were prepared which contained formic acid, propionic acid and benzoic acid as ac- tive ingredients in addition to ethyl formate.
  • the benzoic acid was first dissolved in ethyl formate and propionic acid before the adding of the other constituents. The values are parts by weight.
  • preservative solutions were prepared in which formic acid, propionic acid and benzoic acid were used as active ingredients in addition to ethyl for ⁇ mate.
  • the samples were tested by defining the concentrations of lactic acid, acetic acid, and the added up ammonium and amine and the results were good.
  • Dimodan LS is a fatty acid monoglyceride
  • the preservative according to the invention contained ethyl formate and benzoic acid in the ratio 80:20, and in addition 2' by weight of C 8 monoglyceride.

Abstract

L'invention concerne un agent de conservation destiné à être utilisé dans la préparation de fourrages verts, l'agent de conservation comprenant un ingrédient actif basé sur l'acide formique et qui favorise la fermentation lactique. La sélectivité de la fermentation lactique est augmentée et ses effets secondaires indésirables tels que la corrosion et les risques pour l'utilisateur et l'environnemnt sont éliminés en choisissant le formiate d'éthyle comme ingrédient actif basé sur l'acide formique. Le formiate d'éthyle peut être utilisé en combinaison avec des agents actifs et des agents auxiliaires habituels, tels que les acides (C1-C10)carboxyliques.
