The article is devoted to the study of the main types of retort packaging, as well as polymer and combined materials used for its manufacture. The authors have compiled a classification of retort packaging presented on the modern market, investigated the technological properties of packaging materials, and also determined the requirements for modern retort packaging: resistance to sterilization at a temperature of at least 120°C, steam and moisture resistance, chemical inertia to canned products, tightness, low gas permeability. It has been established that in order to give the retort packaging the required properties, it is made of multilayer polymer or combined materials, each of the layers of which performs certain functions. It is determined that due to the barrier properties of polymer and combined materials with respect to oxygen, retort packaging provides shelf life of canned products up to 5 years, which allows the use of retort packaging made of polymer and combined materials as an alternative to glass and metal packaging. In experimental studies, the composition of the outer layers of modern retort packaging was analyzed and it was concluded that polypropylene or polyethylene terephthalate are most often used, since these polymer materials are thermally and chemically resistant, vapor- and moisture-proof. It is established that materials that are barriers to gases are used as the middle layer – aluminum foil, metallized films, ethylene vinyl alcohol, polyamide. It is proved that polymer co-extrusion, multilayer injection molding or lamination is used for the manufacture of such materials and packaging. The data obtained indicate the high barrier properties of combined packaging materials, therefore, the thermal and chemical stability of the polymer and combined materials used makes it possible to use retort packaging for packing almost all groups of canned products.

The article is devoted to the development of technological parameters for the production of gluten-free pasta, as well as to the study of the influence of physico-chemical factors on the formation of the structure and organoleptic parameters of gluten-free pasta. The authors studied modern approaches to the production of gluten-free food in Kazakhstan. During the study, the main types of raw materials used in the production of gluten-free pasta of functional orientation were identified. For the production of a new product, a reasonable choice of raw materials and functional ingredients was carried out, the formulation and production technology were developed, all temperature and time modes were described, physico-chemical, organoleptic parameters of the new product were studied, a production flowchart was developed. The purpose of the article is to develop the technology of gluten-free pasta enriched on the basis of corn, rice flour and meeting the requirements for specialized food products, with the addition of functional and flavoring ingredients to expand the range of gluten-free products in the Republic of Kazakhstan. In experimental studies, the formula of a new gluten-free paste based on rice and corn flour with the addition of flaxseed flour, soy protein isolate «EdimCo», xanthan gum, dietary fiber (psyllium), Supermak booster was developed. The complex results of organoleptic and physico-chemical parameters of whole-grain flour for the production of new gluten-free pasta are presented. The results of organoleptic and physico-chemical indicators, as well as safety indicators of finished gluten-free pasta are presented. The article presents the technological parameters and time modes of the production process of fresh pasta, including the following basic operations: preparation of raw materials at t = 10 0C, kneading pasta dough at t = 40-45 0C, vacuuming at 40-10 kPa, pressing (extrusion) at 7 min, 10-12 MPa, drying and stabilization at 10-12 MPa, cooling of dried products t = 20-25 0C 4 hours, packaging of finished products at t = 35 0C and relative humidity 70 %.
