Considering four parameters that are% humidity, Ph, Hydroxymethylfurfural (HMF) and the diastase index as indicators of honey quality, a total of 3 repetitions were performed for each parameter in each life zone, making a total of 36 samples in its initial stage considering a constant temperature of 18 ° C and five days after harvest for each sample. In its second stage, the same parameters were discussed with the difference in temperature 30 ° C and 19 days after harvest. Observing that with increasing temperature and days of storage, there is an increase in the hydroxymethylfurfural (HMF) indicator and a decrease in diastase activity; in terms of pH, there was a minimal difference determined that quality in the three bioclimatic zones comply with technical standards. Permissible sanitary measures are demonstrating that the quality and freshness of honey from the Chicmo district is stable and of good quality. Keywords: honey bee, hydroxymethylfurfural (HMF), diastase, climate zones. 1. Introduction Bee honey is a product resulting from the collection of nectar from flowers and other secretions of sweet sap from plants and its maturation in the hive; honey plants produce nectars of different compositions; consequently, honey will present different variations in color, taste, and aroma, etc. The predominance of a melliferous plant in a specific life zone makes honey monofloral. When there is no predominance of a melliferous plant, it makes honey multifloral, hence the difference[1].. To differentiate honey from the bee, its physicochemical, sensory, and biological parameters are studied within the physicochemical parameters we have—Hydroxymethylfurfural (HMF), which is an aldehyde and a furan product of the degradation of sugars. In bee honey, this product of the dehydration of fructose, HMF, is not an intrinsic property of honey. Therefore this harmful compound appears spontaneously and naturally in honey due to the content of water and monosaccharides and acid pH. HMF increases in honey when inadequate heat treatments are performed. This HMF compound is indicative of the conditions it was stored in and the heat treatment received and the age of the honey, therefore defining the quality of the honey. Honey is one of the most widely investigated products due to its unique properties, which are attributed to the influence of the different groups of substances it contains [2]. The transformation from nectar to honey occurs due to physical and chemical changes. The former is mainly due to an evaporation process, in which the nectar loses up to a third of its moisture content during its storage in the hive. The latter is due to the action of enzymes that the workers add to the nectar, such as invertase (sucrose), which hydrolyzes the sucrose present in the nectar to glucose and fructose [3]. Honey can be classified according to its origin (flower honey, honeydew honey, monofloral honey, multifloral honey), the way it has been harvested and processed (honeycomb, taut honey, lumpy honey, ISSN: 2005-4238 IJAST Copyright ⓒ 2020 SERSC 268 International Journal of Advanced Science and Technology Vol. 29, No. 7, (2020), pp. 268-275 honey extracted, pressed honey, crystallized or granulated honey, honey cream), and its intended use (honey table, industrial or bakery honey) [4]. The chemical composition of honey mainly depends on the plant sources from which it is derived, but also on the influence of external factors, such as climate, extraction, and storage management [5]. Honey is known to be a product used in different crops over time due to its nutritional and therapeutic properties, such as its antimicrobial, anti-tumor, anti-inflammatory, and antiviral properties [6]. The annual global production of Apis honey. mellifera, according to the FAO, has been around 1.3 million tons, with an annual growth trend of the order of 2%, reported until 2010. To enter a competitive market in beekeeping, honey must be of quality; the main quality criteria are moisture content, sucrose content, and reducing sugar content, pH, electrical conductivity, ash content, free acidity, and hydroxymethylfurfural (HMF) content of diastase activity [7]. The sensory properties of honey and Physico-chemical characteristics depend primarily on the harvest origin, climatic and ecological conditions, and the method of processing and storage [8]. In the Apurímac province in Peru, there is mega- biodiversity [9] [10] [11], and there are no previous studies related to the physical-chemical quality of the honey produced, these studies are essential to identify the physical-chemical quality and promote their commercialization. 2. Materials and methods 2.1. Location of the origin of the samples The research was carried out on honey samples from three bioclimatic zones of Apurímac; the climate is temperate and warm (Cwb), whose average annual temperature ranges approximately between 10.1 0C and 13.8 0C. The honey samples were extracted from a production stage and a flowering period.
