Materials and methods for producing coffee replicas from individual components are provided herein.

The present invention relates to a method and equipment intended to heat or sterilize liquid such as water, milk, broth, sauces, juices and similar foods and other fluids used in pharmaceutical and cosmetic applications. More specifically this describes a novel approach for continuously heating liquid food or liquid using an electro-magnetic (EM) radiation such as infra-red and other EM radiation sources. It achieves this by conveying radiation from a remote or local source and directing the radiation onto liquid dispersed into tiny droplets in a chamber. Infra-red and other EM radiations have a limitation in that the penetration depth of energy into the product/liquid is very short. Thus, product can be heated only in a thin layer near the periphery surface where the energy strikes. By dispersing liquid in drop droplets, the radiation effectively penetrates the whole body of fluid and consequently heats and destroys bacteria and some spores. The processed fluid then is commercially sterile or has much lower microbial load and hence it has a longer shelf life, under refrigeration.

Cannabis extract subjected to a Pulsed Electric Fields (PEF), High Temperature Short Time (HTST), Heat, High Pressure Processing (HPP) and weak acid preserves the cannabis extract. This process delays, maintains, inhibits, retards and/or reduces the rate of plant derived and/or synthetically derived cannabinoid extract deterioration or degradation and is ideally used in beverages, foods and other consumer products, including a juice product. In addition to preserving the product, the weak acids are preferably citric acid and lemon juice to both inhibit action of oxidative enzymes in the packaged product, but to also inhibit hepatic enzymes in vivo to improve the duration of bio-activity, improve bio-availability, and optimize bio-effects of cannabinoids.

The present invention relates to a process for fast and homogeneously heating a liquid product to a predetermined temperature by means of resistive heating. Sufficient and effective microbial inactivation is achieved upon applying an electrical field strength of between 0.1-5.0 kV/cm for a prolonged period of time, thus by selecting a relatively low electrical field strength and a pulse duration of at least 10 microseconds while the maximum temperature of the liquid product autonomously remains below 92 C. during the resistive heating. The present invention further relates to said process wherein the liquid product is pre-heated prior to subjecting the liquid product to the process. The present invention also relates to the liquid product obtainable by the process according to the invention.
