The present invention relates to additive ingredients for stabilizing food compositions, as well as methods of stabilizing foods and pet foods using thymohydroquinone (THQ), alone or in synergistic combination with other antioxidants. The use of THQ to prevent oxidation of foods and pet foods has been found to be surprisingly effective in stabilizing all representative food matrices, including fats/oils, fatty foods, baked goods, and meat/poultry.

The present invention provides a stable fat-soluble active ingredient composition, microcapsule and process for preparation and use thereof. The fat-soluble active ingredient composition comprises tocopherol, vitamin C palmitate and a fat-soluble active ingredient; wherein the weight ratio of tocopherol to vitamin C palmitate is 2-8:1, the weight ratio of a combination of tocopherol with vitamin C palmitate to the fat-soluble active ingredient is 7-13:100. The present invention obtains a novel antioxidant composition without hidden dangers for improving the stability of the fat-soluble active ingredient by screening a combination of antioxidants and adjusting their proportion and dose.

Food protecting agent composition having a pH of between 5.5 and 7.5 containing at least 2000 mg/l, preferably at least 1800 mg/l of a combination food protecting agent and guanidinium derivatives, particularly to combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), poly(hexamethylendiamine guanidinium chloride), polyetheramines, triethyleneglycol diamine, enzymes, PGPR, amino acids, antioxidants such as humic acids and some natural products like phytotherapeutic plant extracts.

The purpose of any raw and procesesing pruduct for catte, pig etc, fish and chicken is to prevent the development of diseases that might impair the final quality of the products. The system for catte, pig etc, fish and chicken application of food protection products on catte, pig etc, fish and chicken during packing aims to safeguard the health of the catte, pig etc, fish and chicken during the period of storage and transport to the final consumer. Since, moreover, the environmental and economic requirements imposed on modern-day fungicides are continually increasing, with regard, for example, to the spectrum of activity, toxicity, selectivity, application rate, formation of residues, and favorable preparation ability, and since, furthermore, there may be problems, for example, with resistances developing to known active compounds, a constant task is to develop new fungicide agents which in some areas at least have advantages over their known counterparts. Therefore, there is still a need to find and/or develop other bacterial, viral and fungicides for storage disease control. Some of the chemical as such are already known. It is also known, that these compounds can be used as more healthy and applicable material.

Disclosed herein are compositions comprising insoluble alpha-glucan particles having a high degree of crystallinity and small particle size. For example, the alpha-glucan particles can have a degree of crystallinity of at least about 0.65, and/or an average size of less than a micron. At least 50% of the glycosidic linkages of the insoluble alpha-glucan in the disclosed particles are alpha-1,3 glycosidic linkages. Further disclosed are methods of producing insoluble alpha-glucan particles, as well as their use in various applications and products.
